WebSphere MQ MSCS support utility programs

 

WebSphere MQ support for MSCS includes the following utility programs that we can run at a command prompt:

Register/unregister the resource type

haregtyp.exe

After you unregister the WebSphere MQ MSCS resource type we can no longer create any resources of that type. MSCS does not let you unregister a resource type if you still have instances of that type within the cluster:

  1. Using the MSCS Cluster Administrator, stop any queue managers that are running under MSCS control, by taking them offline as described in Taking a queue manager offline from MSCS.

  2. Using the MSCS Cluster Administrator, delete the resource instances.

  3. At a command prompt, unregister the resource type by entering the following command: 
    haregtyp /u

If you want to register the type (or re-register it at a later time), enter the following command at a command prompt: 

haregtyp /r
After successfully registering the MSCS libraries, reboot the system if you have not done so since installing WebSphere MQ.

Move a queue manager to MSCS storage

hamvmqm.exe

See Moving a queue manager to MSCS storage.

Delete a queue manager from a node

hadltmqm.exe

Consider the case where you have had a queue manager in your cluster, it has been moved from one node to another, and now you want to destroy it. Use the WebSphere MQ Explorer to delete it on the node where it currently is. The registry entries for it still exist on the other computer. To delete these, enter the following command at a prompt on that computer: 

hadltmqm /m qmname
where qmname is the name of the queue manager to remove.

Check and save setup details

amqmsysn.exe

This utility presents a dialog showing full details of your WebSphere MQ MSCS Support setup, such as might be requested if you call IBM support. There is an option to save the details to a file.
