Maximizing Performance with Oracle 12 Memory Management（oracle12内存）

Oracle Database 12c is designed to provide the highest performance in terms of processing power, scalability, and data storage. Memory management is a critical factor in achieving optimal performance of Oracle 12. Before looking at ways to maximize performance with Oracle 12 memory management, let’s first discuss memory management in Oracle and its importance.

Oracle Database 12c utilizes a multi-memory architecture, allowing for the efficient utilization of system memory through the effective management of data and code components. Memory management for Oracle 12 ensures that all allocated memory is used efficiently and can be dynamically allocated to different requests. Memory management is responsible for allocating memory to the process that need access to the data. This keeps the system running smoothly and can save time, especially in situations where there are large numbers of requests for access to the same data.

Oracle 12 also provides an Automatic Memory Management (AMM) system that can be used to automate the process of memory allocation. The AMM system will monitor usage patterns to determine the optimal way to allocate memory to different requests and optimize system performance.

In order to maximize performance with Oracle 12 memory management, administrators can utilize memory integrity checks and memory buffer pool tuning. Memory Integrity Check allows administrators to check the integrity of the system’s memory and look for any possible memory leaks or other problems. This can help ensure that Oracle 12 is operating efficiently and that system performance is optimized.

Administrators can also use Memory Buffer Pool Tuning to automatically adjust the size of the memory buffer pool in order to optimize system performance. The Memory Buffer Pool Tuning feature monitors the process of data access and adjusts the buffer pool size based on usage patterns. This can help to ensure that data memory is allocated efficiently.

In addition to these features, administrators can utilize Automated Shared Memory Tuning (ASMT) to optimize shared memory usage. ASMT monitors usage patterns of applications accessing shared memory segments and makes real-time changes to the size of the segment based on the usage pattern. This feature works in conjunction with Memory Buffer Pool Tuning to ensure optimal memory performance.

To summarize, Oracle 12 offers several features that can be used to maximize performance with Oracle 12 memory management. Administrators can utilize Memory Integrity Check, Memory Buffer Pool Tuning and Automated Shared Memory Tuning to optimize system performance. By using these tools, administrators can ensure that Oracle 12 is running at peak performance.
