Correlating by network unit-of-work ID

The network unit-of-work ID (owner: DFHTASK, field IDs: 097 and 098) can be used to correlate the performance class data records from a single or multiple CICS® systems.

This name is assigned at transaction attach time using either a netname derived from the terminal (when the task is attached to a local VTAM® terminal), or the netname passed as part of an IRC (MRO) or ISC (APPC) attach header combined with a STCK-derived token created by the originating system, or the network unit-of-work ID passed as part of an IRC (MRO) or ISC (APPC) attach function management header (FMH).

Workload Activity report

The CICS PA Workload Activity report also correlates the performance records by network unit-of-work ID and can be used to understand the type and flow of a CICS transaction across CICS systems and its relationship with the MVS™ Workload Manager (WLM).

For more information, see Workload Activity report.

Cross-System Work report and extract

The CICS PA Cross-System Work report correlates performance class data from a single or multiple CICS systems, as long as the performance data is part of the same network unit-of-work.

The Cross-System Work report is particularly useful in understanding the type and flow of a CICS transaction across CICS systems, including:
