O erro apresentado foi o seguinte:

ORA-28361: master key not yet set

Esse erro ocorre, principalmente, quando o PDB de origem não possui criptografia TDE (Transparent Data Encryption) habilitada. Ao ser migrado para o ambiente DBCS, o PDB permanece com o status OPEN_NO_MASTER_KEY, o que impede a correta realização de operações como backup, entre outras funcionalidades que dependem da chave mestra (master key).

Neste artigo, abordaremos brevemente os conceitos fundamentais da criptografia TDE no Oracle, explicaremos por que esse problema ocorre e apresentaremos, na prática, o passo a passo necessário para solucionar o erro ORA-28361 e restabelecer o funcionamento completo do novo PDB no ambiente da Oracle Cloud.

Para um melhor entendimento deste tema, recomenda-se a leitura das seguintes notas técnicas oficiais disponíveis no My Oracle Support. Elas complementam este artigo com orientações detalhadas sobre o erro OPEN_NO_MASTER_KEY e os procedimentos corretos para ativação da chave de criptografia (master key) em PDBs na Oracle Cloud:

  • [OCI-C]: Newly Created PDB Inside The Container Database Shows Wallet Error “OPEN_NO_MASTER_KEY” (Doc ID 2443398.1)
  • Creating and Activating a Master Encryption Key for a PDB (in OCI and OCI-Classic) (Doc ID 2469398.1)
  • WALLET_STATUS is OPEN_NO_MASTER_KEY in new pdb (Doc ID 3028669.1)

Essas documentações oficiais fornecem instruções práticas e são altamente recomendadas, especialmente para ambientes DBCS em OCI que envolvem a criação de novos PDBs sem chave de criptografia ativa.

Para usar o Oracle Transparent Data Encryption (TDE) em um pluggable database (PDB), você deve criar e ativar uma master encryption key (chave mestra de criptografia) para o PDB.


O que é Transparent Data Encryption (TDE)?

O Transparent Data Encryption (TDE) é um recurso do Oracle Database que permite a criptografia de dados sensíveis armazenados em tabelas e tablespaces, com o objetivo de proteger essas informações contra acessos não autorizados.

Após criptografados, os dados são descriptografados de forma transparente no momento do acesso por usuários ou aplicações autorizadas. Isso significa que, para quem tem permissão, a leitura dos dados ocorre normalmente, sem necessidade de ações manuais para descriptografá-los.

O TDE é especialmente eficaz para proteger os dados armazenados em mídia física — também chamados de dados em repouso (data at rest) — em situações como perda, roubo ou acesso indevido ao meio de armazenamento (por exemplo, datafiles no sistema operacional).

Embora o Oracle Database utilize mecanismos robustos de autenticação, autorização e auditoria para proteger os dados internamente, esses mecanismos não se aplicam diretamente aos arquivos físicos de dados no sistema operacional. Para isso, o TDE atua como uma camada adicional de segurança, criptografando os dados diretamente nesses arquivos.

A fim de evitar a descriptografia não autorizada, o TDE armazena as chaves de criptografia em um módulo de segurança externo ao banco de dados, denominado keystore (repositório de chaves).

Como parte da implementação do TDE, é possível configurar o Oracle Key Vault, uma solução que permite o gerenciamento centralizado dos keystores (também chamados de virtual wallets no contexto do Oracle Key Vault) em toda a infraestrutura da organização.

Por exemplo, é possível carregar um software keystore no Oracle Key Vault, migrar o banco de dados para utilizá-lo como keystore padrão, e então compartilhar seu conteúdo com outros nós do Oracle Real Application Clusters (Oracle RAC) — primários e de contingência (standby) —, otimizando assim as operações administrativas diárias em ambientes com dados criptografados.

________

________

O armazenamento da chave mestra (master key) pode ser realizado de duas formas: localmente (dentro do servidor de banco de dados), por meio do Oracle Wallet, ou de maneira centralizada e segura (externa ao servidor de banco de dados), utilizando o Oracle Key Vault. Ambos os mecanismos têm como finalidade armazenar e proteger a chave mestra do banco de dados.

A chave mestra é a chave principal dentro da arquitetura de criptografia TDE (Transparent Data Encryption). Ela é utilizada para criptografar as chaves de dados, também chamadas de data encryption keys, que são as responsáveis diretas por criptografar os dados sensíveis armazenados no banco de dados — como tabelas, tablespaces, backups e outros objetos persistentes.

Essa abordagem de segurança baseada em múltiplos níveis de chaves garante que, mesmo que os arquivos físicos do banco de dados sejam acessados indevidamente, os dados permanecerão protegidos, desde que a chave mestra não esteja acessível.

________

A seguir, apresentaremos o passo a passo para criar e ativar a master key no novo PDB, além de realizar a recriação do wallet em modo AUTOLOGIN.

É importante ressaltar que ambos os passos apresentados anteriormente devem ser executados com o usuário root.

Agora, utilizando o usuário oracle, vamos consultar a visão dinâmica v$encryption_wallet para verificar o status da master key e entender melhor a situação atual do keystore.

         3|PDB                           |READ WRITE|NO

________

Vamos destacar alguns pontos importantes com base no resultado obtido a partir da consulta à view v$encryption_wallet:

A consulta retornou duas linhas. A primeira linha representa o CDB (Container Database), enquanto as demais linhas representam os PDBs (Pluggable Databases).

Neste caso específico, há apenas um PDB criado, portanto foi retornada uma única linha adicional, cujo status é OPEN_NO_MASTER_KEY. Isso indica que a master key ainda não foi criada ou ativada para esse PDB.

Ao executar o comando SHOW PDBS, é possível visualizar tanto o PDB que precisa da ativação da chave quanto o PDB$SEED. Este último, no entanto, não é considerado no processo, pois trata-se de um template padrão utilizado apenas como base para a criação de novos PDBs, não sendo utilizado diretamente para armazenamento de dados ou operações administrativas.

O que significa o status OPEN_NO_MASTER_KEY no Oracle Database?

No Oracle Database, o status OPEN_NO_MASTER_KEY indica que o keystore (repositório de chaves) está aberto, porém nenhuma chave mestra de criptografia (master encryption key) foi criada ou ativada para o banco de dados atual.​

Esse status é comum em ambientes multitenant, onde um Pluggable Database (PDB) foi recentemente criado ou clonado, mas ainda não possui sua própria chave mestra de criptografia. Mesmo que o keystore esteja acessível, a ausência de uma chave mestra impede operações que dependem de criptografia, como backups, exportações de dados e acesso a dados criptografados.​

Por que cada PDB requer sua própria chave mestra?

