Hi Regis, Thanks Regis..! Sorry, I think I missed your mail..! Thanks for all/any others whom I've missed in my list.! It was not intentional..! I subscribed to askdba after a very long time..earlier I was there in Lazydba..so many are known(thru email) to me ..and from others problems..I learnt more..and even for few questions..I used to respond..Pls show me the right direction if I was wrong in any of my emails..! Regis I like your way of approaching the problems..and in fact in this group I've learnt a lot..as am new to this DBA field. I cant name..but there are many persons..who give really good input for me. I've few questions..these are generic..which I faced during my interviews..!  What's the difference between normal DB(Client Server) and VLDB, which all we need to take care as part of DBA responsibility..? Similarly for Client server DB vs Datawarehousing DB.  If a user has just logged in and logged out without doing any transaction, can we come to know from any of the data dictionary views?, I know that using v$session I can see the currently logged on users. Am looking for DBA Interview questions..unable to find a good one..if you know any such..pls forward to me..!
