DFHDS0002 0198 in DFHDSMT after upgrading to CICS TS 5.1 when using ASG-TMON

Question & Answer


Question

Why is my region getting message DFHDS0002 with severe CODE X'0198' in DFHDSMT then crashing with End of Memory (EOM) after upgrading from CICS Transaction Server for z/OS (CICS TS) V4.1 to V5.1? I am using ASG TMON.

This is the complete message:
DFHDS0002 A SEVERE ERROR (CODE X'0198') HAS OCCURRED IN MODULE DFHDSMT

Looking at the CICS Internal Trace I see:

 0198 DSMT  *EXC* - DSMT_SNAP_FAILURE - FUNCTION(SNAPSHOT_MVSTCBS)

The exception occurs due to being Short on Storage (SOS) above the line. It appears that Subpool 132 (Key 8) storage is using up most of the Storage.

 AF8240    132    8        A000 5D2EA000 5D2F4000

When I look at Subpool 132, I see the following pattern of x'1000' pieces of storage.

 Starting at: DQE:  Addr 2156D000 Size     1000

 Ending at: DQE:  Addr 7E3DD000 Size     1000

All of the pieces of storage in this area had the following Eyecatcher Data.

 TMCE040 QCPOOL TMON975 TMCESCHBTMON975

Answer

Support for ASG-TMON for CICS TS for z/OS was contacted and ASG recommends that you apply TMON fix ++PTF(TH03807) /* -LTCE400 /. Contact ASG Support if you need additional assistance.
