Downloading Switchover/Failover Logs of a GaussDB Instance

You can download switchover/failover logs of a GaussDB instance. If switchover/failover log collection is enabled for an instance whose Failover Priority is Availability, GaussDB can collect Xlogs that cannot be replayed on the standby node in time when a switchover or failover occurs and convert the Xlogs into a SQL file. You can download the SQL file and run SQL statements to replay the data in the SQL file as required.

Precautions

  • CNs and DNs of the instance are normal.
  • The IaaS network is normal.
  • Switchover/Failover logs are available only for distributed instances whose Failover Priority is Availability.
