The TIBCO iProcess Workspace makes Remote Procedure Calls (RPC) to the server using ports. This means the TIBCO iProcess Workspace makes calls to the TIBCO iProcess Engine to find out information such as what work queues and work items it needs to display. It also means that procedures can be started from one computer but actually be running on another computer on the network. There are a number of reasons why this might happen:
The connection between the RPC client computers and RPC servers is serviced by a program known as the portmapper (or
rpcbind). The portmapper provides a directory for the RPC services on the computer on which it runs.
