DataSource Controls :: Connection Pooling And Check Connection State?
Apr 7, 2010
In my DAL i have more than 100 methods/Function, each and every method am opening the sqlconnection and closing the connection, this is taking too much of time to establish the connection at every time. So what i expect is one common class will create the SqlConnection that will check if the connection is Broken or Closed then create the connection again else return the connection, how to do this(Also i would like to apply ConnectionPooling).

Some one can explain me the behaviour i am observing is correct..?
[Code]....
and here is the connection string:
<add name="SecurityDB" connectionString="Data Source=xyz,8000;Initial Catalog=abcd;User ID=abcd;Password=defg" providerName="System.Data.SqlClient"></add>
i expect it to fail at 101 iteration as the default max pool size is 100 and i am not releasing any connection after i open(ie., Not closing or Disposing). But the strange behaviour is i can go up to 230 iterations and then it gives me a timeout error, can not acquire new connection.
When i look in SQL Database for number of connections created it is only 100.
My question is : When connection is not released, how is it able to re-use the previously opened connection.

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.

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.

If I open a connection and don't close it after query execution completes, store it somewhere, and use it next time a request comes in, isn't it something similar to what .net does? Is it possible to maintain a pool of connections according to our requirements without depending on ADO.NET's internal mechanism? In case of ODBC, I read somewhere that connection pooling will have to be enabled from ODBC datasources and that it cannot be set from within .net. What if I open a few ODB connections, leave them open and
use those whenever a request comes in and close all of them when I know that I dont need them anymore. How is it different from connection pooling?

I am designing an ASP.NET (3.5) web application that connects to a Rocket Software UniVerse database.
I am shooting for a RESTful design and a MVC pattern. Rocket provides a .NET library called UniObjects.NET which handles everything for connecting and retrieving information from the database.
What would be the best way to in general to log my users into the database, then use that session via connection pooling? I see that in 3.5 there is the ASP.NET Routing Infrastructure and that looks promising am I in the right direction on this? Also does C# support decorators like Python and Java?

I am using microsoft enterprise libarary to connect to mysql using mysql .net connector (latest version 6.2.3)
But i am facing a problem of too many connections and connection pool reached maximum limit issue.
As connection is disposed by enterprise library iteself so i dont close the connection anywhere.
So after two or three hours i found i have 100 mysql connections in sleep mode which are doing nothing and are not being reused from the code .
So i want to ask is there any issue with my code or is there any issue with mysql connector

I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

I have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.

I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.
