Oracle learning experience

I often ask my friends how to become a master when learning oracle. I would like to give a few simple points based on my personal experience:

1. lay a good foundation from a simple perspective

Learning Oracle cannot rush to success, and hopes to become a hero one day. There is a learning process, which should be easy to understand and lay a good foundation in the learning process. In this way, you will be able to bypass the class in the future.

In my personal experience, it is recommended that you first learn the Oracle architecture and other content trained by Oca, then learn the RMAN and Data Pump content of OCP, and finally learn the RAC, dataguard, and stream of OCM. If you do not know how Oracle starts and closes, it does not make much sense to study RAC and dataguard.
2. Multi-practice and multi-Data Query

Oracle is mainly based on practice, which constantly improves our hands-on operations and the ability to solve practical problems. Therefore, in the course of learning, we need to build an oracle learning environment. We need to practice more commands in documents and tutorials to ensure they are correct and feasible. There is a lot of information on the Internet, mostly summarized by the author, which cannot be applied in any environment. Practice is the only criterion for truth verification.

3. More communication and more questions

Oracle is profound and profound, and it does not rely on the power of one person to exhaust it. It is necessary to make full use of the internet tool. In Oracle forums and QQ groups, you can communicate with other people. If you have any problems, you can solve them together. Three stinks have competed with Zhuge Liang. Oracle Forum I often go to it O & M Chinese network http://www.zhuanyou8.com, QQ Group has a lot, a search engine, I also set up a few Oracle QQ Group 60618621 and 23145225, you are welcome to discuss Oracle technology with me. I believe that only by learning from each other and learning from each other can we improve quickly.
As long as you focus and keep working hard, I believe everyone can become a master. Come on!
