What is the method for cleaning up oracle audit logs?

There are several ways to clean the Oracle audit logs: 1. Utilize Oracle’s audit log cleaning tool, such as the `AUDIT_PURGE` stored procedure, that is specifically designed for this purpose. Schedule regular cleanings by creating a timed task calling the stored procedure every so often. 2. Manually delete audit log files that are stored in the directory specified by the `AUDIT_FILE_DEST` parameter in the database, usually located in the `$ORACLE_HOME/rdbms/audit` directory. Always back up these files before deleting to preserve them for future audits and investigations. 3. Adjust audit log parameters to control the amount generated. Modify parameters like `AUDIT_TRAIL` (specifying log storage location) and `AUDIT_SYSLOG_LEVEL` (determining log detail level) to reduce the amount of audit logs created. 4. In addition to Oracle’s tools, consider using third-party tools for more flexible and customized audit log cleaning functionalities. Before cleaning the logs, ensure to understand relevant legal, compliance, and security requirements for adherence. Also, it is advisable to back up audit logs to guarantee data safety and availability prior to cleaning.
