Use care when enabling WebSphere Application Server logging. Performance degradation can occur when the WebSphere® Application Server logging level is enabled at a level higher than INFO (for example, FINE, FINER, or FINEST).
See the IBM WebSphere Application Server Information Center (V8.0, V8.5) for details on how to configure Java logging for WebSphere Application Server profiles in which Rational ClearQuest Web server is installed.
