DFHSR0601 during startup after upgrading to CICS TS 5.3 when using PLT

Question & Answer

Question

Why am I receiving message DFHSR0601 for system task III during startup after upgrading to CICS Transaction Server for z/OS (CICS TS) 5.3? I had the CICS region up and was able to logon until I included programs in the the program list table (PLT).

The syslog shows the following messages,

 DFHSI1519I The interregion communication session was

Answer

CICS TS 5.3 was being used with Debug Tool for z/OS 9.1. However, the CICS TS 5.3 Detailed System Requirements (DSR) indicate that the minimum prerequisite is Debug Tool for z/OS 13.1 and Note 4 says "PTF (UI33649) for APAR PI51340 is required". To see this requirement in the CICS DSR:

Click on Supported Software
Click on Development Tools
Scroll down to "Debug Tool for z/OS"

If you are running a release of CICS other than CICS TS 5.3, see Detailed System Requirements for CICS Transaction Server for links to the DSRs for other releases.

To determine if this is your problem, you can look at the SR0601 dump to see if the failing instruction is in a Debug Tool module. First, enter VERBX DFHPD700 'KE' (where 700 is for release 5.3 of CICS TS 5.3) to look at the KE domain. In this case, the running task in error is tran ID CSSY and "The failing instruction is in EQA10MVS" which is a Debug Tool module:

 001A 0E295000 ***Running** 0D3A3800 III CSSY  0D262800 0D143200 *YES*

     The failing instruction is in EQA10MVS date 2010/03/10 + xE4
     R15:00000000_00000000 was bad. Thus abend0c1 was occurred..
     R15 is from R12:000579C8+x2B4

Next, you could enter option 1 from the IPCS primary option menu to Browse storage in the dump data set starting at the PSW address. Scroll backwards until you find the eyecatcher of the failing module.
