Description:

Following an upgrade to Common Services v14.0 or r14.1, ENF can fail to initialize, issue a U0203 abend and create an SVC dump with the title CA-ENF EVT@DCMC/DCMC Corruption.

Messages similar to the following are issued:

 IEA794I SVC DUMP HAS CAPTURED: 821
 DUMPID=002 REQUESTED BY JOB (ENF)
 DUMP TITLE=CA-ENF EVT@DCMC/DCMC Corruption
 CAS9203E - CA-ENF Initialization error - terminati
 IEF450I ENF ENF - ABEND=S000 U0203 REASON=00000010

Solution:

This failure is likely due to a mixed release environment and the current v14.0 or r14.1 ENF modules are not being executed.

Review your linklist and ensure that there is not an older load library containing any Common Services modules concatenated in front of the most current Common Services libraries CAW0LINK and/or CAW0LOAD. Either remove the older library from linklist (if possible) and Steplib to the appropriate CAW0LOAD in your ENF proc, or concatenate the appropriate CAW0LOAD library ahead of that older load library that still may need to exist in the linklist.
