Hi There,
Having some problem with MultiSubNet AG failover re-connection using SQL JDBC driver 4. Details given below.
SETUP:
We have a three node 2012 Windows Server Cluster, on top it we 2012 SQL Sever AlwaysOn Availability Group.
Two nodes are in one subnet and other in a different subnet to make this as a multisubnet AlwaysOn AG.
An AG Listener is configured with a DNS name and two VIP assigned (For two subnet) to it. We were able to failover from one subnet to other using the SQL Studio successfully.
NEED:
We have a java application which will be connected to AG Listener name. In case of failover, automatic re-connection to DB/AG Listener name should happen.
For this we use "sqljdbc4.jar" and added 'multiSubnetFailover=true' in our connection string. The connection String is given below.
cURL="jdbc:sqlserver://testsqlag:1433;databaseName=SalesDB;multiSubnetFailover=true;loginTimeout=200;applicationName=MyApp";
THE PROBLEM:
In case of AG failover, driver is not trying to re-connect to the other AG Listener name in other subnet. Not sure how to make it work.
Is this supported in SQL Server 2012 ?
Thanks,
Krishna.
