Replica sets

A cluster of ISAM servers using the distributed session cache to share sessions is called a replica set.

Servers in the replica set can use the distributed session cache to provide failover of user sessions. A client session created by one member of a replica set can be used unmodified by another.

Certain policies, including maximum concurrent session policy and policies that affect credential change, can apply consistently across a replica set. From the user and administrator points of view, sessions exist as a single entity across a replica set.
