Other DDM-related functions involving remote files

 

Besides accessing remote files for data record I/O operations, other operations related to remote files can be performed. These are briefly described in these topics.

• Perform file management functions on remote servers
  i5/OS^® DDM supports creating, deleting, or renaming of files on a remote server.

• Lock files and members for DDM
  Putting object locks on DDM files and their associated remote files requires special consideration.

• Control DDM conversations
  Normally, the DDM conversations associated with a source server job are kept active until one of the conditions described in this topic is met.

• Display DDM remote file information
  The CL commands Display File Description (DSPFD) and Display File Field Description (DSPFFD) can be used by an iSeries™ source server user to display the attributes of one or more DDM files on the source server, or to display the attributes of one or more remote files on a target server.

• Display DDM remote file records
  The Display Physical File Member (DSPPFM) command can be used to display a remote file on a target server.

• Coded character set identifier with DDM
  Support for the national language of any country requires the proper handling of a set of characters.

• Use of object distribution
  Although DDM file names can be specified on the Send Network File (SNDNETF) and Receive Network File (RCVNETF) commands, these commands should be run, whenever possible, on the server where the data actually exists. Therefore, if both servers are iSeries servers and both are part of a SNADS network, object distribution can be used instead of DDM to transfer the data between them.

• Use of object distribution with DDM
  You can also use both SNADS (on iSeries servers) and DDM (on iSeries servers and non-iSeries servers) to transfer files between iSeries servers and servers that are not part of a SNADS network but have DDM installed.