Em um ambiente multitenant, cada PDB é isolado e pode ter requisitos de segurança distintos. Portanto, o Oracle Database permite que cada PDB tenha sua própria chave mestra de criptografia, mesmo quando todos compartilham um único keystore. Isso proporciona uma gestão mais granular da segurança e facilita operações como rotação de chaves e exportação/importação de PDBs.​

Neste exemplo, estamos utilizando o Oracle Wallet como forma de armazenamento da master key, o que significa que a chave é armazenada localmente, no próprio servidor de banco de dados. Para localizar o caminho do wallet, é possível verificar o arquivo sqlnet.ora ou consultar o parâmetro da instância de banco de dados wallet_root.

$ cat $ORACLE_HOME/network/admin/sqlnet.ora | grep -i WALLET
ENCRYPTION_WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/opt/oracle/dcs/commonstore/wallets/BRAVEO_DB2/tde)))

wallet_root                          string      /opt/oracle/dcs/commonstore/wallets/ORCL_LAB

Com o banco de dados em operação, vamos renomear o arquivo cwallet.sso para cwallet.sso.old. Essa ação desativa o modo de acesso automático (AUTOLOGIN) ao wallet, exigindo que a abertura do keystore seja feita manualmente por meio de senha.

$ ls -la /opt/oracle/dcs/commonstore/wallets/ORCL_LAB/tde/cwallet.sso
-rw------- 1 oracle oinstall 9958 Apr 11 15:13 /opt/oracle/dcs/commonstore/wallets/ORCL_LAB/tde/cwallet.sso

$ mv /opt/oracle/dcs/commonstore/wallets/ORCL_LAB/tde/cwallet.sso /opt/oracle/dcs/commonstore/wallets/ORCL_LAB/tde/cwallet.sso.old

-rw------- 1 oracle oinstall 9958 Apr 11 15:13 /opt/oracle/dcs/commonstore/wallets/ORCL_LAB/tde/cwallet.sso.old

Após a desativação do AUTOLOGIN da wallet, acessaremos o PDB em questão para criar sua própria master key. Nesse passo, será necessário informar a senha do keystore. Para fins de padronização e facilidade de gestão, utilizaremos a mesma senha já definida para a master key do CDB.

SQL> alter session set container=PDB;

Session altered.

Após a criação da master key do PDB, o próximo passo é recriar o AUTOLOGIN da wallet. Para isso, será necessário informar a senha do keystore. A fim de manter a padronização e facilitar a administração, utilizaremos a mesma senha previamente definida para a master key do CDB.

O último passo consiste em realizar um shutdown immediate seguido de um startup da instância do banco de dados. Em seguida, é recomendada uma nova consulta à view v$encryption_wallet para verificar se o status da wallet e da master key foi atualizado corretamente.

SQL> alter session set container=CDB$ROOT;

Session altered.

Entendendo os Arquivos do Oracle Wallet
Para facilitar a compreensão, vamos explicar o papel de cada arquivo presente no diretório onde o Oracle Wallet está armazenado. De forma geral, os dois principais arquivos são:

🔐 ewallet.p12

  • É o arquivo que representa a keystore, ou seja, o repositório seguro onde são armazenadas:
    • Chaves criptográficas (como a master key),
    • Senhas,
    • Certificados digitais e outros dados sensíveis.

🔓 cwallet.sso

  • É o arquivo responsável pelo Single Sign-On (SSO) do wallet.
  • Permite que o banco de dados abra automaticamente o keystore durante o processo de startup, sem necessidade de informar a senha manualmente.

Esses dois arquivos trabalham juntos para garantir segurança e praticidade no gerenciamento das chaves criptográficas dentro do Oracle Database.

$ ls -la | egrep -i '(cwallet\.sso|ewallet\.p12)$'
-rw------- 1 oracle oinstall 9958 Apr 11 15:13 cwallet.sso
-rw------- 1 oracle oinstall 9913 Apr 11 15:12 ewallet.p12

Com todos os passos anteriores concluídos, agora podemos reexecutar o processo de backup para validar a solução implementada.

]]> MySQL Migration: How to Migrate from AWS Amazon Aurora MySQL to OCI HeatWave MySQL with Minimal Downtime https://furushima.com.br/blog/mysql-migration-how-to-migrate-from-aws-amazon-aurora-mysql-to-oci-heatwave-mysql-with-minimal-downtime/ Wed, 26 Mar 2025 21:08:39 +0000 https://furushima.com.br/?p=2736 In this article, we will demonstrate—clearly and practically—how to perform a MySQL database migration with minimal downtime. For this example, our source environment will be Amazon Aurora MySQL 8.0.39, and the target environment will be OCI HeatWave MySQL 8.4.4.

Before initiating the migration procedure, it is essential to ensure that a few infrastructure prerequisites are properly configured and fully operational:

  • AWS and OCI infrastructures must be installed, configured, and up and running.
  • An existing Amazon Aurora MySQL cluster must be currently operational and serving as the production database (source environment).
  • An OCI HeatWave MySQL cluster must already be provisioned and configured, ready to receive the migrated data from Amazon Aurora. This will become the new production database (target environment).
  • Network connectivity between the Amazon Aurora MySQL and the OCI HeatWave MySQL instances must be properly established, specifically allowing traffic on the default MySQL port (3306).

The configuration of these prerequisites will not be covered in detail in this article. If you encounter difficulties during this stage or would like to understand each step more thoroughly, we recommend referring to the official documentation available at the link below:

Oracle – Migration Guide from Amazon Aurora to OCI HeatWave MySQL

This document provides a comprehensive guide, covering everything from setting up the AWS and OCI infrastructures to the detailed procedures that will be briefly summarized in this article. There, you will find in-depth explanations of the concepts that will be simplified here in order to keep this article concise and focused.

Below, we present a high-level flowchart outlining the migration process from a MySQL database currently hosted on AWS Amazon Aurora MySQL to the OCI HeatWave MySQL infrastructure.

The primary goal of this approach is to carry out the migration with the least amount of downtime possible. To achieve this, we will employ a technique that consists of two main stages:

1. Initial Data Migration (Baseline)

In this initial phase, the entire database (i.e., the full dataset) is migrated from the source (AWS Amazon Aurora MySQL) to the target (OCI HeatWave MySQL).
This process is performed using MySQL Shell, a powerful and reliable tool that ensures data consistency and integrity throughout the transfer.

2. Continuous Replication of Differential Data (Delta)

Following the baseline migration, a continuous replication process is established to capture and apply any changes that occur on the source database while the final cutover has not yet been completed.
This delta replication is achieved through the use of binary logs (binlogs)—files that record all transactions executed on the source MySQL database.

