Hi, Do you want to give Oracle certification in developer side or DBA(Database Administrator) side. For DBA you will first need to complete Oracle Certified Database Associate (OCA). You can give OCA for the current oracle version 10g. For OCA 10g you will have to clear Oracle Database Administrator 1 (1Z0-042) exam.
