table used to convert information from a file in an external system to correspond with the local system.
- A data source that is used by a lookup policy to mask data in another data source.
- A database table used to map one or more input values to one or more output values.
A user who is authenticated in the Enterprise Directory and searches for other users. IBM Security Access Manager for Enterprise Single Sign-On uses the lookup user to retrieve user attributes from the Active Directory or LDAP enterprise repository.
- A connectivity topology that connects a series of systems or expansion units together. Signals can travel in either direction for optimized performance. Redundancy is provided to each unit by treating the connection as a string when a failure occurs somewhere in the loop.
- A set of questions that are to be asked more than once. In a categorical loop, the number of times that the loop is to be iterated is controlled by the categories in a category list. For example, a set of questions can be asked for each product in a product list. In a numeric loop, the number of times that the loop is to be iterated is controlled by a numeric expression. See also slice.
- A sequence of instructions performed repeatedly.
- A closed unidirectional signal path connecting input and output devices to a system.
- A configuration of devices connected to the fabric by way of a fabric loop port (FL_port) interface card.
- The physical connection between a pair of device adapters in the ESS. See also device adapter.
A feature of the IBM 4300 Processor family that allows the attachment of a variety of SNA and non-SNA devices. To VTAM, these devices appear as channel-attached type 2 physical units (PUs).
An interface that bypasses unnecessary communications functions when the information is addressed to an entity within the same system. See also loopback test.
A test in which signals from a tester are looped at a modem or other network element back to the tester for measurements that determine or verify the quality of the communications path. See also loopback interface.
loopback virtual file system (LOFS)
A file system that is created by mounting a directory over another local directory, also known as mount-over-mount. A LOFS can also be generated using an automounter.
The logical procedure used by a loop port (L_port) to discover its environment. Loop initialization can be used to assign arbitrated loop physical addresses (AL_PAs), detect loop failure, or reset a node.
In SPL routines, an SQL identifier whose declaration immediately precedes an iterative statement, and whose name immediately follows the terminating END FOR, END LOOP, or END WHILE keywords. The EXIT label statement can transfer program control to the first executable statement that follows the last statement in the FOR, FOR LOOP, LOOP, WHILE LOOP, or WHILE loop that has the specified loop label.
An optimization that increases the step of a loop, and duplicates the expressions within a loop to reflect the increase in the step. This can improve instruction scheduling and memory access time.
loosely coupled analysis engine
An aggregate analysis engine whose component analysis engines do not run in the same address space, but each is remote from the others that make up the aggregate. See also analysis engine.
See level of service.
Pertaining to image transformation in which all of the data is retained. See also lossy.
Pertaining to image transformation in which some of the data is lost. See also lossless.
Lotus Domino for i5/OS (Domino for i5/OS)
The System i implementation of the Lotus Domino server. Lotus Domino for i5/OS is a full-function Domino server that follows the Domino architecture. The server software includes email, groupware, workflow, calendar and scheduling, and web server functions.
Lotus multibyte character set (LMBCS)
The format in which Notes stores all internal text, except file attachments and objects. As a result, any user can edit, forward, and mail documents and work with databases in any language.
Any object that is an instance of a Lotus-
