Checking Whether the ExpireLogsDays Value Is 0

MySQL Synchronization and Disaster Recovery

**Table 1** Checking whether the expirelogsdays value is 0
Check Item	Whether the expirelogsdays value is 0
Description	If the expire_logs_days value of the source database is set to 0, the migration may fail.
Failure Cause and Handling Suggestion	Failure cause: If expire_logs_days is set to 0 in the source database, operations such as startup and flush logs will trigger binlog clearance and result in a migration failure. Handling suggestion: Set the binlog storage duration by running the following command on the client: set global expire_logs_days=value (value indicates an integer greater than 0.)
