Simple Network Management Protocol (SNMP)
•
Write scripts to customize the interface. For example, you can control window
placement on the screen, assign each window to a process, decide what text is sent
to a process, and determine how the output from a process is displayed.
Simple Network Management Protocol (SNMP)
The SNMP subsystem lets operations personnel who operate multiplatform networks
(for example, networks containing Integrity S2 systems, Ungermann-Bass products, and
NonStop systems) configure Tandem NonStop operating system-based subsystems to be
monitored and controlled from network management workstations that comply with
SNMP. SNMP defines a standard way of managing devices from multiple vendors on a
TCP/IP-based network.
Subsystem Control Facility (SCF)
For G-series systems, you use the Subsystem Control Facility (SCF) to configure,
control, and display information about configured objects within SCF subsystems. Each
SCF subsystem responds to and processes SCF commands that affect that subsystem.
The processes created in these SCF subsystems are persistent; if the system comes
down, these processes are automatically restarted as soon as the system is loaded. Super-
group users (255,n) can use the SCF command-line user interface to make configuration
changes from any connected terminal.
When you install a G-series release on a Himalaya S-series server, the $SYSTEM disk
and a few other initial system-load processes are preconfigured, and SYSGENR uses the
CONFTEXT file to establish some system attributes to all processors. Then you finish
the system configuration by using SCF. You can use SCF to perform these tasks:
•
Add, alter, or delete objects, including disk and tape devices, I/O processes, and
generic processes
•
Obtain configured or current information about supported objects
•
Alter some system variables that are configured on D-series systems by SYSGEN
•
Measure network traffic
Because configuration changes are made online using SCF, they take effect as soon as
the affected objects are started (with the SCF START command). For subsystems that
are new for G-series systems, these changes are permanent; they persist through
processor and system loads (unless you load the system using a different configuration
file). For older SCF subsystems that are controlled on G-series systems by the ServerNet
WAN subsystem, configuration changes are not permanent; you must reimplement them
if the system or a processor goes down.
Subsystem Programmatic Interface (SPI)
SPI provides a standard set of interfaces for building management applications.
Application developers can use SPI to create management applications that will help
your staff manage systems and networks, eliminate repetitive tasks, and reduce the
chance of human error.
