scheduling SQL server to restart

Hi All,
I would like ot know that how can i schedule SQL server services to restart every three day Please?
thanks

How about scheduling the job restart using Task Scheduler of Windows itself? I am just wondering. May be there is a better solution than this.

You have to write a batch file using NET START and NET STOP commands..

I don't think there is way to schedule every three days using nt scheduler...

There is using some batch scripting... Keep in mind you can always issue an AT command... that runs under the System account unless the account is specifically configured in Task Scheduler. You could write a script that restarts SQL Server and then reschedules itself.

Do you mind me posing the question why you would do something like that ???
If it is sqlserver consuming to much memory, you can restrict it if that is what you realy want ?! (sp_configure 'max server memory'..)
By restarting sqlserver, it needs to rebuild its non-persistend structures and statistics, (re)do all the costly I/O operations because it will have to read all the data from disk in stead of from its buffers. All the connections will have to be redone, ...
If you just want to rollover the sqlserver-serverlog-file, you may want to use DBCC errorlog. Schedule it with sqlagent.

if you are running a default instance of sqlserver :
from books online:
net stop mssqlserver
Stops an instance of SQL Server either remotely or locally if you are running the Microsoft Windows NT® 4.0 or Windows® 2000 operating systems. To stop a named instance of SQL Server 2000, you must enter net stop mssql$instancename from the command prompt.
Start an instance of SQL Server or the SQL Server Agent service from a command prompt by typing:
net start mssqlserver or sqlservr, or net start SQLServerAgent or by running SQLSERVR.EXE. If you are referring to a named instance of SQL Server, you must specify mssql$instancename or SQLAgent$instancename.
Don't forget to start SQLAgent !! if you use sqlserver jobs !

but how can i schedule that so it can run automatically. Also Agent is dependent on that.

Just for Mohammed Uddin. Your statement, "
I don't think there is way to schedule every three days using nt scheduler...",
is too fast. Think about why we cannot?

SQLRep:
create a *.cmd file(notepad) that contains these line items:
net stop mssqlserver
net start mssqlserver
net start SQLServerAgent
then go to Control Panel >>Scheduled Tasks for that file; then fiddle with the schedule to your hearts content.

net stop mssqlserver /Y
Otherwise it'll hang at the prompt to also shut down SQL Server Agent if that is running.

If I am not mistaken we can't schedule the job every three days... there is a option for daily weekly and so on.. but without writing any widow script I don't think we can schedule every three days...Task scheduler is not flexible enough like sql job scheduler...
Here is what I can think...
1. Create a batch file (test.bat) using the using net start command...
net stop sqlserveragent
net stop mssqlserver
net start mssqlserver
net start sqlserveragent
2. Create a sql job using the following code... change the time and day as you needed..
declare @sql sysname
declare @machineName sysname, @Time Varchar(5), @day sysname
select @machineName = CONVERT(Varchar(20), SERVERPROPERTY('MachineName')),
@Time = '10:50' , -- convert(Varchar(5), getdate(),14),
@day = datename(dw,getdate())
select @machineName
select @sql = 'at \\'+@machineName+' /delete /yes'
EXEC MASTER..XP_CMDSHELL @SQL
select @sql = 'at \\'+@machineName+' '+@Time+' /every:'+@day+' "c:\test.bat"'
select @sql
EXEC MASTER..XP_CMDSHELL @SQL
3. Schedule the job create in step2 every three day or as needed...

Should also note that if applications running against sql server that restarting the services may cause a conflict when restarted.
Example: if an applications is running a transaction through Com + (MSDTC) and SQL Server is shut down this may cause additional problems with the application or SQL Server once restarted. In this cause of course could be resolved by also running the NET STOP MSDTC and NET START MSDTC
