Abstract
Official abstract text for this publication.
A method for of accelerating database log hardening using specific per block data protection and damage control is provided. A per write specification is implemented to determine when database log data is mirrored synchronously or asynchronously. Synchronous mirroring is performed upon reaching a predetermined threshold, based on one or more parameters such as transaction value, both individual and cumulative, and the quantity of data written since the last synchronous mirroring. As data is added to the database log, it is written specifying asynchronous mirroring to the primary log file. Once a threshold is met, a write specifying synchronous mirroring is performed to both the primary and secondary log files, thereby hardening the log file in both primary and secondary storage subsystem.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of mirroring log data from a primary storage subsystem to a secondary storage subsystem, the method comprising: initiating a transaction in response to receiving a write instruction; determining a value of the transaction; adding the value of the transaction to a cumulative value of transaction values since a most recent synchronous mirroring; performing an asynchronous mirroring of the log data when the cumulative value does not exceed a dama…
