The audit data retention feature helps you to manage the quantity of audit data in the audit table in the Oracle Data Safedatabase.
Activity Auditing collects audit records stored in the audit trails on selected target databases and batch copies the data into its own audit table. This audit table can become large. To keep its size manageable, you can configure the audit data retention policy to retain audit data for a specified number of months. For example, if you specify 8 months, Oracle Data Safe stores audit data up to 8 months back and automatically deletes any data that is older than 8 months. The minimum retention period is 1 month. The maximum is 12 months.
When you change the retention period, a new retention policy is applied to the incoming data immediately. The change does not affect the existing tablespaces that adhere to the previous retention policy.
A regional Oracle Data Safe service is allowed to collect up to 1 million audit records for each target per month for free. If it reaches the limit, you can configure the service to stop collecting audit data or pay to continue. The default is to continue. On the Settings page, you can set a global preference for all targets to continue collecting audit data after the limit is reached, or you can select particular targets.
