I am happy to announce on behalf of the CA Mainframe Application Tuner development team that for CA MAT V12 new enhancement is available via our maintenance stream. To obtain CICS CALLER ID / CALLER STACK enhancement use following links: #SO06630 and #SO06631




Using CICS exits CA MAT collects detailed information on transactions and sequence of within program calls including counts and elapsed times see Fig 1 and 2. Feature offers more detailed and accurate performance tuning identification possibilities for CICS oriented workloads. This implementation goes beyond typical sample collection mechanism allowing trace-back of all programs managed by CICS region for measured transaction.
