Recursive 0C1 when using OMEGAMON during CICS startup

Question & Answer


Question

Why is CICS looping with an abend 0C1 during startup when OMEGAMON XE for CICS program KOCOME00 is in the DFHPLT? I had to remove KOCOME00 from the DFHPLT in order to bring up the CICS. I am using CICS Transaction Server for z/OS (CICS TS) V4.2.

Here is the messages that I see:

Answer

The recursive S0C1 has been fixed by OMEGAMON XE for CICS APAR OA46825:

 ABEND0C1 LOOP AFTER OMEGAMON MESSAGE OC0033: XMCR CICS IS USING 'RKC2XM01' DD NAME DURING CICS STARTUP.
  
 PTF List:

  Release 530   : UA76235 available 15/02/11 (F502 )

You should apply the PTF for the release of OMEGAMON you are running.
