TIBCO iProcess Engine Process Structure
To understand the flow of data through the TIBCO iProcess Engine and the relationship of TIBCO iProcess Engine processes, you can think of the TIBCO iProcess Engine as being split into the following four areas.
A TIBCO iProcess Engine process operates in either the foreground or background layer. The Mbox set provides the communication link between the foreground and background processes. This is the Messaging layer where instructions are sent from the foreground to the background and vice versa.
The foreground area deals with the user interaction, list of queues and their contents. The background processes perform the case processing.
The Process Sentinels keep control of all the processes to make sure they are always running.
