SERVER object
SERVERCLASS_DIALOG_BEGIN_, and SERVERCLASS_DIALOG_SEND_
procedures perform server-class send operations. See also SEND operation.
SERVER object. A definition of a server class within the configuration of a PATHMON
process.
service. A function performed by a server process or program on behalf of a requester or
client. A server can perform one or several services. The concept of a service is built
into the design of the BEA TUXEDO system and the NonStop TUXEDO system; for
these products, a service is a module of application code that carries out a service
request.
simple token. In the Subsystem Programmatic Interface (SPI), a token consisting of a token
code and a value that is either a single elementary field, such as an integer or a character
string, or a fixed (nonextensible) structure. See also extensible structured token and
token (definition 2).
single-threaded. A programming model that provides a single thread of control within a
program. For example, a single-threaded server handles only one request at a time and
must complete that request before accepting another. See also thread and multithreaded.
special register. A data item defined by the SCREEN COBOL compiler, rather than
explicitly in the program. Each special register has a particular purpose and should be
used only as defined. The SCREEN COBOL language defines a different set of special
registers from those defined by the standard COBOL language.
SPI. See Subsystem Programmatic Interface (SPI).
static server. A server process that the PATHMON process creates when a START SERVER
command is issued. The PATHMON process starts the number of static servers defined
by the NUMSTATIC attribute for the server class. See also dynamic server.
Structured Query Language (SQL). A relational database language used to define,
manipulate, and control databases.
subsystem. In the context of the Subsystem Programmatic Interface (SPI) and the Event
Management Service (EMS), a process or collection of processes that gives users access
to a set of related resources or services. A subsystem typically controls a cohesive set of
objects. The Pathway subsystem includes PATHMON processes, TCPs, and all other
components of the PATHMON environment.
subsystem ID. In management applications, a data structure that uniquely identifies a
subsystem. The subsystem ID is specified in SPI commands to identify the target
subsystem, and in EMS event messages to identify the source of the event message.
The Pathway subsystem ID applies to all components of the PATHMON environment,
including PATHMON processes and TCPs.
Subsystem Programmatic Interface (SPI). A set of Guardian procedures, message formats,
and definition files that allows management applications to communicate directly with
