In this talk we examine the "before-image file", what it's for, how it works, and how you can configure it properly. You might get answers to questions that have been troubling people for over 25 * 10-2 centuries:
Why doesn't the before-image file have before-images ?
Why aren't the data on disk ever current when the database is being used?
What are checkpoints ?
Why do we have them ?
When your system crashes (and they all do eventually) how can the RDBMS recreate all the data that were lost in the crash and restore your database to a consistent state?
Hello Gus,Thank you, this is really a good presentation.Regards,Kaan
