We are upgrading a CICS region from 4.2 to 5.3. When we start the region, ACF2 for CICS Phase 0 initialization completes, but Phase 1 & 2 do not. I've reviewed our setup and cannot find anything obviously wrong. At the same time, however, our sandbox CICS 5.3 region works fine with the same setup. Why would all phases complete successfully in one region and not another?
Although the CICS region JCL was identical in the two environments, the inconsistent results were due to a difference in the ENF parms used to establish the security protection of the CICS region(s).
Using the Common Services ENF/CICS component to protect one or more CICS region(s) with either CA ACF2 or CA Top Secret.
As stated above, the ENF parms can be set to automatically install the intercepts in one of two ways:
The ENF MODE(CICS,ON), the CICSREL(nn...) parms, and the supported CICS releases used in the CICSREL parm are detailed in
The usage of the two parms is discussed in
