Hi experts,
Someone taught me a technique to run checkdb with MAX_DOP > 1 using resource governer. I tried it but failed. what's wrong?
---
CREATE RESOURCE POOL [zCHECKDB] WITH(min_cpu_percent=0,
max_cpu_percent=100,
min_memory_percent=0,
max_memory_percent=100,
AFFINITY SCHEDULER = AUTO
)
GO
CREATE WORKLOAD GROUP [ZCHECKDB] WITH(group_max_requests=0,
importance=Medium,
request_max_cpu_time_sec=0,
request_max_memory_grant_percent=25,
request_memory_grant_timeout_sec=0,
max_dop=16) USING [zCHECKDB]
GO
CREATE FUNCTION dbo.classify_zCHECKDB() RETURNS sysname
WITH SCHEMABINDING AS
BEGIN
DECLARE @grp_name sysname
IF (APP_NAME() LIKE '%Studio%')
SET @grp_name = 'zCHECKDB'
RETURN @grp_name
END;
GO
ALTER RESOURCE GOVERNOR WITH (CLASSIFIER_FUNCTION= dbo.classify_zCHECKDB);
GO
ALTER RESOURCE GOVERNOR RECONFIGURE;
GO
dbcc checkdb('TCD')