To enable this real-time replication between AWS Aurora and OCI HeatWave environments, we will utilize a feature known as the OCI HeatWave MySQL Channel. This feature establishes a direct and reliable connection between the two environments, allowing for ongoing synchronization of transactional data.

In practice, during the migration process, the OCI HeatWave MySQL environment will temporarily operate as a replica (slave) database, faithfully tracking all changes made in the primary (master) environment—Amazon Aurora.

Once all differential (delta) changes have been successfully replicated and both environments are fully synchronized, the only remaining step is to redirect the application servers (e.g., web servers, application servers, middleware, etc.) to the new production environment hosted on OCI HeatWave MySQL.
As a result, the only downtime experienced will be the brief period required to reconfigure these connection endpoints, ensuring a fast, safe, and low-impact transition for end users.

The final outcome will be a fully migrated and operational environment hosted on OCI HeatWave, with complete fidelity to the data and structure of the original Amazon Aurora environment, while also benefiting from the enhanced performance and scalability offered by HeatWave technology.

To enhance clarity and streamline the migration process, this article is divided into two main parts, outlining the key steps required to execute a successful migration from AWS Amazon Aurora MySQL to OCI MySQL HeatWave with minimal downtime.

Part 1: Export (AWS Aurora MySQL) and Import (OCI MySQL HeatWave)

In the first part of this article, we will provide a detailed explanation of how to export the database from the source environment (AWS Amazon Aurora MySQL) using MySQL Shell, a powerful and user-friendly tool that enables fast, secure, and consistent data exports.

Following the export, we will guide you step-by-step through the import process to transfer the extracted data into the target environment (OCI MySQL HeatWave).
This section will also include best practices and recommendations to ensure a successful and reliable import, along with important precautions to preserve data integrity throughout the process.

Part 2: Implementing the OCI HeatWave MySQL Channel (Real-Time MASTER-SLAVE Replication)

In the second part, we will explain in detail how to implement the OCI HeatWave MySQL Channel, which enables the establishment of real-time MASTER-SLAVE replication between the AWS Aurora MySQL (MASTER) and OCI MySQL HeatWave (SLAVE) environments.

This approach ensures that all transactions performed on the AWS Aurora MySQL instance are automatically and continuously replicated in real time to the OCI HeatWave MySQL database using binary logs (binlogs).
In doing so, the OCI HeatWave instance will remain synchronized with the source, allowing the final migration cutover to take place with minimal downtime.

Additionally, we will provide detailed instructions for configuring the replication channel, monitoring its status, and troubleshooting potential synchronization issues during the replication phase.

By the end of this article, you will be equipped with all the necessary information to perform a secure, consistent, and low-impact migration from AWS Amazon Aurora MySQL to OCI MySQL HeatWave.

To facilitate understanding, the following flowchart clearly illustrates the steps that will be demonstrated in practice throughout this article.

Before we begin the practical export and import procedures using MySQL Shell, it is essential to ensure that the following parameters are properly configured and enabled in the source environment (AWS Amazon Aurora MySQL):

gtid_mode = ON
enforce-gtid-consistency = ON
log_bin = ON
binlog_format = ROW
log_slave_updates = ON

These parameters are mandatory to ensure that GTID-based replication (Global Transaction Identifiers) and binary logging are correctly enabled, thereby supporting a reliable, consistent, and compliant migration to the OCI HeatWave MySQL environment.

For more detailed information, refer to the official documentation below:

https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_LogAccess.MySQL.BinaryFormat.html

EXPORT – util.dumpschemas

Export

In this step, we will perform the export (dump) of the npx database.
The resulting dump file will be stored in the directory /DUMP/NPX/.

Additionally, specific parameters will be used to ensure full compatibility of the dump with the target environment, OCI MySQL HeatWave.

util.dumpSchemas(
  ["npx"],
  "/DUMP/NPX/",
  {
    threads: 60,
    ocimds: true,
    compatibility: [
      "skip_invalid_accounts",
      "strip_restricted_grants",
      "ignore_wildcard_grants",
      "strip_definers",
      "strip_invalid_grants",
      "create_invisible_pks"    ],
    consistent: true
  }
);

Explanation of the Parameters Used in the util.dumpSchemas Command

util.dumpSchemas

A MySQL Shell command used to generate a database dump (data export).

["npx"]

Specifies the name of the database to be exported.

"/DUMP/NPX/"

The directory path where the generated dump files will be stored.

threads: 60

Defines the number of parallel threads used during the export. In this case, 60 concurrent processes will be executed to speed up the dump operation.

ocimds: true

Automatically optimizes the export for full compatibility with OCI MySQL Database Service (MDS) or OCI MySQL HeatWave.

Parameters in the compatibility Field:

  • skip_invalid_accounts
    Skips invalid or unsupported user accounts during the export to avoid compatibility issues with the target.
  • strip_restricted_grants
    Removes restricted privileges that are not supported by the target MySQL environment.
  • ignore_wildcard_grants
    Ignores user grants created using wildcards (e.g., %), enhancing security and preventing potential permission issues on the target system.
  • strip_definers
    Removes specific DEFINER clauses from objects such as views, stored procedures, and triggers, preventing errors if the definer user does not exist on the target environment.
  • strip_invalid_grants
    Strips out any invalid or incompatible privilege definitions that may cause conflicts in the destination system.
  • create_invisible_pks
    Automatically creates invisible primary keys on tables that lack one, ensuring compatibility with platforms like OCI HeatWave, which may require primary keys for certain operations.

consistent: true

Ensures that the dump is transactionally consistent, meaning it reflects the exact state of the database at a single point in time, thus avoiding inconsistencies during the export process.

IMPORT – util.loadDump

Import

In this step, we will perform the import of the previously generated dump into the npx database.
The dump files to be imported are located in the directory /DUMP/NPX/.

To speed up the process, we will use 60 parallel threads and the ignoreVersion parameter, which allows the import to proceed even when there are version differences between the source and target MySQL instances.

The target database will be explicitly defined using the schema parameter, which in this case is also named npx.

It is important to note that in MySQL, the term schema is synonymous with database name.

util.loadDump(
  "/DUMP/NPX",
  {
    threads: 60,
    ignoreVersion: true,
	  schema: 'npx'
  }
);

Explanation of the Parameters Used in the util.loadDump Command

util.loadDump

A MySQL Shell command used to load (import) a previously exported dump into the target database.

"/DUMP/NPX"

Specifies the directory path where the dump files to be imported are located.

threads: 60

Indicates the number of parallel threads used during the import process. In this example, 60 concurrent threads will be used to speed up data loading.

ignoreVersion: true

Ignores version differences between the source database (where the dump was generated) and the target database. This allows the import to proceed even if there are minor version mismatches.

schema: 'npx'

Explicitly defines the name of the target database (schema) where the data will be imported. In this case, the target schema is npx.

