Oracle Performance Monitoring Guide

Monitoring and optimizing Oracle performance metrics is essential for ensuring the normal operation of the database system. Here are some commonly used methods:

1. Monitoring tools: Oracle offers a variety of monitoring tools such as Enterprise Manager, SQL Performance Analyzer, and SQL Tuning Advisor, which can be used to view database performance metrics and make optimizations.
2. Performance indicators: Commonly used performance indicators include CPU utilization, memory utilization, disk I/O, network I/O, etc., which can be viewed through views and commands provided by Oracle.
3. SQL optimization: For SQL statements with poor performance, optimization can be done using tools like SQL Tuning Advisor to improve query efficiency.
4. Index optimization: Indexing is an important method for improving query efficiency, and it involves analyzing query plans to optimize tables with indexes.
5. Regular maintenance: Conduct regular database statistics collection, space cleaning, log cleaning, and other maintenance work to ensure the healthy state of the database.
6. Monitor alert: configure alert rules to promptly send out alerts when database performance metrics are abnormal, and promptly address any issues.

By using the above methods, it is possible to promptly monitor database performance metrics, identify issues, and optimize them to ensure the normal operation of the database system.
