Recovering after the User Name Server's queue manager fails

Try to get to the root of the problem first, using the diagnosis techniques described throughout the Troubleshooting and support section of the information center. If your problem cannot be resolved using these techniques, contact your IBM Support Center. Use the procedure in this section only as a last resort.

If the failed queue manager was shared between a broker, User Name Server, and Configuration Manager, re-create all three components, because each component creates different queues. For information on how to recover a shared queue manager, see Recovering after a shared queue manager fails.

If the User Name Server's queue manager fails and cannot be corrected using problem determination, or by the IBM Support Center, perform the following sequence of operations to re-create the queue manager:

  1. Ensure that no workbench users are deploying to brokers. You must wait until any such actions have completed.
  2. Stop the User Name Server using the mqsistop command.
  3. Delete the User Name Server using the mqsideleteusernameserver command, with the -q parameter to remove the queue manager.
  4. Re-create the User Name Server using the mqsicreateusernameserver command. The mqsicreateusernameserver command creates the queue manager and default queues automatically.
  5. Start the User Name Server using the mqsistart command.
  6. Redeploy the domain configuration.