Now that we have a clear understanding of how to perform the export and import procedures, let’s walk through the practical execution of these steps in a real-world lab environment.

At this point in the article, we have the following consolidated scenario:
We have already performed a database export using the util.dumpSchemas command in the source environment (AWS Amazon Aurora MySQL), and a data import into the target environment (OCI HeatWave MySQL) using the util.loadDump command.

With this, we now move on to the second part of our article, where we will walk through the step-by-step configuration of the OCI HeatWave MySQL Channel.

This configuration will enable the creation of a MASTER/SLAVE replication setup between the two environments mentioned earlier—designating AWS Amazon Aurora MySQL as the MASTER and OCI HeatWave MySQL as its SLAVE replica.

As a result, all transactions executed on the Aurora MySQL database will be automatically replicated in real time to the OCI HeatWave MySQL instance.

At this stage, it is important to ensure that the replication-specific user has already been created in the source environment, that is, in the AWS Amazon Aurora MySQL database.
If this step has not yet been completed, use the commands below to create the user and grant the necessary replication privileges:

CREATE USER 'repuser'@'%' IDENTIFIED BY 'my_password';
GRANT REPLICATION SLAVE ON *.* TO 'repuser'@'%';

Verifying GTID Consistency Before Replication

When performing a database export using the util.dumpSchemas command, a special metadata file named @.json is automatically generated in the directory specified for storing the dump files.

This @.json file contains a comprehensive set of metadata, including critical information about the export process. Among the most important elements within this file is the GTID set (Global Transaction Identifiers), which plays a fundamental role in ensuring data consistency and the accurate tracking of replicated transactions.

It is strongly recommended to review and validate the contents of the @.json file prior to initiating the import process, as the GTID set recorded in this file will later be used during the replication configuration, particularly for the execution of the SET GTID_PURGED statement.

Failure to review or correctly apply the GTID information from this metadata file can result in common errors and may cause serious data consistency issues during the database migration and replication process.

Using the SET_GTID_PURGED Command Correctly

When executing the SET_GTID_PURGED command, it is essential to strictly follow the format shown below to prevent replication errors:


CALL sys.SET_GTID_PURGED("+<gtidSet>");

Practical Example:

CALL sys.SET_GTID_PURGED("+415d143e-3653-30b3-980b-657ad05d72bd:1-44171859");

Special Attention to the “+” Symbol

It is mandatory to include the plus sign (“+”) before the GTID set (<gtidSet>).
This symbol instructs MySQL to append the provided GTID set to the existing one, rather than completely replacing the current GTID values.

This subtle yet critical detail is often overlooked or forgotten, and is one of the most common causes of errors during GTID-based database migration and replication.
Always double-check the presence of the “+” symbol when executing this command to ensure the process completes successfully.

How to Identify Replication Issues in MySQL

The most effective way to identify replication-related issues in MySQL is to connect directly to the replica instance of the MySQL DB System and run specific diagnostic commands.
For this purpose, we recommend using MySQL Shell, which provides a practical and robust interface for administering MySQL environments.

Replication issues are typically reported in four main locations:

1. SHOW REPLICA STATUS\G Command

This is the most commonly used method, though not the most comprehensive.
It provides a quick overview of the replication status, particularly useful for identifying problems with the replication threads—namely, SQL_thread and IO_thread.

2. performance_schema.replication_connection_status Table

This table should be consulted when the IO_thread (responsible for communication between the master and the replica) is not functioning properly.
It provides detailed information about connection failures with the master server.

3. performance_schema.replication_applier_status_by_coordinator and replication_applier_status_by_worker Tables

These two tables offer detailed diagnostics for issues related to the SQL_thread, which is responsible for applying replication events received from the master.
They are especially useful for identifying failures or stalls in the event applier process.

4. MySQL Error Log

The most critical and detailed errors are logged directly in the MySQL error log, which can also be accessed via the performance_schema.error_log table.
This method is particularly helpful in cloud environments, such as MySQL HeatWave Database Service, allowing for detailed tracking and analysis of replication issues.

By leveraging these methods together, you can quickly and accurately diagnose any replication problem occurring in your MySQL environment, speeding up resolution and restoring proper replication as efficiently as possible.

       prio,
       error_code,
       data

WHERE  subsystem = 'Repl'
       AND prio = 'Error'
ORDER  BY 1 DESC;

🔸 channel

Identifies the name of the replication channel, along with the specific thread or worker number.

Example: replication_channel (1)

🔸 io_state

Indicates the state of the channel related to binlog connection and transfer (I/O Thread).

Possible values:

  • ON → The connection is active and functioning normally.
  • OFF → The connection is inactive or disconnected.

🔸 sql_state

Reflects the state of transaction application (SQL Thread).

Possible values:

  • ON → Transactions are being applied correctly.
  • OFF → Transaction application is halted or experiencing issues.

🔸 latency

Represents the overall replication lag, indicating the delay between the last GTID received by the replica and the last GTID actually applied.

Example: 2.56 d means that channel (1) is 2.56 days behind in applying transactions.

🔸 time_to_relay_log

The time it takes for the replica to write the received data to the relay log.

This value is typically very small.
Example: 20.00 µs (microseconds), which is an acceptable and fast response time.

🔸 apply_time

The time taken by the replica to apply the last transaction to its local database.

Example: 1.86 ms, 5.18 ms — these are considered good and acceptable values.

🔸 last_queued_transaction

Indicates the last GTID received (queued) from the master.

🔸 last_applied_transaction

Indicates the last GTID successfully applied by the replica.

The difference between this GTID and the last_queued_transaction represents the current replication lag.

  • SERVICE_STATE:
    Indicates the current state of the replica’s I/O thread. Possible values include:
    • ON: The connection is active.
    • OFF: The connection is inactive.
    • CONNECTING: The replica is attempting to connect to the source.

Connection Identification

  • CHANNEL_NAME:
    Name of the replication channel associated with this connection.
  • SOURCE_UUID:
    The unique universal identifier (UUID) of the source server — useful for tracking the origin of the replication.

Transaction Information

  • RECEIVED_TRANSACTION_SET:
    The set of GTIDs (Global Transaction Identifiers) representing all transactions received by the replica.
  • LAST_QUEUED_TRANSACTION:
    The GTID of the last transaction queued in the relay log.
  • LAST_QUEUED_TRANSACTION_ORIGINAL_COMMIT_TIMESTAMP:
    Timestamp when the last queued transaction was originally committed on the source server.
  • LAST_QUEUED_TRANSACTION_IMMEDIATE_COMMIT_TIMESTAMP:
    Timestamp when the last queued transaction was committed on the immediate upstream source (e.g., an intermediate master).
  • LAST_QUEUED_TRANSACTION_START_QUEUE_TIMESTAMP:
    Timestamp indicating when the I/O thread started queuing the last transaction.
  • LAST_QUEUED_TRANSACTION_END_QUEUE_TIMESTAMP:
    Timestamp indicating when the transaction was fully queued into the relay log.

