taining copies of the tie-up records written to forward recovery logs. It provides a summary of which recoverable Virtual Storage Access Method (VSAM) data sets the Customer Information Control System (CICS) has used, when they were used, and to which log stream the forward-recovery log records were written. The log of logs is written by CICS to provide information to forward recovery programs such as CICS VSAM Recovery (CICSVR).
- To connect to a computer system or network.
- In SNA products, to initiate a session between an application program and a logical unit (LU).
An ETO descriptor that provides information required by IMS to build terminal-related control blocks. See also ETO descriptor.
In VTAM, a subset of session parameters specified in a logon mode table for communication with a logical unit (LU). See also session parameter.
See log recording data set.
- A predefined structure into which the log data is formatted. Records have a specific size and format, and contain a certain set of related information. A log record can be identified by its log sequence number (LSN).
- A set of data that is treated as a single unit in a log file.
- A discrete piece of information that describes an event that occurs in a system. For example, a record of an update to a database performed during a unit of work (UOW) is written after the log tail of the active log.
- An entry in a log view that consists of properties and their values. A log record does not contain instances of other log records but has nested levels of entries or children.
log record sequence number (LRSN)
A unique identifier for a log record that is associated with a data sharing member. DB2 for z/OS uses the LRSN for recovery in the data sharing environment. See also log sequence number.
In an RSR environment, the component of the tracking subsystem that receives log data from active subsystems, stores the data in tracked log data sets, and routes the log records to tracking components.
- See log record identifier.
- In DB2 for Linux, UNIX, and Windows, an ordered identifier for a log record. The log sequence number is used by recovery operations. See also log record sequence number.
The process of copying whole log files to a standby machine, either from an archive device or through a user exit program running against the primary database. See also high availability disaster recovery.
A set of log files that is associated with a member or the result of merging the logs of multiple members. See also log stream merge.
log stream merge
The process of ordering log records from the log streams of multiple members so that the merged log stream is in chronological order. See also log stream.
In Tivoli software, a utility that filters logs stored in a common XML format, and generates output in text or HTML format for easier viewing. See also Tivoli common directory, Tivoli XML log format.
The year that a document was filed. Used to identify a printed document number. For example, 88-0001, where 88 is the log year and 0001 is the sequence number. All documents filed in 1988 have a log year of 88.
Up to a full-screen description of a field, record format, or file. Long comments are typed when the field, record format, or file is created or changed, and displayed either from IDDU or Query.
See long description.
- An extended description of a term in a business glossary that fully defines the term. See also short description.
- An HTML attribute used within the image element, frame element, or iframe element. It associates an image description with the code that places the image in the web page. See also alternative text.
A variable-length identifier that includes three parts: An encoding scheme identifier. One or more coded graphic character set global identifiers. Each coded graphic character set global identifier is a concatenation of a graphic character set global identifier and a code page global identifier. Additional coding-related required information.
