Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere eXtreme Scale        *
  *                  Version 7.0.0.0 who use the Hibernate       *
  *                  Level 2 cache implementation.               *
  ****************************************************************
  * PROBLEM DESCRIPTION: After running a Hibernate               *
  *                      query, applications do not perform      *
  *                      well when a large data set is           *
  *                      retrieved.                              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the eXtreme Scale Hibernate Level 2 cache plug-in
  is enabled, Hibernate queries that return larger data set run
  slowly. To improve performance, configuration options were
  added to enable write behind capability.  See the
  information center for more information about the new
  configuration options.
  

Problem conclusion

• A future cumulative fix will correct the problem for WebSphere
  eXtreme Scale Version 7.0.
