Hi All, Sql server 2012 standard edition We are using two database servers, databasesserverI is connected for application to store data. and databaseserverII using to replication data from datbaseserverI. Here databaseserverII is not available for application users. Now databasesserverI is connected and working with application to store data. Is there any chance to connect application to databaseserverII automatically when databasesserverI is not available(etc:- server down or server running slow) to application Could you explain how to write connection string's to satisfy above scenario. Thanks In Advance.
