conversational mode
conversational mode. (1) 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. (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. (1) 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. (2). The operation that restarts a Pathway/XM environment. This operation uses
the state information in the SuperCTL file and the configuration information in the
existing PATHCTL files for the PATHMON processes. The Pathway/XM environment
must have been previously started with a cold start operation. See also cold start
, state
information, SuperCTL file, and PATHMON configuration file.
Crossref cross-reference generator. A Compaq software tool on NonStop™ Himalaya
systems that produces a cross-referenced listing of selected identifiers—such as data
variables, statement labels, or subprograms—in an application program.
current configuration. The configuration of a Pathway/XM environment at the present time,
including any temporary online changes that have been made—for instance, with
CONTROL SERVER statements. See also initial configuration
.
current working directory. The OSS directory from which relative pathnames are resolved.
See also OSS pathname
and relative pathname.
D
database consistency. The state of a database in which items satisfy established criteria. For
example, an account balance must equal credits to the balance minus debits to the
balance. When the database satisfies these criteria, the database is considered to be
consistent. In general, a database is consistent when it is accurate and all changes
generated by transactions are complete. Database consistency is defined by the
application, which establishes the values and relationships of database fields and
records.
