Abstract:
A system for logging database transactions comprises a memory (comprising a direct access storage device) operable to store a database, a database log, and a plurality of log buffers associated with the database log. Each log buffer is operable to store at least one log record associated with a database transaction. The system further comprises a processor operable to log a first record of a first database transaction using the database log and write the database log to the storage device. The processor is further operable to log a second record of a second database transaction in a first of the plurality of log buffers substantially concurrently to the database log being written to the storage device.
