What is typically adjusted to meet the requirements for changing retention time in the Automatic Workload Repository?

The correct answer is the setting for snapshots. In the context of the Automatic Workload Repository (AWR), snapshots are taken at regular intervals to capture the state of the database system. These snapshots are crucial for performance tuning and troubleshooting because they provide a historical record of database performance during specific time frames.

When adjustments are needed to change the retention time for how long these snapshots are kept, it is primarily the snapshot settings that determine the intervals at which they are collected and how long they are retained. By modifying these settings, database administrators can control the amount of historical performance data available in the AWR, ensuring that it meets organizational requirements or compliance needs.

While connection limits, session timeouts, and database parameters play significant roles in the overall performance and configuration of the database system, they do not directly affect the retention time of AWR data. Therefore, adjusting snapshot settings offers a focused approach to managing the retention of performance information collected by the AWR.
