System and default objects

System and default objects

Lists the system and default objects created by the crtmqm command.
When creating 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 creating 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. Note: There are two other default objects not included in the tables: the queue manager object and the object catalogue. These are objects in the sense that they are logged and recoverable.
