I started this question because a friend on MSN asked me today,What is DSI?.
This is the first question.
DSI isData Server InternalsIt is an internal teaching material used by Oracle to train Oracle aftersales engineers.
Such documents are usually printed:Oracle confidential: for internal use only.
Therefore, the dissemination of such documents is generally prohibited by Oracle, but for some special reasons, these documents are also widely circulated.
You can find some related information from Google, but the requests for any DSI textbooks are quite sensitive.
A lot of people are eager for confidentiality, which may be inappropriate.
This document is not suitable for beginners, because it is difficult to start from here, and the readers need to have a profound technical foundation. Beginners should learn from the basics. After you lay the foundation, you can also read these documents one day.
