What You Need to Know
•
The Event Management Service (EMS)
•
NonStop Transaction Manager/MP (TM/MP)
•
NonStop SQL/MP (if you will use a message store)
•
The Compaq X.25 access method (X25AM) or the Compaq LAN Access
Method (TLAM), or both
•
Compaq OSI Application Services (OSI/AS)
•
Compaq OSI Transport Services (OSI/TS)
If you plan to use PS Mail or other Transfer applications across the network, the
Transfer information delivery system (including its X.400 gateway
), the NonStop
Transaction Manager/MP product, and related applications are also required.
Finally, if you want certain applications, such as management applications, to have
continuous availability and access to all of your backbone systems, it is wise to
install the Compaq Expand network software.
•
Install the message handling system (OSI/MHS) and its databases, including MHS
components required to support specific kinds of applications:
•
Message relay (MR) and reliable transfer service (RTS) processes to provide the
functions of an MTA (message relay and routing)
•
Message stores (MS) for use by RUAs and LUAs
•
Remote operations service (RS) processes for use by RUAs
•
Local operations service (LO) processes for use by LUAs
•
Gateway Interface Processes (GIP) if a system will include gateways based on
the Compaq Gateway Programmatic Interface (GPI)
All types of OSI/MHS processes can serve multiple users. You can also run
multiple instances of any process to provide fault tolerance and load balancing and
to increase throughput.
•
Use the Subsystem Control Facility (SCF) to complete the configuration—for
instance, to describe adjacent MTAs, routes, gateways, and X.400 recipients,
including message-store users—and to start the communications software and the
message handling system.
You can also define distribution lists (which let you use one name to address a
predefined set of recipients) and closed user groups (lists of users who may
communicate only with one another).
•
Install management applications, such as password server processes, to provide
security-related management services. Compaq provides a Master Password Server
(MPS) and programming interfaces for developing custom password servers.
Note. If you plan to operate OSI/MHS over TCP/IP rather than OSI transport protocols, you
also need the Compaq TCP/IP product. OSI/MHS links to TCP/IP through the RFC-1006
feature of OSI/TS.