Replication Heartbeats

  • LAST_HEARTBEAT_TIMESTAMP:
    Timestamp of the last heartbeat signal received from the source server, confirming the connection is alive even in the absence of recent events.
  • COUNT_RECEIVED_HEARTBEATS:
    Total number of heartbeat signals received since the replica was last restarted or reset.

Error Information

  • LAST_ERROR_NUMBER:
    The error code of the most recent I/O thread failure. A value of 0 indicates no errors.
  • LAST_ERROR_MESSAGE:
    The error message associated with the most recent failure. An empty string indicates no recent errors.
  • LAST_ERROR_TIMESTAMP:
    Timestamp of the last I/O thread error occurrence.

Timestamps for Current Transactions

  • QUEUEING_TRANSACTION:
    The GTID of the transaction currently being queued.
  • QUEUEING_TRANSACTION_ORIGINAL_COMMIT_TIMESTAMP:
    Timestamp when the currently queued transaction was committed on the original source server.

]]> Migração MySQL: Como migrar do AWS Amazon Aurora MYSQL para OCI HeatWave MYSQL com mínimo downtime. https://furushima.com.br/blog/migracao-mysql-como-migrar-do-aws-amazon-aurora-mysql-para-oci-heatwave-mysql-com-minimo-downtime/ Tue, 25 Mar 2025 12:03:30 +0000 https://furushima.com.br/?p=2676 Neste artigo vamos demonstrar, de maneira clara e prática, como realizar uma migração entre bancos de dados MySQL com o mínimo possível de downtime (indisponibilidade). Para este exemplo, nosso ambiente de origem (source) será o Amazon Aurora MySQL 8.0.39, e o ambiente de destino (target) será o OCI HeatWave MySQL 8.4.4.


Antes de iniciarmos o procedimento de migração, é necessário garantir que alguns pré-requisitos de infraestrutura estejam devidamente configurados e operacionais:

  1. Infraestrutura AWS e OCI já instaladas, configuradas e operacionais.

  2. Cluster Amazon Aurora MySQL já existente e atualmente em operação como banco de produção (ambiente de origem ou source).

  3. Cluster OCI HeatWave MySQL já criado e configurado, pronto para receber os dados migrados do Amazon Aurora. Este será o novo ambiente de produção (ambiente de destino ou target).

  4. Conectividade devidamente configurada entre o Amazon Aurora MySQL e o OCI HeatWave MySQL, especificamente na porta padrão do MySQL (3306).


Os detalhes sobre a configuração dos pré-requisitos não serão abordados neste artigo. Caso você tenha dificuldades durante essa etapa, ou deseje compreender melhor cada passo mencionado, recomenda-se consultar a documentação oficial, cujo link está disponível abaixo:

https://www.oracle.com/a/ocom/docs/mysql/amazon-aurora-to-mysql-heatwave-on-aws-migration.pdf


Este documento é um guia completo que aborda desde a criação das infraestruturas AWS e OCI até os procedimentos que serão resumidamente demonstrados neste artigo. Lá você encontrará explicações detalhadas sobre conceitos que aqui serão simplificados, a fim de manter este artigo objetivo e direto.


A seguir apresentamos um fluxograma macro detalhando como será realizado o processo de migração de um banco de dados MySQL que atualmente está hospedado na infraestrutura AWS Amazon Aurora MySQL para a infraestrutura OCI HeatWave MySQL.


O objetivo principal dessa abordagem é realizar a migração com o menor downtime possível. Para alcançar esse objetivo, utilizaremos uma técnica que consiste basicamente em duas etapas principais:

  1. Migração inicial dos dados (Baseline)
    Nesta fase inicial, o banco de dados completo (ou seja, a base integral) é migrado da origem (AWS Amazon Aurora MySQL) para o destino (OCI HeatWave MySQL). Este procedimento será realizado com o auxílio do MySQL Shell, uma ferramenta robusta que garante consistência e integridade na transferência dos dados.

  2. Replicação contínua dos dados diferenciais (Delta)
    Após a migração inicial, haverá uma replicação contínua das alterações que ocorrerem na origem enquanto a migração final não é concluída. Essa replicação diferencial é realizada por meio dos binlogs (binary logs), arquivos que registram todas as transações realizadas no banco de dados de origem.


Para viabilizar essa replicação em tempo real entre os ambientes AWS Aurora e OCI HeatWave, será utilizado o recurso conhecido como OCI HeatWave MySQL Channel, que estabelece uma conexão direta e confiável entre os ambientes, tornando o OCI HeatWave MySQL uma réplica ativa (também conhecida como réplica read/write) do Amazon Aurora MySQL.

Na prática, durante o processo, o ambiente OCI HeatWave MySQL funcionará temporariamente como um banco de dados replicado (Slave) que acompanhará fielmente as alterações feitas no ambiente Master (Amazon Aurora). Quando todas as replicações diferenciais estiverem em sincronia, restará apenas apontar os servidores de aplicação (servidores web, appservers, middlewares etc.) para o novo ambiente de produção OCI HeatWave MySQL. Dessa forma, o único tempo de indisponibilidade (downtime) será o necessário para realizar os ajustes desses apontamentos nos servidores de aplicação, garantindo uma transição rápida, segura e com mínimo impacto para os usuários finais.

O resultado final será um ambiente totalmente migrado e operacional na infraestrutura OCI HeatWave, mantendo-se fiel às características e dados originais do Amazon Aurora, com ganhos adicionais em desempenho e escalabilidade proporcionados pela tecnologia HeatWave.

Neste artigo, dividiremos o conteúdo em duas partes principais, com o objetivo de tornar mais clara a compreensão das etapas necessárias para realizar uma migração eficiente entre os ambientes AWS Amazon Aurora MySQL e OCI MySQL HeatWave, mantendo o mínimo de indisponibilidade possível.

Parte 1: Exportação (AWS Aurora MySQL) e Importação (OCI MySQL HeatWave)
Na primeira parte deste artigo, explicaremos detalhadamente como realizar o processo de exportação dos dados do banco de dados AWS Amazon Aurora MySQL (ambiente de origem) utilizando o MySQL Shell, uma ferramenta poderosa e prática que permite exportações rápidas, seguras e consistentes dos dados.

