Remarks

To delete a workload group or resource pool, select the row for the workload group or resource pool, right-click the pointer at the beginning of the row, click Delete, and then click OK.

To move a workload group, select the row for the workload group, right-click the pointer at the beginning of the row and then click Move to, specify a new location, and then click OK.

When you click OK after adding, deleting, or moving a workload group or resource pool, the ALTER RESOURCE GOVERNOR RECONFIGURE statement is executed.

Note

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.
