Replication entry

A replication entry, or replicator, is a runtime component that handles the transfer of internal WebSphere Application Server data.

WebSphere Application Server processes can connect to any replicator within a domain to receive data from other processes connected to any other replicator in the same domain. If a replicator fails, the application server processes automatically attempt to connect to another replicator in the domain to recover data.

You can define replicators to operate either within a running application server process or for a separate process. Replicators are not enabled by default. You must define replicators as needed as part of application server and cluster management.

You can keep the default settings for replicators or specify settings values for replicators that better suit your server configuration. The default configuration options are suitable for most scenarios.
