![]() APAR status Closed as program error. Error description Customer uses RequestDispatcher to dispatch a request. After going from W502011 to W502015, the request does not complete. The failure can be forced by clearing browser cache but also occurs after some time. The problem goes away for awhile if the application server is restarted.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: After PQ89799 Servlet responses are not * * being automatically flushed at service * * method termination. * **************************************************************** * RECOMMENDATION: * **************************************************************** PQ89799 introduced logic to reduce the number of Web Container internally-initiated flush() calls in order to reduce chatter between the Controller and Servant regions. However, if a servlet uses an OutputStream rather than a Writer then the final required automatic flush will not occur with PQ89799 applied. This applies to WebSphere Application Server V5.0 for z/OS only.Problem conclusion The Web Container in WebSphere Application Server V5.0 for z/OS has been changed to cause the final automatic required flush to be driven. APAR PQ95568 is associated with SERVICE LEVEL W502017 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
