CAIENF/CICS Requirements
CAIENF/CICS has the following installation requirements:
- CAIENF/CICS works with all releases of CICS TS generally supported by IBM.
- CAIENF/CICS has a subtask that runs within the CAIENF address space. The primary function of the subtask is to monitor all CICS regions and to handle operator commands. A procedure containing the CAIENF started task JCL must be defined in any PROCLIB data set. The sample that is provided on the CA Common Services for z/OS distribution media can be tailored to your data center requirements.
- CAIENF/CICS supports various control options that can be tailored to meet the individual data center requirements.
- Process the CAS9DCM2 DCM module by CAIENF with a DCM(CAS9DCM2) CAIENF parameter in the ENFPARMs file. No database is required but the DCM must be installed.
- The primary function of the CAIENF/CICS Interface is to provide one common service for handling CICS release dependencies. This alleviates the effects of new CICS releases on CA CICS solutions.
- The CAIENF/CICS Interface consists of a different set of load modules for each CICS release. These modules are loaded into CSA when CAIENF is started. Optionally, the appropriate load module can be loaded into the CICS Private Area. Each module uses approximately 40 KB of CSA or CICS Private Area, depending on where it is loaded.
- When a CICS Region is started, CAIENF/CICS checks for the existence of a DDNAME of CENFLIB. If this DDNAME is defined, CAIENF/CICS loads the appropriate modules into the CICS Private Area. If the DDNAME of CENFLIB is not defined, CAIENF/CICS tries to load the modules from STEPLIB. If the modules are found in STEPLIB, they are loaded into the CICS Private Area. Lastly, CAIENF/CICS attempts to find the modules in CSA.
- To use this feature to apply maintenance on the global CAIENF/CICS modules, enter the ENF REFRESH(CAS9Cxx) control option, where xx is the release of CICS.
The following lists the minimum storage requirements for each CAIENF/CICS distribution library. This list does not necessarily represent the actual distribution library allocation that is provided during the installation.
