Use the ISM_ERROR_MSG_BLOCKS parameter in CQMPARMS to control the ISM messaging behavior of your Query Monitor Subsystem.
- The number of ISM error message blocks (n) that are allocated when Db2 Query
Monitor initializes. If this value is too low, duplicate ISM error
messages might be issued for the same space and reason instead of incrementing the occurrence count.
ISM error message blocks are used by the task that issues storage constraint messages to:
- Consolidate similar storage constraint events to eliminate duplicate messaging for the same condition, and
- Track storage constraint events so that the Storage Constraint Relieved situation can be detected and messaged.
If Db2 Query Monitor runs out of ISM error message blocks, consolidation might not occur and duplicate messages for similar storage constraint events might be generated in the log.
- Integers in the range 16 - 8192
