Filed:

Oct 20, 2003

Appl. No.:

10/687597

Inventors:

Julie Chen - San Jose CA, US
William James Franklin - San Ramon CA, US
John Marland Garth - Gilroy CA, US
John Richard Lyle - Morgan Hill CA, US
Frances Hwa Villafuerte - San Jose CA, US
Jay A. Yothers - Gilroy CA, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707205, 707 10, 707200

Abstract:

A base table and related auxiliary table spaces are reorganized concurrently via a database utility. The database utility determines which auxiliary tables are related to the base table and automatically includes their respective auxiliary table in the same invocation of the utility. The reorganization is performed via allocated shadow data sets. The original data sets are switched with the newly built shadow data sets including the LOB shadows.

International Classification:

G06F 17/30
G06F 17/00
G06F 12/00

US Classification:

707205, 707 1, 707100, 711171

Abstract:

A method and article of manufacture, implementing the method, allocates space for a dataset. The dataset has an initial area and zero or more additional allocated areas to provide space for storing the dataset. The size of a new additional area is determined. The new additional area is associated with a new area number, and the size of the new additional area is based on the new area number. Additional space for the dataset is allocated based on the size of the new additional area.

360/313000, 360/324100, 360/324200

Abstract:

Increasing the output signal from CPP GMR devices by increasing the read current has not previously been considered an option because it would make the device run too hot. This problem has been overcome by using, for the upper and lower leads, materials that differ significantly in their thermoelectric powers. Thus, when DC is passed through the device, from - to +TEP leads, hot and cold junctions are formed and heat is transferred from the micro-device into the leads, resulting in a net local cooling of the device which enables it to operate at higher power. For a GMR device, this translates to a larger output voltage, making it easier, more sensitive, and more reliable to use.
