+###### Important
+
+For Amazon RDS for Oracle DB instances, you will see the `SupportsCertificateRotationWithoutRestart` flag of the DB engine versions marked as `FALSE`. However, Amazon RDS for Oracle DB instances do NOT require restart, but the database listener is restarted during the server certificate rotation. Existing database connections are unaffected, but new connections will encounter errors for a brief period while the listener is restarted. If you want to manually rotate the server certificate, use the [ apply-pending-maintenance-action](https://docs.aws.amazon.com/cli/latest/reference/rds/apply-pending-maintenance-action.html) AWS CLI command.
