mation needed to monitor the use of log files (for example, their size and location, and the name of the next available file).
- A file that records actions and commands.
- A text file that records the execution of a fact build, dimension build, or JobStream.
- The file where the log of events is recorded.
- In WebSphere MQ on UNIX and Linux systems, and WebSphere MQ for Windows, a file in which all significant changes to the data controlled by a queue manager are recorded. If the primary log files become full, WebSphere MQ allocates secondary log files.
An operator station task that requires a terminal and a logged-on user. See also autotask.
- A functional unit that records events and physical conditions, and usually the time the entry was logged.
- A named and stateful object with which the user code interacts and that logs messages for a specific system or application component.
- A program that enables a user entity to log in (for example, identify itself, its purpose, and time of entry) and log off with the corresponding data. This enables the appropriate accounting procedures to be carried out in accordance with the operating system.
- A component that prepares log statements to be written to console or log file. See also appender.
An agent that programmers can create in order to write data (for example Java primitives, objects, or predefined logging structures) to one or more output sources (for example text or XML), for an application under test.
- A value that controls which events are written to the log by event severity.
- A preference setting that specifies the number of entries and the amount of detail generated by various loggers.
- A value that controls which events are processed by Java logging.
- The instructions in an application arranged in a prescribed order to solve a problem.
- The systematized interconnection of digital switching functions, circuits, or devices.
Specialization of an architecture through the addition of constraints that enable verification of consistency and validity for the architecture's components, relationships and their respective types.
- A path over which data flows between the network and the receiving hardware (processor, memory, or storage).
- In X.25 communications, a means of two-way simultaneous transmissions across a data link, comprising associated send and receive channels. A logical channel can represent the path that data travels from its origin to the network or from the network to its destination.
- In a packet-switching data network, a path over which data flows between the network and the sending or receiving data terminal equipment.
logical channel subsystem (LCSS)
A channel subsystem structure that provides channel path and subchannel controls for configuring from one to four channel subsystem images. Each channel subsystem image can be configured with up to 256 channel paths, and each logical partition has access to one channel subsystem image.
logical character delete symbol
In VM, a special editing symbol, normally the AT (@) sign, that causes CP to delete it and the immediately preceding character from the input line. If many delete symbols are typed in consecutively, that same number of preceding characters are deleted from the input line. The value may be redefined or unassigned by the installation or user.
In a database, a pointer segment that establishes an access path between its physical parent and its logical parent. It is a physical child of its physical parent; it is a logical child of its logical parent.
A claim on a logical partition of a nonpartitioning index. See also claim.
logical control unit (LCU)
See control-unit image.
A database composed of one or more physical databases arranged in a hierarchical structure based on relationships among data segments. The structure of a logical database can be different from the physical structure of the data. See also physical database.
logical database record
In a database, a set of hierarchically related segments of one or more segment types. As viewed by the application program, the logical databas
