How to Become Oracle DBA
Follow the steps listed below to become a successful Oracle DBA:

  1. Choosing OS Properly: If you’re fresh to Oracle, you want to minimize the number of unknowns you put into the mixture. Even so, you might want to begin the learning process mostly on the operating system that you are most acquainted with. If you’re the happiest on Windows, consider installing the Oracle Database from Windows. It is an excellent way to get it into the product without studying any new OS technologies.
    The vast majority of Oracle systems have been installed on a specific form of Linux or UNIX, so you’ll probably need to get acquainted with them at any stage, for now, but sticks to some of what you know.
  2. Checking Certification from Oracle: I believe the Oracle Certified people credential is a pretty decent initial step for any DBA you’re looking for. It isn’t easy, and gaining certification does not make you a good DBA, but you’ll take the first steps down the right path if you do it in the right direction. 
  3. Familiarize With Virtualization: You would be running on several operating systems as a DBA. A quick and easy way to go and get a feeling for new operating systems is to learn to experiment with Oracle VirtualBox. It will continue to run several virtual machines with various operating systems on your PC, allowing you the ability to become more acquainted with them in a secure environment. It is just going to be a stepping stone to do some more complex things later. There is a simple analogy of using VirtualBox to build a VM.
    I’d say you are playing with creating a few VMs, downloading Windows, and several Linux distros, like Oracle Linux models, Ubuntu, and maybe Fedora. It’s not necessary to get into that much detail for any of these Linux distributions at first. It’s all like cutting your teeth on VirtualBox. Doing several items can help you appreciate virtualization in particular and the product itself. You can also benefit from reading a simple guide to virtualization.
  4. Broadening Knowledge about Operating System: Regarding the previous move, once you feel familiar with the fundamentals of becoming an Oracle DBA and virtualization, you might undoubtedly begin extending your knowledge of operating systems. It is particularly true if your primary learning medium is Windows. Much of the job you do as an Oracle DBA would be on Linux and UNIX platforms, so you need to be familiar with them.
    The best way to do this is to utilize Oracle Linux, which would be free and supported. The better your Linux grounding, the simpler it would be to find more complicated projects, such as RAC installs, in the future.
  5. Working on Oracle on a Linux OS: Once you’re satisfied with VirtualBox and installing Linux on VMs, you might try to do a necessary Oracle installation on a Linux VM. 
    Play with this stuff. Rip it down and try to repair it. Do a backup to get back up. Do many installs, please. Try updates to the OS, servers, etc. Try to emulate standard DBA functions. Don’t just say that one exemplary implementation means you’re able to move forward.
  6. Automatic Manager of Storage: If you feel secure about the fundamentals, you might start looking at installations using the Automated Manager of Storage. Using ASM means that you will require some aspects of the Grid Infrastructure Technology, your step stone to the Actual Application Cluster facility. If you spend some time learning ASM and Grid Infrastructure technology such as Oracle’s rebuild, advancement to RAC would be much simpler.
  7. Clusters of Real Application: Once all the initial groundwork has been done, but you want a more significant task, you should suggest a virtual RAC installation. Here are few examples of this on this page.
    Oracle RAC needs some expertise in a variety of fields, like operating systems and networking. Without them, you’re making a ton of errors and find the process extremely angry. If you’ve taken your time to learn all the fundamentals, it’ll feel like a natural progression.

So this is all the information that a beginner should know about becoming an Oracle DBA. Now start preparing for the advanced topics and be the best Oracle DBA.
