dbInstanceClass

The new compute and memory capacity of the DB instance, for example db.m4.large. Not all DB instance classes are available in all Amazon Web Services Regions, or for all database engines. For the full list of DB instance classes, and availability for your engine, see DB Instance Class in the Amazon RDS User Guide or Aurora DB instance classes in the Amazon Aurora User Guide. For RDS Custom, see DB instance class support for RDS Custom for Oracle and DB instance class support for RDS Custom for SQL Server.

If you modify the DB instance class, an outage occurs during the change. The change is applied during the next maintenance window, unless you specify ApplyImmediately in your request.

Default: Uses existing setting

Constraints:

• If you are modifying the DB instance class and upgrading the engine version at the same time, the currently running engine version must be supported on the specified DB instance class. Otherwise, the operation returns an error. In this case, first run the operation to upgrade the engine version, and then run it again to modify the DB instance class.
