Recovering BlackBerry Enterprise Server components after the principal BlackBerry Configuration Database fails over to the 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. The BlackBerry Dispatcher automatically updates the Windows® registry information on the computers that host the BlackBerry Enterprise Server.

If you configure a new mirror BlackBerry Configuration Database, you must reconfigure the BlackBerry Dispatcher so that it can use the new mirror BlackBerry Configuration Database. If your organization's environment also includes BlackBerry Enterprise Server components that connect to the BlackBerry Configuration Database and that are installed on computers without a BlackBerry Dispatcher, you must reconfigure the BlackBerry Enterprise Server components so that they recognize the former mirror BlackBerry Configuration Database as the principal BlackBerry Configuration Database.

Recover BlackBerry Enterprise Server components after the principal BlackBerry Configuration Database fails over to the mirror BlackBerry Configuration Database

  1. On the computer that hosts the BlackBerry® Enterprise Server component or BlackBerry Dispatcher, on the Start menu, click Run.
  2. Type regedit.
  3. Click OK.
  4. Perform one of the following actions:
    • If you are running a 32-bit version of Windows®, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise Server\Database.
    • If you are running a 64-bit version of Windows, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Research In Motion\BlackBerry Enterprise Server\Database.
  5. Change the value for FailoverServerMachineName to the name of the database server that hosts the new mirror BlackBerry Configuration Database.
  6. On any computer that does not host a BlackBerry Dispatcher, change the DatabaseServerMachineName key to the name of the new principal BlackBerry Configuration Database.
