When the name of a DDM file is specified on the Deallocate Object (DLCOBJ) command on the source server, the command deallocates the DDM file on the source server and its associated file or file member on a target server.
The command releases the locks that were placed on the paired files on both the source and target servers by the Allocate Object (ALCOBJ) command. One or more pairs of files (DDM files on the source server and remote files on one or more target servers) can be deallocated at the same time.
