Connection Pool To Access Sql Server For Multiple User?
Dec 12, 2007
HI,
I am using SqlServer2005 as data base for my web application. I am able to connect to the database through DBCP connection pool . Its working fine for 2 user. When ever 2 users do transaction, it works fine. But 3 users do the transaction, its trowning error.Even i increase the pool size the behavior is same.
error:
com.microsoft.sqlserver.jdbc.SQLServerException: Server failed to resume the transaction, desc: 3f00000002.
For a change I wrote a connection pool to access the DB. I am getting the same error. i.e. Its working fine for 2 user and throws error for more than 2 users.
Is there any setting to be made?
Same application is working fine for Oracle10g.

This is my code...
public partial class test : System.Web.UI.Page
{protected void Page_Load(object sender, EventArgs e)
{SqlDatabase database = (SqlDatabase)DatabaseFactory.CreateDatabase("ConnectionString");DbCommand command = database.GetSqlStringCommand("SELECT UserName FROM Users WHERE UserID = '6264'");
using (IDataReader reader = database.ExecuteReader(command))
{if (reader.Read())
{lblTest.Text = "test";
}
}
}
}
This is my error:

Hi guys!
I have a dev server that has about 15-25 connections which is fine.
**
Looking at performance counters: _global_
under SqlClient: Current # connection pools
under SqlClient: Current # pooled connections
under SqlClient: Current # pooled and nonpooled connections
**
BUT when I look at staging and production I have only 4 or so...
WHAT'S GOING ON?!?! The querystring doesn't specify the max pool
size, pooling, nor timeout values. So I'm guessing it uses the
defaults. ( I also tried putting in max pool size, but it didn't
change anything! )
Does anyone know how I can increase the value? It is impacting the performance of the site considerably. Thank you!

Hi
I have seen the threads already in here about connections and SQL Server but I too am having a connection pool problem.
I am explicitly making a connection, creating a command object, executing a datareader then closing the command and then disposing the connection. The connection just prior to the dispose is definately closed.
However when I do an sp_who in SQL Server the connection is still listed. I have a connection timeout of 30 seconds, so I am considering reducing this to 5 seconds but dont wish to. So therefore when a process is called repeatedly instead of using an existing connection in the pool, it thinks that this connection is still active and therefore creates a new connection. Because all of this is in an ascx, I cant code for one connection to stay open for all 30 instances of the control.
This is a problem because I am creating controls at run time and using page.databind and at that point, I exceed the connection pool and therefore the site crashes out to the "SQL Server Timeout" error.
Anyone else seen this?

Hello.
I have a db dal containing the following code:
SqlCommand cmd = new SqlCommand();
cmd.Connection = dbc;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "SOME STORED PROCEDURE";
.
.
.
declare some SqlParameters
.
.
.
dbc.Open();
cmd.ExecuteNonQuery();
dbc.Close();
This code, when concurrently running via several threads, yields the following exception:
"The connection was not closed. The connection's current state is open."
My questions are:
1. Why don't .Net allocate another connection from the pool (I try to only concurrently run 2 threads while there are 25 connections in the connection pool) ?
2. How can one explicitly allocate a connection?
3. How do you suggest to solve this problem without a mutex/monitor etc' on the 3 bold lines above and without BeginExequteNonQuery()?
Thank you !

Hi,
I just developed a ASP.NET website with SQL Server 2005 as database. I am having connection crash problem when multiple user click on same link to fetch data from the database. If users click on different links or there is few seconds of time gap between the data access, then it works fine. But the connections crash problem only occurs when 2 or more users click same link at same time.
I am using the following kind of Datalayers to access the data from database:
public static ContentInformation GetContentForUpdate(int ContentId)
{
ContentInformation result = new ContentInformation(); ;
SqlCommand command = new SqlCommand();
command.CommandType = CommandType.StoredProcedure;
command.Connection = Connection;
command.CommandText = "Content_GetContentForUpdate1";
SqlParameter parameter = new SqlParameter("@ContentId", SqlDbType.Int);
parameter.Direction = ParameterDirection.Input;
parameter.Value = ContentId;
command.Parameters.Add(parameter);
try
{
command.Connection.Open();
SqlDataReader reader = command.ExecuteReader(CommandBehavior.SingleRow);
if (reader.Read())
{
// read the data
}
reader.Close();
}
catch (SqlException ex)
{
Trace.TraceError(ex.Message);
throw ex;
}
finally
{
command.Connection.Close();
}
return result;
}
I would be really grateful if someone can help me out with this problem. Waiting for the soonest reply. Thanks.

client: ado.net 2.0 SqlClient, xp sp 2
server: sql server 2005, win 2k
I have a stored proc eg spProcA which does not start a transaction
If I call this proc from ado.net code without any transaction around it affecting the isolation level, the isolation level within the proc call is read committed, as expected
If I then call the same proc within a System.Transacstion.TransactionScope with a different isolation level eg Serializable, then i get the expected isolation level in the proc.
However, if i retry the proc without any transaction around it, the isolation level is now the same as the TransactionScope, (eg Serializable), and this persists until either the connection pool clears down (either because it becomes dormant or via an explicit ClearAllPools.
I can resolve this problem by setting the isolation level in every proc (or call to every proc), but i wondered if i am missing something more straight forward?

