Occasionally, the CA IDMS CV constantly fills the log area (DDLDCLOG) and starts submitting many PLOG jobs to print and archive the log.
Release : 19.0
Component : CA IDMS/DB
An ADS program check abend (data exception) caused an extremely large task snap.
The majority of the PRINT LOG output contents are the SYSTRACE entries after the photo and before the actual snap.
As of IDMS 18.0 and later the size of the SYSTRACE table in memory is much larger than in prior releases (defaults to 4 MB now).
For debugging user program abends the SYSTRACE entries in each task snap are not useful and will fill the log really fast.
Turn off the SYSTRACE for task snaps. In the SYSGEN SYSTEM statement code:
SNAP TASK IS ON
SNAP TASK PHOTO IS ON
SNAP TASK TRACE IS OFF
You can also turn off the trace entries in task snaps dynamically with the command:
DCMT V SNAP TASK TRACE OFF
