Oracle database administration (DBA) is the process of managing, organizing, handling, and upkeep the data stack for a business enterprise.
DBAs collaborate extensively with information systems managers and business analysts to choose or create databases that meet the company’s objectives and maintain the security and performance of those databases.
Today, a career in Oracle database administration has turned out to be lucrative only if one knows how to master it. In this article, you’ll learn all the DBA best practices that will help you master Oracle DBA in no time.
Get an Oracle DBA Certification
For any budding Oracle DBA, the Oracle Certified Professional (OCP) certification is an excellent way to begin their career.
Even though it’s not ideal, and getting certified won’t make you a master in Oracle DBA, you can start down the right road if you do it properly.
Learn More About Virtualization
When learning Oracle DBA, make sure you work with several operating systems. Using the Oracle VirtualBox is a good approach to appreciating new operating systems.
This will assist you in running as many virtual computer systems as you want with numerous operating systems. It will equip you with adequate skills and expertise to deal with more challenging virtualization tasks.
Expand Your Knowledge & Skill of Operating System
The next stage is to continue expanding your understanding of operating systems once you are at ease with the fundamentals of working as an Oracle DBA and virtualization.
This is particularly relevant if Windows is your main learning environment. You can anticipate working primarily on Linux and UNIX systems as an Oracle DBA. Therefore, you should feel at ease with those.
Learn Oracle on Linux
Once satisfied with VirtualBox and the Linux installation on VMs, you might think about performing a straightforward Oracle installation on a Linux VM.
Experts recommend starting out using Oracle’s simple file system and staying away from more complicated technologies like ASM until you feel more comfortable using them. Play with these things a bit. Attempt to fix it after you break it.
Create backups and recoveries. Make several installations. Update the OS and database, if possible. Be sure to perform typical DBA tasks. Don’t think that after one successful installation, you are done.
Master In Automatic Storage Manager
Once you feel comfortable with that fundamental information, you could look at installations using Automatic Storage Manager (ASM).
You will require some components of the Grid Infrastructure technology, which is a prerequisite for Real Application Cluster (RAC) installations if you intend to use ASM. The transition to RAC will be much simpler if you spend some time learning about ASM and Grid Infrastructure tools like Oracle restart.
RAC or Real Application Clusters
A virtual RAC installation is something you might think about when all the preliminary work has been completed, and you desire a tougher challenge. Operating systems and networking are just two topics that Oracle RAC requires some understanding of.
Conclusion
It will seem natural to move forward if you have taken your time learning all the qualifications. Work over the technology stack systematically. As you go, read the instructions and test things. Create a solid foundation to aid your advancement, have original ideas, and develop into a competent DBA.
