  *                  Version 6.1 and 7.0 who are using the       *
  *                  ObjectGrid component in a WebSphere         *

  *                      a WebSphere transaction global          *
  *                      context, the WebSphere transaction      *

  * RECOMMENDATION:                                              *
  ****************************************************************
  When eXtreme Scale clients and servers are run in WebSphere
  Application Server processes, the WebSphere Application Server
  transaction component enlists the server as a resource during
  client to server communication. The WebSphere transaction
  component rolls back the WebSphere transaction when the
  transaction duration is longer than the configured WebSphere
  transaction timeout value.  The eXtreme Scale client code was
  changed to prevent the WebSphere transaction component from
  enlisting eXtreme Scale servers as resources in the WebSphere
  transaction.
  

Problem conclusion

• An interim fix will be made available for this APAR.  A future
  cumulative fix will correct the problem for WebSphere eXtreme
  Scale Version 6.1 and 7.0.

Temporary fix

• Suspend the WebSphere transaction before calling any eXtreme
  Scale client operations.
