I have been getting so many inquiries from the various candidate who are having keen interest to be Oracle DBA. I am providing some information regarding this.
DBA (Database Administrator) is a person who is an expert with exceptional skills required in the fields of database management. These professionals are the worker bees that make sure that the system runs smooth and without any glitches. It is their primary duty to troubleshoot any problem. Especially developed certifications, training and hands-on experience are offered by database product manufacturers to train professionals to handle their products and solutions. DBA is a busy person in a corporate environment, even income corporate structures there are a number of DBAs at a single site. This all depends upon the complexity of the whole system.
DBA professional is a person who is equipped with the latest and up-to-date knowledge of the database system of his own choice. Advance knowledge is then combined with periodical training held by the manufacturer i.e. Oracle, and the final element, experience. Experience is considered to be the most important element, it is the stage when you get personal experience to troubleshoot the database system. A person who lacks any of these three elements would fail in his attempt to be called DBA.
Before purchasing the necessary course materials one should choose the correct database platform to begin. Latest platforms developed and launched by Oracle include the reliable 11g and 10g products. So one needs to choose the course for induction, he has ample choice such as Oracle DBA 11g or Oracle DBA 10g along with necessary Oracle DBA training. Once a person has made up his mind, the next step is to get admission in an authorized training and testing center. This is necessary and is mandatory for beginners. Experienced professionals would be able to benefit from their previous experience.
The route to Certified Oracle DBA is divided into three brief steps. These steps are interconnected and one must complete all three steps to complete his certification. The very first step is Oracle Certified Associate, this is the initial step and is composed of three exams. You must pass at least two to make it to the second step. Oracle Certified Professional is the second step professional, it is necessary to acquire training at this level to qualify for the next final level. Along with training you also need to pass the examination. Once cleared now you move to the final level the Oracle Certified Master, you need to get advanced training and have to pass at least two exams to become the Oracle DBA.
This is a long road but it is very much necessary so that you can actually perform your job. Maintaining and troubleshooting Oracle database systems can only be performed by a certified professional. A huge commercial and corporate firms have giant interlinked database systems that interact around the world. Only a certified person will be able to point out the problem and fix it. Confidence is also boosted with the training that you get in the three qualification levels. You will also get a chance to upgrade your knowledge in future too.
