Analyze Database Performance

With the Database Performance dashboard you can gain insights into your fleet's database performance with a comprehensive fleet-level view. Track the overall workload, identify databases with the highest workload, and pinpoint actionable areas for optimization. View granular information into specific databases top activities and ADDM recommendations.

To access the Database performance dashboard, open the navigation menu, click Observability & Management, and then click Ops Insights. In the left pane, click Database Insights, and then click DB Performance.

Use the Applied filters bar at the top of the page to define the global scope and filters for the Database performance dashboard. Select a compartment, optionally select Subcompartments to include child compartments, select a database, optionally select a tag value, and set the time range.

The Database performance dashboard allows you to at a glance view your database Inventory, detailing in a pie chart the different types of database versions your environment has and the percentage breakdown of these. Below this graph the following insights are displayed:
  • CPU insight: Databases shown having excess database time, and/or scheduler wait time exceeding 1% of total database time. This insight is indicative of databases with saturated CPU's or the Resource manager CPU-limiting some consumer groups.
  • Degrading SQL: Databases having SQL with a degraded response time.
  • High wait time: Databases where non IO (Input-Output) wait time has exceeded 50% of the database CPU time.
  • ADDM recommendations: ADDM spotlight recommendations for the selected databases that will result in high performance improvement benefits.

The main graph area shows two tabs Top activity and Load map. The Top Activity chart details a breakdown of total fleet database time over the selected time period. It will show the top 7 busiest databases in units of average active sessions. The Load map displays a treemap of the total database time over the selected time period.

The table at the bottom of the dashboard shows the Top databases by activity, allowing you to see the list of top 10 databases by active sessions.
