How CAIENF/CICS SPAWN Checks for Intercept Modules

The installation of the CAIENF/CICS SPAWN intercept in a CICS region requires the CAS9SPxx module where xx identifies the CICS release. The modules are distributed in the CAW0LOAD data set.

CAIENF/CICS SPAWN checks for the modules in the following sequence. Remember this if you want to override an intercept module with another intercept module (when testing maintenance). For the intercepts to install, ensure that the required modules are in one of the indicated locations.

1. CAIENF/CICS SPAWN searches for the module in the library that a CENFLIB DD statement in the CICS startup JCL member specifies. If the statement exists and the module is found, it loads the module into the private address space of the CICS region.
2. If the CENFLIB DD statement does not exist or the module is not found, CAIENF/CICS SPAWN searches for the module in the STEPLIB of the CICS startup JCL member. If the module is found, it loads the module into the private address space of the CICS region.
3. If the module is not found in the STEPLIB, CAIENF/CICS SPAWN checks the CSA. You can load modules into CSA by using the CAIENF/CICS SPAWN CICSPAWN control option.
