MQ subsystem discovery

The MQ subsystem book contains the following:
  • MQ Subsystem details and relationships
  • Cluster details and relationships
  • Channel details and relationships:
    • Sender Channel
    • Receiver Channel
    • Server Channel
    • Requester Channel
    • Cluster Sender Channel
    • Cluster Receiver Channel
    • Client Connection Channel
    • Server Connection Channel
  • Queue details and relationships:
    • Local Queue
    • Remote Queue
    • Alias Queue
    • Model Queue

To avoid a potentially high volume of instances being populated unnecessarily and impacting CCMDB performance, by default, MQ Queues are not populated.

The following diagram shows the classes and relationships that are populated in the MQ books. The boxes that are clear are not populated.

MQ Subsystem details and relationships

See Appendix C. z/OS DLA data model class types represented in CDM for details on what attributes and relationships are discovered for these classes.

Note:
  • The z/OS® instance is a stub. This instance contains enough information to identify the instance and is populated for MQ subsystem naming rules. The ZOSBASE book contains full details about z/OS.
  • The DLA uses an MQ API for MQ discovery. If the MQ load module datasets are not in the LINKLST, they must be added to the DLA's STEPLIB DD concatenation. For more details, refer to the Installation and Customization section.
