service-level agreements. Agreements between the operations group and the group's users
that specify the group's objectives, requirements, and standards.
Simple Network Management Protocol (SNMP). An asynchronous request/response
protocol (implemented in the Transmission Control Protocol/Internet Protocol (TCP/IP)
protocol suite) used for network management. In the SNMP management framework,
each managed node is viewed as having several variables. By reading these variables,
the managed node is monitored. By changing the value of these variables, the managed
node is controlled.
SLSA subsystem. See
SNAX/HLS. A tool that provides a general-purpose, high-level interface by which
NonStop™ Kernel application programs can communicate with intelligent SNA devices
and software products.
SNMP. See
Simple Network Management Protocol (SNMP).
SPOOLCOM. A spooler utility program that helps system operators monitor and maintain
the spooler and create and initialize spooler components.
spooler. A set of programs that acts as an interface between users (and user application) and
the print devices on a particular node.
spooler supervisor. A process that monitors and communicates with the other processes and
decides when and where to print jobs. Each spooler has one supervisor.
state. In Subsystem Control Facility (SCF) subsystems, one of the generally defined possible
conditions of an object with respect to the management of that object. Examples of
states are DEFINED, STARTED, and STOPPED.
structured file. A file designed to contain a database. Structured files are key-sequenced,
entry-sequenced, or relative files.
substate. Further information about the state of a device. The state and substate together
provide information about the current condition of a device or path to a device.
subsystem. (1) A secondary or subordinate system, usually capable of operating
independently of or asynchronously with a controlling system. (2) A program or set of
processes that manages a cohesive set of Subsystem Control Facility (SCF) objects.
Each subsystem has a manager through which applications can request services by
issuing commands defined by that subsystem.
Subsystem Control Facility (SCF). A utility program used to control a variety of
subsystems. For G-series systems, you can use SCF online to configure, control, and
display information about configured objects within SCF subsystems. SCF has been
enhanced to perform many of the functions performed on D-series systems by
DSC/COUP and PUP.
