Uninstall SQL ServerThere may be occasions when you want to uninstall SQL Server. Some of the reasons for uninstalling include:
We will first look at how to uninstall SQL Server and then look at rebuilding the master database.
Step by Step Guide
To uninstall an existing installation of SQL Server 7.0 or SQL Server 2000 (default or named instance):
You should now have managed to uninstall SQL Server completely.
Rebuilding the Master Database
If your master database has become corrupt then instead of reinstalling SQL Server you can use the rebuildm utility that come with SQL Server.
I WOULD ENSURE YOU HAVE THE NECESSARY BACKUP FILES AND SCRIPTS NECESSARY TO REBUILD ALL SQL SERVER OBJECTS INCLUDING USER DATBASES BEFORE CARRYING OUT THE FOLLOWING MASTER REBUILD PROCEDURE.
Once you have confirmed you have all the backup files and SQL scripts needed to restore to your SQL Server instance when the rebuild of the master has completed you can begin the rebuild of the master database procedure. The following tutorial will take you through rebuilding the master database for your SQL Server 2000 installation - the process is similar for SQL Server 7 but may vary for other versions:
Once this has completed you will need to restore all other user databases and other objects that will now be missing since the master database has been restored, in affect you have rebuilt your SQL Server.
I would recommend, especially for your production environments, that you keep a detailed backup recovery plan in the event of server failure, this will include Backup files and transaction logs and scripts that can be used to recreate logins and other objects needed on your server, that falls outside the scope this article but there are other articles on this site that can help you formulate a backup recovery plan. Read much more about performing SQL Server DBA functions in another section of this site.
This article has talked about how to uninstall SQL Server and rebuilding the master databases in the event of failure. SQL Server today is a stable and reliable platform, but I can’t emphasise enough the importance of being familiar with these procedures, you never know when you will have to carry out the process in real live environment.
