SQL Jobs on Always On

,

Either we can execute this script directly or we can use this in SQL Agent job and schedule it.

This script will verify the SQL Server instance and enabled/disabled the jobs based on the replica server state.

-- Enabling/Disabling SQL agent jobs on AO instances.
-- <Raghavender Chavva>
-- <20th March,2014>
-- <This query is not suitable for SQL Server versions which are below SQL Server 2012 and SQL Servers which are not in Always On>
-- < This script will verify the SQL Server instance and enabled/disabled the jobs based on the replica server state.>

-- Step 1: -- ---checking instance replica status (here Primary)

if((select role_desc from sys.dm_hadr_availability_replica_cluster_states arc,sys.dm_hadr_availability_replica_states ars where arc.replica_id=ars.replica_id and arc.group_id=ars.group_id and replica_server_name=(select @@SERVERNAME))='PRIMARY') 

begin

-- Step 2: -- Colleting the job names

select name into #temp from msdb..sysjobs where enabled=0 and name not in('_SQL_BackupTranAll','_SQL_BackupAll','syspolicy_purge_history')


-- select * from #temp

declare @jobname varchar(200)
DECLARE db_cursor CURSOR FOR 
SELECT name
FROM #temp
OPEN db_cursor  
FETCH NEXT FROM db_cursor INTO @jobname  


--- Step 3: Enabling the required jobs.

WHILE @@FETCH_STATUS = 0  
BEGIN  
       print 'Job name in primary '+@jobname 
        print 'exec msdb..sp_update_job @job_name = '''+@jobname+''', @enabled = 1' –- Enabling the jobs
       FETCH NEXT FROM db_cursor INTO @jobname  
END  

CLOSE db_cursor  
DEALLOCATE db_cursor
drop table #temp
END

-- Step 4: -- ---checking instance replica status (here Secondary)

else
if((select role_desc from sys.dm_hadr_availability_replica_cluster_states arc,sys.dm_hadr_availability_replica_states ars where arc.replica_id=ars.replica_id and arc.group_id=ars.group_id and replica_server_name=(select @@SERVERNAME))='SECONDARY')

–- Step 5:  Colleting the job names

begin
select name into #temp1 from msdb..sysjobs where enabled=1 and name not in('_SQL_BackupTranAll','_SQL_BackupAll','syspolicy_purge_history','_SQL_DBCCCheckDB','_SQL_DbccCheckFG','_SQL_DbccCheckTable','_SQL_DbccCheckCatalog')
--select * from #temp
declare @jobname1 varchar(200)
DECLARE db_cursor CURSOR FOR SELECT name FROM #temp1
OPEN db_cursor  
FETCH NEXT FROM db_cursor INTO @jobname1 

–- Step 6: Disabling the jobs

WHILE @@FETCH_STATUS = 0  
BEGIN  
       print 'Job name in secondary '+@jobname1 
        print 'exec msdb..sp_update_job @job_name = '''+@jobname1+''', @enabled = 0'


       FETCH NEXT FROM db_cursor INTO @jobname1  
END  

CLOSE db_cursor  
DEALLOCATE db_cursor
drop table #temp1
