qualifier.
qualified job name
A job name and
its associated user name and a system-assigned job number. Contrast
with job name.
qualified logical link control (QLLC)
An
X.25 protocol that allows the transfer of data link control information
between two adjoining SNA nodes that are connected through an X.25
packet-switching data network. The QLLC provides the qualifier "Q"
bit in X.25 data packets to identify packets that carry logical link
protocol information. Contrast with enhanced logical link control
(ELLC) and physical services header
(PSH).
qualified name
The name of the
library containing the object and the name of the object. Contrast with
object name.
qualifier
In data processing, all
names in a qualified name other than the far right, which is called the simple
name.
quality of service (QOS)
In OSI, a
value that specifies certain performance characteristics of a service,
session, or link. In OSI Communications Subsystem, quality of service
is provided at the network layer.
quantified predicate
In DB2 UDB
for AS/400, a predicate that compares a value with a set of
values.
query
(1) A request to select and
copy from a file or files one or more records based on defined
conditions. For example, a request for a list of all customers in a
customer master file, whose balance is greater than $1000.
(2) The query management object that
is used to define queries against relational
data.
Query
The IBM licensed program
used to select, format, and analyze information from data files to produce
reports and other files.
query application
See
application.
query command
The name of an
action, and any associated parameters, that can be performed by query
management. The query commands include ERASE, EXIT, EXPORT, GET,
IMPORT, PRINT, RUN, SAVE, SET, and
START.
query command procedure
In query
management, a type of query procedure that contains a subset of the query
commands allowed in a query procedure. The query command procedure can
be used for initializing global
variables.
query definition
In Query,
information about a query that is stored in the system. The
system-recognized identifier for the object type is
*QRYDFN.
query instance
In query
management, a collection of system resources and a set of query commands
within an application program.
query management form
In query
management, the type name of the OS/400 object on the AS/400 system that is
comparable to the term form object as used for the Systems Application
Architecture (SAA) solution. The system-recognized identifier for a
query management form is *QMFORM.
query management object
In query
management, a collective term to describe any of the query management
objects: query, form, or
procedure.
query management procedure
The name
used in Query Management/400 to describe a source physical file member that
contains query procedure language
statements.
query management query
In query
management, the type name of the OS/400 object on the AS/400 system that is
comparable to the term query object as used for the Systems Application
Architecture (SAA) solution. The system-recognized identifier for a
query management query is *QMQRY.
Query Management/400
A function of
the OS/400 licensed program that is the AS/400 implementation of the SAA
solution for the Query common programming
interface.
query manager
The part of the
OS/2 operating system that handles the user's request for information
from an existing database.
query mode
In query management,
the processing mode associated with a query
instance.
queue
A list of messages, jobs,
files, or requests waiting to be read, processed, printed, or distributed in a
predetermined order.
queued call
A telephone call that
has been placed on hold and is waiting in the queue of telephone calls to be
serviced by a system resource (such as an ACD
group).
queue depth
In SNADS, the number
of distribution items on the distribution queue waiting to be sent. See
also send depth and send
time.
queue manager
(1) A system program
that provides queuing services to applications. It provides an
application programming interface so that programs can access messages on the
queues that the queue manager owns. See also local queue
manager and remote queue manager.
(2) In MQSeries, an MQM object
that defines the attributes of a particular queue
manager.
quick query
A query that is run
using only a file name and possibly some record selection specifications;
an undefined query.
QuickStep pad
A window containing
a variable number of buttons that can be clicked on with a mouse. Each
button can be assigned a macroinstruction that issues a predefined sequence of
keystrokes or commands.
quiesce
To become
inactive.
quiescing
In MQSeries, the state
of a queue manager prior to it being stopped. In this state, programs
are allowed to finish processing, but no new programs are allowed to
start.
Q.931
A CCITT
Recommendation that defines the network level (network layer) protocol for
integrated services digital network (ISDN). Q.931 is the
signalling protocol between the user and the network and provides the means
for systems or users to establish and end network connections across
ISDN.
Q.932
The CCITT
Recommendation that defines the generic procedures applicable for the control
of supplementary services at the user-network interface. These
procedures expand on the basic call-control functions defined in
Q.931. See also Q.931.
