Arbortext PE Request Manager components are declared in the e3config.xml file by the following elements:

The SubprocessPools element contains a series of SubprocessPool elements. Each SubprocessPool has SubprocessContext and TestSet child elements as well as many attributes. For information on the attributes, refer to Arbortext PE sub-process Pool Management. The SubprocessContext element supports Parameter child elements, and their values are passed to every Arbortext PE sub-process in the pool when it is initialized.

A series of tests can be defined to determine whether a request can be processed by Arbortext PE sub-processes in the pool. The TestSet element contains a set of Test elements, which can be grouped by And and Or elements. A Test element refers to a RequestSelector with an id attribute that matches the name of the test. A test evaluates to true if its referenced RequestSelector returns true when offered a request for evaluation. An And element contains Test, And, and Or elements, which means that it evaluates to true if every element it contains evaluates to true. An Or element contains Test, And, and Or elements, and it evaluates to true for any element that evaluates to true.
