29.2.1 QM: Queue Management Utility

PMDF QM is a utility program which allows inspection and manipulation of queued messages. PMDF QM has two modes: maintenance mode and user mode. Maintenance mode can be used to inspect and manipulate the channel queue directories and the messages contained in them. Privileges sufficient to read, create, and delete files in the channel queue directory tree as well as read and update the queue cache database are required to use maintenance mode. User mode is a very restricted version of maintenance mode which allows unprivileged users to read their own messages from the queues and to return them (bounce them) back to their originator if desired. Users' own messages are messages which they themselves have sent or were posted to a list they own. They are not messages destined for the user. User mode is documented in the PMDF User's Guide, OpenVMS Edition.

To run PMDF QM in maintenance mode, issue the command

$ PMDF QM/MAINTENANCE

Use the EXIT or QUIT command to exit PMDF QM.

The commands accepted by this utility² are summarized in Table 29-2 below.
