Oracle Autonomous Database automates the lifecycle management of a database, everything from provisioning, scaling, backups and patching, but what it doesn’t do yet is fully tune your application.
You are still on the hook to make sure your app doesn’t have any concurrency bottlenecks or poorly written SQL that Auto Indexing can’t address.
So, what can you do to monitor your app while it’s running on an Autonomous Database?
The first place you can start is the Performance Hub tab on the cloud console. Here you’ll find both real-time and historical performance data in the form of Active Session History (ASH) information for the last seven days, and SQL Monitor reports for the high-load SQL. You can aggregate the ASH data several different ways including by wait class, database service, resource group or SQL ID. The same information is also available in Oracle Management Cloud (OMC), and SQL Developer Web.
But if you are trying to get a holistic view of how your app is behaving on a database, nothing beats an Automatic Workload Repository report or AWR report.
