A method, apparatus, and article of manufacture for a computer-implemented repartitioning system. Data is repartitioned in a database stored on a data storage device connected to a computer. First, it is detected that a partitioning scheme for the data has been altered. Next, partitions that would be affected by the altered partitioning scheme are identified. Then, the identified partitions are reorganized based on the altered partitioning scheme.

Repartitioning data

A method, apparatus, and article of manufacture for a computer implemented recovery system for restoring a database in a computer. The database contains objects and is stored on a primary data storage device connected to the computer. Objects of different types in the database are copied from the primary data storage device to a secondary data storage device. Modifications to the objects are logged in a log file. A recovery indicator is received that indicates that recovery of the objects in the database is required. The objects are copied from the secondary data storage device to the database on the primary data storage device. Modifications in the log file are applied to the copied objects during one pass through the log file.
