Error description

• Some Dynacache MBean statistics that deal with replicated
  caches are not updated. The Dynacache runtime code is NOT
  correctly incrementing the value of the following statistics:
  
  RemoteObjectHits :
  The number of requests for cacheable objects that are served
  from other JVMs in the cluster. (PushPull mode)
  
  RemoteObjectMisses :
  The number of requests for cacheable objects that were not
  found from other JVMs in the cluster. (PushPull mode)
  
  RemoteObjectUpdates :
  The number of cacheable objects that are received from other
  JVMs in the cluster. (Push mode)
  
  RemoteObjectUpdateSize :
  The size of cacheable objects that are received from other
  JVMs in the cluster. (Push mode)
  
  RemoteUpdateNotifications :
  The number of notifications that identify that an object is
  updated at another server. (The number of entries in the
  push-pull table).

Problem conclusion

• Dynacache component code has been updated to correctly update
  MBean statistics when caches instances are replicated with DRS.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.1.0.29.  Please refer to the Recommended Updates
