General User Gateway
2. The RTS writes the message to the PDU store.
3. The RTS notifies the MR process about the completed message.
4. The MR process reads, decodes, and delivers the message to an entry manager
process in the Transfer X400 gateway.
5. The MR process sends an entry (that includes the PDU ID) to the message queue
in the queue file.
6. The importer process receives the MESSAGE queue entry and begins to process
the PDU.
7. The importer process retrieves data from the PDU store.
8. The importer process translates the data for Transfer and writes the data to the
Transfer database.
General User Gateway
Another gateway to the OSI/MHS subsystem is the general user gateway. You can
configure as many as 16 general user gateways for an OSI/MHS subsystem. You
develop a gateway by using the OSI/MHS Gateway Programmatic Interface (GPI); you
define the gateway to the OSI/MHS subsystem through the GATEWAY object and the
APPL object in SCF.
The GPI explicitly supports interpersonal messaging (IPM) and electronic data
interchange (EDI) content types.
One type of GPI gateway is a P1 user exit gateway, which allows your application to
receive incoming messages directly from the RTS process. Your application can
process the message and optionally resubmit it to OSI/MHS for routing. You can define
only one P1 user exit gateway in an OSI/MHS subsystem.
For more information about the GPI, see the OSI/MHS Gateway Programmatic
Interface (GPI) Programming Guide and the OSI/MHS Gateway Programmatic
Interface (GPI) Reference Manual.
P7 API Interface
The local operations service (LO) group provides an interface from a local user to a
user mailbox in a message store. The LO group implements a local service analogous
to the Remote Operations Service Element (ROSE) protocol. The P7 Application
Programmatic Interface (P7 API) allows a TAL or C application to access an MS
through the LO group.
For more information about the P7 API interface, see the OSI/MHS P7 Application
Programmatic Interface (P7 API) Manual.
