IT23413: Running crtmqm -md against an existing queue manager removes thequeue manager's data directory

APAR status

• Closed as program error.

Error description

• Running "crtmqm -md <directory> <qmName>" against a queue
  manager which already exists removes the queue manager's data
  directory.
  

Local fix

• Do not run crtmqm -md against an existing queue manager
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of MQ v8 and v9, who incorrectly supply
  the name of an existing queue manager and the -md flag to the
  crtmqm command.
  
  Furthermore, this issue is only observed if the queue manager
  was originally created using the default data directory.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A logic error within the crtmqm code path taken when an
  alternate data directory was specified with the -md option
  resulted in destructive file operations being performed before
  the check that the queue manager did not exist.
  
  In the case where all of the conditions described in the users
  affected section were true, this resulted in the removal of the
  existing queue manager's data directory.
  

Problem conclusion

• This issue in the crtmqm command has been addressed so that the
  command returns with the following error in this scenario:
  
  AMQ8110: WebSphere MQ queue manager already exists.
  
  The existing queue manager's data directory remains in place.
