System and default objects for IBM i

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 IBM® 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 1 lists the system and default queue objects.
  • Table 2 lists the system and default channel objects.
  • Table 3 gives the system and default authentication information objects.
  • Table 4 gives the system and default listener object.
  • Table 5 gives the system and default namelist object.
  • Table 6 gives the system and default process object.
  • Table 7 gives the system and default service object.
