Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of WebSphere Application Server    *
    *                 V7.0 for z/OS that leverage servlet          *
    *                 caching and the Edge Side Include protocol.  *
    *                                                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: Edge Side Include (ESI)                 *
    *                      cache statistics and processes not      *
    *                      showing up on the cache monitor         *

    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Under stress, WebSphere DynaCache does not communicate cache
    statistics and other control information correctly with the ESI
    surrogate server. The ESI surrogate can be an IBM HTTP server
    (IHS) with the WebSphere plugin or the WebSphere Proxy Server.
    When a problem occurs, the connection between IHS and WebSphere
    Dynacache is broken and  the CacheMonitor application
    does NOT show any ESI edge statistics.
    

Problem conclusion

  • The communication channel between the ESI surrogate server and
    the WebSphere Application Server on z/OS has been made
    more robust. The connection will now stay up, until the
    application server or the ESI surrogate server is stopped.
    
    APAR PK90168 is currently targeted for inclusion in Service
    Level (Fix Pack) 7.0.0.5 of WebSphere Application Server V7.0.
