How to become an Oracle expert?

Well, as a DBA, you have made unremitting efforts for a long time. You feel that you are ready to take another step. What do I need to become a senior DBA? The following sections help you proceed.

Step #1: Read all documents-Oracle documents are generally not easy to read. Countless times, you read the document just to find out the whole thing. If documents are the best, then oracle books standing on your shelves will not be available. However, the document does contain information that cannot be found anywhere else. For example, you cannot find detailed descriptions of every special init. ora parameter or V $ view. Some may be involved in books, but Oracle documents include all of them. I met a very powerful senior DBA who did not read the Oracle document from the beginning to the end. This is not accidental. Oracle documents must be read. Maybe you have read the Oracle concept guidance 12 times so far. But when Oracle 10i is released, read it again. Any new concepts related to 10i will be documented in this document. If you really want to go further, read those documents. Do not escape it.

Step #2: become an expert-Oracle database is a very complicated thing. To be more advanced, you must be proficient in many components of the product. Start with backup and recovery. Become a backup and recovery expert. Deliberately destroys the database and then looks at how to recover it. Try to destroy the database in any way possible and check whether the database can be recovered. You will thoroughly understand the concept of backup and recovery. After you become an expert in backup and recovery, you can become an expert in other fields. You will have endless questions to grasp. This remains the case throughout your career. But remember, no matter how professional you are, some people will know more about you in some areas. Do not bring personal emotions. Just learn as much knowledge as possible from that person.

Route #3: actively participate in newsgroups, forums, and user groups-I mentioned why different newsgroups and forums are a good place to learn new knowledge. Now it's your turn to take the next step and answer any questions you can answer. You will be surprised to learn so much in this process!

Route #4: Write a White Paper and show them-this is similar to the method mentioned above. First, sharing your knowledge is very important. If your career has reached this step, in a sense, it is inseparable from others' contributions. Therefore, it is time for you to contribute to others. Second, when you try to share your information, something amazing will happen. When you use clear, concise language to express problems so that others can use them, the information goes through a staggering process in your mind. This process reinforces your knowledge, which cannot be done in other ways. Sharing that information, seminars, news groups, and forums in the White Paper is a very good way for you to learn and make your abilities more advanced. Follow this path and you should do two things. First, realize that you will make mistakes. Others will be happy to point out the mistakes, sometimes not very good in a sense. Do not attempt to hide your mistakes. Recognize and learn from them. Second, learn to say that you do not know the answer, rather than trying to pass through the deception. Sooner or later, people will know that you are attempting to blind them. Simply tell them that you are not sure about the answer, but you will come back and tell them the answer. If you keep these two things in mind, you will not be against your honesty and you will grow into an IT professional.

Step #5: Become an Oracle expert-Senior DBAs are generally considered to be the people who solve complicated Oracle problems. You will use all your technologies to solve many problems that have been accumulated in your career. Everything I mentioned above will be used to solve the problem. documents, books, newsgroups, test cases, and other DBAs will help you solve the problem.

Step #6: become an expert in performance tuning-Senior DBAs are generally regarded as adjusting databases and applicationsProgramPerformance. If you are a senior DBA but you cannot analyze performance bottlenecks, your company will look for these services elsewhere.

Step #7: become an expert in the bearer capacity plan-Senior DBAs are generally considered to be the people who plan the database capacity based on the data growth and transaction growth. Senior DBAs need to identify system bottlenecks before affecting application performance. For example, DBA should know that more disk space is preset before the database uses up available disk space. If you do not pay close attention to the bearer capacity plan, the production database will be down.

Step #8: pay close attention to new technologies-Senior DBAs should have good suggestions on the future of IT-related database technologies. What technologies are available to help databases? For example, learn the advantages and disadvantages of the storage domain network and how to apply them to the database system. What technologies will be available in the near future and help us? For example, write this articleArticleLinux operating systems are becoming increasingly popular. What does Lunix bring to your database operating system platform? Can it work for your company?
