- Reboot server
- Make sure that SQL Server and related services are started.
- Start application/services that connect to the SQL Server instance
- Certify that everything works well on the Test server after the installation of patches is completed.
- You need to get acceptance by all affected parties (i.e., IT users, application owners, etc.).
- If there is a problem, you will have to troubleshoot in order to resolve it.
- In the unfortunate case where you cannot resolve the problem, as a last resort, you can follow a rollback procedure which involves the following but is not limited to:
- Uninstall the patch(es) previously installed.
- Restore the system databases as well as the resource database (both data and log files)
- Reboot the server.
- Check if everything is back to normal, that is the state of SQL Server just before the patching started
- If there is still a problem, restore the server (OS) from the backup taken prior to starting the process.
- Check if all user databases are OK. If not, restore them from the backup taken prior to starting the patching process.
- Check again if everything OK.
