Killing User Connections

Is there a way to kill all user connections to a database using T-SQL?
Thanks!
I am having a problem with an application that does not kill timed out connections. This is normally not an issue, but when something causes the timed out connections to build up, it stops the frontend from working correctly. The frontend developers are trying to figure out how to change their code to check for and drop timed out connections at the application. Until then, I need a way to check for timed out connections at the database and drop them there via a job that will run every 10 minutes or so. I have to make sure that only timed out connections are dropped and not active ones. Any suggestions?

Develpers complain that Sql server is slow
We running 4 databases about 400 MB each.(hotel reservations ...)
Buffer cache ( 99.8) but sometimes it goes down to (62.0)
memory configuration Dynamic
Do we really need more memory for 50 users or what should I check in the first place ?
Thanks
We are using SQL Server 7.0. Can anyone tell me the difference between setting max connections to 150 versus setting it to 0 for unlimited. We have an application that was running slow with the 150 connections set. We changed it to 0 for unlimited and now the application flies.
Can anyone explain this? Does SQL Server do something different with these settings?
Thanks!
I'm locked out of my SQL server because user connections are set at '5' and apparently there are already '5' users connected.
So.. I can't login as SA or anyone to change the option. We've rebooted, disconnected from the network, and still '5' users seem to be connected.
What could be causing this.. Or how can I override the connections without logging in.
I'm running SQl Server 7.0 SP1.
Currently the number of simulteneous user connections is set to 0 (0=unlimited).
But one of remote users when trying to connect to the server is getting sql error message that "There are more then 10 users connected".
Should I change "user connections" server configuration?
Thank you

Hi guys,
Help me please to clarify following situation.
My application has 20.000 users.
How many simultaneously user connections should I'll set?
Thanks,

I am trying to shrink my tempdb using the following sql 6.5 commands:
sp_dboption 'tempdb', 'single user', true
dbcc shrinkdb(tempdb)
I get the following message: "Attempt to set 'tempdb' database to single user mode failed because the usage count is 3. Make sure that no other users are currently using this database and rerun CHECKPOINT."
When I do a 'sp_who active' it returns about 5 spids but they are things like Mirror Handler, Lazy Writer, Checkpoint Sleep, RA Manager, and Select. I am not able to 'kill' the spids. I get 'Only users processes are able to be killed.' How do I identifiy the 3 users that sql is saying are connected to the tempdb database? And how do I remove the 3 users?
Thanks in advance.

Hi all!
In SQL 6.5, if I increase my user connections, should I also increase the amount of RAM allocated to SQL?
Any help would be appreciated.
Thanks

I need to know the number of client licences that i require for a SQL Server. I want to monitor the
Server for a period of a week or so to find out the max..no of user connections during that time
so that i can fix the no. of user connections parameter.
i have tried using the foll Perf monitor counters :
No of open user connections
Client Count
Max Client Count
Client Limit
and am still confused about the numbers.
Can anyone throw some light on the difference in these counters and which one do i go by for
calculating my licenses .
Thanks
I am in the process of installing 7 remote desktop computers that are furnishing data to a SQL server. We will also have 40-50 Managers/Supervisors who will have access to the database for information retrieval. Are there any tools available that would allow me to monitor who is connected to the Server? My main interest in monitoring are the 7 desktops which are permanently connected to the database. Until we have some history, I would like to make certain that we can maintain a good connection between the desktops and the server

I need to perform a daily restore and have to manually kill multiple
user connections, its very time consuming. Is there an easier way?
Id be grateful if you can help me!
Many thanks,

We have a production server that is configured to 100 user connections.
Without any reason, the maximum connections had been exceeded and users
can no longer access the sql. But if you sp_who , it displayed only
4 user connections. Since, I have an open connection before this error
happens, i was able to execute sp_who. This happened 4 times since we
installed the sql server. the version is 6.50.422 sp5a with hotfix.
To all gurus out there, can you give light into this problem?
Thanks in advance.
To increase user connections in SQL 6.5 do I have to first increase the memory configuration numbers?
Current memory config is at 8192.
Recently, my SQL Server has started getting:
"Unable to connect. The maxinum of '100' configured user connections are already connected. System Administrator can configure to a higher value with sp_configure."
The server has to be rebooted to recover.
What's odd is that this occurs during the weekend when only about 5-8 connections are used by various system processes. I can't tell yet what is sucking up the connections.
We use SQL 6.5 sp4 on NT4.0 sp3 for DEC Alpha. We are also using SQL Mail, Seagate Backup (with SQL drivers) and some cgis that talk to the database.
Any thoughts would be appreciated.

