TIBCO iProcess Engine
The TIBCO iProcess Engine processes all requests from iProcess applications, as well as maintains all data in the iProcess database.
A TIBCO iProcess Engine installation on one machine is known as a TIBCO iProcess Engine node. Installing the iProcess Engine on multiple machines that all use the same database instance is known as a node cluster architecture. In the node cluster architecture, you can have a number of iProcess Engine processes running on different machines to improve load balancing and performance. However, all the iProcess Engine case data such as fields and their values in forms will be stored in one iProcess Engine database instance.
