TS/MP 2.5 Pathsend and Server Programming Manual

Figure 2 Pathsend Interprocess Communication
Although you can obtain some information about ACS Subsystem processes through the PATHMON
process (by means of PATHCOM or SPI), ACS Subsystem processes are not managed as
PATHMON-controlled objects. For details about management of ACS Subsystem processes, see
the NonStop TS/MP 2.5 Release Supplement Manual.
Client/Server Capabilities
The RSC/MP product and the POET brings client/server capabilities to the Pathway environment
by allowing you to move requestor functions to a workstation. RSC/MP allows client programs
residing on a workstation to access Pathway server-classes in any of following ways:
• Through a Pathsend requestor provided by RSC/MP; this requestor works with the ACS
subsystem processes.
• Through a special intelligent device support (IDS) requestor supplied with RSC/MP; this
requestor works with the TCP provided in the Pathway/iTS product.
• Through an IDS requestor that you develop in the SCREEN COBOL language; this requestor
works with the TCP provided in Pathway/iTS.
RSC/MP also allows requestors 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, see the Remote Server Call (RSC) Programming Manual. For
information about POET, see 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
to run on NonStop systems, therefore providing these applications with the fundamental advantages
of NonStop systems.
