You can run both of these as much as you want and it shouldn't be a problem. The only side effect, is not in running the statements to perform the reconfiguration over and over.

But changing a value is changing the way SQL Server operates, and this could be a problem if you change to settings which are not good in your environment. Therefore, you should always test on another system before reconfiguring settings.

Also, it is wise to research each setting you intend to change and don't just try them, especially on a production system. Query wait is not a query timeout.

SQL Server does not time queries out, the connecting application in this case query analyser does. Query wait is how long an executing query waits for memory resources while executing.

The default is usually a good setting, don't fiddle with it unless you know what you are doing. If you have multiple queries waiting for memory then you have serious server problems that are not going to be fixed with a config change. I'm going to make a slightly different suggestion than the others. Messing around with timout settings means only one thing My recommendation is to find out what that code is and fix it.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:.

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.

Also you can have more advanced automated way to send you the content of that table by email. You can also modify the previous script to trace any type of misleading messages you may face by replacing the query timeout message in LIKE statement inside WHERE clause.

What I remember in the past whenever I set this option to any value, it will stop any query in SSMS after that many seconds. For example, if I am running a query which takes over 30 seconds and I set this setting as 5 seconds.

My all queries in SSMS will timeout after 5 seconds. This setting is there to avoid any such issues where users have run a query that runs a longer period of time or just stays blocked for a longer period of time. During the recent consulting engagementmy client and I tried to change the value in this setting and see its impact on the query but unfortunately, we noticed no impact of these settings on the query.

What threw me off is that I had to click outside the field areas in the blank spot of the query builder to show the properties of the entire query.

Otherwise you don't see the ODBC parameter. Thanks for the solution. Glad to help. BYW, I think the database querytimeout property only applies to queries created after the database property is set. Which makes sense. A global property should not override an individual object's property. You can also set the timeout to zero so it stays open as long as it needs to, but you could end up locking up your application if it fails to connect so be careful.
