Where to Look
•
The architecture of the local operations service and its support for multiple clients
and multiple associations with clients
To add a local user agent 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” earlier in this section.
•
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 LO processes and associated data, and
identify the user agent as an application (APPL). The collective name for an LO
process and its PDU store is LO group.
•
Specify the names of X.400 recipients to OSI/MHS.
•
Manage the MHS processes and databases.
To write an LUA or manage a configuration that includes one, you must be thoroughly
familiar with the X.400 P7 and ROSE protocols and aware of how OSI/MHS
implements the standards for those protocols. You must also know how to use Abstract
Syntax Notation 1 (ASN.1) for encoding and decoding protocol data. (Although you
will almost certainly use an ASN.1 tool, you will need to know ASN.1 to identify
interoperation problems and verify compliance with specific standards and agreements.)
Finally, if your LUA provides the functions of an access unit, you should be familiar
with the X.400 Recommendations with regard to access units.
Where to Look
In addition to the manuals and educational materials listed below, you are likely to need
information of the following types:
•
Copies of the CCITT X.400 series of Recommendations
•
Manuals for the C and possibly TAL programming languages, and NonStop
programming manuals
•
X.400 names and addresses (O/R names) of members of your user community
"About This Manual" lists and describes the X.400 Recommendations and related
documents, as well as the NonStop manuals you are likely to find most helpful.

contact your Compaq field representative.
Manuals and Media Guide
Table 1-8 includes Compaq manuals and educational media that help you write local
user agents and integrate them with OSI/MHS. Items are listed in one possible reading
Note. The P7 API is one of several interfaces you can use to integrate applications with
OSI/MHS. Table 1-10, in the description of “Integrating EDI Applications,” contrasts the
available interfaces.
