US Patent:

8392423, Mar 5, 2013
Filed:

Jul 2, 2010
Appl. No.:

12/829893
Inventors:

Jon C. Belisle - Tucson AZ, US
David C. Reed - Tucson AZ, US
Max D. Smith - Tucson AZ, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06F 17/30
G06F 7/00
US Classification:

707741, 707668
Abstract:

Various embodiments for preserving data set information in a computing storage environment are provided. In one such embodiment, at least one of a selected portion of an index record of the dataset is stored as a record in a subindex data set. The at least one component of the subindex data set is recoverable into the index record in an event of an error detected within the index record.

US Patent:

8589652, Nov 19, 2013
Filed:

Sep 13, 2012
Appl. No.:

13/614710
Inventors:

Jon Christopher Belisle - Tucson AZ, US
David Charles Reed - Tucson AZ, US
Max Douglas Smith - Tucson AZ, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06F 3/06
US Classification:

711165, 707828, 711E12002
Abstract:

A directory and members are allocated to store a data set, wherein the directory stores pointers to the members to allow data stored in the members to be accessed. The directory is expanded to accommodate an expansion of the data set, causing the directory to be stored in non-contiguous pages and becoming fragmented. A computational device determines that a threshold that measures a level of fragmentation of the directory relative to an amount of storage allocated for the data set has been exceeded. The computational device reorganizes the fragmented directory, into a reorganized directory that is stored in contiguous pages at the end of the data set, in response to determining that the threshold has been exceeded.
