iSeries Access Family considerations for DDM

The iSeries™ Access Family supports DDM for accessing remote files, with limitations.

Note: iSeries Business Graphics Utility does not support DDM.

The transfer function in iSeries Access Family can be used with DDM to transfer data between a personal computer attached to a local iSeries server and another remote server.

When the transfer function is being used, the remote system must be an iSeries system or a System/38™. The iSeries Access Family copy commands, Copy to PC Document (CPYTOPCD) and Copy from PC Document (CPYFRMPCD), can be used to copy data on a host server or between host servers.

The figure here shows a personal computer attached to the local iSeries server. The iSeries Access Family user can access data on remote servers through a DDM file defined on the local iSeries server. The iSeries server with the personal computer attached can only be the source server.

The iSeries Access Family transfer function can be used by a personal computer user to transfer data from a remote file to the personal computer, or to transfer data from the personal computer to a remote file. Only a personal computer user can start the requests, not an iSeries user.
Figure 1. Use DDM with iSeries Access Family
The iSeries Access Family copy commands can be used with DDM to copy data from a personal computer document located on the local iSeries server to a database file on the remote iSeries server, or to copy data to a personal computer document on the local iSeries server from a database file on the remote iSeries server.

Note: For iSeries Access Family, database query allows accessing of multiple remote files (by using DDM files) at the same time.

iSeries Access Family transfer function considerations
A personal computer user can use the transfer function in iSeries Access Family and the DDM support on the local iSeries server to which the personal computer is attached either to transfer data from the personal computer to a remote file, or to transfer data from a remote file to the personal computer.
iSeries Access Family copy command considerations
The iSeries CL command Copy from Personal Computer Document (CPYFRMPCD) used in iSeries Access Family can be used to copy data from a document located either on an iSeries server to a database file member located on the same iSeries server or on a remote iSeries server using DDM.
