XCF Transport Class Simplification functionality was implemented in z/OS 2.4,
with an objective to eliminate the need for manually managed transport classes
at most sites. This new functionality has been generally well-received and been
effective in accomplishing its objective of minimizing the XCF customization
activity required by systems programmers. However, to get the most value from
this new capability, installations should ensure that their XCF signaling
resources are consistent with XCF's new approach. Some site-dependent
configuration activities still remain, including determining appropriate MAXMSG
specifications for buffers and the appropriate number of signaling paths. To
assist with this analysis, z/OS 2.4 introduced XCF path usage metrics in the RMF
74.2 records. In this session Frank and Todd will: "¢ Explain why you might need
to make changes to your current setup "¢ Explore these new XCF path usage metrics
"¢ Explain the XCF concepts behind the metrics "¢ Discuss ways to interpret the
metrics to optimize your XCF configuration Attendees of this session can expect
to come away with a better understanding of how XCF operates in general, tips
about how to optimize their environment for the new paradigm, and information
about what can be learned from the new Path Usage metrics.
