PK69639: CQM1055E WHEN DISABLE SUMMARY REPORTING SET. ALSO, SQLCODE -925 CAN OCCUR ON A STATEMENT WITH AN EXPLICIT COMMIT.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Message CQM1055E erroneously issued as a result of logic error
  that can occur when disable summary reporting set for a thread
  started before CQM was started, that is in a fetch loop.
  
  Sample error message occurs even though PK62420 is APPLYd:
     CQM1055E DB2 QUERY MONITOR DQMB IS EXPERIENCING STORAGE
                CONSTRAINTS, DATA LOSS MAY OCCUR, REASON=01000000
  
  This APAR also corrects a -925 SQLCODE erroneously issued on a
  statement with an explicit commit, while the QM collector is
  running.
  
  Sample error message:
  
    DSNT408I SQLCODE = -925, ERROR: COMMIT NOT VALID IN IMS,
             CICS OR RRSAF ENVIRONMENT
  
  OTHER KEYWORDS: SQLCODE925 925 SQL925 CQM1055
  

Local fix

• The storage constraint can be relieved by stopping the workload
  or restarting CQM, as described below.
  
  Workaround option A (requires stopping/restarting the looping
  DB2 thread):
  
  The storage constraint can be relieved by stopping the thread
  and restarting it after CQM has installed its monitor for that
  DB2.
  
  Workaround option B (requires stopping/restarting the Query
  Monitor Collector):
  
  An alternative workaround requires setting the monitoring
  profile parameter DISABLE SUMMARY REPORTING to 'N', for all
  workloads (for each profile line in the active profile), and
  restarting the Query Monitor Collector.
  
  Note that DISABLE SUMMARY REPORTING 'Y' requires INCLUDE/EXCLUDE
  to be set to 'E'.
  
  
  Example:
  
  INCLUDE/EXCLUDE             E     (I=Include, E=Exclude)
  
  Disable Summary Reporting   Y  (Y/N)   Gather Host Variables  N
  (Y/N)
