Replication domains

When you create clusters and cluster members, it is useful to understand the various replications domains that are used to create clusters.

Several replication domains are used within an IBM® InfoSphere® Information Server cluster:

  • If you chose a memory-to-memory replication approach for HTTP session management, the replication domain replicates HTTP session information and the stateful EJB state across the cluster.
  • Another type of replication domain is used to replicate cached data (data-cached applications that are part of the InfoSphere Information Server suite).

Both types of replication domains replicate cached data to all cluster members (a full-domain strategy). Replication domains are created automatically during the InfoSphere Information Server installation. You use the default IBM WebSphere® Application Server settings during installation. You can change these settings from the WebSphere Application Server administrative console after the InfoSphere Information Server installation.