Após a exportação, demonstraremos passo a passo como realizar o processo inverso, ou seja, a importação dos dados extraídos para o ambiente destino (OCI MySQL HeatWave). Nesta etapa, abordaremos também as melhores práticas e recomendações para garantir uma importação bem-sucedida, além dos cuidados necessários para garantir a integridade dos dados importados.

Parte 2: Implementação do OCI HeatWave MySQL Channel (Replicação MASTER-SLAVE em tempo real)
Na segunda parte do artigo, abordaremos de forma detalhada como implementar o OCI HeatWave MySQL Channel, que permitirá estabelecer uma replicação em tempo real no modelo MASTER-SLAVE entre os bancos de dados AWS Aurora MySQL (MASTER) e OCI MySQL HeatWave (SLAVE).

Esse método garante que todas as transações realizadas no ambiente AWS Aurora MySQL sejam replicadas automaticamente e em tempo real para o ambiente OCI MySQL HeatWave, utilizando para isso os binlogs (binary logs). Dessa forma, o OCI MySQL HeatWave se manterá sempre atualizado com o ambiente de origem, permitindo que a migração final ocorra com o mínimo de downtime possível.

Além disso, vamos apresentar orientações sobre a configuração do canal de replicação, monitoramento do status e solução de possíveis problemas de sincronização durante a replicação.

Dessa maneira, ao final deste artigo, você terá todas as informações necessárias para realizar a migração segura, consistente e com mínimo impacto operacional entre AWS Amazon Aurora MySQL e OCI MySQL HeatWave.

Para facilitar o entendimento, apresentamos abaixo um fluxograma que ilustra claramente as etapas que serão demonstradas na prática ao longo deste artigo.

Antes de iniciarmos o procedimento prático de exportação e importação utilizando o MySQL Shell, é fundamental garantir que os seguintes parâmetros estejam devidamente configurados e ativados no ambiente de origem (SOURCE), ou seja, no AWS Amazon Aurora MySQL:


gtid_mode = ON
enforce-gtid-consistency = ON
log_bin = ON
binlog_format = ROW
log_slave_updates = ON

Esses parâmetros são obrigatórios para assegurar que a replicação baseada em GTID (Global Transaction Identifiers) e os logs binários estejam corretamente habilitados, garantindo uma migração confiável, consistente e adequada ao ambiente OCI HeatWave MySQL.

Para mais detalhes consulte a documentação abaixo :

https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_LogAccess.MySQL.BinaryFormat.html



EXPORTAÇÃO – EXPORT – util.dumpschemas

Exportação: Nesta etapa realizaremos a exportação (dump) do banco de dados npx. O arquivo gerado será armazenado no diretório /DUMP/NPX/. Além disso, serão utilizados parâmetros específicos que garantem total compatibilidade do dump com o ambiente de destino, o OCI MySQL HeatWave.

util.dumpSchemas(
  ["npx"],
  "/DUMP/NPX/",
  {
    threads: 60,
    ocimds: true,
    compatibility: [
      "skip_invalid_accounts",
      "strip_restricted_grants",
      "ignore_wildcard_grants",
      "strip_definers",
      "strip_invalid_grants",
      "create_invisible_pks"    ],
    consistent: true
  }
);


Explicação dos parâmetros utilizados no comando util.dumpSchemas:

  • util.dumpSchemas
    Comando do MySQL Shell usado para gerar um dump (exportação dos dados).
  • ["npx"]
    Indica o nome do banco de dados que será exportado.
  • "/DUMP/NPX/"
    Diretório (pasta) onde serão armazenados os arquivos do dump gerado.
  • threads: 60
    Número de threads simultâneas usadas na exportação. Neste caso, serão usados 60 processos paralelos para acelerar a geração do dump.
  • ocimds: true
    Otimiza automaticamente a exportação para garantir total compatibilidade com o ambiente OCI MySQL Database Service (MDS) ou OCI MySQL HeatWave.
  • Parâmetros do campo compatibility:
    • skip_invalid_accounts
      Ignora contas de usuários inválidas ou não compatíveis com o destino.
    • strip_restricted_grants
      Remove permissões restritas que não são suportadas pelo banco de dados de destino.
    • ignore_wildcard_grants
      Ignora permissões de usuários criadas com curingas (%), aumentando a segurança e evitando problemas no destino.
    • strip_definers
      Remove definições específicas de usuários (DEFINER) em objetos como views, stored procedures e triggers, evitando erros caso esses usuários não existam no destino.
    • strip_invalid_grants
      Remove permissões inválidas ou incompatíveis com o destino.
    • create_invisible_pks
      Cria automaticamente chaves primárias invisíveis nas tabelas que não possuem chave primária, garantindo compatibilidade com ambientes como OCI HeatWave.
  • consistent: true
    Garante que o dump seja consistente, refletindo exatamente o estado do banco de dados em um único momento específico, evitando inconsistências durante a exportação.



IMPORTAÇÃO – IMPORT – util.loadDump

Importação: Nesta etapa será realizada a importação do dump previamente gerado para o banco de dados npx. Os arquivos a serem importados estão localizados no diretório /DUMP/NPX/. Para acelerar esse processo, utilizaremos 60 threads em paralelo e o parâmetro ignoreVersion, permitindo a importação mesmo em versões diferentes do MySQL. O banco de dados de destino será explicitamente definido pelo parâmetro schema, que neste caso também se chama npx. Vale lembrar que no MySQL, o termo schema representa o nome do banco de dados.

util.loadDump(
  "/DUMP/NPX",
  {
    threads: 60,
    ignoreVersion: true,
	  schema: 'npx'
  }
);

Explicação dos parâmetros utilizados no comando util.loadDump:

  • util.loadDump
    Comando do MySQL Shell utilizado para carregar (importar) um dump previamente exportado para o banco de dados.
  • "/DUMP/NPX"
    Diretório (pasta) onde estão armazenados os arquivos do dump que será importado.
  • threads: 60
    Número de processos paralelos utilizados durante a importação. Neste exemplo, 60 threads serão usadas para acelerar o carregamento dos dados.
  • ignoreVersion: true
    Ignora diferenças de versão entre o banco de dados original (onde o dump foi gerado) e o banco de dados de destino. Isso permite importar o dump mesmo se houver pequenas diferenças de versão.
  • schema: 'npx'
    Define explicitamente o nome do banco de dados (schema) onde os dados serão importados. Nesse caso, o schema destino será npx.

Agora que já entendemos como realizar o processo de exportação e importação do banco de dados, vamos acompanhar, na prática, a execução desses procedimentos em um ambiente real de laboratório.

Neste ponto do artigo, temos o seguinte cenário consolidado: já realizamos uma exportação do banco de dados utilizando o comando util.dumpSchemas no ambiente de origem (AWS Amazon Aurora MySQL) e uma importação desses dados no ambiente de destino (OCI HeatWave MySQL) utilizando o comando util.loadDump.


