Create a DDM file using RDB directory entry information

You can create a DDM file that uses the remote location information from a relational database (RDB) directory entry.

Each DDM file that uses an RDB directory entry contains the following information.

DDM file value and description of values

DDM file name
The name of the DDM file on the source server that is used to identify a specific remote file.
Remote file name
The actual file name of the remote file; that is, the name by which it is known on the target server.
Remote location name
Specify *RDB to indicate that the remote location information is taken from an RDB directory entry.
Relational database
The name of the relational database entry used for the remote location information. The remote location information in the RDB directory entry is used to establish the data link to the target server (remote location), over which a DDM conversation is established when the DDM file is accessed.

You need to specify an RDB directory entry associated with an auxiliary storage pool (ASP) group for the DDM file's remote location information to access that ASP group.
