It only takes a minute to sign up. I'm trying to execute a query that times out after 10 minutes. From experience I know that the query takes about 18 minutes to execute.
It's not ideal, and this is being worked on, however for now I just need it to execute. I get the message:. This is using SSMS on a remote computer. Why is the timeout setting not taking effect? Do I need to restart the server? This isn't possible right now. Configure the remote query timeout Server Configuration Option. The timeout is a client side setting and below explanation from Microsoft will clear the air why you are still having the issue.Gdi engine
Also this setting change does not require a restart. This value applies for an outgoing connection initiated by the database engine. The remote query timeout option specifies how long, in seconds, a remote operation can take before SQL Server times out.

This topic describes how to configure the remote query timeout server configuration option in SQL Server The remote query timeout option specifies how long, in seconds, a remote operation can take before SQL Server times out. The default value for this option iswhich allows a minute wait. This value applies to an outgoing connection initiated by the Database Engine as a remote query.
This value has no effect on queries received by the Database Engine. To disable the time-out, set the value to 0.
A query will wait until it completes. This will cause any other operations to time out after the specified number of seconds. For remote stored procedures, remote query timeout specifies the number of seconds that must elapse after sending a remote EXEC statement before the remote stored procedure times out.
Follow Up: After you configure the remote query timeout option. Under Remote server connectionsin the Remote query timeout box, type or select a value from 0 through 2, to set the maximum number seconds for SQL Server to wait before timing out. Copy and paste the following example into the query window and click Execute. Skip to main content.

SQL Server – Understanding Connection Timeouts and Query Timeouts
I've got a scenario when sometimes a user selects the right parameters and makes a query which takes several minutes or more to execute. I cannot prevent him to select such a combination of parameters it's quite legalso I'd like to set a timeout on the query. Note that I really want to stop the query execution itself and rollback any transactions, because otherwise it hogs up most of server resources.Valchromat 19mm
Add an impatient user who restarts the application and tries the combination again, and you've got a recipe for a disaster read: sql server DoS. As far as I know, apart from setting the command or connection timeouts in the client, there is no way to change timeouts on a query by query basis in the server.
And that will cause that your query takes less than 5 or fail. Then you should catch the exception and rollback if needed. In management studio you can set the timeout in seconds. However if you have a few queries i. This has to be solved on SQL server side, by the way of read-only replica, transaction log shipping to give you a read-only server to connect toreplication and such. Basically you give the DMZ sql server that heavy read can go to without killing stuff.
This is very common. That said, if you are at the liberty to change the code, you could guesstimate if the query is too heavy and you could either reject or return only X rows in your stored procedure. If you are mated to some reporting tool and such and can't control the SELECT it generates, you could point it to a view and then do the safety valve in the view.
Also, if up-to-the-minute freshness isn't critical and you could compromise on that, like monthly sales data, then compiling a physical table of complex joins by job to avoid complex joins might do the trick - that way everything would be sub-second per query. It entirely depends on what you are doing, but there is always a solution.Toroid air gap
Sometimes it takes extra coding to optimize it, sometimes it takes extra money to get you the secondary read-only DB, sometimes it needs time and attention in index tuning. So it entirely depends, but I'd start with "what can I compromise? You can specify the connection timeout within the SQL connection string, when you connect to the database, like so:.
I'm not quite sure that queries keep on running after the client connection has closed. Run a performance profile on the queries, prehaps some well-placed indexes could speed it up, or rewriting the query could too.
Update: According to this listSQL timeouts happen when waiting for attention acknowledgement from server:. Suppose you execute a command, then the command times out. When this happens the SqlClient driver sends a special 8 byte packet to the server called an attention packet.
This tells the server to stop executing the current command.Have you ever got into a situation wherein you feel you see something and work for a solution in a completely opposite direction?
Recently I was out of the country for a session and at the breakfast table I found a dark red bottle of ketchup which I used for my sandwich. Lesser did I know it was actually a spicy sauce. And on closer look this time, I found the mistake I did and how I ruined my whole breakfast.
These are times when you oversee something which looks like one and you land up as something completely different. During consultancy there are times when you are as an open book of all kinds of questions. When I was at a customer location, I was confronted by something simple. The developer walked up to me and said he had a question related to SQL Server.
