Part 8. Appendixes

Appendix A. System and default objects

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

The system objects are those WebSphere MQ objects needed to operate 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 23 lists the system and default queue objects.
Table 24 lists the system and default channel objects.
Table 25 lists the system and default namelist objects.
Table 26 lists the system and default process objects.
