TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

configured TERM
object
A TERM object that is explicitly configured with an ADD TERM command. Such a TERM object
exists until it is explicitly deleted. Names of configured TERM objects begin with a letter. See also
temporary TERM object and TERM object.
consistency. See database consistency.
context Information required by a server to process the current request in an exchange of multiple request
and reply messages: for example, identification of the last item processed. See also context-free
server and terminal context.
context sensitivity The ability of a requester to exchange a series of multiple request and reply messages (that is, a
dialog) with a particular server process. See also contextsensitive server and dialog.
context-free server A server that does not retain any information about the processing of previous requests. A
context-free server accepts a single message from a requester, performs the requested tasks, and
issues a single reply to respond to the requester. After the reply message is issued, the server
retains no information, or context, that can be used in subsequent requests. In general, context-free
servers are relatively simple to program and can be restarted quickly, but they require the requester
to pass context information to the server on each request. Servers handling requests from Pathsend
requesters can be either context-free or context-sensitive, but servers servicing requests from
SCREEN COBOL requesters must be context-free. A contextfree server is analogous to a NonStop
Tuxedo request and response server. NonStop subsystems are context-free servers; therefore,
management applications using the Subsystem Programmatic Interface (SPI) to communicate with
NonStop subsystems must pass back context information in continuation requests. See also context,
context-sensitive server, and Subsystem Programmatic Interface (SPI).
context-sensitive
server
A server that retains information about the processing of previous requests. A context-sensitive
Pathway server can engage in a multiplemessage communication, or dialog, with a requester.
Because context-sensitive servers must maintain message context for the dialog, they are more
complex to program than context-free servers. They typically have longer restart times because
they must recover the requester context. See also context and context-free server.
conversation See dialog.
conversational
mode
A terminal operating mode in which data is read from the terminal and displayed on the
terminal screen one line at a time. See also block mode and intelligent mode.
1.
2. The mode of communication that enables an ongoing dialog between a client (or requester)
and a server. Data is sent and received in an iterating fashion without return to the transaction
monitor until the application dialog is completed. Multiple messages can be exchanged
between the client and server participating in the communication. See also conversational
server.
conversational
model
A model for requester-server communication that enables an ongoing dialog between a client (or
requester) and a server. Multiple messages can be exchanged between the client and server
process before control is returned to the transaction monitor. See also request/response model
and conversational server.
conversational
server
A server that offers conversational services and can participate in a conversation, or dialog, with
a client; that is, a context-sensitive server. See also conversational mode (definition 2),
request/response server, and context-sensitive server.
cool start The operation that restarts a PATHMON environment, using the information in an existing
PATHMON configuration file (PATHCTL file). The PATHMON environment must have been
previously started with a cold start operation. See also cold start.
Crossref
cross-reference
generator
A HP software tool that produces a cross-referenced listing of selected identifiers—such as data
variables, statement labels, or subprograms—in an application program.
current working
directory
The OSS directory from which relative pathnames are resolved. See also OSS pathname and
relative pathname.
Data Definition
Language (DDL)
The set of data definition statements within the Structured Query Language (SQL).1.
2. An HP product for defining data objects in Enscribe files and translating object definitions
into source code.
data integrity The condition of a database when its data values are accurate, valid, and consistent according
to rules established for changing the database. See also database consistency.
