For details on the description of parameter group statuses, see Parameter Group Statuses.
After you reset the parameter group, you need to view the status of the DB instance in the DB instance list. If the status is
, you must reboot the DB instance for the reset to take effect. Rebooting is always required after resetting parameter groups under the following circumstances:
- The DB instance type is primary/standby. In this case, the standby DB instance will also be changed accordingly after the reboot.
- The reset parameter group applies to a read replica.
