Managing jobs in always on Availability groups

Managing jobs in always on Availability groups

DBA has Setup Always on Availability Groups between 2 servers and has a Script that wanted to put in Job and run the job only on primary at any time..(one active and one secondary)

USE MASTER

GO
DECLARE @ServerName NVARCHAR(256)  = @@SERVERNAME
DECLARE @RoleDesc NVARCHAR(60)

SELECT @RoleDesc = a.role_desc
    FROM sys.dm_hadr_availability_replica_states AS a
    JOIN sys.availability_replicas AS b
        ON b.replica_id = a.replica_id
WHERE b.replica_server_name = @ServerName

IF @RoleDesc = 'PRIMARY'

BEGIN
USE TestAG
Insert into CheckAvailabilityRoleJobs(InsertDate,ServerName,RoleDescription)
SELECT GETDATE(),@@SERVERNAME, a.role_desc
FROM      sys.dm_hadr_availability_replica_states AS a
JOIN sys.availability_replicas AS b ON b.replica_id = a.replica_id
where   b.replica_server_name=@@SERVERNAME
END

ELSE

BEGIN

      RETURN
END 

DBA wanted to keep this job running 24X7 on both servers, but insert happens only on Primary at any time , in secondary the JOB exits with out actually inserting...

the script  is running good on PRIMARY, but when DBA try to run on SECONDARY it is failing ...

the script should actually exit on SECONDARY after checking Primary or not but it is trying too connect TESTAG database which is not accessible on secondary

Msg 976, Level 14, State 1, Line 16
The target database, 'TestAG', is participating in an availability group and is currently not accessible for queries. Either data movement is suspended or the availability replica is not enabled for read access. To allow read-only access to this and other databases in the availability group, enable read access to one or more secondary availability replicas in the group.  For more information, see the ALTER AVAILABILITY GROUP statement in SQL Server Books Online.

Answer:

DBA found out that ...secondary server should be Readable ..it is not possible to run jobs/check in secondary servers  which are not readable
