Checking Whether the Source Database Binlog Is Row-Based

Whether the source database binlog is row-based

Check whether the source database binlog is row-based.

Failure cause: This item cannot be checked because the source database fails to be connected.

Handling suggestion: Check whether the source database is connected.

Failure cause: Insufficient user permissions

Handling suggestion: Check whether the database user permissions meet the migration requirements.

Failure cause: The source database binlog is not row-based.

Handling suggestion:

• If the source database is an on-premises database, perform the following operations to change the binlog format of the source database:

  Method 1: You can modify the my.cnf or my.ini configuration file and restart the database.

  binlog_format=row

  Method 2: Stop all service connections.

  set global binlog_format='ROW'

  Modify the my.cnf or my.ini configuration file.

  binlog_format=row

  In the ROW format, the log growth rate increases, which may occupy more disk space.

  NOTE:
• If the source database is an RDS DB instance on the cloud, change the binlog_format value of the source database to ROW. After the change, restart the database for the change to take effect.
  NOTE:

Failure cause: An internal error occurs.

Handling suggestion: Contact technical support.
