SQL Server 2005 VS 2005 Web App - Connection Pooling
Dec 21, 2006
In a Web app as per above, where are connections to SQL Server and the connection pool monitored? Is it in SQL Server itself?
For example, in the following connection string:
"Server=(local); Database=TranOps; " +
"Integrated Security=SSPI;" +
"Pooling = true;" +
"Min Pool Size = 1;" +
"Max Pool Size = 5;" +
"Persist Security Info=False;";
The first user accesses a web form, and the connection is opened, and the pool started, then the connection is closed. I think at this point there should be five connections available.
When the second user accesses their web form, and connects using exactly the same string, it seems that if the connection is requested within a certain time frame of the first, one of the original five connections will be 'opened', or more correctly drawn from the pool, and used.
If I am understanding this correctly, then the pool must be maintained by SQL Server, not by anything in the web application. Is this a correct interpretation?
[Posting this in the security forum because in this forum I found a related post.]
I have a problem with SQL Server 2005 and application roles and pooling. I needed to use application roles and I needed to use pooling at the same time for an application. I am using sp_setapprole and sp_unsetapprole. In order to ensure that the application role is always set and unset by the application, I actually developed a custom Data Provider based on the SqlClient Data Provider. I have a custom Connection and Command class that wrap the SqlClient versions. Upon opening my custom Connection class, I execute the sp_setapprole stored procedure. Upon closing or disposing the connection, I call sp_unsetapprole.
This works fine in 99% of my tests. However, I have three or four methods (always the same ones, but one only fails ever so often) that fail, but only under the following circumstances:
Pooling is turned on (but pool size doesn't matter)
I am using my custom Data Provider (using System.Data.SqlClient does not cause this issue... but I am also not using approles then)
When other tests have run in the same test run. I.e. when I run the failing methods by themselves in a test run, there is no problem. So it seems to me that the problem is related to using application roles with pooling turned on. For scalability reasons, we cannot turn pooling off. When the methods fail, I see the following two (2) entries in the SQL Log:
Error: 18059, Severity: 20, State 1.
The connection has been dropped because the principal that opened it subsequently assumed a new security context, and then tried to reset the connection under its impersonated security context. This scenario is not supported. See "Impersonation Overview" in Books Online. I understand the error message somewhat. However, I am not sure why the "reset" of the connection occurs. My code does not call reset anywhere, so it must be something that happens in the background.
I am reviewing code to see if there is possibly a situation where the sp_unsetapprole procedure does not get called or does not get called successfully, but there is a lot of code (in many custom components).
I would like to know if anyone has a suggestion on how to solve this problem, or, find the code that may be causing the problem.
Hello, I have a question about Connection Pooling. I use the following Code on three defferent machines with the same result. No machine has any special configuration. OS is Win XP Pro Sql Server 2005. One Server has Windows 2003 Web Edition with Sql Express 2005. 1 for(int i=0; i<500;i++) { 3 SqlConnection con = new SqlConnection("Data Source=127.0.0.1\DB;Initial Catalog=Test;User Id=sa;Password=secret;Connection Lifetime=30;Pooling=true;"); 4 SqlCommand cmd = new SqlCommand("SELECT TOP 1 * FROM test", con); 5 con.Open(); 6 IDataReader reader = cmd.ExecuteReader(); 7 reader.Close(); 8 con.Close(); 9 con.Dispose(); 10 } 11 When monitoring The Counter logins/sec in Perfmon logins/sec getsup to 500 per second when i call this method (everytime!). MSDN says when logins/sec does not stay zero after initial call, pooling does not work. Can you tryy it on your machine an tell me what experience you make? Does Pooling really does not work?
I want to know what is min size ,max size,Connection Timeout and Connection Leak in connection pooling i have searched it on Google i found this below answer but still i have a confusion Please explain me in simple language with example"Setting an initial size other than zero can reduce the start time of the client applications because it ensures that a certain number of connections are always available. That could be an issue at around 09:00 in the morning when all users start their applications and connect to the server at the same time.
