System and default objects

Lists the system and default objects created by the crtmqm command.

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 IBM 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 we 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 topic objects.
  • Table 3 lists the system and default channel objects.
  • Table 4 lists the system and default authentication information objects.
  • Table 5 lists the system and default listener objects.
  • Table 6 lists the system and default namelist objects.
  • Table 7 lists the system and default process objects.
  • Table 8 lists the system and default service objects.
