System And Methodology For Performing Read-Only Transactions In A Shared Cache

View page
US Patent:
7822727, Oct 26, 2010
Filed:
Jul 2, 2004
Appl. No.:
10/710356
Inventors:
Steven T. Shaughnessy - Scotts Valley CA, US
Assignee:
Borland Software Corporation - Rockville MD
International Classification:
G06F 7/00
US Classification:
707703
Abstract:
A database system providing high performance database versioning is described. In a database system employing a transaction log, a method for restoring databases to a consistent version comprises steps of: providing a shared cache storing database blocks for use by multiple databases; for a read-only transaction of a given database, creating a cache view of the shared cache using the given database's transaction log, the cache view comprising particular database blocks of the shared cache that record a view of a particular version of the database at a given point in time; creating a shadow cache for storing any database blocks that overflow the cache view; and in conjunction with the cache view and the shadow cache, preserving a logical undo operation for the read-only transaction of the given database, so as to allow the given database to be restored to a transactionally consistent version.

US Patent:
8117174, Feb 14, 2012
Filed:
Sep 30, 2010
Appl. No.:
12/895706
Inventors:
Steven T. Shaughnessy - Scotts Valley CA, US
Assignee:
Borland Software Corporation - Scotts Valley CA
International Classification:
G06F 7/00
US Classification:
707704
Abstract:
A database system providing high performance database versioning is described. In a database system employing a transaction log, a method for restoring databases to a consistent version including creating a cache view of a shared cache and performing undo or redo operations on the cache view only when a log sequence number falls within a certain range.

US Patent:
20120158680, Jun 21, 2012
Filed:
Dec 29, 2011
Appl. No.:
13/340301
Inventors:
Steven T. SHAUGHNESSY - Scotts Valley CA, US
Assignee:
BORLAND SOFTWARE CORPORATION - Rockville MD
International Classification:
G06F 17/30
US Classification:
707703, 707E17005
Abstract:

System And Methods For Monitoring Functions In Natively Compiled Software Programs

US Patent:
60262354, Feb 15, 2000
Filed:
May 20, 1997
Appl. No.:
8/858612
Inventors:
Steven T. Shaughnessy - Scotts Valley CA
Assignee:
Inprise Corporation - Scotts Valley CA
International Classification:
G06F 945
US Classification:
395704
Abstract:
A development system having a monitor/profiler tool for monitoring functions in natively compiled software programs is described. According to the present invention, the monitor/profiler tool is constructed to work directly on a natively compiled software application which only have debugging info. Unlike prior approaches, the monitor/profiler tool does not require a special compile or link phase for the application under exam. The tool can monitor any function in software application which has debug info, thus relieving program developers from the burden of maintaining two ways of building an application. The developer can simply use the same executable for both development and function analysis.

Database Development System With Methods For Java-String Reference Lookups Of Column Names

View page
US Patent:
57874310, Jul 28, 1998
Filed:
Dec 16, 1996
Appl. No.:
8/767167
Inventors:
Steven T. Shaughnessy - Scotts Valley CA
Assignee:
Borland International, Inc. - Scotts Valley CA
International Classification:
G06F 1700
US Classification:
707100
Abstract:
A Java-based rapid application development (RAD) environment for creating applications providing named-based programmatic access to information from columns in databases is described. For increasing the efficiency by which named-based references to database columns are processed by application programs, the system provides methodology for rapid lookups of column names, using a reference cache storing 32-bit references to immutable strings (e. g. , Java strings). The reference cache is preferably constructed as a least-recently allocated cache, thereby allowing allocation to occur in a round-robin fashion, with the oldest item allocated being the first item bumped from cache when the cache overflows. Each cache entry stores a reference (e. g. , four-byte pointer or handle to a string) and an ordinal entry (i. e.

System And Methods For Data Field Management In A Computer Database System

View page
US Patent:
55617930, Oct 1, 1996
Filed:
Aug 18, 1993
Appl. No.:
8/109033
Inventors:
John G. Bennett - San Mateo CA
Steven T. Shaughnessy - Scotts Valley CA
Christopher W. Brumme - Boulder Creek CA
Assignee:
Borland International, Inc. - Scotts Valley CA
International Classification:
G06F 1730
US Classification:
395600
Abstract:
A system of the present invention includes a relational database management system (RDBMS). Methods are described for maintaining integrity between "design documents," which may be creating under different operating systems, and one or more information tables of the system. The system provides each field of a table with a unique ID ("field ID") for tracking the field regardless of restructuring changes which may be made to the table by various clients. Corresponding field IDs are stored with the fields of design documents, thereby permitting the system to maintain a link between a design document and its table. Upon a restructure of a table, the dependent design documents may be appropriately updated by their respective clients. Methods are also described for improved storage of free-form or "memo" data. In a preferred embodiment, memo data are stored in a separate file comprised of variable-length storage blocks.

System And Methods For Improved File Management In A Multi-User Environment

US Patent:
56921780, Nov 25, 1997
Filed:
Jul 16, 1996
Appl. No.:
8/682055
Inventors:
Steven T. Shaughnessy - Scotts Valley CA
Assignee:
Borland International, Inc. - Scotts Valley CA
International Classification:
G06F 1200
US Classification:
395608
Abstract:
A computer system having concurrently shared objects or resources is described. An exemplary embodiment includes a multi-user database management system having information tables and related objects stored in shared directories on a file server. A plurality of lock types, including directory lock, full lock, write lock, prevent full lock, and prevent write lock, are provided for controlling concurrent access. Methods are described for managing locks by creating a special lock file for each shared directory that is accessed. The lock file stores at least one logical lock file having locking or concurrency information specific to a family of related members. The logical lock file itself includes a plurality of entries for specifying concurrency information of associated family members. A shared object or resource is accessed according to the information retrieved from the corresponding logical lock file.
