Managing CAS-to-CAS communication

The figure in Managing-cross-system-communication shows how BMC AMI Ops products communicate with each other between system images. Typically, a single CAS serves as a node that transfers information collected from all PASs running on a system image. XCF communication is established automatically between CASs running in the same sysplex and in the same XCF group. If you do not want two sets of CASs within a sysplex to communicate through XCF, you can change the default XCF group to a different value by using:

• DFLTGRP= parameter on the CAS startup JCL
• CASDEF administrative view

For example, if you have a production set and a test set, the test CASs can use a default group name of TESTCAS while the production CASs use the default group name BBGROUP.

VTAM communication is established between CASs that are running on separate images outside of a sysplex environment. Optionally, you can establish TCP/IP communication by specifying a port number and IP address on the CAS definition.

The following table lists common tasks and the associated commands for controlling cross-system communication links between a local CAS and a remote CAS. Each task includes a page reference to more information about completing the task.
