You might need to reboot your DB instance, usually for maintenance reasons. For example, if you make certain modifications, or if you change the DB parameter group associated with the DB instance, you must reboot the instance for the changes to take effect.
rds_reboot_db_instance(DBInstanceIdentifier, ForceFailover)[required] The DB instance identifier. This parameter is stored as a lowercase string.
Constraints:
Must match the identifier of an existing DBInstance.
A value that indicates whether the reboot is conducted through a Multi-AZ failover.
Constraint: You can't enable force failover if the instance is not configured for Multi-AZ.
svc$reboot_db_instance( DBInstanceIdentifier = "string", ForceFailover = TRUE|FALSE )
Rebooting a DB instance restarts the database engine service. Rebooting a DB instance results in a momentary outage, during which the DB instance status is set to rebooting.
For more information about rebooting, see Rebooting a DB Instance in the Amazon RDS User Guide.
