Configuring BlackBerry Configuration Database high availability

To configure the BlackBerry Enterprise Server instances and components, you delete the pull subscription from the replicated database server, run a SQL query to update the numbering of the identity values in the replicated BlackBerry Configuration Database, and run the BlackBerry Enterprise Server setup application to permit each BlackBerry Enterprise Server instance and component to connect to the replicated BlackBerry Configuration Database.

Return to the BlackBerry Configuration Database when you configured transactional replication

When the BlackBerry Configuration Database becomes available again after it has stopped responding, you can update the BlackBerry Enterprise Server and BlackBerry Enterprise Server components so that they use the BlackBerry Configuration Database instead of the replicated BlackBerry Configuration Database.

1.Back up the replicated BlackBerry Configuration Database.

2.To avoid data corruption, prevent each BlackBerry Enterprise Server instance from connecting to the replicated BlackBerry Configuration Database.

3.On the database server that hosts the BlackBerry Configuration Database, replace the BlackBerry Configuration Database with a restored version of the replicated BlackBerry Configuration Database.

4.Run the setup application to permit each BlackBerry Enterprise Server instance and BlackBerry Enterprise Server component to connect to the BlackBerry Configuration Database.

Configuring a new mirror BlackBerry Configuration Database

If the principal BlackBerry Configuration Database stops responding and the BlackBerry Enterprise Server fails over automatically to the mirror BlackBerry Configuration Database, the mirror BlackBerry Configuration Database becomes the new principal BlackBerry Configuration Database.

If you configure a new mirror BlackBerry Configuration Database, you must resend the database mirroring parameters to the BlackBerry Enterprise Server components so that they can use the new mirror BlackBerry Configuration Database.
