If the target server is not another iSeries™ server or System/38™, only the DDM architecture commands defined in Level 2.0 and earlier of the DDM architecture are used.
If the target is an iSeries server or a System/38, then iSeries server and System/38 extensions to the architecture are used to support some operations not defined by the Level 2.0 DDM architecture. Examples of System/38 and iSeries extensions to the architecture are the Submit Remote Command (SBMRMTCMD) and processing file members of remote files. For creating a file when the source is an iSeries server and the target is also an iSeries server, an iSeries extension is used.
Target servers that are not iSeries servers or System/38s might not be capable of handling all of the functions that an iSeries server or a System/38 can handle. For example, a System/36™ does not support relative record processing and keyed record processing with one open operation; therefore, programs that mix accessing records in a file by key or relative record do not work if the file is on a System/36. In addition, target servers that do not support Level 2.0 of the DDM architecture can only handle functions defined in the level they support.
Neither the System/36 nor the System/38 support access to folder management objects.
An iSeries server as a source server does not support access to stream files and directories.
