How to perform database replication failover.

If you need to shut down the Primary server for maintenance, you can perform a failover. The failover process promotes a selected Standby server to the Primary role, and converts the current Primary server to a Standby role. During the failover process, the database retains all committed transactions and becomes available in a stable, known, good state.
Note:
  • You must be an Address Manager administrator to perform database replication failover.
  • When you perform a database failover, Address Manager restarts the Primary and Standby servers. All servers will be unavailable for a few minutes while they restart.
Use the Failover command when you need to perform maintenance work on the Primary server and want another server to temporarily maintain the Primary database. You can perform the failover from the Primary server or from a Standby server.
Note: To perform a failover, the Primary database must be online. If the Primary server is offline, the Primary database is not available, so you cannot log in to the Address Manager web interface on the Standby servers.

If the Primary server is not online, use the reset replication Administration Console command on the Standby server or servers. For more information, refer to Resetting database replication.
