TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

As shown in the figure, only server-class control information is passed to the LINKMON process;
the application data moves directly from the Pathsend requester process to the server process.
Figure 2 Pathsend Interprocess Communication
Although you can obtain some information about LINKMON processes through the PATHMON
process (by means of PATHCOM or SPI), LINKMON processes are not managed as
PATHMON-controlled objects. For details about management of LINKMON processes, refer to the
NonStop TS/MP System Management Manual.
Client/Server Capabilities
The RSC/MP product and the POET bring client/server capabilities to the Pathway environment
by allowing you to move requester functions to a workstation. RSC/MP allows client programs
residing on a workstation to access Pathway server classes in any of three different ways:
• Through a Pathsend requester provided by RSC/MP; this requester works with the LINKMON
process or the ACS subsystem processes.
• Through a special intelligent device support (IDS) requester supplied with RSC/MP; this
requester works with the TCP provided in the Pathway/iTS product.
• Through an IDS requester that you develop yourself in the SCREEN COBOL language; this
requester works with the TCP provided in Pathway/iTS.
RSC/MP also allows requesters to access Guardian processes directly. To facilitate access to
servers and Guardian processes, RSC/MP consists of multiple components within both the
workstation and NonStop environments.
The POET provides tools for developing RSC/MP clients for the Microsoft Windows environment.
These tools include a simplified programmatic interface, name mapping, and data conversion
mapping.
For information about RSC/MP, refer to the Remote Server Call (RSC) Programming Manual. For
information about POET, refer to the Pathway Open Environment Toolkit (POET) Programming
Manual.
Other Transaction Processing Environments
The TS/MP product serves as the foundation for open transaction processing on NonStop systems.
In addition to the Pathway environment, TS/MP supports the NonStop Tuxedo transaction processing
system. This product allows you to develop NonStop Tuxedo transaction processing applications
