NonStop TS/MP Provides monitoring for server processes in addition to linkage
between requesters and servers through the PATHMON process. It
provides an operations interface through PATHCOM. It also includes
the Pathsend API which allows NonStop requesters to be written in
any programming language to provide message control for client
processes running on other vendor’s hardware.
Pathway/iTS Provides support for traditional HP requester processes including
process pair protection for COBOL programs interpreted by the
terminal control process (TCP) and the COBOL programming
language, which supports transaction semantics.
Remote Server
Call/MP (RSC/MP)
Provides a function-call interface for a workstation-based client to
communicate with a server process. The interface includes support
for transaction semantics. Configuration options allow for alternate
routing. The Transaction Delivery Process (TDP) is a persistent
process that is the part of RSC/MP that runs on the HP server
system.
