NoteNote

When you change a Resource Governor configuration using Transact-SQL statements, you must explicitly execute the ALTER RESOURCE GOVERNOR RECONFIGURE statement in order to apply the changes. For more information, see ALTER RESOURCE GOVERNOR (Transact-SQL).

You can determine whether there is a configuration pending by querying the sys.dm_resource_governor_configuration dynamic management view to get the current status of is_configuration_pending.

If the create or reconfigure operation for the resource pool or workload group fails, a summary error message appears below the title of the property page. To see a detailed error message, click the down arrow on the error message.
