Hi Christopher,
So, are you going to tell the list what the answers are so that those
that don't know can benefit.

1. What is the difference between a lock and a latch?
2. Explain what spinning is and why is it necessary?
3. What is the PL/SQL catch all exception called?
4. Where would you "read" about a deadlock that occurred?
5. How would you verify your data files you just backed up are not corrupt?
6. Explain what two significant things that occur when you do a BEGIN
BACKUP on a tablespace.
7. Explain the use of DECODE function.
8. What is a correlated sub query?
9. Explain the "snapshot too old" error, and when does it commonly occur.
10. What three powerful Oracle tuning tools require timed_statistics?
These are off the top of my head, I had a nice drawn up list I spent more
time on, but it is at home I think.

If you were to choose 10 questions to evaluate the competency of a DBA what
would they be given that the result would be their competence would be rated
as of the following:
- TERRIBLE (I would not let them within 100 miles of a database)
- FAIR (I'd show them some basic admin, but do it myself, they've a
lot to learn yet)
- GOOD (I'd let them do some basic admin stuff by themselves but
monitor their performance regularly)
- VERY GOOD (I'd let them handle practically all admin type work and mentor
them as required)
- EXCELLENT (Hell, they could teach me a trick or too!)
