PK01814: HEAP VALUES RETURNED FROM PMI ARE INCORRECT AFTER SERVANT REGIONIS RECYCLED. | |||||||||||||||||||||||||||||||||||||||||||

![]() APAR status Closed as program error. Error description The application receives freeMemory, totalMemory and usedMemory data by using PMI. Usually, these data have correct values. However, when a servant region was restarted (by cancel command), the Heap values returned from PMI are incorrect. Further diagnosis confirms that when a servant is terminated, the PMI data for the terminated servant is retained. In the case of freeMemory, totalMemory and usedMemory (as well as, numThreadsStarted and numThreadsDead) this information is misleading because it gets aggregated in with the values for active servants. Note: this problem does not occur if all CR and SRs are recycledLocal fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: PMI data for jvmRuntimeModule * * is incorrect after a servant * * terminates. * **************************************************************** * RECOMMENDATION: * **************************************************************** The PMI values for freeMemory, totalMemory and usedMemory (within jvmRuntimeModule) are incorrect after a servant terminates. The values for the terminated servant are being included in the aggregated totals.Problem conclusion PMI was modified to not include the values for terminated servants when aggregating the freeMemory, totalMemory and usedMemory values. APAR PK01814 is associated with SERVICE LEVEL W502027 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