I did something stupid. I was having a problem with my application of trusted connections exceeding 15. I changed the user connections to 30 without uping the server memory configuration. Now I am out of memory and can't establish a connection with the server to up the memory configuration. I don't want to have to reinstall sql 6.5 and loose my existing data. I am on a Netfinity server with 512 megs of memory. Any suggestions? And of course our NT tape backup unit is not set up for sql backup.
Also does 30 connections and 128 megs of sql memory sound ok for a non dedicated server. About 25 users connecting to the database at any given time?
We are having a problem with the maximum number of user connections to sql. Currently we have a max of 500 connections and we are unable to connect to sql because the max number has been exceeded. The sql logs are flooded with repeated error messages about the user conncetions being maxed out.
Anyone has an idea why this could be happening? Also, can it be fixed by rebooting the server?
Thanks
Newbie here.I've got my database set up in SQL 2000, and have started an Access adpfor a front end. I have 10 licenses, and at the moment the onlyaccesses are the server through Remote Desktop and one person into theADP. I started getting ODBC timeout errors when running a complexquery, so I started poking around. In the logs there's messages sayingthe maximum of 10 user connections has been reached, over and overagain. I'm not even certain that these problems are related, but itdoesn't look good.Why are all 10 connections used when there's only the server and oneclient? No one else has access to this server. And how can I stop theODBC timeout? That paticular complex query is the whole jsutificationfor using SQL over Access, so I kind of need it to work. :)Thanks in advance, maddman

Hello ,
I get this message in the error log file (ODS17809) for sqlserver 6.5 on windows NT 4.0
Although this parameter is set to 50 which is more than enought for our environment. When I look up in current activity, I see only 4 users connected.
IS there a way to find , why this message comes up and how many actula connections (alive or hanging) are with the Sql server.
Well, I can increase the number of connections, but that is not the solution , as I would like to track/debug where all the connections are being used up.
thanks in advance for your help/suggestions

Hi,
Environment:
I have a Sqlserver 6.5 production server used for web based applications
Compaq 5500 4 GIG RAM, 4 processor
Sql Memory config on that server is 1048576 (which is 2048 MB)
and the run value is 640000 (which is 1250 MB).
runvalue for user connections was 500
We have only 90 user connections may increase upto 100 depends on the connections. We don't have any overload on that server.
Error: I was seeing
"unable to connect maximum no. of 500 configured user connections are already connected" in the error log.
Action Taken:
I increased the user connections to 600
and rebooted the server. Immediately the same error I can see in the error log. But we have only 20 user connections at that time. I can able to connect.
Please advise me to get rid of this error.
Thanks,
Anu.
I have been reading through the article pointed to by the link below on msdn and its documented that one functional limitation of user instances is "Only local connections are allowed." I didn't understand the technical details(meaning) of that limitation and hopefully some one might explain it to me so that i can understand it better.

I am working with an application unde mssql 6.5 ,sp4. We have a separate
database for reporting on a different box. Each night we load a backup into
the database from the production database.
I set up a stored procedure to kill all users connected to this reporting
database just before the load.
THe job looks like this under scheduled tasks as a cmdexec:
isql -U sa -P -d master -Q"exec killusersall_sp 7" -o
F:MSSQLatchjobs
evdb.log
This job died with the following message:
Process Exit Code 1. ...[-b On error batch abort] [-O use Old ISQL
behavior disables the following]<EOF> batch processingAuto console width
scalingWide messagesdefault errorlevel is -1 vs 1 [-? show syntax summary
(this screen)]
The killusersall is paramaterize sp that I pass the dbid of the database
for whom I want all users killed. I need to put the stored procedure in the
master because I egt the spid from sysprocesses.
I do not understand why the job died. Does it matter if I named the stored
procedure as sp_killusersall instead of killusersall_sp which I used.
Can any one advise me about how to get the job to run? Any assistance will
be greatly appreciated. Thanks you.

Hi everyone!
Is it possible to control the number of simultaneous connections one login id can have?
I`d like to avoid my users to share their login ids and passwords to help them enter data into the system.
Thanks,
Mauricio
I can't find the answer...it just talk about the CPU / ram /database limit. thanks for you help!

I'm going to try to explain my situation.
I have a spid that I'm not able to kill, this were a select statement from with in access 97 application using a DNS connection.
So even that I reboot the client pc and kill the spid it still shows as active with status RollBack.
We have similar problem before and the only way that it disappear were re - starting Sql.
(system Sql 7.0 with sp1 and Access 97)
Thanks.
