Purpose

The Directory Services User Exit is the Client Manager's implementation of Transaction routing. Transaction routing is a conceptual process that lets cooperative flow data be routed from a Distributed Process Client (DPC) to a programmatically determined Distributed Process Server (DPS). The Distributed Processing—Client Manager User Guide discusses transaction routing and directory services in detail.

This initialization interface is called once and does the Client Manager call the first directory service function. In the supplied sample implementation, this routine reads the transaction code to server mapping information from the iefdir.trn file.

Note: For more information about updating the IEFDIR.TRN file, see the section Directory Services DLL Functions in the Distributed Processing—Client Manager User Guide.
