System.Data.SqlClient.SqlException: Timeout Expired.

Jul 21, 2007

Hi there,



I am not sure it is the right forum. The Exception is thrown in C# app while saving a few databases. Small databases are being saved OK but this one has 12,934,142KB after the last backup. I am not even sure what the words "last backup" mean in this case. It is possible that is the size of the database from two months ago when first the problem appeared. Since then I've neglected backup being preoccupied with other problems although the database grew.



The backup is executed by this store procedure:

USE [hist_OHLC]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER OFF
GO

ALTER PROCEDURE [dbo].[backUphist_OHLC]
AS
BEGIN
SET NOCOUNT ON;
ALTER DATABASE hist_OHLC SET RECOVERY FULL
BACKUP DATABASE hist_OHLC TO DISK = 'L:SQLServerBackupshist_OHLChist_OHLCFullRM.bak'
BACKUP LOG hist_OHLC TO DISK = 'L:SQLServerBackupshist_OHLChist_OHLCFullRM.log';
END


What can I do about it? What is the rational way of backing up databases of this size?



What is the rational way of maintaining databases of this size in SQLEXPRESS? Shall I perhaps break this database down into fragments?



The tables contain daily records, about 500 per day. I can conceivably create another database every month or so but it will be a hassle.



How can I increase the timeout?



I just repeated the backup. All databases have been saved except this last one--Imoved that backup operation down the chain to be the last one. One database with about 1.5GBytes was saved fine.



I checked the timeout it is 15 sec. One has not control over it in C#. It does not have a Set option.



15

MyHandler caught : Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

The backup or restore was aborted.



Thanks.

System.Data.SqlClient.SqlException: Timeout Expired.

Dec 3, 2007

We have some big problems with our SQL Server 2000 database right now.
The code has not been changed for over halv an year and some days ago we started to get this error.





System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Both web and database server is running fine.
Any help is appreciated!

(We are now pretty sure that all errors occurs when we are doing inserts to the database.)

System.Data.SqlClient.SqlException: Timeout Expired

Sep 26, 2007

Hello, we have a fairly large .NET application that uses MSSQL Server 2005 Express.

I am getting the following error loggged to our error log somewhat often:

System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

IIS and MSSQL server are on the same box, and talk locally. The server box is NOT losing internet so that is not the problem.

What could be causing this? Is this because we don't have enough system resources on the server, meaning CPU, RAM? Or is it poorly written ASP.NET or missing configuration information in the web.config file?

Thanks for the insight.

System.Data.SqlClient.SqlException - When Inserting Image

Jul 13, 2006

Hi All,
I have a form (asp website with the default.aspx and default.aspx.cs) which I use to connect to the SQL Server 2005 database and insert, update,get and delete data to and from it. In the table I have a column called Picture to insert a photo (usually bmp files) which I declared as a varbinary(max). ID is the primary key and is an int (i tried it to be numeric & varchar).
I am trying to insert data into the table using a form with this syntax:
SqlConnection enter_conn = new SqlConnection("user id=;" +
"password=;server=servername;" +
"Trusted_Connection=yes;" +
"database=Member Profiles; " +
"connection timeout=30");
enter_conn.Open();
string insertSql = "Insert dbo.Details(ID,Last_Name,First_Name,Middle_Initial,Project, Organization,Manager,Current_Skills,Biography,Hobbies, Picture) Select 1001, 'ABC','XYZ','R',' Website Development','ACT',LKM','ASP.Net, C#.Net, SQL Server 2005, SharePoint, Java, ',' developing the new website for ACT using SharePoint and SQL Server 2005', ' Singing, Listening to Music, Dancing, Cooking, Swimming', BulkColumn from Openrowset( Bulk 'C:\photos\rose.bmp', Single_Blob) as Picture";


SqlCommand myCommand = new SqlCommand(insertSql, enter_conn);
int i = myCommand.ExecuteNonQuery();
 
 I have no data in the table and am doing the first insert. Though the data gets inserted I am getting this exception:
System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'PK_Details'. Cannot insert duplicate key in object 'dbo.Details'. The statement has been terminated. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery() at _Default.Enter_Click(Object sender, EventArgs e) in c:Documents and SettingskrkondaXMy DocumentsVisual Studio 2005WebSitesMember ProfilesDefault.aspx.cs:line 82

Oct 29, 2007

 Im trying to insert some values into a table but i get the following error:
System.Data.SqlClient.SqlException: Must declare the scalar variable "@username".
the strange thing is that the variable username is declared at the beginning and acording to my debugger the variable username has a value (that it gets from a textbox when a button is pressed). Here is my code so please feel free to point out what im doing wrong. Im a beginner to using asp.net.1 protected void ButtonSubmit_Click(object sender, EventArgs e)
2 {
3 string @username = TextBoxUsername.Text;
4 string @company = TextBoxCompany.Text;
5 string @password = TextBoxPassword.Text;
6 string @mail = TextBoxMail.Text;
7 string @adr = TextBoxAdr.Text;
8 string @phone = TextBoxPhone.Text;

System.Data.SqlClient.SqlException: Login Failed For User 'ext_access'

May 2, 2008

I am having a very strange and frustrating problem with moving an application from Development to Production.
I have been working on this application on XP with VS2005 with SQL Express on my local machine.  Throughout the development lifecycle I have moved it to the Server multiple times to test things and everything has been working fine until this last time.
What I have done since the last time:
Added some ASP.NET AJAX functionality
Added some views that I am having to fill a dataset from the dataset to manipulate the data before presentation.
Everything has worked fine without any issues on my local machine with my local database.
I just made backups of the databases and restored them on the server and have moved all my project files up to the server.  I then installed the ASP.NET AJAX Extensions 1.0 on my 2.0 server.
 
