queue file
queue file. In the Transfer X400 gateway, a file in the queue manager that consists of three
logical queues: the ADMIN queue with entries for MR group registration, the
MESSAGE queue with entries for import work, and the EXPORT queue with entries for
export work.
queue manager. A queuing facility that lets Transfer requesters add an entry and retrieve an
entry from a queue for processing. The queue manager can be used independently of
Transfer; it is automatically installed when you configure the Transfer X400 gateway
and is also required for gateways using the Gateway Programmatic Interface (GPI).
reason code. A value indicating why a message could not be delivered (called a “non-
delivery-reason-code,” in the X.411 standard).
receipt notification. Indicates to the sender of a message that the message was received and
read by the intended recipient.
$RECEIVE. The name of a special file through which a process receives and optionally
replies to messages from other processes.
recipient. A person or application that receives a message from a message handling system.
registration database. An OSI/MHS database that consists of three files: APPL, route, and
adjacent MTA.
reliable transfer service. See RTSE.
remote MTA. An adjacent or nonadjacent MTA. Any MTA other than your local OSI/MHS
subsystem.
Remote Operations Service. See ROSE.
remote system. In Compaq terms, any system within an Expand network that is not the local
system.
remote user agent. See RUA.
report. A notification generated by the OSI/MHS subsystem that tells the user whether the
message has been sent.
request primitive. In OSI, a primitive issued when a service user wants the service to do
some work. This is one of four types of service primitives. See also service primitive.
reserved object. An object on the input queue that the client program has started transferring
in and to which the GPI has assigned an object identifier. A client program can examine
or copy a reserved object (and its attributes) but not modify it.
response. In OSI, see response primitive.
In DSM, the information or confirmation supplied (as part of a response message) to an
application by a subsystem in reaction to a DSM command.
