Lock files and members for DDM

Putting object locks on DDM files and their associated remote files requires special consideration.

• Allocate Object (ALCOBJ) and Deallocate Object (DLCOBJ) commands
  The ALCOBJ command locks DDM files on the source server and the associated remote files on the target servers.
• Work with Job (WRKJOB) and Work with Object Locks (WRKOBJLCK) commands
  For both the WRKOBJLCK command and menu option 12 (Work with locks, if active) of the WRKJOB command, only the locks held for the local DDM files are shown, not locks held for the remote files (or for their members).
