DCS XCF setup

What is XCF Communications Manager (XCFM)?

The XCF Communications Manager manages communications between different instances of BMC ThruPut Manager using the cross-system coupling facility (XCF). XCFM executes as a subtask in the BMC ThruPut Manager Support Services (TMSS) address space.

Using XCFM provides improvements to the way in which multiple instances of BMC ThruPut Manager communicate. This means that even if your installation uses only a single JESPlex, it is a good idea to use XCFM.

For installations using MIM instead of GRS, contact BMC Support.

Dataset Contention Services and XCF

Dataset Contention Services (DCS) requires cross-systems communication in a multisystem environment. Data set holders might not be on the same system as the job needing the data set. When a job that is holding a data set terminates, notification might be required on another system on a different node. As well, some DCS operator commands must query all systems sharing the relevant DASD.
