Hi guys, hope you can help. I have a 2012R2 always on SQL Cluster setup. which has been working fine.
so when running my application from SQL02 (primary) , the application works fine, but when we manually failover to SQL01
The application stops working (web based application). there doesn't appear to be anything in the logs to indicate any issues,
If I changed the connection string for the application to point directly to the sql instance, rather than the listener, the web app works fine, so it sort of points to the listener not working on the secondary node.
There are two instances of SQL on this install, the default instance which are hosting multiple databases works fine, on both primary and secondary nodes. so I am scratching my head, I don't see any errors, its like its just not listening on when failed over. yet the dashboard reports no issues, sql logs no issues.
any help would be appreciated.
Thanks
Mark
