Adjusting Oracle’s parameter settings can improve the performance and availability of the database system, here are some common adjustment recommendations:<\/p>\n

    \n
  1. Optimize SGA parameters: The System Global Area (SGA) is a memory area of the Oracle database that includes the shared pool, database buffer cache, and redo buffer cache. By adjusting the size of the SGA parameters, you can improve the performance of the database. Generally, the shared pool and database buffer cache should be set sufficiently large to reduce disk I\/O operations.<\/li>\n
  2. Adjusting PGA parameters: PGA (Program Global Area) refers to the memory area that is dedicated to each user process connected to the database. By adjusting the size of PGA parameters, the memory overhead can be reduced, thus enhancing the performance of the database.<\/li>\n
  3. Optimize database cache parameters: Adjusting the size of database cache parameters, such as db_cache_size, can reduce disk I\/O operations and enhance database performance.<\/li>\n
  4. Adjusting log parameters: By adjusting the size of log parameters (such as log_buffer), database write performance can be improved, reduce the frequency of log flushing, and enhance the availability of the database.<\/li>\n
  5. Adjusting connection parameters such as sessions and processes can enhance a database’s ability to handle concurrent processing, thereby improving the performance and availability of the database.<\/li>\n
  6. Performance monitoring: By monitoring performance parameters such as buffer cache hit ratio and redo log buffer hit ratio, database performance issues can be promptly identified and corrective actions can be taken in a timely manner.<\/li>\n
  7. Using AWR reports: By utilizing AWR (Automatic Workload Repository) reports, one can thoroughly analyze performance bottlenecks in the database and recommend corresponding optimization strategies.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
