Oracle Data Provider Pegs IIS Worker Process When Web Site Is Stopped?

May 6, 2010

We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following:

1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite - we use IIS, not the ASP.NET dev server, for all of our sites). This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool.2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question).Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.

How To Recognize Whether The Process Is The IIS Worker Process From Within A .NET Code

Dec 25, 2010

Dear ladies and sirs.

I have a .NET infra code running both within the IIS worker process and within a desktop client app. How can the .NET code determine whether it is running within an IIS worker process?

I know that I could check the name of the process (w3wp.exe, for instance), but I would like a more robust approach. I wish to make a side note. This is not a production need. I need this information to enable certain scenarios useful during the development and testing phase. Specifically to ease the testing of secure vs non secure configurations.

Ofcourse this is extremly annoying as I don't get any syntax formatting for the project or intellisense.

Way To Attach To The Worker Process In VS

Jun 2, 2010

I'm using VS 2010. And in VS 2010 it's even more painful now to attach to the worker process when you want to test your local IIS site via IIS, not the VS built-in web server.It's more painful because now when you select the worker process () via the Debug Menu | Attach to Process | w3wp.exe it brings up an additional prompt asking if you're sure you want to do this.

AJAX Call Not Starting IIS Worker Process

Dec 21, 2010

First of all, I'm not a pro on IIS configuration topic.With that being said, I got a website written in VB.NET 3.5 Web Forms. I have a small web service, ASMX, running as a part of this website. One page on the website calls the web service with AJAX (jQuery $.ajax function, post). The server is running Windows 2003 and IIS 6.0. The website and the web service are sharing the same Application Pool.

What is the difference between IIS Worker process, Application pool and application domain? Do we have more than one application domains in one application pool?Does one application domain means one virtual directory?
If we have 2 virtual directories pointing to same physical folder. Will they share the same memory or different when there instances are opened in the browser? Will they be in 2 different application domains?

Configuration :: Worker Process Recycle, Every 60 Seconds?

Jul 13, 2010

We recently had to enable Memory Recycling on a 2.0 app pool (IIS6). We checked both boxes, leaving in the default values of 500 MB for virtual memory and 192 MB for used memory. Here's where it gets interesting. Every 60 seconds, on the dot, the worker process is forced to recycle.Our tests were spamming the site with concurrent users trying to get the virtual memory up to 500MB, but we never could (as viewed in task manager). However, that didn't matter. We tested it by simply recycling the pool and hitting one page, once, and seeing around 30MB allocated and then just waiting 60 seconds and watching the process die in task manager (and a new one start up).We've increased the value for maximum virtual memory to 768MB and the issue *appears* to have gone away, but just arbitrarily accepting a fix isn't how we like to do things. I haven't found any officially reported bugs, kb articles, or solutions on blogs that point to what is causing this. To me, this means either it's some crazy environmental issue or the answer is really obvious and we just can't see it.

Transaction When App Pool Recycles Or The Worker Process Is Terminated Forcefully

Apr 13, 2010

The architecture of the application is straight forward. There is a web application which maintain account holder data. This data is processed and the status of account holders is updated based on number of business rules. This process is initiated using a button on the page and is a long running process (say 15 mins). A component is developed to do this data processing which internally calls stored procedures. Most of the business rules are kept in stored procedure.

WCF / ASMX :: Recycling AppPools Without Interrupting Active Worker Process?

Oct 25, 2010

we're hosting a webservice that runs with up to 9 worker processes in it's application pool. There's a memory limit configured for the application pool to keep the system/server performant. Now my concern is that, if the memory limit is reached, a worker process may be recycled although there is an active request handled by this worker process that needs to be responded/finished first. The problem is especially with purchase/order requests, as such requests typically run several minutes and must not be aborted by any worker process recycle process. Is there any configuration setting that allows me app pool recycling by granting that no active process will be abandoned?

State Management :: Trigger Worker Process After A Server Reboot?

