I'm not having much fun with connection pooling. The website I've written does dip into the SQL server all the time and quite a lot of times per page. Every time I nip into the SQL Server to get or set something I open a connection...
comGeneral.Connection.Open()
... do or get what I need and then close it. From what I've read any of the following should close the connection and return "one connection" (?) to the pool (top one, only if reading)....
... but that's not really working for me and I keep hitting the default max 100 open pools. So I've been doing all 3 of the above (again, top one, only if reading). But alas, still the stupid thing (Yes, I am aware I'm the stupid one) keeps hitting the max.
My new plan is to set pooling to false (pooling = false ?) across the entire website and take the performance hit which wont be terrible because I don't really do anything too demanding. Trouble is I don't know how, other than setting Pooling = False, but where exactly in the webconfig would this bit of code go?
Recently I bumped a problem with an asp.net application where seemingly random errors were thrown, although they were all related to the use of a connection object. Coming from Classic ASP, I wrote my pages by creating a connection object at the top of the page, and using that connection throughout the page. The connection object was opened whenever something had to be done with the database and closed immediately after.
Connectionstring: "Data Source=<server>;Initial Catalog=<catalog>;Integrated Security=false;user=<user>;password=<password>;Pooling=False;" So pooling=false.
My project use asp.net web form, and I code it with masterpage, page and mutil webcontrol to render a web page. A problem, request it slowly. I want to increase performace. I use webservice to request data, whole web control has code to request data from webservice.
I review code, and I think if my web used webservice pooling to render a webpage. But I haven't know how to code better, remove all webcontrol, and move their code to create a web page like asp web page (not asp.net)! using only one webservice to request data...
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'm currently experiencing and issue on whether to say a connection has been left open due to my code or if it's left open due to ADO.NET pooling. Here's a sample of my code:
Public Function ExecuteDataTable(ByVal strStoredProc As String, Optional ByVal objParams As SqlParameter() = Nothing, Optional ByVal cmdType As CommandType = CommandType.StoredProcedure) As DataTable Dim objDt As New DataTable Dim objAdapt As New SqlDataAdapter Dim objParam As SqlParameter Try OpenDb() If Not IsNothing(objParams) Then AddParams(objParams) End If objAdapt.SelectCommand = New SqlCommand With objAdapt.SelectCommand
[Code].....
Then when I go to open up the SQL Mgmt Studio, I look into the processes and the particular connection that has ran with the SQL that my function runs appears to remain open. So to me, it looks like ADO.NET is performing some kind of pooling. Is it safe to make that conclusion? How would I be able to tell if the connection is available to be used again by the ADO.NET pool?
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 have a dropdownlist which is connected to object data source for displaying data, now what I need is to connect to database using semicolon seperated list from web.config connection strings and then connect that to dropdownlist.
I have certain information in my webconfig such as the name of the database i am connecting to. However, I would like a situation where my aspx is able to obtain that information as well and display it in a label. Hence, how do I go about doing that.
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).
I have an ASP.net website running with the authentication mode on the web.config file is Windows. The webpages at the root do not need to have login & password form.
Now I created a subfolder called 'reports' and would like to implement a few web pages with the login & password authentication form.
Question, do I need to create another web.config file in the 'reports' folder and update the authentication mode="Forms"?
still, I do get the error that I have to provide at least one alphanumeric character.I do so and the error is still the same.why? is my regex wrong? I also took out the "confirm password" step. is that ok?
I have a website application which performs a function which I need to integrate into my main website application. Right now I'm getting errors as I copy and paste the parts of the web.config file from the working app into my main app. When I just paste in the assemblies, I get 2 errors. I'm just going to just paste both of them here and if you think you integrate them, I'd really appreciate it if you would paste it here in the thread.
[Code]....
And here is the one I'm trying to integrate into the one above:
