Hi Vinod,

I am working for past 4 years as sql dba. I had seen many of my team members(oracle dba's) (even who are from other states) studying material from wilshire. I had also undergone training for oracle dba in wilshire (madhu sir classes). Its the best institute in south india for oracle dba training. It is affordable and quality of training is very good.Recently wilshire had kept its course material online(http://www.wilshiresoft.com/). I recommend you to go for wilshire(8k to 10k) or sql star (if you can afford around 50 to 60k).
