hi
you can use bbed, its an undocumentated executable though
Funny topic, eh? I am practicing backup and recovery procedures and finding that recovery is quite easy since I never have corrupted blocks to worry about. So, how do I practice for a "worse case" scenarios? Are there white papers out there that go over this kind of stuff? I found several "Best Practices" in metalink (look Mladen, not plural), but that is not exactly what I am looking for as they tell you how to fix the problem, not make the problem. I have tried overwriting the binary files, but being simpled-minded I was using vi. I thought about using the unix dd utility - unfortuantely I do not have enough experience to be surgical (easy to mess up the first few blocks, but what about the middle?). Can I use the same method to isolate corruption to various parts of the database (ie, database files, redo logs or rman backups)?
I have a gut feeling that someone has already documented this, so if this is the case, please point me there. Thanks,
PS - I have been practicing on 9iR2. Yet anything above 9iR1 would be fine.
