Local fix

• Restoring the deleted queue file from backup is likely to
  resolve the queue manager startup problem.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users deleting queue files associated with dynamic queues
  Platforms affected:
  MultiPlatform
  ****************************************************************
  PROBLEM DESCRIPTION:
  This problem occurred because the queue manager detected a
  missing object associated with a dynamic queue, but the queue
  manager did not handle this error correctly, particularly
  releasing the lock associated with the dynamic queue. This
  resulted in failure in the queue manager startup.
  

Problem conclusion

• The MQ queue manager code has been modified to correctly handle
  the object damage error because of missing queue files
  associated with dynamic queues.
