Configuration :: Website Db Selects Runs Extremly Slow On Windows 2003 (IIS6) When No Console User Is Logged In?
May 23, 2010
I have a really weird problem that I've been investigating for at least one week now. I deliver a website hosting both ASP classic and .NET 3.5 content in IIS6 on a Windows 2003 server environment with MySQL db backend. The solution has been installed on several servers (some hosted in WMWare) with no problems. On one specific server, also hosted in WMWare, the user experience great performance issues on the website. The problems are most seen when using database resources and is not limited to either .net or asp classic, but I am still not sure that the problem is only related to database calls.
Following components are involved:
IIS6 .NET FW 3.5 MyODBC 3.51 / 5.1 MySQL 4.x
Code executed on the server using all resources above runs smoothly when the IIS is not involved. The website shows times up to 2 minutes to execute code that takes 2 seconds outside the IIS. The exact same code is executed. Using profiling tools, I've seen that the great loss comes within calls to unmanaged code, for example when System.Data.ODBC namespace to calls into myodbc.dll.
The tricky part is: If at least one console user is logged in to the server, the performace problems are not seen anymore. When the user logs out, the problem appears again.I have tried to reinstall all components above, tried different versions of MyODBC, tried different website authentication methods, tried to run website under administrator privilegies, installed various MS KB's with no success.
Environment.WorkingSet incorrectly reports the memory usage for a web site that runs on Windows 2003 Server.(OS Vers: Microsoft Windows NT 5.2.3790 Service Pack 2, .NET Vers: 2.0.50727.3607)
It reports memory as Working Set(Physical Mem.): 1952 MB (2047468061).
Same web site runs locally on Windows Vista with a Working Set(Physical Mem.): 49 MB (51924992).
I have limited access to the server and support is so limited.
so i have computed the total memory by traversing with VirtualQuery.
Total of pages with state: MEM_FREE is 1300 MB.
(I guess server have 4 GBs of RAM and PAE is not enabled, max user mode virtual address is 0x7fff0000.)
So, i know working set is not only about virtual memory. But, is it normal to have such a high working set while its very low on another machine?
I'm running windows 7, so I installed on my machine the oracle client version 11.1.0.7.0 (ODP.NET - Oracle.DataAccess version 2.111.7.20) . I'm trying to deploy an asp.net web application to a server that is running windows 2003, which has the oracle client version 11.1.0.6.0 (ODP.NET - Oracle.DataAccess Version 2.111.6.20)
Now when I compile my application and deploy it in a setup project (as pre-compiled). The start page of my web app tires to connect to Oracle and it returns the following error message:
"Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified."
Which is super weird because, cause the web.config file as shown above has Version=2.111.6.20.
Now the strange part is that if I copy the source code from the client to the server, the same code, same config file, it works just fine.
So I'm thinking that the pre-compiled version is telling the server to load Oracle.DataAccess Version=2.111.7.20, maybe in one of the dlls, not in the config file for sure.
Has anyone run into this problem?
what's the best approach to deploy to servers with different oracle client version? (I have a similar problem trying to deploy to a 64 bit machine)
I have developed a website in ASP.NET and deployed on IIS 6.0 server on windows Server 2003.I used asp.net 2.0,SQL server 2005,AJAX and javascript .It is working.The problem I have that this website is slow. How did I deployed website on IIS? I went to Build-->Publish Web Site and it then created a folder with all pages, I simply copied that folder on webserver and put path in IIS. Is that a correct way to deploy aps.net webite or not? let me know is any other best way to deploy website that can make my website faster.
when I deploy a website in IIS Windows Server 2003 R2 . First time deploy, it seemed no problem at all (fyi, the one who deploy for the first time is not me, but my friend) but after one or two days this problem occur. I can't browse from IIS and Internet Explorer. In Internet Explorer the page display:
"Internet Explorer cannot display the website." The worse, no error log data ever produced in Application category in Event Viewer.
