Correlating by transaction group ID

The transaction group ID (owner: DFHTASK, field ID: 082) is assigned at transaction attach time and can be used to correlate the performance class records for the transactions that CICSĀ® runs for the same incoming work request (for example, the CWXN and CWBA transactions for CICS Web support requests).

This transaction group ID relationship is particularly useful when applied to the requests that originate through the CICS Web support (CWS), CICS IIOP, ECI over TCP/IP, or the 3270 bridge interface. The transaction origin can be determined from the transaction origin type in byte 4 of the transaction flags field (owner: DFHTASK, field ID: 164).

Transaction Group report

The CICS PA Transaction Group report correlates the performance class data records from a single system, as long as the transactions are part of the same incoming work request (they have the same transaction group ID).

The Transaction Group report is particularly useful in understanding the relationship and flow of transactions that originate through the CICS Web support (CWS), IP interconnectivity connections (IPIC), External Call Interface (ECI) over TCP/IP, or the 3270 bridge interface.
