Module TIRMMDLL not found
The load module that abended was built with a release prior to Gen 8.5. It must run with the Gen 8.5 or 8.6 runtime library CEHBPLD1. The module TIRMMDLL is not in the runtime library CEHBPLD1 for Gen 8.0 or LOAD for releases prior to Gen 8.0.
Module TIRMMDLL is new beginning in Gen 8.5. It is located in the Gen 8.5 CEHBPLD1. The resolution is to remove the older runtime Gen libraries in the CICS region DFHRPL and add the Gen 8.5 or 8.6 CEHBPLD1.
A work-around is to rebuild the abending load module with the older encyclopedia release that matches the runtime in CICS region DFHRPL.
