Adding a server to a PolicyCenter cluster

PolicyCenter does not require that you use the cluster registry in file config.xml to define cluster members. Its use is optional in that regard. Instead:

• You can specify the server ID and server roles from the command prompt at server startup using JVM command options.
• Or, you can specify a subset of the cluster server members in the cluster registry and set other server properties from the command prompt.

For example, you can define the set of servers assigned the batch server role in the cluster registry and specify the remaining server IDs through JVM options at server start.

Server specified in config.xml

It is possible to perform a rolling upgrade of each server instance in the cluster to upgrade the cluster registry of each individual server instance in turn.
