I am new to Oracle. What you guys will suggest for me to do certifications at first. I am aware of Oracle basics but not certified.
You are in the WRONG forum. This sub-space of the forum is for people who have achieved Oracle Certified Master certification.
MODERATORS: please move this thread to --> Certification Community
But to answer your very VAGUE question, it's like you asking, I want to be a "doctor", and I say "What KIND of doctor?"
First you need to decide what area do you want to get certified in, then focus on the basics. Are you an Oracle DBA (DataBase Admininstrator)? Or an Oracle Developer?
