CICS dumps in a sysplex

You can capture simultaneous dump data from multiple CICS® regions across a sysplex. This facility helps with problem determination in XCF/MRO environments where many CICS regions are running.

Capturing dump data in this way is useful in the following situations:

A task involves multiple CICS regions in a sysplex and one region issues a dump, typically in response to an error.
To fully diagnose and solve the problem, dump data from all CICS regions related to the region that issues the dump request is usually required. This dump data must be captured at the same time as the dump taken on the region that issues the dump.
A MVS™ console operator needs to capture, simultaneously, dump data from multiple CICS regions in the sysplex.

To collect dump data in this way, you need MVS/ESA 5.1, the z/OS® Workload Manager (WLM), and the XCF facility. The z/OS images in the sysplex must be connected through XCF. The CICS regions must be using MRO that is supported by the CICS TS 5.1 interregion communication program, DFHIRP.
