PK32399: HIGH CPU CONSUMPTION IN DGOZPMS (PERFORMANCE WAREHOUSE)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the OMEGAMON XE server component Performance Warehouse
  (PWH) is activated and processes and process steps have been
  scheduled to execute repeatedly the CPU consumption of the
  PWH module DGOZPMS increases significantly over time.
  The high CPU consumption is detected by the data server which
  issues message FPEV0158W, starts the internal server traces and
  will finally reattach the affected subtask if the high CPU
  consumption persists.
