Hi All,

 

I set up AG in SQL Server 2016 where i can read and write data in Primary node but same time i can not read data from secondary replica. 

Is there any way, sqL query or GUI to make secondary replica read only.

You can do that from SSMS GUI, drill down the the Avaialbility group then right-click properties. On the General Page there is a section for Availability Replica where all the replica is listed. On the column Readable Secondary you can change it to the setting you want.  Or by TSQL:

 

ALTER AVAILABILITY GROUP [AGName] MODIFY REPLICA ON N'InstanceName' WITH (SECONDARY_ROLE (ALLOW_CONNECTIONS = READ_ONLY));

 

You can change read_only to the setting you would like.
