# ProcessorFeature
<a name="API_ProcessorFeature"></a>

Contains the processor features of a DB instance class.

To specify the number of CPU cores, use the `coreCount` feature name for the `Name` parameter. To specify the number of threads per core, use the `threadsPerCore` feature name for the `Name` parameter.

You can set the processor features of the DB instance class for a DB instance when you call one of the following actions:
+  `CreateDBInstance` 
+  `ModifyDBInstance` 
+  `RestoreDBInstanceFromDBSnapshot` 
+  `RestoreDBInstanceFromS3` 
+  `RestoreDBInstanceToPointInTime` 

You can view the valid processor values for a particular instance class by calling the `DescribeOrderableDBInstanceOptions` action and specifying the instance class for the `DBInstanceClass` parameter.

In addition, you can use the following actions for DB instance class processor information:
+  `DescribeDBInstances` 
+  `DescribeDBSnapshots` 
+  `DescribeValidDBInstanceModifications` 

If you call `DescribeDBInstances`, `ProcessorFeature` returns non-null values only if the following conditions are met:
+ You are accessing an Oracle or SQL Server DB instance.
+ Your Oracle or SQL Server DB instance class supports configuring the number of CPU cores and threads per core.
+ The current number CPU cores and threads is set to a non-default value.
