Hi, To support automatic failover for session states, WLServer 6.1 replicates the session state object in memory. This process creates a primary session state, which resides on the Server to which the client first connects,and a secondary replica of the session state on another WebLogic Server instance in the cluster.The replica is always kept up-to-date so that it may be used if the server that hosts the servlet fails. The process of copying a state from one instance to another is called in-memory replication.To utilize in-memory replication for HTTP session states, you must access the WebLogic Server cluster using either: Load balancing hardware, or A collection of Web servers with WebLogic proxy plug-ins (configuredidentically). If you choose to use load balancing hardware instead of a proxy plug-in, you must use hardware that supports SSL persistence and passive cookie persistence. Passive cookie persistence enables WebLogic Server to write cookies (containing information about the location of replicated HTTP session states) through the load balancer to the client. The load balancer, in turn, interprets an identifier in the clientÂ’s cookie to maintain the relationship between the client and the primary WebLogic Server hosting the HTTP session state. Or you can use File or JDBC based session persistence on a cluster.This type is slower than In-memory based replication. Is it all u require or any thing else that i missed.
