Caveats
We have taken the Pareto’s Law approach in writing this book, in that we have tried to cover topics that you are most likely to encounter while using RMAN. This material does not cover every type of environment, nor does it cover all of the backup and recovery scenarios that you will encounter as an Oracle DBA.
While some of the more common backup and recovery scenarios are covered in this book, it is still critical that you are comfortable with your RMAN implementation and can recover your database no matter what type of failure occurs. We can’t stress enough the importance of regular testing in preparation for recovering from unplanned disasters.
A sound implementation and regular testing will give you the confidence to handle the impending 2 A.M. call: “Hey, I’m getting this strange ORA-01116 error, unable to open file, what do I do?”
