 an input device that provides coordinate data; for example, a mouse, tablet, or thumb wheel.
- An XML element that supplies an Xpointer reference to the taxonomy schema element definitions that uniquely identify each concept.
- A page number or link leading from an index entry to the location of specific information in a topic.
- The process by which integrity of data is ensured by preventing more than one user from accessing or changing the same data or object at the same time.
- A means of serializing a sequence of events or serializing access to data.
- A means of preventing uncommitted changes made by one application process from being perceived by another application process and for preventing one application process from updating data that is being accessed by another process. A lock ensures the integrity of data by preventing concurrent users from accessing inconsistent data.
- A function on mobile devices that prevents the keypad or touchscreen from responding to interactions until a valid unlock sequence is entered.
- To temporarily restrict resources to provide protection from concurrent users of the system.
- To set a volume or snapshot as unwritable (read-only).
- A function that prevents data being entered into cells whether by typing or through a D-link.
- A mechanism with which a resource is restricted for use by the holder of the lock.
A dimension to which new categories cannot be added. When processing data sources, any records which refer to values for this dimension that do not already exist as categories are ignored.
A level in a dimension to which new categories cannot be added. When processing data sources, any records which refer to values for this level that do not already exist as categories are ignored.
The response that occurs when the number of locks issued for one agent exceeds the limit specified in the database configuration; the limit is defined by the maxlocks configuration parameter. During a lock escalation, locks are freed by converting multiple locks on rows of a table into one lock on a table. This process is repeated until the limit is no longer exceeded.
lock manager domain
Major component of CICS that provides locking and associated queueing for CICS resources. Before using these facilities, a resource must add a named lock for itself. This lock can then be requested as either exclusive or shared. If an exclusive lock is obtained, no other task many obtain the lock with that name; if a shared lock is obtained, multiple tasks may obtain that lock.
lock sequence number (LSN)
A unique number, issued sequentially, given to a database resource to identify that it is in use (locked) by a requestor. A locked resource cannot be used until the current requestor has finished using it.
- The state set by actuating a lock key, singly or in combination with a qualifier key (see ISO/IEC 9995-1).
- A condition defined for an object that determines how it is locked, how it is used (read or write), and whether the object can be shared (used by more than one job).
See loopback virtual file system.
- A record of events.
- A collection of records that sequentially describes the events that occur in a system.
- In WebSphere MQ, a file recording the work done by queue managers while they receive, transmit, and deliver messages, to enable them to recover in the event of failure.
- In Backup, Recovery, and Media Services, a history of backup, archive, recovery, and media management operations. A log can be displayed online or printed.
- A file used to record changes made in a system.
- To record. For example, to record all messages on the system printer.
- A collection of messages or message segments placed in an auxiliary storage device for accounting or data collections purposes.
Log and Trace Analyzer tool
The core technology of the IBM Autonomic Computing initiative that defines the interfaces for logging and tracing, providing a central point of interaction with multiple data sources.
