DDM-related CL command lists

 

The control language (CL) commands that have a specific relationship with DDM are grouped in charts in these topics to show the command functions that are available with DDM, those having common limitations when used with DDM, and those that cannot be used with DDM. Notes:

1. Not all of the CL commands on an iSeries™ server are shown in these topics. Only those that are intended (or recommended) by IBM^® for use with DDM or those specifically not intended for DDM use are shown. The intended use can be either for commands that are run on the source server to affect a remote file on the target server, or for commands that are submitted to the target server by using the Submit Remote Command (SBMRMTCMD) command to run there.

2. Some of these commands appear in more than one of the following charts.

The charts in these topics show:

• Commands affecting only the DDM file:

  Object-oriented commands that can be used with DDM files, but do not affect the associated remote files. The Create DDM File (CRTDDMF), Change DDM File (CHGDDMF), and Reclaim DDM Conversations (RCLDDMCNV) commands are included in this group.

• Commands affecting both the DDM file and the remote file:

  • File management commands that require that the target server be another iSeries server or a System/38™. The SBMRMTCMD command is included in this group.

  • Member-related commands that can be used in some way on remote files.

  • Source file commands that can operate on source files while DDM is being used.

  These commands, normally used for processing local files, can (transparently to the programs) process remote files when one of their parameters specifies the name of a DDM file.

• Commands that cannot be used with DDM.

Many of these commands, when limited as shown in the charts, can still be submitted by the SBMRMTCMD command to a target server (an iSeries server or a System/38 only) to run, but it might not be useful to do so.

• Object-oriented commands with DDM
  The DDM file object on the source iSeries server can be accessed by these object-oriented CL commands. These commands work with DDM files as they normally do with any other files on the local server.

• Target iSeries-required file management commands
  These CL commands can be used only when the target server is another iSeries server or System/38.

• Member-related commands with DDM
  Database file operations that apply to a member can be used by DDM.

• Commands not supporting DDM
  These CL commands are not supported for DDM files. However, useful results for some of them might be produced on a target iSeries server or a System/38 using DDM if they are submitted on the Submit Remote Command (SBMRMTCMD) command to run on the target server.

• Source file commands
  If the target server is an iSeries server or a System/38, these CL commands can support a DDM file as a source file (on the SRCFILE parameter).

• DDM-related CL command summary charts
  This topic shows summary charts containing most of the control language (CL) commands used with DDM.
