Most application servers include a clustering service that you can use with your EclipseLink application.
To use EclipseLink with an application server cluster, use this general procedure:
Install the eclipselink.jar
file (and include it in the classpath) on each application server in the cluster to which you deploy EclipseLink applications.
Configure the cache consistency options appropriate for your application.
For more information, see Chapter 9, "Understanding Caching."
Configure the coordinated cache support for your application server, if available.
For more information, see Chapter 9, "Understanding Caching."
Configure clustering on each application server.
For more information, see your application server documentation.
