I have applied CARS2504 maintenance, containing Dynamic System Table (DST) updates, successfully to several test environments, but in one MUF the DDUPDATE immediately fails with:
SYSTEM COMPLETION CODE=0C4 REASON CODE=00000004
NO ACTIVE MODULE FOUND
NAME=UNKNOWN
Component: Datacom/DB
After reviewing the dump produced by the S0C4, we could see that IPC module VTPM9803 used in the JCL was an old version.
Change the JCL to use the module from IPC 15.1 in CAVQLOAD 15.1.
NOTE: The VTPM9803 module was supposed to be included in the first LOAD library in the STEPLIB, but for some reason when this MUF was built the IPC modules were not included. Problem Solved after changing the LOAD library to include IPC 15.1 modules.
