Oracle DBA Advice: How To Become A Master
Become Certified As An Oracle DBA
The Oracle Certified Professional certification (OCP), which will put aspiring Oracle DBAs on the right career path, has substantial benefits for beginning DBAs. Although obtaining an Oracle DBA certification won't turn you into an expert, you can start along the path to becoming an expert in this field by following these steps.
Virtualization
When studying, be sure to practice Oracle DBA on a variety of operating systems. Oracle VirtualBox is a useful tool for getting acquainted with new operating systems. You will be prepared to take on more difficult virtualization duties if you can run many virtual PCs at once.
Boost Your Understanding Of Operating Systems
After you have mastered virtualization and Oracle DBA, it's time to expand your operating system expertise.
Your daily responsibilities as an Oracle DBA will involve working mostly with Linux- and UNIX-based systems. Thus, familiarity is crucial.
Learn Oracle On Linux
After you're comfortable with VirtualBox and installing Linux in virtual machines (VMs), try installing Oracle on a basic machine. When you feel more comfortable, experts suggest starting with familiarizing yourself with Oracle's basic files system and working your way up to more advanced technologies like ASM. Try out several features; if something goes wrong, repair it right away.
Backups and recoveries are essential; to ensure these are done correctly, run numerous software installations before updating the operating system and database as needed, carry out standard DBA tasks, and don't assume that just because an installation goes smoothly, your work is done.
