This dynamic management view shows the in-memory configuration. To see the stored configuration metadata, use the corresponding catalog view.
The following example shows how to get and compare the stored metadata values and the in-memory values of the Resource Governor configuration.
USE master; go -- Get the stored metadata. SELECT object_schema_name(classifier_function_id) AS 'Classifier UDF schema in metadata', object_name(classifier_function_id) AS 'Classifier UDF name in metadata' FROM sys.resource_governor_configuration; go -- Get the in-memory configuration. SELECT object_schema_name(classifier_function_id) AS 'Active classifier UDF schema', object_name(classifier_function_id) AS 'Active classifier UDF name' FROM sys.dm_resource_governor_configuration; go
Requires VIEW SERVER STATE permission.
