System And Methodology For Database Migration Between Platforms

View page
US Patent:
7293040, Nov 6, 2007
Filed:
Feb 28, 2005
Appl. No.:
10/906652
Inventors:
Katsunori Terada - Dublin CA, US
Assignee:
Sybase, Inc. - Dublin CA
International Classification:
G06F 17/30
US Classification:
707102
Abstract:
A system and methodology for database migration between platforms is described. In one embodiment, for example, a method is described for migrating a database across platforms having different byte order formats (e. g. , big-endian and little-endian), the method comprises steps of: when the database is loaded on a given platform, determining whether the database requires conversion to match the byte order format of the given platform; identifying particular portions of the database to be converted if the database is determined to require conversion; and converting the particular portions of the database to the byte order format of the given platform.

US Patent:
20100257181, Oct 7, 2010
Filed:
Apr 1, 2009
Appl. No.:
12/416527
Inventors:
Panfeng ZHOU - Pleasanton CA, US
Katsunori TERADA - Pleasanton CA, US
Yanhong WANG - Dublin CA, US
Assignee:
Sybase, Inc. - Dublin CA
International Classification:
G06F 12/00
G06F 7/00
G06F 12/10
US Classification:
707747, 711216, 711170, 711206, 707E17045, 711E12001, 711E1206, 711E12002
Abstract:
Aspects for achieving efficient data access to data elements in a relational database management system are provided. In a computer-implemented method aspect, the efficient data access occurs by establishing a hash table for data elements of a database in a predetermined continuous space of allocated storage, and optimizing utilization of the hash table during database query operations through linear hashing, wherein extension of the hash table occurs automatically to increase a number of pages in the hash table without discernible interruptions of data access to the data elements.

US Patent:
20140188821, Jul 3, 2014
Filed:
Dec 28, 2012
Appl. No.:
13/730207
Inventors:
Panfeng ZHOU - Dublin CA, US
Katsunori TERADA - Dublin CA, US
Yanhong WANG - Dublin CA, US
International Classification:
G06F 17/30
US Classification:
707693
Abstract:
Methods, systems, and computer program products are provided to manage a database system. The method includes locking during a database system idle time access by the database system to a data page of a data allocation unit, compressing during the database system idle time a data stored in the locked data page, and recording during the database system idle time an indication that the compressed and locked data page includes free storage space, wherein unlocked data pages of the data allocation unit are accessible by the database system during the compressing of the data stored in the locked data page. Thus, the data page may be compressed during idle time and the space freed therein may be used during a subsequent run time without the need for a reorganization of the data pages within the corresponding table (as in, for example, operation of a reorg+rebuild SQL command combination).
