• SymDump for CICS

Issue/Introduction

We IPL'd the production lpar yesterday.
We put the Intertest and Symdump release 11 datasets into the APF authorization and LNKLST.
Also, initialized v11 datasets in CARIMPRM.

The CICS started tasks, however, still reference the v10 datasets.

Some messages from CICS output:

+CASD6049 SYMDUMP V10.0000 COLD ASM 12/13/2017 15.45

DFHDU0205  CICSPA1  A SYSTEM DUMP FOR DUMPCODE: AP0001  , WAS SUPPRESSED BY THE DUMP TABLE OPTION FOR THIS DUMPCODE  

Why is this system dump being suppressed?

Environment

Z/OS 

CICS 

Cause

Symdump CICS only captures Transaction dumps and will not capture System dumps which is what the AP0001 is.

Resolution

Symdump CICS only captures Transaction dumps and will not capture System dumps which is what the AP0001 is.

Symdump CICS does have the ability to suppress AP0001 dumps on the SYMI transation configuration screen parameter

Suppress AP0001 dumps: Y (Y,N)

Symdump CICS gets invoked at the CICS global user exit XDUREQ. You can use the transaction IGLU to see the CICS global user exits. My example IGLU below is for CTS 5.4 program IN71 EXIT.
EXIT NAME PROGRAM ENTRY NAME ADDRESS STATUS

XDUREQ IN71EXIT IN71EXIT 800AA000 STARTED

The format of the Suppression message DFHDU0205 the case was opened with tells me CICS suppressed the AP0001 dump

DFHDU0205 CICSPA1 A SYSTEM DUMP FOR DUMPCODE: AP0001 , WAS SUPPRESSED BY THE DUMP TABLE OPTION FOR THIS DUMPCODE

If Symdump CICS suppressed the AP0001 dump you would see the suppression was done by the XDUREQ  global user exit program IN71EXIT with the message format below.
