FPEV0158W <V1> <V2> DATA SERVER DETECTED HIGH CYCLE TASK USAGE (<F3> %) IN TASK <V4>.

Explanation

OMEGAMON for Db2 PE detects high cycle task usage for one of its components.
  • <V1> is the Db2 subsystem ID.
  • <V2> is the local time.
  • <F3> is the detected cycle usage.
  • <V4> is the name of the task.

The OMEGAMON® Collector subtask PESERVER periodically monitors the CPU cycle consumption of its subtasks in intervals of one minute. If the CPU cycle consumption of a subtask exceeds an internal threshold value, the server issues message FPEV0158W. The threshold value may vary with situation and subtask. Cycle usage is not percentage usage of total system CPU, but is the percentage usage of the maximum CPU available to that task - typically percentage usage of a single CPU. Additionally, the internal server traces are started and message FPEV0162W is issued. If the cycle consumption of the subtask falls below the threshold within the next sample interval, the internal traces are switched off and normal processing continues. If the CPU consumption of the subtask remains above the threshold within the next sample interval, a dump is taken and message FPEV0159W is issued. If the cycle consumption of the subtask continues to exceed the threshold, the subtask will finally be reattached and message FPEV0161W is issued.

User response

This might occur sporadic because of brief peaks in resource usage and can be ignored. If this occurs regularly without obvious cause, then the server trace can be sent to IBM® support for investigation.
