datasource
Downloadable files
Abstract
Under Load, the WebSphere® Application Server V4.0
datasource counters miscount.
Download Description
USERS AFFECTED:
WebSphere Application Server Performance Monitoring Infrastructure (PMI)
users who want to monitor the performance data for a 4.0 datasource in
V5.0.
PROBLEM DESCRIPTION:
Under heavy workload, the percentUsed value in 4.0 datasource may be
negative.
4.0 connection manager passed wrong parameters to PMI. As a result, the
number of connections released could be greater than the number of
connections allocated, resulting in a negative percentUsed.
PROBLEM CONCLUSION:
Instead of using the numbers passed by connection manager, PMI tracks
related numbers itself. This fixes the problem.
Prerequisites
None
Installation Instructions