Jan 3, 2011

Does anybody know how I can trigger the ASPNET_Worker process on Windows 2000 and 2003 servers? Apparently, every time we reboot our servers on Saturday nights our monitoring software generates alerts for the ASPNET_Worker process and they don't go away until during the morning hours. This leaves me to believe that this process doesn't automatically run after a reboot and only starts to kick in when clients access our websites during the day. I'd like to be able to trigger the process after a server reboot so our monitoring software doesn't identify it as down.I was reading this post on http://weblogs.asp.net/jgalloway/archive/2006/06/01/Avoid-IISRESET-in-ASP.NET-applications-_2800_added-bonus_3A00_-ASPRESET_2900_.aspx and I believe the code on that article is what I need. However, I am only a SysAdmin and have very little knowledge about programming. The writer mentioned compiling the code using SnippetCompiler but after downloading the software I can't seem to figure out how to turn the code into an .exe.

Visual Studio :: The Agent Process Was Stopped While The Test Was Running?

Oct 11, 2010

I have a solution that was originally created using VS 2008. I have quite a few unit tests that all passed when ran in VS 2008.

Yesterday I opened this solution in VS 2010 and converted it using the wizard. The solution built just fine, it runs just fine, BUT now all tests that access the db fail. I get the same error on every test (below).

"The runtime has encountered a fatal error. The address of the error was at 0x5b3b5ad7, on thread 0x19a4. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack."

In test classes that use ClassInitialize() and ClassCleanup() methods, all the tests fail. All tests fail with the same error, "The agent process was stopped while the test was running." Tests in test classes that do not utilize ClassInitialize() and ClassCleanup() (these tests do not hit the database) all pass.

When this was a VS2008 project all 153 tests passed. No changes have been made to these tests, other than converting the project to a VS2010 project.

I've been playing around with one test class. I commented out the ClassInitialize() and ClassCleanup() methods. I rewrote one test method and mocked everything. I tried running just that one test. I still got the "The agent process was stopped while the test was running" error.

Visual Studio 2010, version 10.0.30319.1 RTMRel

Test framework: integrated VS 2010 MS Test

Mocking framework: Not using mocking, I have a db that is destroyed and recreated in MyClassInitialize(), it is populated with known values. Yes, I know I should be using mocking, but this is an older app and it has not been updated with all of the new bells and whistles yet.

DB Framework: NHibernate

Target Framework is 3.5 for all projects in this solution except for the test project.
The target framework is 4.0 for the test project. I tried changing it to 3.5, it will not let me.

"Attempted re-targeting of the project has been canceled. You cannot change the specified .NET framework or profile for a test project."

C# - After Deploying 4 Web Application To IIS6 Server Worker Process Recycles Cause It To Stop Working Most Of The Time?

Jul 8, 2010

This is a really odd situation, so hopefully I can explain it well enough.

I am deploying an ASP.NET 4 webforms application to a Windows Server 2003 SP2 server running IIS6.

Here's the problem -- when the application pool recycles its worker process (w3wp.exe), about 80% of the time, I will get an ReflectionTypeLoadException error trying to access any page in the app that contains an EntityDataSoure every time I try to view it.

However (this is the interesting part) -- the other 20%, it works just fine. I've actually resorted to turning off recycling the worker process entirely for this application pool and just add/remove whitespace from web.config forcing the site to recompile until I get a "good" w3wp.exe.

If this isn't clear, what I'm saying is: the actual worker process doesn't work at all for pages containing an EntityDataSource for about 4/5 times it starts, but still manages to serve all other pages just fine. Once you get a worker process that manages to serve a page with an EntityDataSource, it works every time until that process gets recycled.

My question is, how can I debug this? It works fine on my dev machine, it works fine on the server as long as you get a good process running, but iisreset or a server restart or anything that kills the worker process is almost guaranteed to cause the site to not come back up and throw this ReflectionTypeLoadException.

Databases :: Secured Oracle Provider/ Encrypts The Data While Passing Data Over Internet?

Aug 27, 2010

Ours is a Asp.net web application. Database is Oracle. Its an Internet Application.

Database will be in one location and Web application in another. Data from Oracle to Web application will be passed over Internet.

We are using EnterpriseLibrary. And provider is System.Data.OracleClient.

We need a provider which encrypts the data while passing data over internet.

Do we need to go for some third party Providers or ODBC ?

Looking For EF Provider For Oracle

I'd like to know if there are any good EF providers for Oracle out there, and more specifically what experiences people have had with them. We're looking for a provider that is either free or paid for, but I'm struggling a bit with finding any real opinions on what the different frameworks are like to work with in a production environment.

EDIT,I should clarify that we are using Oracle 11g.
