Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server using the ExtensionClassloader       *
    *                  method to define an alternate cache         *
    *                  provider.                                   *
    ****************************************************************
    * PROBLEM DESCRIPTION: Error DYNA1066E is logged for cache     *
    *                      providers except for the WebSphere      *
    *                      eXtreme Scale (WXS) alternate cache     *
    *                      provider.                               *
    ****************************************************************
    * RECOMMENDATION:  Use the preferred method to define an       *
    *                  alternate cache provider, an OSGI bundle.   *
    ****************************************************************
    The dynacache alternate cache provider loading code
    hardcoded the WXS class name for the ExtensionClassloader
    method of defining an alternate cache provider.  No other
    alternate cache providers are attempted to be loaded.
    

Problem conclusion

  • Dynacache will attempt to load any class defined as an
    alternate cache provider in a cache instance definition.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.43, 8.0.0.14, 8.5.5.12 and 9.0.0.4.  Please
