Filtered Remote Journal

View page
US Patent:
8239390, Aug 7, 2012
Filed:
Feb 26, 2010
Appl. No.:
12/713821
Inventors:
Bruce W. Hansel - Rochester MN, US
Margaret E. Levering - Rochester MN, US
Chad A. Olstad - Rochester MN, US
David F. Owen - Rochester MN, US
Donald F. Zimmerman - Rochester MN, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 7/00
G06F 17/30
US Classification:
707741, 707715, 707754
Abstract:
An operating system on a source computer system includes a filtered remote journal mechanism that generates a target map of a remote journal to specify where in the remote journal entries will be stored, then generates a vector array that represents the data of interest in the database journal based on specified selection criteria and the target map. The vector array and location information from the target map is then sent to a communication manager, which sends the data indicated in the vector array to the target computer system. On the target computer system, the communication manager reads the data sent from the source computer system and writes the data to the remote journal. The filtered remote journal mechanism may operate on an existing database journal, or may operate iteratively as journal entries are written on the source computer system.

US Patent:
20050283665, Dec 22, 2005
Filed:
Jun 17, 2004
Appl. No.:
10/870377
Inventors:
Margaret Levering - Rochester MN, US
Chad Olstad - Rochester MN, US
David Owen - Rochester MN, US
Larry Youngren - Rochester MN, US
Assignee:
INTERNATIONAL BUSINESS MACHINES CORPORATION - ARMONK NY
International Classification:
G06F017/30
US Classification:
714021000
Abstract:
A method, apparatus, system, and signal-bearing medium that in an embodiment determine, after a restore of a version of an object, where to begin applying changes from a change log to the object based on an identification in the saved version of the object. When a save command for an object is received, an identification of the change log entry associated with the save command is stored in the saved version of the object. Changes to the object then continue to be logged to the change log. After the saved version of the object is restored, the identification in the saved version of the object is used to find the change log entry at which to start applying changes from the change log to the object. In this way, the point in the change log at which to start applying changes to the object may be determined based on the saved version of the object. In an embodiment, this allows the object to continue to be accessed while the save operation is performed. Further, this prevents confusion as to which starting point in the change log to use when multiple save operations have been performed.