Eager to hear, I asked the problem statement. He said he wanted to show me a code block. SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Now this is one of the generic error which you can ever get. I was trying to explain him how the errors and settings are when working with such error. I wanted to look at the time when the error comes. At this moment you need to understand the reason. Let us look at what the defaults are for our timeouts to put some context around this.
These numbers can be adjusted in different ways.
Either through code, or a connection string for example. Interestingly, with this rule of thumb and since he was using the default — I could guess he was getting Query Timeout in his code. I went on to talk how being on the latest and greatest would have easily solved him the problem.
He was not sure what I meant. Since he was on. NET 2. NET 4. We tried to get a stack dump too, as part of it. Now keeping the specifics apart, we got:. SqlException: Connection Timeout Expired.These jobs are handled from the operating system side by a Windows service that is responsible for executing these jobs and feeding the SQL Server systems tables with the metadata about these jobs.
The system database that is used by the SQL Server Agent for the job management called the msdb database. All information related to the job steps, schedules and the history can be found in the msdb database tables. There are three main database fixed roles in the msdb database that control the access to the SQL Server Agent. This role members have access on the local jobs and local job schedules that they owned only.
The members of this role can start and stop the execution of the local jobs, enable and disable it, and they have the ability to delete the jobs history for these local jobs. A system owner reported to me that her scheduled job failed last night even though the evidence indicates that it was completed successfully. To get to the bottom of this I went through the job steps, and I found out that the job contains remote query that is using linked server and it gave Query Timeout Expired error.
The result of the SQL server agent jobs can be checked by drilling down the job to View History as below:. The job history window will be displayed showing valuable information about the last few runs of the chosen scheduled job including Date, Server, Job Name, Result Message and the Duration in seconds:.
As shown in the snapshot above, the last run of our job succeeded. The step succeeded. SQL Server remote query is a query that contains outgoing connection to a remote database.
The default remote query timeout value is seconds. Setting the value to 0 will disable the timeout, so the query will wait until it is canceled. If there is a network latency between you server and the remote SQL server, you can change this value to resolve the query timeout issue from the Connections tab of the Server Properties dialog box below:.Shkendije mujaj
Our main concern here, how we could have an automated way to trace the query timeout message within the SQL Agent job steps result in our case, or any failure message in your case, in order to get a better indication of the job status.
To be initiative and to avoid future complains related to the same problem, it is better to automate this process and review it as a part of your daily check. Once the table is ready, we will modify our script to insert into that table, any query timeout message during the last day. It is better to schedule the below script as a SQL Agent job that will be run the first thing in the morning, to make sure that all the scheduled jobs are finished:.
What is required from your side now, is a simple select statement from that table, every morning, to make sure that no query timeout occurred last night on your scheduled jobs.When you use ODBC or SqlClient to access data from SQL Server, by default the query will be cancelled if there is no response from the server within a certain period of time 30 seconds by default.
ODBC or SqlClient will start a timer after sending the query to SQL Server and if there are no results from the server within 30 seconds, the query will be cancelled and a timeout error message will be sent to the application.
In case a network packet containing query results was received within the 30 seconds, and if we are expecting additional network packets additional rows that couldn't fit in the first network packetthen the timer is restarted, if the next network packet is not received within this 30 second period, the query will be cancelled.
The common reasons for SQL Command timeout are non-optimal schema or inefficient queries that execute for a long period of time or that miss indexes or lock wait issues.
It is important to tune the queries rather than increase the SQL Command timeout settings. In the video an example is demonstrated where decreasing the network packet size eliminates the timeout, this demonstration is to understand how network packets are involved in resetting the timer and to develop better understanding of timeout.
Changing the network packet size is not a solution to avoid timeout, tuning non-optimal schema or inefficient queries or adding indexes or avoiding lock waits are the proper solution. To identify the command that leads to SQL Command timeout error, you can use Extended Events and monitor event 'sqlserver.
The extended event script used in the video is available at www. By default, this is set to '0', which means no timeout.
And this will in-turn generate 'sqlserver. In the below video you can see an example of the SQL Command timeout. SQLTest Tool simulates the hands-on labs for you, no registration necessary.
