NonStop Distributed
Computing
Environment (DCE)
Provides a development and execution environment with APIs for the
execution of DCE-compliant applications. DCE provides
interoperability with (and portability for) DCE-compliant multithreaded
applications on other computing platforms.
Refer to the DCE Application Programming Guide for details.
NonStop operating
system Open
System Services
(OSS)
Provides an environment with a command line interface and APIs for
the execution of POSIX-conformant or XPG4-compliant applications,
which provides portability between UNIX and HP NonStop operating
system platforms.
Refer to the OSS manuals for details.
NonStop Software
product set
Provides portability of application components between HP NonStop
operating system platforms and Windows NT Server platforms.
RSC/MP Provides a gateway and APIs that allow multithreaded transfers of
data among applications that use differing communications
protocols.
Refer to the RSC/MP Programming Manual for details.
