Adjusting extension size of a database table using a volatile database table attribute
First Claim
1. A computer program product for managing a computerized database, the computer program product comprising a plurality of computer-executable instructions recorded in a non-transitory computer-readable media, wherein said instructions, when executed by at least one computer system, cause the at least one computer system to perform:
- storing at least one respective database table volatility attribute for each of at least one database table of said computerized database, each database table volatility attribute expressing volatility of at least a portion of a respective database table of said computerized database, said volatility of at least a portion of a respective database table being a property of the respective database table that is a function of changes to data recorded in said at least a portion of the respective database table with respect to time;
determining an extension file size of at least a portion of a first database table of said at least one database table of said computerized database using the at least one database table volatility attribute corresponding to the first database table;
responsive to a need to increase the file size allocation of the at least a portion of the first database table, increasing the file size allocation of the at least a portion of the first database table by the amount of the extension file size determined by said determining an extension file size of at least a portion of a first database table.

Abstract
A respective volatility attribute associated with each of one or more tables of a computerized database is used to adjust an extension file size value associated with a database table file space. Various optional additional uses of a volatility attribute to manage a database are disclosed. Preferably, database parameters are automatically monitored over time and database table volatility state is automatically determined and periodically adjusted.

9. A computer system supporting a database, comprising:
-
a memory; at least one processor executing instructions storable in said memory; at least one database table of said database storable in said memory; and a database manager embodied as instructions storable in said memory and executable on said at least one processor, said database manager managing said database and providing access to data in said database table; said database manager including a file extension function which determines an extension file size of at least a portion of a first database table of said at least one table of said database using at least one database table volatility attribute corresponding to the first database table, the database table volatility attribute expressing a property of the first database table that is a function of changes to data recorded in said at least a portion of the first database table with respect to time, said file extension function further, responsive to a need to increase the file size allocation of the at least a portion of the first database table, increasing the file size allocation of the at least a portion of the first database table by the amount of the extension file size it determines. - View Dependent Claims (10)

11. A computer program product for managing a computerized database, the computer program product comprising a plurality of computer-executable instructions recorded in a non-transitory computer-readable media, wherein said instructions, when executed by at least one computer system, cause the at least one computer system to perform:
-
determining a volatility state of at least a portion of a database table of a computerized database, said volatility state being a property of the database table that is a function of changes to data recorded in the at least a portion of the database table with respect to time; recording a database table volatility attribute expressing said volatility state; and determining an extension file size of the at least a portion of the database table of the computerized database using the database table volatility attribute, the extension file size being an increment by which the at least a portion of the database table is increased responsive to a need for additional file size allocation of the at least a portion of the database table. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
