6. The modifications take effect only after you apply the parameter template to DB instances. For details, see Applying a Parameter Template.
7. View the status of the DB instance to which the parameter template is applied.

   If the DB instance status is Parameter change. Pending reboot, a reboot is required for the modifications to take effect.

   • The DB instance reboot caused by instance class changes will not make parameter modifications take effect.
   • If you have modified parameters of a primary DB instance, you need to reboot the primary DB instance for the modifications to take effect. (For primary/standby DB instances, the parameter modifications are also applied to the standby DB instance.)
   • If you have modified parameters of a read replica, you need to reboot the read replica for the modifications to take effect.