Setting the maximum size of the connection pool is usefull if you suspect that you have blocking problems due to the large number of concurrent queries. In this case you may be able to reduce blocking by limiting the maximum size of the connection pool. Of course, the pool already limits the number of concurrent connections, so you may never encounter this problem"
I would like to find out, what is the actual formula to set the right amount of connection pool size in a conn string. In my scenario, when 400 concurrent users are logged into the website, SQL Server starts timing out. I am thinking the following connection string should fix it, but I would appreciate if I can get some tips to optimize connection pooling. I really need to find out the criteria or the formula to set connection pool size in a connection string. I got the following conn string over the web, by just searching for optimized connection pools, but I am not sure if this will work. Also please explain max and min, and how what criteria do i use to set that size, I mean what does in the following example min pool size of 5 and max pool size of 60 means. Thanks.
conn.ConnectionString = "integrated security=SSPI;SERVER=YOUR_SERVER;DATABASE=YOUR_DB_NAME;Min Pool Size=5;Max Pool Size=60;Connect Timeout=2;"; // Notice Connection Timeout set to only two seconds!

I'm trying to connect to Desktop SQL Server 2000 from Windows mobile PC Emulator (VS 2005). I need a direct connection using connection string to SQL Server 2000 through local wireless network without IIS.
Bellow is the code that I use. After executing this code I get an error on line Conn.Open(). Error says SQL Server does not exist or access denied. SQL is un and running, and I can log in using SA username from the desktop. Even if I chance IP for another SQL server in my connection string I still get the same error. There is no firewall of any kind running.
Dim connectionSTR As String = "Persist Security Info=False;Integrated Security=False;Server=192.168.0.202,1433;initial catalog=MyDB;user id=sa;password=;"
Dim Conn As SqlConnection
Conn = New SqlConnection(connectionSTR)
Conn.Open()
If Conn.State = ConnectionState.Open Then MessageBox.Show("Open") End If
About my environment: SQL Server 2000 is running on Desktop PC with Windows XP SP2. Application which I need to connect to SQL Server is in Visual Studio 2005. I execute the application in Windows Mobile PC Emulator and try to connect to SQL Server from emulator.
Hello, How are you? I have a problem when I try to create a new connection with Microsoft SQL Server 2005 Compact Edition from Visual Studio 2005 IDE. When I€™m going to choose the data source, the SQL Server 2005 Compact Edition provider doesn€™t appear in the list. I installed the SQL Server 2005 Compact Edition from this page http://www.microsoft.com/downloads/details.aspx?FamilyId=%2085E0C3CE-3FA1-453A-8CE9-AF6CA20946C3&displaylang=en. In the additional information says by installing SQLServerCE31-EN.msi installs the provider (System.Data.SqlServerCe.dll) in the GAC (global assembly cache) and registers the OLEDB provider (sqlceoledb30.dll). So, I don€™t understand why couldn€™t I create a new connection with Microsoft SQL Server 2005 Compact Edition from Visual Studio 2005 IDE?
Hey I need to know what shall i specify in this connection string in visual studio web.confug file inorder to connect to ma registered server (locally) not directly to my dedicated server ....cuz i am facing network connection problems .... b4 i used to use this connection string : <add key="conn" value="data source=IP addresseel,1433;initial catalog=xxx;user id=username on the dedicated server;Password=password on the dedicated server;timeout=60"></add> So how can i change it ???? to be able to connect locally ???? Please Help ???! Thanks in advance Hiba
I downloaded SQL Server 2005 Express and some sample databases (incl. Adventureworks_data.mdf), but when I try to Add Connection in VS 2005 to point to this db and use the Test Connection button, it gives the error:
--------------------------- Microsoft Visual Studio --------------------------- An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) ---------------------------
I've tried setting the data source as either "Microsoft SQL Server Database File" or "Microsoft SQL Server", but get the same error.
Any tips on verifying SQL Srv Express is installed correctly? Any ideas on how to solve this problem?
Hi! I have this problem: When I try to open database table under database explorer in VWD 2005 EE, it says that it failed to attempt connection due to user instance and the connection will be closed.
When I try to right click on my database's file name under database explorer and click connection to set the connection setting and click on "Test Connection", it says the same thing.
This happen sometime, but after I restart my computer, I am able to access my database file again.
All -- Please help. I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005. Note that I do not want to use the "Attach a database file" type of connection string. Note that I am using the site http://www.ConnectionStrings.com as a reference. Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS... (A) What exactly does the error in Item 4 mean? (B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string? (C) Are there any alternatives? (D) What do you suggest?
