      Hi Siva,

      We have three nodes in a cluster, we have done the same setting which you have mentioned to create Object Cache Instances. But sometimes values are getting duplicated in the cache. I am filling in values in these caches during server start up with the help of Logout filters. If I restart all the applications again in the same sequence I am not able to recreate them.
