Server Processes

The following table shows the server processes that are initially set up when iProcess Engine is installed. The details of each process are stored in the process_config table. Note that:

• Process Sentinels  are responsible for controlling all the TIBCO iProcess Engine processes. If a node cluster architecture is used, then Process Sentinels will exist on each server to manage the processes running on that server.
• Foreground processes  are responsible for communicating with TIBCO iProcess Workspaces and for passing any TIBCO iProcess Workspace requests such as released work items to the background area for processing.
Note: All foreground processes must run on the master server.
• Background processes  are responsible for processing message instructions received from the clients such as releasing a step or forwarding a step. They also monitor and process any deadlines that have been set up in the procedure and manage case prediction.
