I want to be able to create methods to do stuff like opening the connection to the database.Right now if I want to do that I have to put all the code to open the connection with the database in every class.What I did is create a new class called methods, this class is in the App_code folder.I have researched but don't understand how methods are created and how to call them. If someone can give me an example regarding a database connection method, I might be able to really understand how a method works. Basically, this is the code I have to use everytime I want to open a connection to the database:
string connectionString = ConfigurationManager.ConnectionStrings["dbConn"].ConnectionString;
I have developed a web service using ADO.Net entity framework3.5 and LINQTOSQL3.5.
Now i want to increase the connection timeout? How should i ?
can I increase this by modifying the connection string in the web.config

We're trying to get connection pooling working with uodotnet and currently failing miserably. When we turn connection pooling off everything works as expected, but when we turn it on we often get timeouts or errors with one of the following trace outputs:
2011-03-28T15:09:28 System.Exception: Non-negative number required.
[Code]....
Not all the requests fail (for example, when run through a load testing tool, 7/20 requests failed with the timeout problem).
It seems that the sessions are remaining in the pool and new attempts to create a session are repeating until the timeout limit is reached (30 seconds). We're using uodotnet.dll version 2.1.1.7196 and UniVerse version 10.3. running on an HP-UX server. We've got a single license on the dev machine we're testing on with 10 connections available in the pool (theoretically!). We're writing an ASP.Net web site, and we create a new session in the Page_Load() event which is passed to all UniVerse routines and then call close on the session in Page_Unload()/Page_Error().
to what we're doing wrong? We expected that connection pooling would improve performance, falling back on the standard mechanism if the pool was full, but whereas the non-pooled version works fine with 20 simultaneous requests, the pooled version regularly fails. We've set the connection pooling on in the application's web.config, setting MinPoolSize to 1 and MaxPoolSize to 10, leaving everything else at the defaults.
I need to set connection timeout in oledb connection string like
stringA= "Provider=SQLOLEDB.1;Persist Security Info=False;User
ID=sa;PWD=password;Initial Catalog=DB;Data Source=127.0.0.1;Connect
Timeout=30" [code]....
I am developing logging application with asp.net & vb.net & OracleAt present I'm using this mechanism to write logs

What is the difference between connection timeout and command timeout?
In our application sometimes it is showing a timeout error. When we increased the command timeout value to 100(from default 30), its working. Is there any issue in increasing the command timeout value.
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?
Alright, we have two database servers, one is owned by us, one owned by a partner. Our partners have been having issues lately that have been causing us numerous sql timeout errors, which takes down our whole system. We'd prefer to limit the time those queries can take to say 20 seconds max, otherwise quit trying and throw the error (which we can catch with a try/catch block). Couple of questions: Is there a way to set a particular db/connection string to timeout after X seconds? Is this the best way to quarantine that other system? or are there better ways to go about this?

I am opening and closing SqlConnection properly.
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);
}
I am getting this error:
"timeout expired. the timeout period elapsed prior to obtaining a connection from the pool"
when I am testing my webiste on production server. Its working perfectly on my local machine but not on production.
Sometimes it works and sometimes not.
We have the timeout value set to 120 in our <form> tag within the web.config. We do not have a session timeout set.. and we have various connection strings.
We are having a problem where a session variable will disappear (become NULL) .. but, the form evidently remains 'open'.. or no re-login is required..... so, my question(s):
1. what is the relationship between form timeout and session timeout
2. how do I set session timeout
Hopefully I am posting this in the correct forum.
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 an ASP.Net application that makes an AJAX request to retrieve at report. The report can run for a long time so I set the asyncpostbacktimeout in <asp:ScriptManager /> to 600. However, when I try to run the report, if it runs for longer than 90 seconds it fails to come back. I can see in the IIS logs that the POST request succeeded with a 200 status and I can see the time taken is much less than 600.
The web page dutifully waits for the entire 600 seconds before returning with a timeout error:
Error:
Sys.WebForms.PageRequestManagerTimeoutException:
The server request timed out.
Is there any setting I should be checking in IIS? Connection timeout is 900 seconds.
I'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
The session state timeout is set using this web.config element
<sessionState mode="InProc" cookieless="false" timeout="120" />
The forms auth is configured using this web.config element
<system.web>
<authentication mode="Forms">
<forms loginUrl="Login.aspx"
protection="All"
timeout="30"
name=".ASPXAUTH"
path="/"
requireSSL="false"
slidingExpiration="true"
defaultUrl="default.aspx"
cookieless="UseDeviceProfile"
enableCrossAppRedirects="false" />
</authentication>
</system.web>
What is the difference between the timeouts specified in each of these elements? If both are different, how would it work?
I have a page of each every click has ajax call to my server (hence, the ASP extends the session)
I have ASP.NET session set to Xmin. I want when X+1 min expires, I have expiration page. what I did was to set the JS timer to validate every x+1min to see if the session expired (the problem is that the JS and the ASP session timeouts are not synced)

I have an issue to where my users are logged into my system but thier session is null so when they try to do something in the system after 20 minutes, i get null reference expceptions because my session is gon
What is the best practice for handleing the session, should i kick the users out before thier session ends and when they log back in thier session will return or atleast a new one will be created right? How should I handle this?
I wanna write a method to get or set session timeout at run time.
View 1 RepliesI'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.