Problem: ColA (Source) Rounding error to PARTY_NO (Destination) I have a field of text of in a flat file that the flat file connection manager Source picks up correctly €œ70000893€? However when it gets the OLE DB Connection Destination the data has changed to 70000896. That€™s before its even Written to the database. The only clue that something is wrong in the middle is the great Data viewer shows the number as 7.000009E+07 Other clues looking at the data it appears there is a rounding error on only the number that dont end in 00 ColA (Source) PARTY_NO (Destination) 71167300 71167296 70329000 70329000 70410000 70410000 Any ideas people? Thanks in advance Dave
Hi, I had an old web application created during asp.net 1.1 and it have a connection problem with the sql server 2005 when it is mirgrated to a new webserver with dotnet framework 2.0 platform. I have enabled the remote access(TCP/IP and named pipes) in sql server 2005, did all the neccessary things, check whether the TCP/IP is enabled, named pipe is enabled... I created another web application using VS 2005. The database connection works perfectly well.This are the connectionString from the old web application.<appSettings> <add key="ConnectionString" value="Server=127.0.0.1;Database=somedb;User id=user; Password=somepassword; Trusted_Connection=False; POOLING=FALSE"/></appSettings> Thankyou in advance!
I see the connection showing up and in the next second it is gone.
The connectionstring i have is
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;pooling=true;Min Pool Size=2;Max Pool Size=50;Connection Lifetime=120;Initial Catalog=test;Data Source=TESTMACHINESQLEXPRESS;
And then in the log, the log grows almost every second 3 entiries !! "Login succeeded for user 'TESTMACHINEUser'. Connection: trusted...." "Login succeeded for user 'TESTMACHINEUser'. Connection: trusted...." "Login succeeded for user 'TESTMACHINEUser'. Connection: trusted...."
So the problem is that pooling does not seem to work. I dont see any connections being held for more than 1 second
I am looking for some guidelines for SQL Server connection pooling. I would like to know the number of recomended connections for a SQL server based upon number of CPU's and or memory and I want to monitor or check the connection pooling? I would also like to know any guidelines around SQL server connection pooling.
Hi,I'm using ASP 3.0 and ADO with a web based MS SQLServer 2000 database.Webpage forms collect criteria for SQL queries (dynamic SQL?). These are mostlySelect queries to return inventory lists. Inventory details are posted bymeans of Insert Update and Delete queries. All connections use the sameconnection string. A new connection is opened each time the data is accessedand closed and set to null/nothing afterwards. If site traffic becomes highwill connection pooling be handled automaticaly (by MTS)?Many thanksRay Allison
I have created an instance of sqlconnection and using transaction i am executing 5 insert statements (Database - SQL Server 2005). I have the finally block where i call the dispose method of the transaction and close method of the connection object.I often get the below mentioned error:
Exception Type: System.InvalidOperationException
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.
Hi I have a Community Server Forum in my site with a 2500 hit per day and I confused with Connection Pooling. Is it necessary for my site to use Connection Pooling? If it€™s necessary, what is the best value for following items in order to maximize performance?
Pooling Connection Reset Enlist Max Pool Size Min Pool Size Connection Lifetime Thank you very much.
Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

If I have two ASP.NET applications installed on the same machine, and both are using the same connection string to access SQL Server 2005. Are they share the same pool or use separated pools? I need to be sure that how many connections would be connected to my database server. For example, the max. connection pool size is 100, if both Web app share the same pool, then there're may be maximum 100 connections to database. It they use separated pools, then connections may grow to 200.
I've got a function that returns a connection to a DataReader:static public SqlDataReader GetDR(string sql, string connString) { SqlConnection myConn = new SqlConnection(connString); SqlCommand cmd = new SqlCommand(sql, myConn); SqlDataReader dr;
myConn.Open(); dr = cmd.ExecuteReader();
return dr; }I call it like so:SqlDataReader dr = PAS.GetSqlDataReader.GetDR(sql, connString);And I'm always careful to close the connection when I'm done using it via dr.Close(). Except I just started noticing that when I run my app andstart doing a fair amount of work around it - I very quickly get a timeout that I've run out of connections. D'oh! I've triple checked my code andverified that I always remember to close my connections. It's there - every single time!So I'm obviously missing something. Should I not be using a function like GetDR since it doesn't close the connection within the function?
