Attributes for the queue manager
Some queue manager attributes are fixed for particular implementations; 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 MQOT_Q_MGR 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 descriptive names used with the MQINQ call; the names are the same as for the PCF commands. When MQSC commands are used to define, alter, or display attributes, alternative short names are used; see MQSC commands for more information.| Attribute | Description |
