Working with queue managers

Examples of MQSC commands that you can use to display or alter queue manager attributes.

Displaying queue manager attributes

To display the attributes of the queue manager specified on the runmqsc command, use the following MQSC command:


DISPLAY QMGR

Typical output from this command is shown in Figure 1

   TREELIFE(1800)                          TRIGINT(999999999)

Note: SYNCPT is a read only queue manager attribute.

The ALL parameter is the default on the DISPLAY QMGR command. It displays all the queue manager attributes. In particular, the output tells you the default queue manager name, the dead-letter queue name, and the command queue name.

You can confirm that these queues exist by entering the command:


DISPLAY QUEUE (SYSTEM.*)

This displays a list of queues that match the stem SYSTEM.*. The parentheses are required.

Altering queue manager attributes

To alter the attributes of the queue manager specified on the runmqsc command, use the MQSC command ALTER QMGR, specifying the attributes and values that you want to change. For example, use the following commands to alter the attributes of jupiter.queue.manager:


runmqsc jupiter.queue.manager
ALTER QMGR DEADQ (ANOTHERDLQ) INHIBTEV (ENABLED)

The ALTER QMGR command changes the dead-letter queue used, and enables inhibit events.
