![]() APAR status Closed as program error. Error description Currently, the performance of the Admin Console for WebSphere Application Server v5.0 for z/OS needs to be improved. This performance degradation causes the 'Status' icon for installed / started applications, as well as servers in nodes that have been started, to be 'Unavailable'. This is incorrect, as the actual availability of these applications/servers is not 'Unavailable' but, in fact, 'Started'. Other problems may occur as a result of the degraded performance of the WebSphere admin function. The above is a single example.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: The Status indicators on the * * Administrative Console client are too * * slow to return the state, sometimes * * causing timeouts and incorrect states. * **************************************************************** * RECOMMENDATION: * **************************************************************** The current model did not scale well to large numbers of servers and applications, so an event driven model was built. It is composed of a series of Event Caches that propagate information, and listeners that act on that information.Problem conclusion The current model is a polling model, where every server/ app is queried individually, this model has been changed to an event driven model. APAR PQ81599 is associated with SERVICE LEVEL W502001 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
