About this task
All planned full and partial DR switchovers require that the Omnichannel DB servers in both locations are functioning properly and that data is mirrored between them. After a planned switchover, mirroring shall initiate from the DR site (DC2) to the original primary site (DC1).
In the event of unplanned switchovers due to Omnichannel failures, you must reinstate the failed servers first, and then reinstate the mirroring. Refer to Clean up Mirror setup on DC1 and DC2 for procedure on reinstating a failed Omnichannel server before proceeding with the switchover.
It is important to verify that data from the primary Omnichannel database is actually mirrored across a data link to the DR database before switchback. To do this, log on to the Omnichannel Database server in the DR site and verify the mirroring status from the primary to DR site. This is a necessary step to ensure operational readiness before switchback.
Use the following steps to verify the DB mirroring status using the Oceana Data Management (ODM) tool:
