System and default objects

System and default objects

When you create a queue manager using the CRTMQM command, the system objects and the default objects are created automatically.

The system objects are those WebSphere MQ objects required for the operation of a queue manager or channel.
The default objects define all the attributes of an object. When you create an object, such as a local queue, any attributes that you do not specify explicitly are inherited from the default object.

The following tables list the system and default objects created by CRTMQM:

Table 15 lists the system and default queue objects.
Table 16 lists the system and default channel objects.
Table 17 gives the system and default authentication information object.
Table 18 gives the system and default listener object.
Table 19 gives the system and default namelist object.
Table 20 gives the system and default process object.
Table 21 gives the system and default service object.
