N
namelist. An MQSeries object that contains a list of
names, for example, queue names.
name service. In MQSeries on UNIX systems,
MQSeries for OS/2 Warp, and MQSeries for Windows
NT, the facility that determines which queue manager
owns a specified queue.
name service interface (NSI). The MQSeries interface
to which customer- or vendor-written programs that
resolve queue-name ownership must conform. A part of
the MQSeries Framework.
name transformation. In MQSeries on UNIX systems,
MQSeries for OS/2 Warp, and MQSeries for Windows
NT, an internal process that changes a queue manager
name so that it is unique and valid for the system
being used. Externally, the queue manager name
remains unchanged.
New Technology File System (NTFS). A Windows NT
recoverable file system that provides security for files.
nonpersistent message. A message that does not
survive a restart of the queue manager. Contrast with
persistent message.
NSI. Name service interface.
NTFS. New Technology File System.
null character. The character that is represented by
X'00'.
O
OAM. Object authority manager.
object. In MQSeries, an object is a queue manager, a
queue, a process definition, a channel, a namelist, or a
storage class (OS/390 only).
object authority manager (OAM). In MQSeries on
UNIX systems, MQSeries for AS/400, and MQSeries for
Windows NT, the default authorization service for
command and object management. The OAM can be
replaced by, or run in combination with, a
customer-supplied security service.
object descriptor. A data structure that identifies a
particular MQSeries object. Included in the descriptor
are the name of the object and the object type.
object handle. The identifier or token by which a
program accesses the MQSeries object with which it is
working.
off-loading. In MQSeries for OS/390, an automatic
process whereby a queue manager’s active log is
transferred to its archive log.
OPM. Original Program Model.
Original Program Model (OPM). The AS/400
Original Program Model. This is no longer supported
on MQSeries. It is replaced by the Integrated Language
Environment (ILE).
OTMA. Open Transaction Manager Access.
outbound channel. A channel that takes messages
from a transmission queue and sends them to another
queue manager. See also shared outbound channel.
output log-buffer. In MQSeries for OS/390, a buffer
that holds recovery log records before they are written
to the archive log.
output parameter. A parameter of an MQI call in
which the queue manager returns information when
the call completes or fails.
P
page set. A VSAM data set used when MQSeries for
OS/390 moves data (for example, queues and
messages) from buffers in main storage to permanent
backing storage (DASD).
PCF. Programmable command format.
PCF command. See programmable command format.
pending event. An unscheduled event that occurs as a
result of a connect request from a CICS adapter.
percolation. In error recovery, the passing along a
preestablished path of control from a recovery routine
to a higher-level recovery routine.
performance event. A category of event indicating
that a limit condition has occurred.
performance trace. An MQSeries trace option where
the trace data is to be used for performance analysis
and tuning.
permanent dynamic queue. A dynamic queue that is
deleted when it is closed only if deletion is explicitly
requested. Permanent dynamic queues are recovered if
the queue manager fails, so they can contain persistent
messages. Contrast with temporary dynamic queue.
persistent message. A message that survives a restart
of the queue manager. Contrast with nonpersistent
message.
ping. In distributed queuing, a diagnostic aid that
uses the exchange of a test message to confirm that a
message channel or a TCP/IP connection is
functioning.
platform. In MQSeries, the operating system under
which a queue manager is running.
