6760713, Jul 6, 2004

Filed:

May 3, 2001

Appl. No.:

09/849861

Inventors:

Harley A. Beier - San Martin CA
Dean Lynn Grover - Hollister CA
Claudia Si-man Ho - San Jose CA
Percy Tzu-jung Li - Morgan Hill CA
Vern Lee Watts - Los Altos CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1518

US Classification:

706 7, 706 52

Abstract:

A fuzzy data record pointer is utilized for identification of both a target file and a target data record within the target file. A target data record is accessed from a target file, selected from a set of N related files, utilizing a fuzzy data record pointer (âfuzzyâ, as used herein, means that the data record pointer need not be coincident with the actual data record address). A modulus for the data record pointer divided by N is computed. This modulus is used to select the target file. A data record address is computed for the target data record utilizing the data record pointer and modulus. In this manner a fuzzy data record pointer is utilized to determine both the target file from a set of N related files and the target data record to be accessed within the target file.

International Classification:

G06F 17/30

US Classification:

707204, 707200, 707202

Abstract:

An on-line reorganization facility (ORF) uses index data-spaces that point to other data-spaces, referred to as data data-spaces, to efficiently track and coordinate information about the data-elements in an original data-space operated upon by a reorganization process. A relative base address of a data-element in an index data-space can be derived from a relative base address of a data-element in an original data-space, and vice versa. An index data-space data-element contains a location of a data-element in a data data-space that tracks change information related to a corresponding data-element in the original data-space. Tracked changes are later applied to the newly reorganized data-space to assure consistency and integrity of the data. Tracked changes include the location in the original data-space where the change occurred and a flag indicting the type of change.

International Classification:

G06F 9/46

US Classification:

718102, 718103

Abstract:

A throttling specification is received by a computer task to direct the computer task's usage of critical computer resources, such as CPU cycles. The computer task comprises units of work, and the elapsed time of each unit of work is calculated as each unit of work completes. Upon the completion of one unit of work, a suspension time is calculated based at least partially on the throttling specification and the elapsed time corresponding to the completed unit of work. Prior to initiating the next unit of work for the computer task, the computer task is suspended for the calculated suspension time. In this manner, other important computing tasks operating in the computer system have access to critical computer resources during the suspension period. Even though the computer task may be given the highest possible priority to ensure a timely and predictable completion, total monopolization of critical computer resources is avoided.

International Classification:

G06F 17/30

US Classification:

707101, 707100, 707103 R

Abstract:

Methods and apparatuses are described that use index data-spaces that point to other data-spaces referred to as data data-spaces to efficiently associate temporary information with data-elements in a data-space. An original data-space is divided into data-elements of fixed size, based upon application requirements for the resolution at which temporary information is to be associated with data in the original data-space. The relative base address of data-elements in an index data-space can be ascertained from the relative base address of their corresponding data-element in an original data-space, and vice versa. Each index data-space data-element can be populated with a pointer to a data data-space data-element that can be populated with information relevant to the associated original data-space data-element. Index data-space and data data-space memory requirements are optimized to meet application requirements.

Abstract:

A method of reorganizing a database while concurrently providing access to the database for updates. In an exemplary embodiment of the method, an on-line reorganization facility (ORF) uses index data-spaces that point to other data-spaces, referred to as data data-spaces, to efficiently track and coordinate information about the data-elements in an original data-space operated upon by a reorganization process. A relative base address of a data-element in an index data-space can be derived from a relative base address of a data-element in an original data-space, and vice versa. An index data-space data-element contains a location of a data-element in a data data-space that tracks change information related to a corresponding data-element in the original data-space. Tracked changes are later applied to the newly reorganized data-space to assure consistency and integrity of the data. Tracked changes include the location in the original data-space where the change occurred and a flag indicting the type of change.
