RMAN Restore and Recovery
摘要
I said it in the previous chapter, and I will say it again, a backup is good only if you can use it to restore. Ideally, you will never need it, but a restore process needs to be documented, tested, and practiced. Practicing allows for errors to occur and for you to document strange things that can happen so that in a moment of panic and needing to complete the restore under pressure, you will be able to remain calm. It will also help verify that there are good backups available. One more benefit is that it allows you to be able to think through ways to get up and running very quickly.