Hi, I'm trying to optimize an ASP.NET 2.0 app where, with a load of 100 users, the CPU usage on the web server is a reasonable <20% but the db server (SQL Server 2005) often goes up to 100% and never below 20%. When viewing the Performance Monitor counter SQL Server :General Statistics/User Connections this shows that there are 50-65 connections. When the number of connections go up the db server's CPU usage also goes up along with web page response times.When viewing the Sql server Activity Monitor it, for all connections, always says that the Login Time and the Last Batch are the same. This has got me wondering if no connections are pooled and that all connections always are closed and reopened and that would explain why the db server is so jammed.Could someone give me some pointers as what to check to find optimization points. Regards,Mathias
There's always been a lot of confusion about what prevents connection pooling -- when I was learning .Net 1.0, I was told that any differences in connection strings -- even cosmetic ones -- would prevent pooling (or, more accuratlely, that they could only share connections with identically formatted connections). For example, conn string1 =
Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;
I have a web application. In this app i have one class genral for database transections. I create new object of this class on every page in page load event & dispose it on UnLoad event. After sometime this app gives connection pooling exception.
Means connection are not closed, but i disposed the object like
I was asking in one Technical Test, the question is not exactly like, but i want post the outline of that(because i don't remember the exact one)
Suppose u have connection with Sql Server database, and let say some 30 users are already connected (through some aspx page), if one more new request is coming, is it created new path or it will reallocate or destroy existing connection poll and assign??
Can anybody tell me?
if possible please post some of Basic and Adavanced questions regarding Sql Server (with aspx)
I am using VB5 SP3 and ADO 2.5 to connect to SQL Server 7 SP2 and I'm trying to test connection pooling.
I open three ADO Connection objects as follows:
Set con = New Connection con.Open "Provider=SQLOLEDB;Data Source=(local);Initial Catalog=pubs;User ID=sa;Password=;OLE DB Services=-1"
The second and third connections open virtually instantly, which seems to indicate that pooling is working, however, when I list processes in SQL Server it shows one process for each separate ADO connection. I thought the whole point of pooling was to make all these ADO connections map to the one physical connection and therefore one process. What is going on?
Just to make sure, I also tried it with RDO 2.0 and ODBC connection pooling and I get exactly the same results.
I'm very worried about this because it could result in our using up twenty or so SQL Server connection licences per workstation instead of one.
Hello:How does one pool a connection object? I have the same application runningon 4 different machines, all connecting to the same server/SQL Server 2000instance for DB activity.Some posts have mentioned pooling the connection objects to reduce overhead,but how do I do that for the 4 separate computers.Appreciate any response.Regards,Ryan Kennedy
Hi,Is there a way to control the connection pools using SQL Server 2000? Iknow how to alter the connection string to dothis(http://msdn.microsoft.com/library/d...ry/en-us/cpguide/html/cpconconnectionpoolingforsqlservernetdataprovider. asp), but I amlooking for a setting in SQL Server that allows me ultimate control over allconnections to the DB. eg: I'd like all connection pools to timeout after5min of inactivity, set the maximum pool size, etc. I am assuming that thereis some part of the GUI that allows this, or maybe even some (ugh) registryediting! ;-)Thanks,Lance
We have an large SQL database being accessed by a C# application. Each hit on the database opens a connection then closes it when done. We are currently experiencing errors when more than 20 users access the database at one time. One of the things I am wondering is if we are using connection pooling. From BOL I am lead to believe connection pooling is off by default. Can I turn on connection pooling as a default in SQL Server or do I pass 'pooling=true' as a parameter on each connection string?
I use IIS 6.0 with php and the authentication method is the €œintegration windows authentication€?
I have a problem i d€™ like to use odbc connections pooling to access my database, however the authenticated user must be member of the administrator group to use this feature.
I tried without success to activate ODBC connection pooling for an ASP (classic) application running on Windows Server 2003. I used the ODBC administration applet and created the registry value described in "INFO: How to Enable Connection Pooling in an ODBC Application".
What are the steps to correctly activate ODBC connection pooling with IIS 6?
