RPC Pool Server
This process is responsible for handling RPC requests from a TIBCO iProcess Workspace to access and update data in the iProcess Engine instance.
A number of RPC pool servers can be created by the RPC Listener when the TIBCO iProcess Engine is started and each RPC server will be responsible for a configured pool of TIBCO iProcess Workspace connections. You can set up a number of pool servers that are pre-loaded if you have lots of TIBCO iProcess Workspaces logging in quickly. You do this by defining the PRE_LOAD_POOL_SERVERS parameter in the SWDIR\etc\staffcfg file. TIBCO iProcess Workspaces can be allocated to pool servers using either a round robin or load balanced method.
The RPC Pool servers are started by the RPC TCP Listener. The number of users that each pool server can support is configured using the MAX_USERS_PER_PROCESS parameter in the SWDIR\etc\staffcfg file.
