Checking Whether the Source Database server_id Meets the Incremental Migration Requirements

MySQL

Table 1 Checking whether the source database server_id meets the incremental migration requirements

Check Item

Whether the source database server_id meets the incremental migration requirements

Description

Check whether the source database server_id meets the incremental migration requirements.

Failure Cause and Handling Suggestion

Failure cause: This item cannot be checked because the source database failed 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 server_id does not meet the incremental migration requirements.

Handling suggestion:

Run the following command to modify the server_id value:

set global server_id=n

The value n indicates the source database server_id. If the source database version is MySQL 5.6, the value n ranges from 2 to 4294967296. Otherwise, the value n ranges from 1 to 4294967296.

Failure cause: An internal error occurs.

Handling suggestion: Contact technical support.
