Abstract

See full text

A database receives pages that are piped from backup media with each of the pages having a corresponding savepoint version. At least a portion of the pages are then flagged as being from recovery. The savepoint versions for the pages are maintained if they have a flag. A single checksum is then calculated for each page to confirm integrity. Each page is then loaded into memory of the database after it is confirming the corresponding calculated single checksum. Related apparatus, systems, techniques and articles are also described.
