I am gettting SQL time out error in my .net service.
As the service is already installed on the production, is there any way I can increase the timeout for the service from App.Config file.
At present, I am getting this exception after one minute, I have to make it to around 10 hours because the stored procedure we are using takes 2-2 hours to execute.
You could try setting the CommandTimeout property on your SqlCommand. I hope you are not doing this in an ASP.NET application.
You can set the timeout in your connection string with "connect Timeout = 100000000;" or whatever you want your timeout to be
The time out setting is up to database server.
In SQL Server Manager open the SQL Server Properties and pick the connection tab and set time out as big as You need.
Ps.
zero goes for no timeout.

We have started a new project in .NET Core. We are just starting out and we are hitting a Web API endpoint to get some reference data of 8 records.
We noticed in our Angular screen that perodically (about every 10 requests) to a screen that the EF query takes about 6 to 15 seconds to run, rather than the 30ms it normally takes.
On debugging we know that we are getting right up to the .ToListAsync() and then in SQL profiler we can see it initiates the query and it take a delayed time.
So first impressions says its a SQL issue but if we run the SQL query manually in SQL itself it never delays.
Any ideas?
This might have to do with the connection pooling setup of efcore, It should not request a new connection on each request to db, enable connection pooling by adding this in your dependency management:
builder.Services.AddPooledDbContextFactory<DbContext>(
o => o.UseSqlServer(builder.Configuration.GetConnectionString("AppContext")));

I'm having some troubles with timeouts on my website. It has a rather large newsletter receiverlist (approx. 100k recievers). We deliver a tool for sending out newsletters, and based on the query for the newsletter (segmentation fx), we make show a total number for recievers of the newsletter.
If I run the query through SQL Server Management Studio I get a result in roughly 2 seconds. But if the querye is run through a client browser I get the same timeout evert time: "[Microsoft][ODBC SQL Server Driver]Query timeout expired".
I have tried adjusting the Server.ScriptTimeout parameter but with no luck. It seems as there's a problem with the data connection, but that's where I get stuck.
I'm hoping some of you brilliant people know the answer to this one :-)
Thanks!
Have you tried setting the Connection Timeout property of the connection string?
-- EDIT --
PS: I know I've given you a VB.NET page, but the connection strings will be pretty similar.
I have an extremely simple BizTalk orchestration that takes a HIPAA 837 file in, breaks it into its individual claims, and saves the complete xml message to the database. I have a WCF SQL send port that calls a stored procedure to do this... the proc just does an insert with no return value. The problem is that I keep (randomly) getting the timeout error:
Details:"Microsoft.ServiceModel.Channels.Common.InvalidUriException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
I just tried this with a small file - only 5 individual claims in it (so I should only need 5 connections from the pool, right?). The BT server has been doing nothing else for the past 10 hours (no messages processed). Yet I still received this error... My MaxConnectionPoolSize is set to 100, so that means 100 connections have been held open and idle for at least 10 hours ?? What's going on here?
Thanks.
I would take a look here or here. To be honest the WCF SQL adapter is very picky and quirky as to what SQL it works well with and what it doesn't. I typically look for a custom solution for inserting into SQL to have more control over the inserts or updates without having to write my SQL specific for the SQL adapter. I find if I'm inserting or updating more than one table or returning a complex records, I avoid the WCF SQL adapter.
If that's not an option, look at re-writing your SQL.
I am using a script task in ssis 2005 which takes some time and getting a problems timing out with "The operation has timed out". Where abouts is the setting to change the timeout period? I cant seem to find it in the properties in task and I do not wish to make a global change to timeout.
Probably the problems with timeout is in the databases. You should define a new timeout in the connection managers you have in your SSIS package
I am using SQL Express 2008 as a backend for a web application, the problem is the web application is used during business hours so sometimes during lunch or break time when there is no users logged in for a 20 minute period SQL express will kick into idle mode and free its cache.
I am aware of this because it logs something like:
Server resumed execution after being idle 9709 seconds
or
Starting up database 'xxxxxxx'
in the event log
I would like to avoid this idle behavior. Is there anyway to configure SQL express to stop idling or at least widen the time window to longer than 20mins? Or is my only option to write a service that polls the db every 15mins to keep it spooled up ?
After reading articles like this it doesn't look to promising but maybe there is a hack or registry setting someone knows about.
That behavior is not configurable.
You do have to implement a method to poll the database every so often. Also, like the article you linked to said, set the AUTO CLOSE property to false.
Just a short SQL query like this every few minutes will prevent SQLserver from going idle:
SELECT TOP 0 NULL
FROM [master].[dbo].[MSreplication_options]
GO
Write a thread that does a simple query every few minutes. Start the thread in your global.asax Application_Start and you should be done!
Here is a good explanation: https://blogs.msdn.microsoft.com/sqlexpress/2008/02/22/understanding-sql-express-behavior-idle-time-resource-usage-auto_close-and-user-instances/
Whatever: I do not know the time after sql express goes idle. I suggest to run the script below every 10 minutes (maybe task scheduler).
This will prevent SQL Server Express from going idle:
SELECT TOP 0 NULL FROM [master].[dbo].[MSreplication_options] GO
Also make sure all data bases' property is set to AUTO_CLOSE = FALSE
