Hi,
We have configured two SQL Server 2005 in a cluster (without Witness).
We have severals ASP (using ADO) that are connecting to SQL Server 2005 with SQL Native Client in a DSNLess connection String :
driver={SQL Native Client}; server=MAIN\MAIN; Failover Partner=BCKUP\BCKUP; uid=log;pwd=pwd;database=MyBase
When using this connection string, the connection to MAIN is alrigth, but when we simulate a unavailability situation on "MyBase" or on the entire MAIN instance, the new connection are joining the MAIN and not the BCKUP SQL Server.
We tryed several Connection Strings including Failover_Partner, Initliag Catalog instead of database... but no one succed in joining the BCKUP SQL Server.
I precise that the DNS on the PC that connect to SQL server is configured and both MAIN and BCKUP are resolved in command line or in explorer.
Is there an other driver that must be used, or is there an other parameter to set in the connection string ?
Regards.
Failover Partner is used in the case of database mirroring, not for the case of cluster. Check here: http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx
Cluster is transparent to client, i.e., client should be able to connect to the server without knowing the server is a cluster or not. In cluster case, use "server=your_virtual_server_name" in the connection string.
