PI93812: COLLECTION OF DB2 UTILITY EVENT MAY RESULT IN HIGH CPU USAGE OR OTHER UNEXPECTED RESULTS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If collection of DB2 Utilties is enabled in STAP V10.1.3, there
  is a possibility during and/or after collection of a utilty
  event, DB2 activity may enter a loop.
  

Local fix

• The workaround for this issue is to modify the activated policy
  defined at the appliance by removing all instances of the
  "IBM DB2 UTILITIES" from the Command filter, for all rules
  included in the policy. The "IBM DB2 UTILITIES" may need to be
  removed from the predefined group Command group "DB2/Z General
  Audit Types". By removing "IBM DB2 UTILITIES" from the
  activated policy, the z/OS Agent will no longer execute the code
  to collect utility events and the text for those events, thus
  avoiding the overlay causing the loop.
  Note that by implementing this workaround, DB2 Utilities will no
  longer be audited until the APAR is available and DB2 Utilities
  have been added to the active policy.