Com isso, partiremos agora para a segunda parte do nosso artigo, onde faremos passo a passo a configuração do OCI HeatWave MySQL Channel. Essa configuração permitirá criar uma replicação no modelo MASTER/SLAVE entre os dois ambientes mencionados, transformando o AWS Amazon Aurora MySQL no banco de dados MASTER e o OCI HeatWave MySQL em sua réplica (SLAVE). Assim, todas as transações realizadas no Aurora MySQL serão automaticamente replicadas em tempo real para o OCI HeatWave MySQL.




Nesta etapa, é importante garantir que o usuário específico para replicação já tenha sido criado no ambiente SOURCE (origem), ou seja, no banco de dados AWS Amazon Aurora MySQL. Caso ainda não tenha sido feito, utilize os comandos abaixo para criar o usuário e conceder as permissões necessárias para replicação:

CREATE USER 'repuser'@'%' IDENTIFIED BY 'minha_senha_forte';
GRANT REPLICATION SLAVE ON *.* TO 'repuser'@'%';








































Certificando que GTID esta no ponto correto





Ao realizar um dump (exportação) utilizando o comando util.dumpSchemas, será gerado automaticamente um arquivo especial chamado @.json no diretório escolhido para armazenar o dump.





Este arquivo @.json é um arquivo de metadados contendo diversas informações essenciais sobre o dump realizado. Entre as informações mais relevantes presentes neste arquivo está o conjunto GTID (Global Transaction ID), que é crucial para garantir consistência e rastreamento correto das transações replicadas.





Recomenda-se sempre verificar e consultar esse arquivo antes da importação (load), pois o GTID ali informado será utilizado posteriormente para configuração correta da replicação e execução do comando SET_GTID_PURGED.





Ignorar ou não utilizar corretamente o arquivo @.json pode levar a erros comuns e sérios problemas de consistência na migração e replicação do banco de dados.

Ao utilizar o comando SET_GTID_PURGED, siga rigorosamente o modelo abaixo para garantir que não ocorram erros na replicação dos dados:





CALL sys.SET_GTID_PURGED("+<gtidSet>");





Veja um exemplo prático:





CALL sys.SET_GTID_PURGED("+415d143e-3653-30b3-980b-657ad05d72bd:1-44171859");





Atenção especial ao sinal “+”:
Note que é obrigatório utilizar o sinal “+” antes do conjunto GTID (<gtidSet>). Esse sinal indica ao MySQL que o GTID fornecido deve ser adicionado (“append”) ao conjunto já existente, em vez de substituir completamente os valores atuais.





Essa pequena particularidade é extremamente importante e frequentemente ignorada ou esquecida, sendo um dos principais motivos de erros durante a migração e replicação dos dados utilizando GTIDs. Sempre verifique cuidadosamente a presença do sinal “+” ao executar este comando.










Como identificar problemas de replicação no MySQL?


A forma mais eficaz de identificar problemas relacionados à replicação no MySQL é conectar diretamente na instância réplica do MySQL DB System e executar comandos específicos de diagnóstico. Para realizar esses comandos, recomendamos o uso da ferramenta MySQL Shell, que oferece uma interface prática e robusta para administração do MySQL.





Normalmente, os problemas relacionados à replicação são reportados em quatro locais diferentes:





    

  1. Comando SHOW REPLICA STATUS\G
    Este é o método mais utilizado, porém não é o mais completo. Ele oferece uma visão geral do status da replicação, apresentando rapidamente se há algum problema com os threads (SQL_thread ou IO_thread).

    2. 




  2. Tabela performance_schema.replication_connection_status
    Esta tabela deve ser consultada quando o IO_thread (responsável pela comunicação entre Master e Replica) não estiver funcionando corretamente. Nela estarão disponíveis detalhes sobre possíveis falhas de conexão com o servidor mestre (Master).

    3. 




  3. Tabelas performance_schema.replication_applier_status_by_coordinator e performance_schema.replication_applier_status_by_worker
    Estas duas tabelas fornecem informações detalhadas sobre problemas relacionados ao SQL_thread, responsável pela aplicação dos eventos recebidos do servidor mestre (Master). São extremamente úteis quando há falha ou travamento do processo que aplica os comandos SQL.

    4. 




  4. Arquivo de log de erros do MySQL (error log)
    Os erros mais críticos ou detalhados são registrados diretamente no arquivo de log de erros do MySQL, acessível também através da tabela performance_schema.error_log.
    Esse método é especialmente útil em ambientes na nuvem, como no serviço MySQL HeatWave Database Service, permitindo uma fácil análise e acompanhamento detalhado dos problemas de replicação.


    5. 






Utilizando esses métodos em conjunto, é possível identificar rapidamente e com precisão qualquer problema de replicação que esteja ocorrendo no seu ambiente MySQL, agilizando assim a correção e restabelecendo rapidamente o funcionamento correto da replicação.

2. Configurações Obrigatórias no AWS Aurora MySQL (Source):





Habilite e verifique rigorosamente os seguintes parâmetros:





gtid_mode = ON
enforce-gtid-consistency = ON
log_bin = ON
binlog_format = ROW
log_slave_updates = ON





Esses parâmetros garantem a viabilidade técnica e a integridade dos dados durante a replicação.





Mais detalhes sobre essas configurações estão disponíveis na Documentação Oficial AWS.





3. Exportação e Importação com MySQL Shell:





Utilize o MySQL Shell como ferramenta principal para exportação/importação.





Garanta que o processo seja executado seguindo boas práticas indicadas no decorrer do artigo, incluindo geração e manipulação correta dos arquivos JSON para GTID.





4. Configuração do Usuário de Replicação:





Confirme que o usuário de replicação está criado corretamente no AWS Aurora MySQL (origem) e possui as permissões adequadas.





Um exemplo prático para criação do usuário repuser foi detalhado ao longo deste artigo, fornecendo um guia completo para evitar problemas de permissão.





5. Implementação do Canal de Replicação OCI HeatWave MySQL:





Neste passo crucial, verifique a congruência dos GTIDs entre origem e destino utilizando o arquivo .json gerado durante o export.





Caso necessário, ajuste o GTID utilizando o comando SET_GTID_PURGED, garantindo que a replicação delta inicie no ponto correto.





Atenção especial ao detalhado passo a passo fornecido anteriormente para implementação eficaz e segura do canal de replicação HeatWave na OCI.





6. Troubleshooting e Monitoramento:





O artigo forneceu insights valiosos para solucionar problemas comuns durante a migração.





Utilize os scripts e exemplos fornecidos para identificar rapidamente qualquer desvio ou problema.

