H
handle. See connection handle and object handle.
hardened message. A message that is written to
auxiliary (disk) storage so that the message will not be
lost in the event of a system failure. See also persistent
message.
I
ILE. Integrated Language Environment
®
.
immediate shutdown. In MQSeries, a shutdown of a
queue manager that does not wait for applications to
disconnect. Current MQI calls are allowed to complete,
but new MQI calls fail after an immediate shutdown
has been requested. Contrast with quiesced shutdown
and preemptive shutdown.
inbound channel. A channel that receives messages
from another queue manager. See also shared inbound
channel.
in-doubt unit of recovery. In MQSeries, the status of a
unit of recovery for which a syncpoint has been
requested but not yet confirmed.
Integrated Language Environment
®
(ILE). The
AS/400 Integrated Language Environment. This
replaces the AS/400 Original Program Model (OPM).
.ini file. See configuration file.
initialization input data sets. Data sets used by
MQSeries for OS/390 when it starts up.
initiation queue. A local queue on which the queue
manager puts trigger messages.
input/output parameter. A parameter of an MQI call
in which you supply information when you make the
call, and in which the queue manager changes the
information when the call completes or fails.
input parameter. A parameter of an MQI call in which
you supply information when you make the call.
installable services. In MQSeries on UNIX systems,
MQSeries for OS/2 Warp, and MQSeries for Windows
NT, additional functionality provided as independent
components. The installation of each component is
optional: in-house or third-party components can be
used instead. See also authorization service, name service,
and user identifier service.
instrumentation event. A facility that can be used to
monitor the operation of queue managers in a network
of MQSeries systems. MQSeries provides
instrumentation events for monitoring queue manager
resource definitions, performance conditions, and
channel conditions. Instrumentation events can be used
by a user-written reporting mechanism in an
administration application that displays the events to a
system operator. They also allow applications acting as
agents for other administration networks to monitor
reports and create the appropriate alerts.
Interactive Problem Control System (IPCS). A
component of OS/390 that permits online problem
management, interactive problem diagnosis, online
debugging for disk-resident abend dumps, problem
tracking, and problem reporting.
Interactive System Productivity Facility (ISPF). An
IBM licensed program that serves as a full-screen editor
and dialog manager. It is used for writing application
programs, and provides a means of generating
standard screen panels and interactive dialogues
between the application programmer and terminal user.
IPCS. Interactive Problem Control System.
ISPF. Interactive System Productivity Facility.
L
linear logging. In MQSeries on UNIX systems,
MQSeries for OS/2 Warp, and MQSeries for Windows
NT, the process of keeping restart data in a sequence of
files. New files are added to the sequence as necessary.
The space in which the data is written is not reused
until the queue manager is restarted. Contrast with
circular logging.
listener. In MQSeries distributed queuing, a program
that monitors for incoming network connections.
local definition. An MQSeries object belonging to a
local queue manager.
local definition of a remote queue. An MQSeries
object belonging to a local queue manager. This object
defines the attributes of a queue that is owned by
another queue manager. In addition, it is used for
queue-manager aliasing and reply-to-queue aliasing.
local queue. A queue that belongs to the local queue
manager. A local queue can contain a list of messages
waiting to be processed. Contrast with remote queue.
local queue manager. The queue manager to which a
program is connected and that provides message
queuing services to the program. Queue managers to
which a program is not connected are called remote
queue managers, even if they are running on the same
system as the program.
locale. On UNIX systems, a subset of a user’s
environment that defines conventions for a specific
culture (such as time, numeric, or monetary formatting
and character classification, collation, or conversion).
The queue manager CCSID is derived from the locale
of the user ID that created the queue manager.
