Introduction to Management
Programming for OSI/MHS
The Compaq Open Systems Interconnection/Message Handling System (OSI/MHS)
enables people and application processes to exchange messages within a network of
computer systems. OSI/MHS is based on the CCITT X.400 series of recommendations.
Your Compaq implementation may contain several OSI/MHS subsystems connected
across a complex computer network. Compaq provides one password server, called the
Master Password Server, which gives a master user access to any mailbox.
To manage large systems or networks efficiently, it is beneficial to transfer many of the
routine management tasks to the computer system or network itself. This manual
describes how to design and code applications that manage the OSI/MHS subsystem.

Management Programming for OSI/MHS
The OSI/MHS subsystem supports the Compaq Distributed Systems Management
(DSM) facilities. In the context of DSM, a subsystem is a set of processes that manages
a cohesive set of objects in the computer system. A subsystem can be managed by a
person using an interactive text interface like the Subsystem Control Facility (SCF) or
