Reclaiming DDM resources

 

The Reclaim Distributed Data Management Conversations (RCLDDMCNV) command reclaims all application conversations that are not currently being used by a source job, even if the DDMCNV attribute value for the job is *KEEP.

The command allows you to reclaim unused DDM conversations without closing all open files or doing any of the other functions performed by the Reclaim Resources (RCLRSC) command.

The Reclaim Distributed Data Management Conversations (RCLDDMCNV) command applies to the DDM conversations for the job on the application requester (AR) in which the command is entered. There is an associated application server (AS) job for the DDM conversation used by the AR job. The AS job ends automatically when the associated DDM conversation ends. For TCP/IP conversations that end, the AS job is normally a prestart job and is usually recycled rather than ended.

Although this command applies to all DDM conversations used by a job, using it does not mean that all of them will be reclaimed. A conversation is reclaimed only if it is not being actively used. If commitment control is used, a COMMIT or ROLLBACK operation might have to be done before a DDM conversation can be reclaimed.
