service
service. A set of primitives (operations) that a layer provides to the layer above it. The
service defines what operations the layer can perform on behalf of its users but not how
these operations are implemented. A service relates to an interface between two layers:
the lower layer is the service provider, and the upper layer is the service user. Compare
protocol
.
Service Advertising Protocol (SAP). A Novell protocol that enables service nodes, such as
file and print servers, to register their services and addresses in Server Information
Tables. Clients can then query these tables for available services and their Internetwork
Packet Exchange (IPX) addresses.
session. For a management application, the period during which an application can issue
commands to a subsystem.
SLSA subsystem. See ServerNet LAN systems access (SLSA) subsystem
.
SMB. See Server Message Block (SMB)
.
SNAP. See Subnetwork Access Protocol (SNAP)
.
socket. For Berkeley Software Distribution (BSD) software, an endpoint for communications
created by the socket or socket_nw2 function calls.
socket number. For NonStop™ IPX/SPX, the unique port identifier portion of the network
address, node address, and port identifier combination that makes up an IPX address. A
Berkeley Software Distribution (BSD) Internet port is the equivalent of a NonStop™
IPX/SPX socket number.
SPX. See Sequenced Packet Exchange (SPX)
.
SQL. See Structured Query Language (SQL)
.
SSID. See subsystem ID (SSID)
.
START. A sensitive command
that starts a NonStop™ IPX/SPX object.
STARTED. A summary state that indicates that an object
is running and is able to accept user
requests.
STARTING. A summary state that indicates that an object
is being initialized and is
attempting to start.
STATS. A nonsensitive command
that returns statistical information about a specified object.
STATS is sensitive when issued with the RESET option.
STATUS. A nonsensitive command
that returns status information about a specified object.
STOP. A sensitive command
that terminates the operation of a specified object in an orderly
manner.
