Issue/Introduction

After upgrading CICS, the region fails at startup with:

+DFHXS1105 CICSTRNT Resource profiles for class TCICSTRN have been built.       
+DFHKE1800 CICSTRNT ABNORMAL TERMINATION OF CICS IS COMPLETE.                   
BPXP018I THREAD 28B5380000000000, IN PROCESS 33555063, ENDED  914               
WITHOUT BEING UNDUBBED WITH COMPLETION CODE 00000708                            
, AND REASON CODE 00000000.                                                     
IEF450I CICSTRNT DFHSIP - ABEND=S000 U1800 REASON=00000000  915            

It was discovered that the ENF parameter CICSREL was not properly set for the new CICS release. After updating the CICSREL parameter, does this take an IPL to correct or is there a way to dynamically change CICSREL in ENF?

 

 

 

 

    

Environment

Component : CA Top Secret for z/OS

Resolution

An IPL is not needed to change the CICSREL parameter in ENF. You can recycle ENF to pick up the new CICSREL, then recycle the CICS region.
