CAIENF/CICS SPAWN Requirements

CAIENF/CICS SPAWN has the following installation requirements:

• CAIENF/CICS SPAWN works with all releases of CICS TS generally supported by IBM.
• CAIENF/CICS SPAWN supports various control options that can be tailored to meet the individual data center requirements.
• CAICCI is required software. Install CAICCI before the installation of CAIENF/CICS SPAWN.

Note: For more information about CAIENF/CICS SPAWN, see the Administration Guide.

The primary function of CAIENF/CICS SPAWN is to let CA solutions start CICS units of work from outside the CICS region. The facility provides a layer that isolates the application software from the CICS release. CAICCI is the proprietary communications vehicle that enables this facility.

When a CICS region is started, CAIENF/CICS SPAWN checks for the existence of a DDNAME of CENFLIB. If this DDNAME is defined, CAIENF/CICS SPAWN loads the appropriate modules into the CICS Private Area. If the DDNAME of CENFLIB is not defined, CAIENF/CICS SPAWN 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 SPAWN attempts to find the modules in CSA.

The following lists the minimum storage requirements for each CAIENF/CICS SPAWN distribution library. This list does not necessarily represent the actual distribution library allocation that is provided during the installation.