I build an asp.net 2.0 (VS 2005) web application and put it on the server. The installed SQL server is SQL server 2003. I get this error message when i keep the application running for 10 or 15 mins. "Timeout expired. The timeout period elapsed prior obtaining a connection from the pool. This may have occure because all pooled connections were in use and max pool size was reached."
I made the server timeout unlimited but the error keeps coming up after some time of openning the application. The application session time out redirects the user to the login page and doesn't throw an error like the one i mentioned above.
Any idea. Thanks in advance.

From what I understand, some database drivers provide automatic database pooling, in the sense that when an application closes a connection, it is not dropped until after a certain timeout. If the same, or another application, request a connection then the "pooled" one is returned.
What's the situation with C#, .NET Compact Edition and SQLce? Is it a performance hit to open and close a connection, or is some kind of automatic pooling in effect?
Thanks.

Hi All,I'm having a bit of a problem with a c# program which creates and index file/table. The number of records I need to process is around 3500, the main loop. Each of thoes records I need to look at a 2 text fields and create an entry in an index table for each valid word found in thoes fields. I call a stored proc to save the key word. So this stored proc get called numerous time per record.What seems to be happening is proceese about 400 main rcords the errors out with the following error 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." }Has anyone had a similar problem? if so any suggestions on how to fix, I've been looking at this problem and recoding for the last 4 days! I need some help! Using SQL Server 2000 & .net v1.1Thanks in advance Davej

I'm opening a large number of connections to a SQL server 2005 database using a SQL object based on the System.Data.SqlClient library. When I log out of the application, I call the ClearSQLConnectionPool method of the SQL object and this should clear the pool of these connections. This has worked in the past, but lately I have noticed some odd and very annoying behaviour.Very often I log out of the application and few, if any of the connections disappear. Just this morning I opened the application, logged out and all but one of the connections disappeared. Then I opened it again, logged out and none of the connections had gone. If I open the application again all of the past connections are still there plus the new ones.I know it works, its just very inconsistent. The problem may be with IIS, SQL or with library; I just can't tell which.Any ideas?Many thanks

Dear GroupSorry for posting this here. I'm desperate for a solution to thisproblem and thought some of you might have come across it with .NETand SQL Server.Let's assume I've the following code:Private Sub Button4_Click(ByVal sender As System.Object, ByVal e AsSystem.EventArgs) Handles Button4.ClickDim sqlConnection As New System.Data.SqlClient.SqlConnectionsqlConnection.ConnectionString = "workstation id=THEINTREPIDFOX;packetsize=4096;user id=sa;data source=""(local)"";p" & _"ersist security info=False;initial catalog=TestDB"sqlConnection.Open()sqlConnection.Close()sqlConnection = NothingEnd SubWhen I click 100 times on the button the page finally times out with:Timeout expired. The timeout period elapsed prior to obtaining aconnection from the pool. This may have occurred because all pooledconnections were in use and max pool size was reached.Of course I could increase the max pool size but this isn't thesolution to this problem. I wonder what's wrong with my code?According to MSDN, if the connection is closed it's released back intothe pool. Also tried to dispose but nothing helps. It looks like thatit keeps connections and doesn't release them. I'm grateful for anyhints, ideas, suggestions on this problem as I'm very desperate tosolve this.Thanks very much for your time & efforts!Martin

I created a database that will be distributed to my customers. This database is running on an Instance of SQL Server 2005 Express edition. I removed the admin logins from my SQL Server Instance so in theory, only my application connecting itself using the Sql Server autenthication will be able to be access the data (using "sa" having a password that I set at the installation).
For now, all this is working fine and after some tests, I haven't been able to access the data in any ways except by using the "sa" and the password my app is the only one to know.
But the problem is coming from a security leak when using User Instance. Indeed, I've been able to create a program getting the content from my MDF file. If somebody try to get connected using User Instance on his own SQL Server instance, he will be able to reach the data.
How could I prevent this to happend? Is there a property or something that could be set into the database that would prevent the database (mdf file) to be used with User Instance?
Thanks!

Hi,
I have recently installed SP2 for SQLServer 2005 and started to have connection pool issues. I have tried to explicitly mention the pool settings in connection string and yet pooling doesn't seem to work. I have one more box with no service packs applied and is pooling is perfect!. Has any one experienced this??

