I’m not sure if there is such a question that I can’t seem to find. I have a clustered instance named FCSQLSRV. Because this is the virtual name so I can’t create an alias for the clustered instance. I have another SQL Server database server (B) using the default name instance (MSSQLSERVER). What I want is to create the alias for the server B using the same clustered instance name. The reason is I just want to switch my application (that is connecting to the server B) to use the clustered instance.
You can create a client alias on the application server. You will have to run CLICONFG.EXE on the client, click add on the alias tab, click TCP/IP add the server alias B and set the connection paramters to be FCSQLSRV after this all connections to server B from that client/application server will be forwarded to FCSQLSRV If your application is 32bit you will also have to do the same for the 32bit registry and run %systemroot%syswow64cliconfg.exe
