Abstract: By ensuring that sufficient information from the buffers is maintained so that all changes of uncommitted transactions can be recreated, the storage of the undo buffers into undo logs can be minimized. Further efficiencies may be maintained by keeping a count of actions in a transaction as the actions are undone.

Abstract: A data processing system maintains logs for system and media recovery. The logs contain state identifiers each uniquely identifying the state of a corresponding section of a storage medium, such as a disk. The state identifiers are assigned after changes have been made such that they can be determined from the information in the logs. One implementation involves assigning state identifiers in a known sequence, such as in a monotonically increasing sequence of integers beginning with zero.
