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.
