WebSphere MQ objects

 

The WebSphere MQ objects are:

  • Queue managers
  • Queue-sharing groups (WebSphere MQ for z/OS only), although these are not strictly objects.
  • Queues
  • Namelists
  • Process definitions
  • AUTHINFO objects
  • Channels
  • Storage classes (WebSphere MQ for z/OS only)

Queue managers define the properties (known as attributes) of these objects. The values of these attributes affect the way in which these objects are processed by WebSphere MQ. From your applications, you use the Message Queue Interface (MQI) to control these objects. Objects are identified by an object descriptor (MQOD) when addressed from a program.

When you use WebSphere MQ commands to define, alter, or delete objects, for example, the queue manager checks that you have the required level of authority to perform these operations. Similarly, when an application uses the MQOPEN call to open an object, the queue manager checks that the application has the required level of authority before it allows access to that object. The checks are made on the name of the object being opened.
