Attributes for the queue manager on IBM i

A summary of queue manager attributes.

Some queue manager attributes are fixed for particular implementations, while others can be changed by using the MQSC command ALTER QMGR. The attributes can also be displayed by using the command DISPLAY QMGR. Most queue manager attributes can be inquired by opening a special OTQM object, and using the MQINQ call with the handle returned.

The following table summarizes the attributes that are specific to the queue manager. The attributes are described in alphabetical order.

Note: The names of the attributes shown in this section are the names used with the MQINQ and MQSET calls. When MQSC commands are used to define, alter, or display attributes, alternative short names are used; see Script (MQSC) Commands for more information.
