I have been doing SQL Server DR testing using the following process.
We are use a replication package that mirrors the SQL data drives from the Source SQL Server across to the DR SQL Server.
As our applications are connecting to the SQL data via ODBC or JDBC I have basically taken the origin server out of the network and renamed the DR server with the original server name and also changed it's IP address to that of the origin server.
I then restart SQL Services on the DR server and allow the applications to reconnect.
This has been a bit messy at times, with name resolution issues as well as a number of server reboots. Not to mention the fact that we have to repeat the process when switching back to the initial server.
Does anyone have a better switch over process ?
