IMS Common Queue Server Subtask Setup
The IMS Common Queue Server subtask (IMSCQS) is the interface between the z/OS Common Queue Server (CQS) and CA SYSVIEW.
The IMSCQS task:
- Issues CQS queries to obtain the information on the following:
- IMS shared message queues
- Structures that support a shared messaging environment
- Processes requests for shared message queue data from the CA SYSVIEW IMSQSTAT, IMSQTRAN and IMSTRANS, as well as the IMS Data Collector task.
- Automatically discovers IMS subsystems in a shared messaging environment and connects to the queue structures defined to the IMS.
- Queries the CQS based on the queue sharing group assigned to the current target IMS subsystem when the display command is issued. The target IMS subsystem can be set by selecting an IMS subsystem on the IMSLIST display, issuing the IMS SYSVIEW command or setting the IMSTGTDEF variable.
To use the IMSCQS, you need to have the following configured and implemented:
- CA SYSVIEW Option for IMS
- IMS Common Services Layer
- IMS Common Queue Server
Note: There is no need to start the IMSCQS task because it starts automatically when the SYSVIEW main task starts. The task may also be started or stopped from the ASADMIN display. If no IMS subsystems are participating in IMS queue sharing groups, then removing the task from the SYSVIEW PARMLIB member will prevent it from starting. For more information on configuring IMS Shared Message Queues, see the IBM documentation.
