Problem summary


    

  • ****************************************************************
* USERS AFFECTED:  All WebSphere eXtreme Scale customers who   *
*                  use the COPY_TO_BYTES copy mode.            *
****************************************************************
* PROBLEM DESCRIPTION: When querying dynamic cache data on     *
*                      the server, XDF inflates the value      *
*                      attribute, which contains the user      *
*                      object.                                 *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Instead of inflating the empty templates attribute, XDF tries
to inflate a user object on the server, while querying dynamic
cache data.

    



Problem conclusion


    

  • Missing logic in XDF causes the inflating of objects to be
skipped. The code logic has been updated so that objects are
correctly inflated.
