What You Need to Know
To integrate an RUA with OSI/MHS, you define the required MHS components
(message stores, RS processes, and PDU stores) and describe the RUA to OSI/MHS as
an application (APPL). The collective name for an RS process and its PDU store is RS
group.
To write an RUA compatible with OSI/MHS, you use tools available on the remote
system to develop an application compliant with the X.400 P7 protocol.
What You Need to Know
To add an RUA to your OSI/MHS configuration, you must know how to perform the
following functions:
•
Set up your MHS environment on the NonStop system, as described in “Setting Up
a Backbone Messaging Network or Hub.”
•
Describe the UA and required MHS components in your MHS configuration, using
the MHS installation program and the Subsystem Control Facility (SCF).
Specifically, define the message stores and RS groups and identify the UA as an
application (APPL).
•
Provide addressing information for OSI/MHS on the system where the UA runs,
using tools provided for that implementation.
•
Specify the names of X.400 users, if necessary for a dedicated connection, using
SCF and possibly tools available for the other system.
•
Manage the MHS processes and databases.