NOW - The Problem:
The entire site works fine, I can read data from every table of every database, and I can also write data to all the databases.  However, this one page has a GridView that I pull data from the database and fill a DataSet with the data.  I then manipulate the data, adding some data from other databases and then present it to the browser.
This is working fine on my local machine, but since pushing this to the server I get an error:
System.Data.SqlClient.SqlException: Login failed for user 'ext_access'
Line 36:         ad.Fill(ds, "CaskInfo")Line 37:         Dim Table As DataTable = ds.Tables("CaskInfo")Line 38:         Table.Columns.Add("Company", GetType(String))
I have checked the database and the SQL Server and the user listed above has the correct access to the database, which I would guess since everthing else is working fine. I use the same connection information throughout the app and it is stored in the web.config so I am certain nothing is wrong with my connection information.  I access that information with the same code throughout the application as well so I know it is correct.
I know this may not be the most trimmed piece of SQL code, but I figured I would post it incase there is something inefficient in my SQL that could be causing this.
Here is my code leading up to the error.
Dim conn As SqlConnection = CreateConnection2()Dim connectionString As String = conn.ConnectionString
Dim myConnection As New SqlConnection(connectionString)Dim ad As New SqlDataAdapter("Select CaskID, CompanyID, SiteID, UnitIDVCC, UnitIDTSC, DATEPART(mm,DateLoaded)as Month, DATEPART(dd,DateLoaded)as Day, DATEPART(yyyy,DateLoaded)as Year, COCName, AmendmentName, HeatLoad, Dose, DryTime, Damaged, Debris FROM CaskInfo, COCInfo, AmendmentInfo WHERE CaskInfo.COC = COCInfo.COCID AND CaskInfo.Amendment = AmendmentInfo.AmendmentID", myConnection)
Dim ds As New DataSet()
ad.Fill(ds, "CaskInfo")
 
 
Using this connection code:Function CreateConnection2() As SqlConnection
Dim conn2 As SqlConnection = New SqlConnectionconn2.ConnectionString = ConfigurationManager.ConnectionStrings("MainWeb").ConnectionString
conn2.Open()Return conn2
End Function
And this is the line in the web.config:
<add name="MainWeb" connectionString="Data Source=N2K3APPS;Initial Catalog=NUTUGData;Integrated Security=false;Pooling=False;User Id=ext_access;password=zzzzzzz" providerName=".NET Framework Data Provider for SQL Server"/>
Thanks!

System.Data.SqlClient.SqlException: Login Failed For User 'NT AUTHORITYANONYMOUS LOG

Apr 2, 2004

I have searched all the forums on this issue and tried the other options but nothing seems to work. I have an IIS server using asp.net to connect to a SQL database on a separate server which also happens to be a domain controller(i.e. no local accounts). I have tried changing the connection string, web.config, etc. but I still can't get connected. I believe the issue is with the SQL security but I'm not sure.

IIs is set up for Integrated Windows Auth.

Here is the web.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<!-- application specific settings -->
<appSettings>
<add key="connectionString" value="Data Source=VGISQL2;Initial Catalog=PaymentApplication;Integrated Security=SSPI;" />
</appSettings>


<system.web>

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging. Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->
<compilation
defaultLanguage="c#"
debug="true"
/>

<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.

"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.
-->
<customErrors
mode="Off"
/>

<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"

"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<authentication mode="Windows" />

<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous
(unauthenticated) users.
-->

<authorization>
<allow users="*" /> <!-- Allow all users -->
<!-- <allow users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
-->
</authorization>

<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the
trace information will be displayed at the bottom of each page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from your web application
root.
-->
<trace
enabled="true"
requestLimit="10"
pageOutput="false"
traceMode="SortByTime"
localOnly="false"
/>

<!-- SESSION STATE SETTINGS
By default ASP.NET uses cookies to identify which requests belong to a particular session.
If cookies are not available, a session can be tracked by adding a session identifier to the URL.
To disable cookies, set sessionState cookieless="true".
-->
<sessionState

stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"

<!-- GLOBALIZATION
This section sets the globalization settings of the application.

System.Data.SqlClient.SqlException: SQL Server Does Not Exist Or Access Denied.

Jan 8, 2007

Hi all

Please help me.

I have an asp.net 1.1 (vb.net) application which accesses data from a sql server 2000. I published this application on http://test.autenmas.co.za and the database I access is on 196.23.156.196. I am getting this error message when I run the application from this site:

System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.

But it's working fine on my local, development machine. I am using the following connection string in my connections:

"Data source=196.23.56.193; Initial Catalog=Autenmas; User Id=xxxx; password=yyyy"

Is there anything wrong with my code, is there anything that must be done on the web/database server or any other configurations for that matter, what really is the problem??????

Thanks in advance.

System.Data.SqlClient.SqlException: Error Converting Data Type Numeric To Decimal.

Aug 31, 2004

Hi There,

I'm using C# to get a value for a DOUBLE precision variable, called "Length", from a textBox using the following line:

Length = Convert.ToDouble( txtLength.Text )

I'm also using the following lines to prepare my stored procedure call:

arParms[9] = new SqlParameter("@Length", SqlDbType.Decimal, 5);
arParms[9].Value = record.Length;

My stored procedure has the following parameter definition:

@Length decimal(9,3)

My problem is that if someone types a value bigger than 999999 in the textbox he will get for sure the following error:

System.Data.SqlClient.SqlException: Error converting data type numeric to decimal.

I don't know how to either make sql or C# to truncate the value or catch the exception to automatically assign 0 to the parameter.

Please Help.
Moshe
