Is there a way to Set Connection timeout used in IIS in asp.net programaticaly in one page ? without setting it globally for all the website from IIS itself ?
Update your connection string.
Add Connection Timeout=900 in your connection string.
Connection Timeout always specified in seconds and Default is 30 seconds.
You can set these according to your need.
Your connection string may look like:
server=servername;database=DBName;User ID=UserID;Password=PWD; Connect Timeout=timeinseconds
Hope its helpful.
Create a second cpnnection string in your web config with out timeout and in the page you want, add timeout you want.

I'm struggling with setting connect timeout with c# HttpClient or its siblings (HttpClientHandler,WebRequestHandler,...) . There's a timeout property in HttpClient, but it seems to be a timeout from the beginning of the request until receiving the response. I want to have a method which specify that for example if you don't received ACK from the net socket within 10 seconds for example , then break up and do the next.
I saw that there may be something similar in WinHttpHandler class, but it seems to be deleted or not available in recent version. compare the first link vs second :
1.WinHttpHandler MSDN
2.WinHttpHandler Microsoft Docs
I really need this, because I must differentiate asap between IP's which have a working web servers (maybe slow) vs which don't have a web server at all.
I use HttpWebRequest.Timeout in my project to verdict the connection time before establish tcp connection. And use HttpWebRequest.ReadOrWriteTimeout to verdict whole response timeout.
Ps: The HttpClient seems cut off some useful properties.
Recently,I have to develop a system which will fetch huge data from SQL Server 2008 R2. And then need to create HL7 messages using these data and send these HL7 messages to another application. I need to fetch data and create HL7 messages within looping also. The problem I am facing is that connection time out when 1 or 2 minutes after running the application.How can I prevent this problem? What should I do?
Modifying the connection string in the web.config , you could append ;Connection Timeout=30. The timeout value set in the Connection Timeout property is a time expressed in seconds.
Please Refer Connection Time out
setting the timeout value to 0, you are specifying that your attempt to connect waits an infinite time. As described in the documentation, this is something that you shouldn't set in your connection string.
A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect waits indefinitely.
I would like to check my internet connection while using WebClient in order to download a file. (WebClient.DownloadFile()).
I want to check if the connection still available in the middle of the downloading process.
How do I do that ? (in C#)
Thanks a lot.
You cannot generally detect that the internet is available or not. But heuristically, you can start a second thread which tries to GET google.com with a read timeout of 5s every 15s or so. That way your connection check can have different, harder timeouts than your main download.
You can't. There is no way in TCP to check the status of a connection other than by trying to use it. Set a read timeout, and respond accordingly to the resulting SocketTimeoutException; and respond to any other IOException by closing the connection and maybe retrying, depending on your specific requirements.
How can I limit timeout for connecting to Oracle Database? I use devart dotConnect Express Edition on data access layer. I tried add Connection timeout=30; to connection string but it doesn't give right result (even a little weird, first time it really limits to 30 seconds, but not on all connection attempts). Then I find out that
Connection Timeout Time (in seconds) to wait while trying to establish
a connection before terminating the attempt and generating an error. A
value of 0 indicates no limit. The default value is 15 seconds.
Available in Direct mode only.
from Devart site
I can't use direct mode because I use Express Edition. Then I tried to set this parameters in TNSNAMES.ORA
DB1 =
(DESCRIPTION =
(CONNECT_TIMEOUT=11)
(TRANSPORT_CONNECT_TIMEOUT=10)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.100.8)(PORT = 1521)
)
)
(CONNECT_DATA =
(SERVICE_NAME = DB1)
)
)
Still works incorrect. OK, going down and try yo set connection timeout in SQLNET.ORA
SQLNET.INBOUND_CONNECT_TIMEOUT = 5
Another one fail! Does anyone know how can I set timeout restricting allowing time to connect to DB1? It now finishes connection (connection fails) for approximately 20 seconds.
I've never used Devart's dotConnect library, but looking at the OracleConnection class it seems that you should be able to close the connection after a certain period of time by calling OracleConnection.Close(). This should take you out of the blocking state while you're trying to Open the connection.
This is not exactly like setting the timeout, but it may work. Furthermore, check the ConnectionTimeout property when you're debugging this code in order to confirm that the timeout is properly set.
OracleConnection.ConnectionTimeout works in Direct mode only. It is ignored when connection is established via Oracle client, which manages connection in this case.
My ASP.NET website while trying to connect to the database for first time after a period of inactivity throws an time out exception.
I understand the connections in the connection pool get terminated after some idle time for some reason (Firewall or Oracle settings) and the pool or app doesn't have a clue about it.
Is there any way to validate the connection beforehand so that the first try doesn't throw an exception?
I don't have much control over the DB or Firewall settings. So I have to deal with this is my application.(would prefer if there is any web.config settings)
I am using: ASP.NET 2.0. Oracle server 11g, Microsoft Enterprise Library DAAB to do all my DB operations.
I did some search on this topic but didnt find any solid solution for this yet :(
There is a State property on SqlConnection that you could check
if(myConnection.State == ConnectionState.Open)
{
// perform your query
}
You can always increase the Connection Timeout property
