[jboss-user] [JBoss Portal] - Memory utilization in session replication

Tejas Pajai [http://community.jboss.org/people/tejaspajai] created the discussion "Memory utilization in session replication" To view the discussion, visit: http://community.jboss.org/message/575416#575416 -------------------------------------------------------------- Hi, We are using jboss-portal-2.6.5.SP1. Our application is memory intensive. Sessions hold reference to a lot of data. Due to extensive memory usage we have started facing heap issues in production. Increasing the heap is one option, but we are also planning to go for a clustered environment with session replication to reduce the load on a single server. My question is: How does session replication work in JBoss? Is it: A. are the replicated sessions saved in memory on each node in the cluster OR B. are they written to physical disk on the nodes to which they are replicated and recovered when necessary. Logically, it should be 'B', otherwise scaling the system would make no sense if each node in the cluster is loaded with all the sessions information of all the nodes. Please feel free to ask if my question is not clear. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/575416#575416] Start a new discussion in JBoss Portal at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
