I am trying to delete an existing database in SQL Server 2005. My first attempt produced the following error:
5030: The database could not be exclusively
locked to perform the operation.
I have since killed all processes that are accessing the database. I have also removed the replication subscription that it had previously been involved in.
Any thoughts on what else that could be holding the lock on it besides SQL Server processes and replication?
Update: I restarted the server, and that fixed it. I was trying to avoid that, since this is a production server, but hey what can you do?

A production server in which so many connections use the database yet you want to drop it?
None the less, how to kick out everybody from the database:
USE [dbname];
ALTER DATABASE [dbname] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
Then drop the database:
USE [master];
DROP DATABASE [dbname];
There is still a very small window of opportunity between the USE [master];
and DROP DATABASE ...
where some other connection can grab the 1 single allowed lock on the database, but it usually not worth working around that.

I hate to say it, but a quick solution is to restart the system, make sure the sql server server service is not started, then you should be able to delete.
Also, is IIS stopped if you db is connected to a web ap?

You don’t happen to know if anyone left a transaction in an uncompleted rollback state (or otherwise uncompleted)? Might as well check the locks list, too.

In the management studio, goto Management->Activity Monitor (right click) -> View Processes. That will give you a full list of everything running, you can sort the list by Database to see what is still attached, and you can also kill any connections. It’s easy to end up with orphaned connections that will prevent you from getting the exclusive access that you need.

No One else should be using the DB, including yourself.

Why would we make a deleted DB to multi user mode.
ALTER DATABASE dbName SET MULTI_USER WITH ROLLBACK IMMEDIATE

To avoid this error, use the T-SQL script below in the master database. Make sure to run this (and modify the @dbname) for each database you are running the ALTER DATABASE command in.
«The database could not be exclusively locked to perform the
operation»
This «connection killer» script will work if Windows has established JDBC connections to the database. But this script is unable to kill off JDBC connections for Linux services (e.g. JBoss). So you’ll still get that error if you don’t stop JBoss manually. I haven’t tried other protocols, but please comment if you find out more information as you build new systems.
USE master;
DECLARE @dbname sysname
Set @dbname = 'DATABASE_NAME_HERE-PROD'
Declare @spid int
Select @spid = min(spid) from master.dbo.sysprocesses
where dbid = db_id(@dbname)
While @spid Is Not Null
Begin
Execute ('Kill ' + @spid)
Select @spid = min(spid) from master.dbo.sysprocesses
where dbid = db_id(@dbname) and spid > @spid
End

This error normally occurs when your database is in Multi User mode where users are accessing your database or some objects are referring to your database.
First you should set the database to single user mode:
ALTER DATABASE dbName
SET SINGLE_USER WITH ROLLBACK IMMEDIATE
Now we will try to delete the database
delete DATABASE ...
Finally set the database to Multiuser mode
ALTER DATABASE dbName
SET MULTI_USER WITH ROLLBACK IMMEDIATE

When you want to rename your database and you hit the error below, you need to set the database to Single User Mode. After you rename your database, then you set the database back to Multi-User mode.
Msg 5030, Level 16, State 2, Line 1
The database could not be exclusively locked to perform the operation
Follow the steps below to rename your database.
- Set the database to single-mode
ALTER DATABASE OLD_DBName SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
2. Rename the Database
ALTER DATABASE OLD_DBName MODIFY NAME = NEW_DBNAME;
3. Set the database to Multi-user mode
ALTER DATABASE NEW_DBNAME SET MULTI_USER WITH ROLLBACK IMMEDIATE;

Thats because someone else is accessing the database.. Put the database into single user mode the rename it.
USE [master]; GO ALTER DATABASE foo SET SINGLE_USER WITH ROLLBACK IMMEDIATE; GO EXEC sp_renamedb N'foo', N'bar';

If you are facing this error : “The database could not be exclusively locked to perform the operation. (Microsoft SQL Server, Error: 5030)” when you try to rename SQL server database you need to temporary switch from Multi User mode to single user mode, then rename the database and then set it back to Multi user mode.
Do it step by step.
ALTER DATABASE dbName
SET SINGLE_USER WITH ROLLBACK IMMEDIATE
ALTER DATABASE dbName MODIFY NAME = dbNewName
ALTER DATABASE dbNewName
SET MULTI_USER WITH ROLLBACK IMMEDIATE
So, if you are trying to change the collation of a database and getting error 5030, this is much likely because you cannot change the collation of a database when it is in Multi_User mode. In this case, you should try to run the following query.
-- the following line sets the database to "Single User" mode ALTER DATABASE DBNAME SET SINGLE_USER WITH ROLLBACK IMMEDIATE -- the following line sets the new collation ALTER DATABASE DBNAME COLLATE COLLATIONNAME -- the following line sets the database back to "Multi User" mode ALTER DATABASE DBNAME SET MULTI_USER
DBNAME: Database name
COLLATIONNAME: New collation’s name. E.g.: Latin1_General_CI_AI
