DBA expert circle in the 2.0 age-Oracle DBA note

After reading the manuscript "Oracle DBA manual" sent by eygle, I felt that the writing idea of this book was quite new. With the improvement of Database Technology automation, DBA's work value has begun to expand to a greater level. Therefore, sharing the experiences of some Pathfinder has become particularly valuable. Exposing its thinking process is a major feature of the technology circle in the web era. In some previous times, some engineers used technology only as a profitable craft. Many operating skills were kept confidential, and they were always afraid that they would "teach the apprentice and starve the master to death ". The arrangement of this book is a denial of this backward thinking. It has three main characteristics:

Editing and Selection: In the search age, wizard is needed.
In the age of ubiquitous search, the difficulty of getting started with a certain kind of knowledge is not the acquisition of knowledge, but the filtering of knowledge. At this time, the understanding of people who come over is often the best reference. If the pleasure of scientists comes from the discovery of the creator, the pleasure of top engineers comes from understanding the wisdom of others. In the final analysis, the entire software industry is based on the design of the mathematical foundation of human thinking. From the root point of view, software technology itself is the crystallization of human intelligence. On the other hand, experience is indispensable because of the complexity of the database technology application environment. For an entry-level dBA, two things are crucial to the advanced stage: understanding what the designer thinks, and understanding the complexity of the user's environment. Both require experience accumulation and diligence.

Collective creation: the self-organization of small groups Brings multi-dimensional inspiration
In terms of technology, each person has different root machines. Therefore, different ways of inspiration vary. Several DBAs master their daily experiences and screen them into a set. On the one hand, they are based on the principle of specialization in the industry, and on the other hand, they bring about an increase in dimensions to the reader's inspiration. Maybe a reader just liked Yang Tingting's understanding and text expression, so he could spend more time watching his 1500-plus blogs. Some may appreciate the technical capabilities and ways of human use of eygle. Therefore, they can learn from each other and avoid detours. Masters get started, practice in the individual, martial arts novels in the apprentice to learn the legend of art, now can be copied on a wider range of the network, but readers now have more choices. The collective creation of this book brings more dimensions and helps readers to increase their understanding.

Share your thoughts: What do I think?
In ancient times, intellectuals in the study did not let others into the study. What they feared was that they had read their minds. The spirit of Web 2.0 is the opposite. If the development of technical knowledge far exceeds the individual's learning ability and forms a culture of sharing, it is extremely necessary to avoid detours. The key is to expose the thinking process and tell others their thoughts on specific issues. These ideas will gradually converge into a way of thinking, which is longer-term than a specific version of operation skills. The notes of the authors in the first part of this book reflect such a spirit.

The release of this book coincides with the release of Oracle 11gr2. The design of the new version is oriented to the data center and adds more technical features. DBAs are no longer limited to databases, instead, we should focus on building a larger data center. Therefore, I hope that this book will be of great benefit to DBAs in their daily work and have the opportunity to look up for a longer term.