I've tried change the address from localhost to 127.0.0.1 but the response is still the same. I even tried access just localhost alone. It should display the default homepage from IIS but the response is still the same too. I've checked IIS' Web Service Extension, the Active Server Pages and ASP.NET 2.0 are set to allowed. I also have tried make a virtual directory with just index.html inside and the response is still the same.
FYI: The server seems run in 64 bit (HP Proliant server). The website I build only used ASP.NET Ajax 1.0 and Crystal Report for VS 2005. From the server, I can access the internet but not the localhost.

I have built my site using VS.Net 2010 on my XP machine. I would like to deploy it to my server which is a Windows 2003 Server. I have tried to do it with FTP, but it keeps failing with the error that "Front Page Extensions are not installed on the web server". When I check the server the extensions were installed and I also checked IIS and the service for the extension is allowed.
We have multiple websites deployed onto Windows 2003 WebServer running under .NET Framework 2.0 SP1 version and now we want to upgrade it to .NET Framework 2.0 SP2, so just wanted to check that after upgrading the .NET Framework on the server do we also need to re-deploy the websites by recompiling them in .NET Framwork 2.0 SP2 version or it's not necessary as they will automatically start referencing the latest assemblies?
I need to deploy an asp.net 4 website on a windows server 2003 remote server. I have updated the server's .net framework to 4.0 and installed IIS 7. how to deploy the website because I have no idea how to.
I have an ASP.NET site that uses impersonation. As the impersonated user I use a domain user (not a local machine user). The site is hosted in IIS 6 running on Windows 2003. In IIS 6 for directory security windows authentication is ticked.The site has been running now for about 6 months without any problem. However since about a week back the site has started spuring up really wierd errors. For one, users cannot access the site anymore. When accessing a windows authentication dialog box appears having the user to enter the credentials. However these credentials are not accepted and the standard unauthorized page is displayed
I want to deploy asp.net 4.0 web site on windows server 2003, Now I already have a classic asp site running on it. Would there be any problem if I install .net 4.0 framework for my new site. Will the existing site (the one in classic asp) be affected?
Can someone point me to a step-by-step guide on how to deploy ASP.Net applications to a totally empty and brand new Windows 2003 Server?The server has ASP.Net and the .Net framework installed on it. IIS is up and running. I have created a new application pool.
I have an application which is used by others on different server without problems. The app was programmed by a programmer who is not available now. It was developed on .net 2.0. The windows 2003 is a new server, asp.net is enabled. from iis, I can configure it to use asp.net 2.0....,
but, when I load the site, it always show the 404. even after I change the default.aspx to a blank page, it still shows 404. however, if I put a default.htm in the folder, and it can be loaded without problems.
what can cause this? how to fix it? if I installed a vs2005 express on the server, will it fix the problem?
it seems the asp.net 2.0 dll is not recognized on server. never had this problem before.
I have been trying really hard to activate and launch a COM object using an ASP.NET web application. The aspx website has a code-behind file that has a reference to this COM object (which is an actual application -a CAD software). When required, the VB code creates (or launches) the application.
The complete set-up works in a Win-XP (32-bit) environment both under debugging using visual studio and when the website is accessed by an outside user (through IIS server in XP). But the same application doesn't get activated when it is hosted onto the Win-2003 (32-bit) IIS server. I get "Object reference not set to an instance of an object" error.
The way I have setup in Win-XP was to grant ASP user and Internet guest user permissions to the COM object in the DCOM Config and since the windows firewall is enabled, I add the exe file (associated with the COM object) to the exception list. For the case of Win-2003 server, I add the Network Service permission to the COM object. But the setup doesn't seem to work at all. I am not sure what I am missing and how to get the application to launch.
I have the same issue, I have added the On before the Application start, or Session Start and it is still not working.Application_OnStart or Application_Start is not firingSession_OnStart or Session_Start is not firing..Note that in my development environment it is firing (both of the names).When I am adding the Global.asax file, there is only one file (no .cs file). And when I am publishing the project, I am not getting the Global.asax file, I am getting a xxxxGlobal.asax.dll file on my bin folder...
