Error description

  • The IBM MQ haregtyp command is used to register (/r) and to
    unregister (/u) IBM MQ resources for use with Microsoft Cluster
    Server (MSCS).  When the haregtyp /r command succeeds, it
    prints a message similar to this:
    .
      The IBM WebSphere MQ resource and administration libraries
      have been successfully registered with MSCS.
    .
    .
    However, haregtyp /r issues the same message when it finds an
    existing IBM MQ resource registration, even if those resources
    are not valid (for example, if they point to an old MQ
    installation path which no longer exists).
    

Local fix

  • If the IBM MQ MSCS resources need to be redefined, you must
    first remove all queue managers from the MSCS cluster
    configuration, then stop and restart the Cluster service in
    Windows to free any references to IBM MQ DLLs.  Then you can
    unregister MQ from MSCS using 'haregtyp /u' and register it
    again using 'haregtyp /r' before adding your queue managers
    back to the MSCS configuration.

    PROBLEM DESCRIPTION:
    The error messages reported by haregtyp command were not useful
    to understand the cause of the failure in this scenario.

    additional user feedback if the registration fails.
