Where to start learning to become a successful Oracle DBA I am IT Graduate with good knowledge on SQL and C. I have done most of the SQL programming on Microsoft SQL Server in my academics. But i want to become Oracle DBA. Could you please suggest me a structural way to to start learning.  And also please suggest me what background work is needed before digging into it.
Thanks
Start with the Oracle Concepts Guide (pdf). It will give you a good overview of everything related to Oracle databases and will give you a framework in which to place everything else you learn about Oracle.  While you will by no means be a DBA after reading the guide, this is where you should start.
