DataSource Controls :: LINQ - Timeout Period Expired, Connection Pool?
May 19, 2010
I'm getting the following error after uploading my site on live server: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'm using the following code:
public static IQueryable<Property> Properties(string name, string city, string state, int pageIndex, int pageSize, ref int total)
{
ServerDataContext server = new ServerDataContext();
total = server.Properties.Count(x => x.Name.StartsWith(name) && x.City.StartsWith(city) && x.State.Contains(state));
return server.Properties.Where(x => x.Name.StartsWith(name) && x.City.StartsWith(city) && x.State.Contains(state)).Skip(pageIndex * pageSize - pageSize).Take(pageSize);
}
We have been getting this Oracle connection pool exception a lot recently for our ASP.NET website. This is the detailed exception message:
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.
This is our connection string
User ID=user1;password=password1;DATA SOURCE=Datasource1
how to set max pool size to 1 so that I can debug it on my local?
what is the recommended pool size for a website with 10,000 users?
am getting "Time Out Expired,The Timeout period elapsed prior to obtaining a connecttion from pool".Please suggest suddenly i am getting this error in 10% of the pages.

How to solve this error?
Where is the max pool size set and how to change it?
I am having a problem with my ASP.Net Web application. The application is developed using vb.net and is linked to a SQL Server database. Let me explain how the application works and the problem I am experiencing. The system is an online web app which allows registered users to create a CV online. One of the pages within the app gives users the chance to add a cover note to their CV. The page that allows them to do this consists of only a textarea control and a button control. The textarea allows users to input up to 4,000 characters.
Once the user clicks the 'Save' button to save their cover note info, the following code then executes.This code checks to see if the CV already has cover note info, if it does, then the application runs an update statement, otherwise, it runs an insert statement.The table within the database which records the cover note information is called tbl_covernote and has three columns, covernote_id (int and autoincrement), cv_id(int), covernote_text (nvarchar(max)).
The error which occurs sometimes is as follows:
Dim dr As SqlDataReader Dim param(0) As SqlParameter Finally [code]...
I have the problem of 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.
We are seeing the following timeout error being logged into our Event Viewer every now and then. We are using LINQ to connect to the SQL Server 2008 and the connection string is defined in the web.config file.One wierd thing I noticed is that the .NET framework is timing out trying to detect if this is SqlCe connection string. Why is it trying to waste time and then timing out when we have a SQL Server 2008 as the database? What can I do to fix this problem?
Server: Windows 2008 R2 64-Bit \IIS 7.5.7600.16385 Application Pool: Integrated Mode with 32-Bit Applications Enabled. Queue Length = 5000, Indentity = Network Service.Database Server: SQL Server 2008 [code]...
VS2010/C#. I have a gridview bound to a SQL Server table with the default SELECT statement returning only a few rows. This is straight out of the box, so no need to show markup.
Upon a button click event I update the datasource: SqlDataSource1.SelectCommand = hdnSQL.Value; Then bind: qlDataSource1.DataBind();
But when I run this, I get this error:
System.Data.SqlClient.SqlException was unhandled by user code. Message=Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I am clueless. I have done this many times in the past and NEVER encountered a timeout.
i have a web application that use a MySql DataBase. In a page, i have used the sqlDatasource control. The problem is that the conection with the database doesn't closed and i have a lot of open conections until show me the error that says me that the conection pool is full.
I want to use from two db connection in one linq query
My sample is:
int a=1; if(a==1) DataClasses1DataContext1 db = new DataClasses1DataContext1(); else DataClasses1DataContext2 db = new DataClasses1DataContext2(); var q = from c in db.F_Groups select c;
In this code a=1 so db connection is DataClasses1DataContext1
I want if a=2 then db connection = DataClasses1DataContext2
but this code is error.
db connections is completely same but in two deferent class a db connection is sql and another is oracle
I am using LINQ to SQL files in my class libray since every LINQ to SQL sources file is a seprate file and i have to set database connection string in each class library. Now, i have total 7 class libraires in my project how connection string be passed from web.onfg to LINQ file, so that i don't need to manually change the connection string. lke we did in asp.net 2.0 using connection string property in class file library.
How could we pass the same in LINQ's designer file.
VWD 2008 Express. IIS 6.0. Forms Authentication.My web site uses forms authentication (in case that makes a difference). Folks who are using the site indicate that it is timing out on them (logging them out) before they can finish some entries. How can I increase the timeout period? The following is my web.config file in my root directory:
[Code]....
Here is the web.config in the subdirectory to which all users are directed at login:
If I have not activity in browser for about 10 mins, shouldn't the Session object be removed. But after 10 mins I can still access the Session variable. Am I missing something here?
EDIT:
If I access a session variable after 10 mins as shown below shouldn't I get NULL
var myObj = Session["MyKey"] as MyClass; mObj is not NULL after 10 mins.
The problem is I have a stored procedure that runs consistently in Sql Server Management Server with a time of 2 seconds but when calling that same stored procedure from code it times out.
When it runs correctly from SSMS it should return about 30 rows.
I've tried a few different ways to call the procedure from code but every time the same result. This just recently started happening, yesterday it was working fine.
The preferred method for calling the procedure for us is using Linq2Sql which gives the following error message:
I'm using ASP.NET 3.5 (c#) with SQL Server 2008 server. Recently, I started getting error "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.".
After looking at forums for solutions, I added the below common code to my application.
[Code]....
However, intermittently, I'm still getting the timeout error. I added the logging to see where error is occuring. And found that before executing one of the query, it is giving this error. Now, my assumption is that I should have received this error after runnign query for 600 seconds (10 minutes) since I set it in the above function. But the timeout error is occuring instantaneously within 1 second itself. In the log, I printed one line above & after the query to identify how much time it would take. Surprisingly, the log says that 9:00 AM "Before query execution" & at 9:01 AM "timeout expired...."
I have a timer running in my web application. Each time the application starts up, the timer is created. The issue is that the app pool ends after an idle period which also ends the timer. The next request causes the app pool to start back up and a new timer is created.

I thought I had closed all the connections in my code:
