How are significant performance changes reported in Oracle Autonomous Database?

Significant performance changes in Oracle Autonomous Database are reported through AWR (Automatic Workload Repository) reports and the performance hub. AWR is a built-in performance monitoring and reporting tool that collects and retains performance data over time. It provides valuable insights into the database’s workload, system performance, and resource usage. The performance hub, on the other hand, offers a real-time graphical representation of performance metrics, making it easier for users to identify performance bottlenecks or changes.

Using AWR reports and the performance hub allows administrators and database users to conduct in-depth analyses of performance trends, identify areas that require optimization, and take proactive measures to ensure optimal database performance. This capability is essential for maintaining the efficiency of an autonomous database, where automated tuning may be performed based on the insights gathered.

The other options are less aligned with how significant performance changes are officially communicated within Oracle Autonomous Database. Regular maintenance logs focus more on system updates rather than detailed performance metrics. User feedback mechanisms typically collect subjective insights rather than quantitative performance analysis. System alerts might notify users of issues, but they do not provide the comprehensive data that AWR reports and performance hub do.
