Filed:

Oct 13, 2010

Appl. No.:

12/904026

Inventors:

Stephanie H. Lee - Saratoga CA, US
David L. Levish - San Jose CA, US
Ronald E. Parrish - Santa Cruz CA, US

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION - Armonk NY

International Classification:

G06F 17/30

US Classification:

707822, 707E17009

Abstract:

Provided are techniques for using a series of compare and swap operations to assign a Relative Byte Address (RBA) and a Logical Record Sequence Number (LRSN) to a log record. One or more log buffers for storing the log record are identified, and the log record is moved to the one or more log buffers.

Appl. No.:

8/688116

Inventors:

Steven Victor Kauffman - San Jose CA
Lara Marie Lewis - Campbell CA
Ronald Elliott Parrish - San Jose CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1730

US Classification:

707200

Abstract:

The present invention is directed to a method and apparatus for supporting large digital objects. More particularly it relates to a client/server library system in which a large digital object is divided into smaller pieces which are stored in the client/server library system. By dividing the large digital object into smaller pieces, system limitations regarding object size are avoided. In one embodiment of the present invention the pieces are stored as files of variable size. Moreover, the pieces can be stored on separate object servers which can be located remotely from one another.

US Classification:

Abstract:

An object management system for storing persistent object oriented objects, includes an object vault, a structural type manager and a digital library. The object vault is connected to the structural type manager and the digital library is connected to the structural type manager. An application program is connected to the object vault. Objects to be stored are represented as a Key Value Dictionary (KVD) in which attributes, or metadata, relating to the objects are stored as key-value pairs. Objects are categorized as having different structural types in which certain attributes for objects having the same structural type are cataloged to facilitate indexing and searching for the objects. The structural type manager maintains a mapping between structural types and a subset of keys for the structural types as well as corresponding database references for cataloging the object attributes. Also disclosed is a method of storing objects in the digital library where the corresponding database references for the subset of keys are retrieved from the structural type manager.
