You would need to know more about the situation to have any meaningful response.

hi

well in my interview i had given answer that ... 75-80% side tunning is doen by user who develop application by doing normalization of table etc. and the rest 20% is doen on Database side ... so if someone tell me to tune database then i will do SQL tuning first because on database side tunning if Sql are tunned then most of problem of database is solved...please suggest me if you think what i had answered was wrong

thank your very much smartin and frank

regards
sunil

Sunil,

You should definitely read this, Chapter 1 from Millsap and Holt's Optimizing Oracle Performance.

Here is the relevant pull quote, from page 12:

Quote:

Work first to reduce the biggest response time component of a business' most important user action.
