Subsystem Control Point (SCP)
Facility (SCF) Reference Manual describes the general features, syntax, and
semantics of SCF. The OSI/MHS SCF Reference Manual provides the subsystem-
specific syntax and semantics.
Subsystem Control Point (SCP)
SCP is an intermediate process between SCF and the OSI/MHS subsystem. It
provides security by restricting access to certain commands and provides tracing
support for OSI/MHS.
SCP is opened automatically by SCF. The SCP also supports management
programming interfaces based on the Subsystem Programmatic Interface (SPI),
allowing you to write applications to control and monitor OSI/MHS and other
communications products. Management applications have available to them the same
range of functions available through SCF.
For more details about SCP, see the Subsystem Control Facility (SCF) Reference
Manual and the SCF Reference Manual for SCP. For information about writing
management applications to control OSI/MHS, see the OSI/MHS Management
Programming Manual.
Event Management Service (EMS)
EMS provides event collection, event logging, and event distribution facilities for
OSI/MHS.
The OSI/MHS manager and subsystem processes detect significant events, generate
event messages, and send them to an EMS collector, which logs the messages. You
can view all or selected event messages reported to EMS. You can write filters to filter
event messages for selective printing or display on the operator console. You can use
information retrieved from EMS to monitor your OSI/MHS subsystem and to recognize
critical problems. For a description of the event messages that OSI/MHS generates,
see the OSI/MHS Management Programming Manual.
Most OSI/MHS events—those that have bearing on the operational status of
subsystem processes or that signify errors—are reported, by default, to the system-
wide EMS collector, $0; you can specify an alternate collector when you run the MHS
manager process. Events related to accounting and message tracking are also
reported, by default, to the system-wide collector, but most system managers choose
to specify an alternate collector.
The event messages that the OSI/MHS subsystem can issue are described in the
Operator Messages Manual. The tokens contained in each message are described in
the OSI/MHS Management Programming Manual. For general information about how
an application obtains event messages from a subsystem, see the EMS Manual.
