Migrating a Standby DB Instance

Scenarios

You can migrate a standby DB instance to another AZ in the same region as the original AZ.

-
  • Primary/standby instances running MySQL 5.6, 5.7, or 8.0 support standby instance migration to another AZ.
  • DDL operations and scheduled events will be suspended during migration. To prevent service interruptions, perform the migration during off-peak hours.
+
  • Primary/standby instances running MySQL 5.7, or 8.0 support standby instance migration to another AZ.
  • DDL operations and scheduled events will be suspended during migration. To prevent service interruptions, perform the migration during off-peak hours.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click Service List. Under Database, click Relational Database Service. The RDS console is displayed.
  4. On the Instances page, locate the target DB instance and choose More > Migrate Standby DB Instance in the Operation column.
  5. On the displayed page, select a target AZ and click Submit.
  6. After the migration is complete, you can view and manage the DB instance on the Instances page.

    • During the migration process, the DB instance status is Migrating standby DB instance. You can view the progress on the Task Center page. For details, see section Task Center.
    • In the upper right corner of the DB instance list, click to refresh the list. After the migration is complete, the DB instance status will become Available.
    • In the DB Information on the Basic Information page, you can view the AZ hosting the standby DB instance.

  • sync_binlog

    Default value: 1

    Function: Controls how often the MySQL server synchronizes binary logs to the disk. The default setting of 1 requires synchronization of the binary log to the disk at each transaction commit. If the value is set to 0, synchronization of the binary log to the disk is not controlled by the MySQL server but relies on the OS to flush the binary log to the disk. This setting provides the best performance, but in the event of a power failure or OS crash, all binary log information in binlog_cache is lost.

    Impact: If this parameter is not set to 1, data security is not guaranteed. If the system fails, data may be lost.

  • innodb_large_prefix

    Default value: OFF

    -

    Function: Specifies the maximum length of a single-column index in an InnoDB table.

    -

    This parameter is available only for MySQL 5.6.

    -
    -

    Impact: Changing this parameter value during DDL execution may cause primary/standby replication exceptions. Exercise caution when performing this operation.

    -
    • If you want to change this parameter value from OFF to ON, change it on read replicas first and then on the primary DB instance.
