Making an existing queue manager the default

When you create a default queue manager, its name is inserted in the Name attribute of the DefaultQueueManager stanza in the WebSphere MQ configuration file (mqs.ini). The stanza and its contents are automatically created if they do not exist. 

[mqm@middlewaretech mqm]$ pwd

/var/mqm

[mqm@middlewaretech mqm]$ vi mqs.ini

To make an existing queue manager the default, change the queue manager name on the Name attribute to the name of the new default queue manager. You can do this manually, using a text editor. 

If you do not have a default queue manager on the node, and you want to make an existing queue manager the default, create the DefaultQueueManager stanza with the required name yourself. 

If you accidentally make another queue manager the default and want to revert to the original default queue manager, edit the DefaultQueueManager stanza in mqs.ini, replacing the unwanted default queue manager with that of the one you want.

Important configuration files

  When you install the product, the WebSphere MQ configuration file (mqs.ini) is created. It contains a list of queue managers that is updated each time you create or delete a queue manager. There is one mqs.ini file per node.

When you create a new queue manager, a new queue manager configuration file (qm.ini) is automatically created. This contains configuration parameters for the queue manager.After creating a queue manager, we recommend that you back up your configuration files.
