PH34669: HCQC110 DB2 COMMON ACCESS COLLECTOR MONITORING AGENT DE-INSTALL FAILURE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If S-TAP or QM is cancelled immediately after startup
  (e.g. within 5 seconds,) the common collector
  can reference the prior incidence of S-TAP/QM
  

Local fix

• The workaround is not to cancel the started task until it's
  fully initialized

  ABEND DC2-0F9 in CQC#REST when attempting to detach a memory
  object that was not allocated due to an early termination of
  the Query Monitor or Security Guardium S-TAP initialization
  process.
  

Problem conclusion

• If Query Monitor or Security Guardium S-TAP were cancelled
  immediately after startup, the next start picked up references
  to the prior instance of Query Monitor or Security Guardium
  S-TAP. The logic was corrected to avoid picking up memory
  references from prior executions.
