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.
