About This Manual
This manual contains information for programmers developing applications to manage a
Subsystem Control Point (SCP) process using the Subsystem Programmatic Interface
(SPI). It also contains a general discussion of tracing that is relevant to any subsystem
that supports tracing. Information describing D-series and G-series SCP processes is
included, as well as listings of obsolete information from older SCP processes.
SCP processes were originally released as part of Compaq’s Distributed Systems
Management (DSM) environment for D-series systems, and this manual assumes you
are familiar with these related manuals:
•
Introduction to Distributed Systems Management (DSM) (D-series only)
•
Distributed Systems Management (DSM) Manual (D-series only)
•
SPI Common Extensions Manual
•
EMS Manual
For information on the language used to define tokens and related data elements, see the
Data Definition Language (DDL) Reference Manual.

Section 1, Introduction summarizes the role of SCP processes in the Distributed
Systems Management (DSM) architecture and gives an
overview of changes prompted by the D-series Guardian
operating system.
Section 2, Communicating
With an SCP Process
describes how to start, open, and stop an SCP process.
Section 3, SPI
Programming
Considerations for SCP
describes how SCP processes handle SPI messages and
summarizes the differences between C-series and D-series SCP
processes.
Section 4, Common
Definitions
lists ZSCP, ZCOM, and ZTRC data definitions that
management applications use when managing SCP processes.
Section 5, Commands and
Responses
describes the SPI commands and responses supported by SCP
processes.
Section 6, Event Messages describes the event messages generated by SCP processes.
Appendix A, Errors describes errors reported by SCP processes.
Appendix B, Tracing describes how to start, modify, and stop a trace.
