System/36 source to iSeries target considerations for DDM

 

When System/36™ is using DDM to communicate as a source server to access files on an iSeries™ target server, the information in this topic applies and should be considered.

• When System/36 creates a direct file on an iSeries server, the iSeries server creates a nonkeyed physical file with the maximum number of records, and prepares them as deleted records. The DDM architecture command Clear File (CLRFIL), when issued from a non-iSeries source server, clears and prepares the file; the CL command Clear Physical File Member (CLRPFM), when issued by a local or remote iSeries server, does not prepare the file.

• System/36 supports a maximum of three key definitions for logical files and one key definition for keyed physical files.

• Nondelete-capable direct files cannot be created using DDM on an iSeries server. In addition, the iSeries server does not support nondelete-capable files for all file organizations.
