sktop computer, workstation, or mobile computer that has IBM Director Agent installed. The function of a Level-2 managed system varies depending on the operating system and hardware.
- A sorting comparison in a multilevel sorting algorithm that considers only the case in characters, such as the difference between a and A. Punctuation is typically ignored. See also case weight, level 4, level n.
- See packet level.
A specific piece of information stored about each member of a level. For example, the color attribute could be used to store the color of a product. Some attributes can have special significance, such as when the attribute contains the business key for the member.
A function that compares the record level identifiers of a file to be opened with the file description that is part of a compiled program to determine if the record format for the file changed since the program was compiled.
A function that must be performed but that needs to be performed by only one processing unit. Level functions include backing up the control data sets (CDSs), backing up migrated data sets, deleting expired dump copies, moving backup versions from level 1 volumes to backup volumes, migration cleanup, and level-1-to-level-2 migration. See also demotion, promotion.
- In COBOL, two alphabetic characters (FD or SD) that identify the type of file description entry.
- In RPG, two characters (L0 through L9 and LR) that control calculation and output processing during total time.
level n (Ln)
A sorting comparison in a multilevel sorting algorithm that considers only format characters or other tie-breaking characters that are not base letters, case, accents, or punctuation. See also level 1, level 2, level 3, level 4.
In COBOL, a numeric character (1 through 9) or a 2-character set (01 through 49, 66, 77, 88) that begins a data description entry and establishes its level in a data hierarchy. Level-numbers 66, 77, and 88 identify special properties of a data description entry.
level of isolation
See isolation level.
level of service (LOS)
A qualitative measure used in the transportation industry by traffic engineers to determine the effectiveness of elements of a transportation infrastructure. This measure describes the operational conditions of traffic as defined in the Highway Capacity Manual.
level one data sharing
For data entry database (DEDB) areas, a method of data sharing in which Database Recovery Control (DBRC) can authorize only one subsystem to update the database and multiple subsystems that are not required to be protected from incomplete changes made by the updater to read it, or it can authorize multiple subsystems to read the database. See also level three data sharing.
level three data sharing
A method of data sharing in which Database Recovery Control (DBRC) and one internal resource lock manager (IRLM) can concurrently authorize and protect multiple subsystems on the same z/OS system for updating or reading the database. See also level one data sharing, level two data sharing.
level two data sharing
A method of data sharing in which Database Recovery Control (DBRC) and one internal resource lock manager (IRLM) can concurrently authorize and protect multiple subsystems on the same z/OS system for updating or reading the database. See also level three data sharing.
The process by which a stream of characters is grouped into a series of lexical items, or tokens, and all available dictionary data is associated with the lexical items. Lexical analysis comprises three separate steps: segmentation, normalization and annotation. See also parsing.
lexical parsing item (LPI)
In lexical analysis, a unit in the lexical representation of text. A lexical parsing item contains annotations or gloss information to be associated with the range in the surface text. See also token.
The portion of a program or segment unit in which a declaration applies. An identifier declared in a routine is known within that routine and within all nested routines. If a nested routine declares an item with the same name, the outer item is not available in t
