DDM Files

ILE RPG programs access files on remote systems through distributed data management (DDM). DDM allows application programs on one system to use files stored on a remote system as database files. No special statements are required in ILE RPG programs to support DDM files.

A DDM file is created by a user or program on a local (source) system. This file (with object type *FILE) identifies a file that is kept on a remote (target) system. The DDM file provides the information needed for a local system to locate a remote system and to access the data in the source file. For more information about using DDM and creating DDM files, refer to the DB2® for i section of the Database and File Systems category in the IBM® i Information Center at this Web site - http://www.ibm.com/systems/i/infocenter/.
