使用EF的asp.net应用程序无法与SQL Server进行数据库镜像

Question

I have database mirroring setup to work with the production database for my asp.net application. When the system fails over to the mirrored database, the application crashes because the connection string is invalid.

If the failover is dependent on a connection string, what kinds of changes do I need to make to my application in order to ensure that it can fail over without my manually changing the connection string?

Do I put exception handling behavior around the EF code where it automatically changes its connection string?

Answer 1

Depending on the type of failover you have set up, I believe there is a connection string property that you can specify the failover DB.

Data Source=myServerAddress;Failover Partner=myMirrorServerAddress;Initial Catalog=myDataBase;Integrated Security=True;
