Abstract
Abstract A method, apparatus, and article of manufacture for a computer implemented reorganization system. A table space is reorganized in a database stored on a data storage device connected to a computer. When inserting or updating a LOB into a portion of the table space, a space map is marked to indicate whether the LOB was well inserted. When reorganizing the table space, when the space map indicates that a LOB was well inserted, reorganization of the portion of the table space in which the LOB was well inserted is avoided.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
97 words
A method of reorganizing a table space stored on a data storage device connected to a computer, the method comprising: when inserting or updating data into a portion of the table space, setting a flag in a space map which is associated with the data to indicate whether the data was well inserted, wherein the space map is stored in the table space with the data; and when reorganizing the table space, when the flag indicates that data was well inserted, avoiding reorganization of the portion of the table space in which the data was well inserted.
Claim 2
Independent Claim
97 words
A method of reorganizing a table space stored on a data storage device connected to a computer, the method comprising: when inserting or updating data into a portion of the table space, setting a flag in a space map which is associated with the data to indicate whether the data was well inserted, wherein the space map is stored in the table space with the data; and when reorganizing the table space, when the flag indicates that data was well inserted, avoiding reorganization of the portion of the table space in which the data was well inserted.
Claim 3
Dependent Claim
36 words
The method of claim 1 , wherein the method further comprises, when reorganizing the table space, when the flag indicates that the data was not well inserted, processing the data so that it is well inserted.
Claim 4
Dependent Claim
23 words
The method of claim 1 , wherein the method further comprises, as data is being inserted, tracking how the data is being inserted.
Claim 5
Dependent Claim
29 words
The method of claim 3 , wherein the method further comprises, after inserting the data, using information obtained from the tracking to determine whether the data was well inserted.
Claim 6
Dependent Claim
24 words
The method of claim 3 , wherein the method further comprises, as data is being updated, tracking of how the data is being updated.
Claim 7
Dependent Claim
29 words
The method of claim 5 , wherein the method further comprises, after updating the data, using information obtained from the tracking to determine whether the data was well inserted.
Claim 8
Independent Claim
113 words
An apparatus for reorganizing a table space, comprising: a computer having a data storage device connected thereto, wherein the data storage device stores the table space; one or more computer programs, performed by the computer, for, when inserting or updating data into a portion of the table space, setting a flag in a space map which is associated with the data to indicate whether the data was well inserted, wherein the space map is stored in the table space with the data, and, when reorganizing the table space, when the flag indicates that data was well inserted, avoiding reorganization of the portion of the table space in which the data was well inserted.
Claim 9
Independent Claim
113 words
An apparatus for reorganizing a table space, comprising: a computer having a data storage device connected thereto, wherein the data storage device stores the table space; one or more computer programs, performed by the computer, for, when inserting or updating data into a portion of the table space, setting a flag in a space map which is associated with the data to indicate whether the data was well inserted, wherein the space map is stored in the table space with the data, and, when reorganizing the table space, when the flag indicates that data was well inserted, avoiding reorganization of the portion of the table space in which the data was well inserted.
Claim 10
Dependent Claim
36 words
The apparatus of claim 7 , further comprising the means for, when reorganizing the table space, when the flag indicates that the data was not well inserted, processing the data so that it is well inserted.
Claim 11
Dependent Claim
23 words
The apparatus of claim 7 , further comprising the means for, as data is being inserted, tracking how the data is being inserted.
Claim 12
Dependent Claim
31 words
The apparatus of claim 9 , further comprising the means for, after inserting the data, using information obtained from the means for tracking to determine whether the data was well inserted.
