Several FileNet® P8 processes require the Remote Method Invocation (RMI) mechanism that is built into the Java™ environment.
Java objects are automatically registered in the RMI registry. Communication between an RMI object and RMI clients occurs via the RMI registry for the port with which the RMI object is registered. An RMI object binds itself to the RMI registry; the RMI registry then routes requests coming to and going from that RMI object appropriately through the system.
By default, processes that communicate via RMI run on port 32771. Generally, there is no need to change the default port unless you are working around a conflict with another software package that requires port 32771. You can specify a different port when you start Process Simulator. For details about specifying Process Simulator ports at startup, see the Process Simulator general properties information.
