Re: [OffTopic] Curiosity about vision of the future for dba oracle ...

Hey Mladen,

Just out of curiosity - How can adding more memory or CPU help you with SQLs that ....

1. ... spent most time on logical I/O due to inefficient exec plans (single thread)
2. ... spent most time on parsing (single thread)
3. ... spent most time on sorting due to inefficient exec plans (single thread)
4. ... spent most time on hashing/looping due to inefficient exec plans (single thread)
5. ... etc.

I thought that we already overcame the mindset of solving a software/SQL problem with hardware ;-)