										A segurança dos backups é um dos principais pilares na administração de bancos de dados. Ter uma cópia externa garante a recuperação dos dados em caso de falhas. Neste artigo, vamos demonstrar como configurar o backup do SQL Server utilizando o Rclone para enviar os arquivos para um bucket da Oracle Cloud.





Criando o Bucket na Oracle Cloud





    

  1. Acesse a Oracle Cloud: https://cloud.oracle.com
    2. 




  2. Navegue até a seção de Armazenamento e crie um Bucket
    3. 











    3. Salve o namespace gerado, pois ele será necessário para configuração





    

  1. 
















Gerando as Chaves de Acesso





    

  1. Acesse a Oracle Cloud e crie uma Secret Key e Access Key
    2. 
















Anote a Secret Key no momento da geração, pois não será exibida novamente










Instalando e Configurando o Rclone no Windows





1. Download do Rclone





Baixe a versão mais recente do Rclone para Windows: https://rclone.org/downloads/










2. Configuração Inicial do Rclone





    

  1. Abra o Prompt de Comando (CMD)
    2. 




  2. Digite rclone.exe config e siga os passos abaixo:

      

    • Escolha n para criar uma nova configuração
      • 




    • Nomeie a configuração como oci_s3
      • 




    • Escolha s3 como tipo de armazenamento
      • 




    • Selecione Other como provedor
      • 




    • Escolha 1 para inserir manualmente as credenciais
      • 




    • Insira sua Access Key e Secret Key
      • 




    • Informe a região (exemplo: sa-saopaulo-1)
      • 




    • Configure o endpoint no formato: https://NAMESPACE.compat.objectstorage.REGION.oraclecloud.com
      • 




    • O restante da configuração pode manter default, apenas pressionando enter.
      • 

    

    3. 











    

  1. 






3. Teste a sua configuração















Criando o Script PowerShell para Backup Automático





Agora que o Rclone está configurado, podemos criar um script PowerShell para automatizar o backup e o envio para a Oracle Cloud.





Exemplo de Script PowerShell:





Este script tem como entrada:





    

  • backupFolder : Para o local onde está o backup
    • 




  • RcloneConfig: Onde está o config do Rclone, caso deseje mudar.
    • 




  • bucketName: Caminho do Bucket a ser criado
    • 




  • remote: Qual configuração irá utilizar do Rclone, lembra aquele oci_s3?
    • 




  • logDir: Diretorio de logs.
    • 






[Console]::OutputEncoding = [System.Text.Encoding]::UTF8

# Diretório de backup
$backupFolder = "K:\BACKUPS\LOG"
$RcloneConfig = "C:\zabbix\scripts\rclone.conf"

# Nome do bucket na OCI
$bucketName = "BACKUP-MSSQL-OCI/LOG"

# Nome do remote configurado no Rclone
$remote = "oci_s3"

# Diretório de logs
$logDir = "C:\zabbix\scripts\logs"

# Criar diretório de logs se não existir
if (!(Test-Path -Path $logDir)) {
    New-Item -ItemType Directory -Path $logDir | Out-Null
}

# Criar nome do log por dia
$logFile = "$logDir\backup_LOG_$(Get-Date -Format 'yyyyMMdd_HHmm').log"

# Data e hora atual
$date = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
Write-Output "[$date] Iniciando verificação e sincronização..." | Out-File -Append -Encoding utf8 $logFile

# Função para verificar se um arquivo está em uso
function Test-FileInUse {
    param([string]$filePath)
    try {
        $file = [System.IO.File]::Open($filePath, 'Open', 'Read', 'None')
        if ($file) { $file.Close() }
        return $false  # Arquivo não está em uso
    } catch {
        return $true   # Arquivo está em uso
    }
}

# Definir os diretórios do dia atual e do dia anterior
$today = Get-Date -Format 'yyyyMMdd'
$yesterday = (Get-Date).AddDays(-1).ToString('yyyyMMdd')
$todayDir = Join-Path $backupFolder $today
$yesterdayDir = Join-Path $backupFolder $yesterday

# Lista de diretórios válidos
$validDirs = @()
if (Test-Path $todayDir) { $validDirs += $todayDir }
if (Test-Path $yesterdayDir) { $validDirs += $yesterdayDir }

# Criar uma lista de arquivos prontos para upload
$filesToSync = @()
foreach ($dir in $validDirs) {
    Get-ChildItem -Path $dir -Recurse -File | ForEach-Object {
        $filePath = $_.FullName
        if (-not (Test-FileInUse $filePath)) {
            $filesToSync += $filePath
        } else {
            Write-Output "[$date] Ignorando (arquivo ainda em uso): $filePath" | Out-File -Append -Encoding utf8 $logFile
        }
    }
}

# Se houver arquivos prontos, enviar para o OCI
if ($filesToSync.Count -gt 0) {
    Write-Output "[$date] Enviando $( $filesToSync.Count ) arquivos para OCI..." | Out-File -Append -Encoding utf8 $logFile

    # Criar diretório no bucket
    $bucketPathToday = "$remote`:$bucketName/$today"
    $bucketPathYesterday = "$remote`:$bucketName/$yesterday"

    # Enviar arquivos com Rclone
    if (Test-Path $todayDir) {
        & "C:\Program Files\Rclone\rclone.exe" copy "$todayDir" "$bucketPathToday" --config "$RcloneConfig" --progress --transfers 8 --checkers 16 --fast-list --log-file="$logFile" --log-level DEBUG
    }
    if (Test-Path $yesterdayDir) {
        & "C:\Program Files\Rclone\rclone.exe" copy "$yesterdayDir" "$bucketPathYesterday" --config "$RcloneConfig" --progress --transfers 8 --checkers 16 --fast-list --log-file="$logFile" --log-level DEBUG
    }

    Write-Output "[$date] Sincronização concluída!" | Out-File -Append -Encoding utf8 $logFile
} else {
    Write-Output "[$date] Nenhum arquivo disponível para sincronização." | Out-File -Append -Encoding utf8 $logFile
}






Agendando o Backup no SQL Server Agent





    

  1. Abra o SQL Server Management Studio (SSMS)
    2. 




  2. Navegue até SQL Server Agent > Jobs
    3. 




  3. Abra o Job de Backup que é necessário criar o upload.
    4. 




  4. Escolha CmdExec como tipo de comando e insira o script acima (Ajustado ao seu ambiente).
    5. 




  5. Insira a chamada do script powershell C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File "C:\scripts\furushima_send_oci_log.ps1"
    6. 




  6. Defina um agendamento adequado (diário, horário, etc.)
    7. 











E Então…. estão nossos backups feito upload para o OCI S3, de forma automatizada pós backup! 🙂