I was wondering if someone could help explaining how the SQL Server handles all incoming connections, I and a friend started a discussion about using the connection pool in ADO.NET or not in a specific case.
Usually when creating like an ASP.NET Page it's recommended to use the connection pool, because it optimizes the performance, by using already created connection, so we don't have to recreate the connection all the time. I have always thought that the connection in the connection pool had an open connection on the server. So 5 connections in the connection pool, would be 5 open connections at the server. But after having the discussion with my friend I am not so sure anymore.
Say that I would create a client application (.NET using ADO.NET) that connects to the database and work with that data. If I then have 1.000 clients and each client have a connection pool with 5 connections in it (I think that the default numbers for the connection pool), then there would be like 5.000 open connections on the SQL Server, where most of the connections actually never do anything more than hanging around and waiting... And then the connectionpool is not 1 per client but 1 per connectionstring.
So if my client scenario would access data from 2 different databases, there would actually be 10.000 open connections at the SQL Server. So now I think that there must be a server connection pool or something to handle the connection from the clients. So that there would only be like 10-50 open connections at the server for the 1.000 Clients that was connected.
How is it? Is there 1 open connection in the server for every connection in the connection pool? If that's the case, it would be better for the SQL Server if I don't not use the connection pool in the client, but instead open the connection when we need it, and then close it, and taking that little performance hit every time, to help the performance on the SQL Server.
Best regards
- Magnus

Halo all
I have a problem with "timeout expired. Thei timeout periode elapsed prior to obtaining a connection from the pool. This may have occured because all pooled connections were use and max pool size was reached"
Then i explore and found out that i did not close my SqlDataReader, SqlDataAdapter, SqlCommand or my connection.
But i have a function that return a SqlDataReader.
Is this function will cause a connection problem?
Thanks in advance
Public Function GetDataReader(ByVal strSQL As String, ByVal DBCon As DB.DBConnection) As SqlDataReader Dim MyCommand As SqlCommand = New SqlCommand(strSQL, DBCon.GetConnection())
If DBCon.GetConnection().State = ConnectionState.Closed Then DBCon.GetConnection().Open() End If
Dim dr As SqlDataReader = MyCommand.ExecuteReader()
Return dr

Hi
Last week I was receiving an error when trying to connect to two of our seven sql servers from my laptop via my domain admin account. The only fix was to have my laptop rebuilt and everything re-installed.
Today however another administrator is starting to have the same problem but to only one of the seven servers!
When that administrator uses my laptop with her domain admin account it works!?
What could possibly be going wrong with our laptops? We have not installed or changed anything.
The full error message we see:
Login failed for user ''. The user is not associated with a trusted SQL Server connection. (Microsoft Sql Server, Error: 18452)
The error being logged on the server: (two errors are logged each time)
SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 53.35.165.148]

Hi to all,
I am using a connection string like
data source=RemoteHostName;initial catalog=myDb;password=sa;user id=sa;
Max pool size = 200;
And now strange thing is happening ,, I am receiving error :
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
The SqlServer Activity Manager is telling that only 100 connections are pooled, and I guess that the Max pool size is 100, It is not being changed by my Connection string. As I am trying to change the default 100 pool size value to 200.
Huh , So stucked up , how to increase the Max pool size.. Is there any way .
I am getting worrried.
Any help ??
Thx and Regards

I would like to know if there is a way to find out who changed a users roles/access WITHOUT using the audit function. For example, if a user account was created and given SA access then changed to read only, how can I find out who made that change? I tried searching for an answer, but kept getting no results. I'm thinking this may tie into the sys.sysusers view?

Hi,
I have a copy of VS2005 and i have installed the Microsoft SQL Server Developer Edition
I am trying to do my first connection using ASP.net (yay for me...) and it has failed...with this error..Login failed for user 'testuser'. The user is not associated with a trusted SQL Server connection.
can someone please point out why? yes i know that the error seems pretty straight forward but how do i fix it? like how do i make the user a trusted server connection? where do i do it? and what are the steps? the user is an administrator and by rights should have all access to everything....
connection string
SqlConnection MySQLConnection; MySQLConnection = new SqlConnection("server=cmptrname\databsename;uid=testuser;password=password;database=mytest");
btw while your reading do you have any examples of opening a db with the connection string in the web.config file? because i get some error "connection string has not been initialised" using the
system.Configuration.ConfigurationManager.AppSettings.Get
i though i would stick to the top code first before i tackled the web config error first....
Thanks heaps

Hi all,
I am new in asp.net. In my web.config file, I wrote the connection strings as below and then I got the above error. I already changed SQL server Authentication mode to "SQL server and Windows". Any idea? Thanks in advance.
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=xxx;Initial Catalog=mydb;User ID=test;Password=test;Persist Security Info=False;"
providerName="System.Data.SqlClient" />
</connectionStrings>
