Recently I got the error while trying to rename an existing database name by following this articles. The error was: The database could not be exclusively locked to perform the operation.

The error comes because other users using the same database. So we should make the database so that it can be used by yourself only. And after rename you can change back so that other users can use this.

So to rename the db I need to follow the below 3 steps sequentially and the error gone.

ALTER DATABASE TestDB
SET SINGLE_USER WITH ROLLBACK IMMEDIATE

ALTER DATABASE TestDB
Modify Name = TestDBNew ;

ALTER DATABASE TestDBNew
SET MULTI_USER WITH ROLLBACK IMMEDIATE

Now you should be able to successfully rename the db as well as you should not get any error.
