How AWR Snapshot Nodes Work

This node represents a single AWR snapshot in the database. An AWR Snapshot is a collection of database statistics and performance metrics gathered at a single point in time. Two snapshots are required to analyze database performance over their time period. This performance analysis is done by creating an ADDM Task.

When you run Oracle Performance Analyzer, it automatically creates begin and end snapshots. The database may also create AWR snapshots automatically at regular intervals, depending on its configuration.
