Oracle 12：研究内存结构的新思路

Oracle 12 introduces a new approach to researching the memory structure of the Oracle Server. This approach focuses on the use of the Oracle Memory Access Method (MAM), which allows for a more efficient and effective analysis of the memory structures of the Oracle Server.

The MAM is a plugin for the Oracle Debug Interface (ODI), and it is designed to enhance the functionality of the ODI by providing a comprehensive view of the Oracle memory structures. The MAM allows developers and DBAs to easily monitor and analyze the internal memory structures of the Oracle Server, such as the shared pool, buffer cache, and PGA.

One of the mn benefits of using the MAM is that it allows developers to quickly determine which memory structures are consuming the most memory. This can be particularly useful for large applications that require a lot of memory, as it allows developers to optimize their application code and reduce memory overhead.

Another key feature of the MAM is the ability to capture real-time memory usage statistics for Oracle processes. This allows developers to monitor the memory usage of their processes over time, and to quickly spot any memory leaks or performance issues.

In addition to the MAM, Oracle 12 also introduces several other improvements to memory management. One of the most significant improvements is in the area of automatic memory management (AMM). AMM is a feature that allows Oracle to automatically manage the memory of the Oracle Server, including the shared pool, buffer cache, and PGA.

In previous versions of Oracle, DBAs had to manually manage the memory structures of the Oracle Server, which was a time-consuming and error-prone process. With AMM, Oracle can now automatically manage the memory structures of the Oracle Server, freeing up valuable time for DBAs to focus on other critical tasks.

In conclusion, the introduction of the MAM and improvements to memory management in Oracle 12 represent a significant step forward in the area of Oracle memory management. By providing developers and DBAs with powerful tools for analyzing and optimizing memory usage, Oracle 12 is empowering organizations to build more efficient and effective applications and systems.
