what should i prefer for oca 11g,10g or 9i technology??
my teacher says that i should go for 9i as it is very rich in basics and works only in command lineIf that is what your teacher said your teacher worries me ....
.... [a]nd industries relies on cmdIn general less and less so. And I would estimate the current percentages of databases in existance at different versions for 12c/11g/10g/9i/other is something currently like 1/52/32/12/3 ( Thats only an estimate .... by this time next year (or soon thereafter) it will be something like (10/50/30/8/2)). [ 12c production will still be rare; 12c development more common].
so tell me what would be better for me to opt??Dump your teacher ?

yes i am talking about 9i DBA OCA
i can not dump my teacher as i had already paid up the fees :(
can you suggest me some other better option??No sure why the compulsion of next week. But everyone has their reasons. ( I for instance may choose to take 1z0-146 next week before I am totally satisfied with my preparation for it .... but that is because if I dont take it then I may have insufficent time to concentrate on it for a while and I may edge off peak. I will evaluate the cost/risk/benefit for that next week).
i had to take sql exam in the next week so what should i prefer??
which paper code 9i, or 11g??
i had to take sql exam in the next week so what should i prefer?? which paper code 9i, or 11g??A couple of weeks ago, a poster was indicating that he wanted his Oracle certifications to be valuable to his career for the next 35 years. My post in that thread noted that 35 years ago was 1978, when mainframes ruled the world. If you plan on a career in Information Technology, you need to plan on a career where you are constantly retraining yourself to take advantage of what is important right now, not what was important five years ago. There are certainly companies still using Oracle 9i. Oracle databases are used by companies for running Enterprise applications. The data is important. Downtime is expensive. Change is scary. All of these things make many companies very conservative when it comes to upgrading to new releases of the software. That said, part of the reason they use Oracle is because of the world-class support that Oracle corporation provides to their databases. That support doesn't last forever. Oracle does desupport versions over time. No more bugfixes, no more guarantees that problems will be made right. Companies will move on to newer releases.
