Shutting down SQL server before a  powerfailure

Posted on 2001-09-05

I have a UPS software which allows me to run a script (.bat) in NT/Windows 2000 just before shutting down windows in the event of a power failure.

1. If I shut down windows without bringing MSSql down, does it cause problems? Or is SQL brought down safely by NT itself before shutting down?

2. What command can I use in the batch file to bring down SQL safely?

Normally, SQL Server runs as a service, and is requested by Windows to shutdown whenever windows goes down...
Now if you want to stop SQL Server by bat file, simply put this command:
NET STOP MSSQLSERVER

This will stop all the services related to SQL Server too:
MS SQL Server agent, for example, and any other service that marked sqlserver as dependency

If the SQLServerAgent is started, and you execute NET STOP MSSQLSERVER, it's gonna ask you to also shutdown the SQL Server Agent service, but if the process is in background, you wont'n be able to answer the question and it won't work.
  First execute NET STOP SQLSERVERAGENT (if it is already sttoped it will give an error but it will continue) and then NET STOP MSSQLSERVER.

   But the Server it selfs shutdowns all the services before a normal shutting down. If a power failure happens, then the server won't shutdown ok, but when it raise up, rolls back all the uncommited transactions and rolls forward all the commited transactions.
 
  In this way, every finished transaction is like it was before power failure, and all the transactions that where running when the power failure happens, is like they never happened.
