Problem in profiling WebService! Exception thrownby Profiler

  Hi Sachin,
  
  Firstly, let's look at the IIS side of things. After you try to start profiling (but before the timeout happens), could you check in task manager to see whether another w3wp.exe process gets started? (You might need to discount any previously running as part of IIS)
  
  Could you also check the event log for any other errors from W3WP, ASP.NET, IIS or similar that occur at around the same time as you start profiling?
  
  Secondly, when you try and use WebDev, what error do you get there? They're probably unrelated, but might not be...

  SB: No i dont see a single w3wp.exe in task manager under process section.

  SB: No there are none.

  SB: I ran it, and it is working fine now, y'day I was not taking snap shots... now I took and got the results.
  
  But we are really interested in doing it by IIS.
  
  Hope it help you to investigate...

  Hi,
  
  Thanks for the reply.
  
  One question first: are you running IIS in IIS 5 Isolation Mode? If so, you'll need to select "IIS 5" in the ANTS Profiler Wizard rather than IIS 6.
  
  If not, if you could open up a command prompt on your machine, and try the following from the C:\WINDOWS\system32\inetsrv directory:
  

  w3wp -debug -d http://*:9120/ -s 1 -ap "RGTestAppPool"
  

  
  See whether that starts up (at which point you should be able to surf to your site at http://localhost:9120/), or whether it throws an error. This is not profiling it at this stage - it's just trying to get a better idea of what's causing the problem.

  I am using IIS6.0
  
  I entered the command in command prompt. it did nothing just came out to the next line.
  
  Then I tried accessing my Web service, i could access it well.

  Hi,
  
  Do you mean it terminated instantly and returned you to the command prompt, or remained running but with no output? (The latter is what I'd expect.)
  
  Also, can you confirm what port the web service was originally running on? The logs posted on the other thread suggest it was originally on port 80, and that you're trying to profile on 8013. However, the logs below suggest a timeout on 9120.
  
  One other thing... are you running at least Windows 2003 SP1? SP2 is also fine, but pre-SP1 had some issues. That said, I'd expect a different problem if that was the case.

  Hi Rob,
  
  I am now getting confused... I think I am making some small mistake somewhere...
  
  Let me explain you what I am doing...
  
  I did this
  w3wp -debug -d http://localhost:9120/ -s 1 -ap "DefaultAppPool"
  and control came out immediately. I dont know whether I should mention it as a crash/terminate. But it gave me cmd prompt immediately. There was no error msg.
  
  I am using WindowsNT SP1
  
  I am running my web service on 80 port. but we need to mention a different port for profiler so i mentioned 8013(it can be anything, i believe).
  
  I dont have any idea regarding: "the logs below suggest a timeout on 9120."
  I think my log files which i posted at
  "http://www.red-gate.com/messageboard/viewtopic.php?t=4551"
  says:
  3/27/2007 1:51:38 PM ENGINE - Caught Exception in ProfilingSession: Timed out waiting for port 8013 on 127.0.0.1 to become available

  Hi,
  
  OK, that's not what should be happening then. For me, this happens if the port is already in use. You'd think it'd give an error message, but apparently not .
  
  I'd got the port 9120 from the event log entry below: "Unable to start profiler - exception details RedGate.Profiler.Engine.IIS.PortTimeoutException: Timed out waiting for port 9120 on 127.0.0.1 to become available"
  
  Could you try running the w3wp command again with port 8013 instead of 9120? (If it stays running, you'll need to terminate it with Control-C before trying to profile.)
  
  It might also be worth trying to profile on a completely different port to anything you've used anywhere else - e.g. 12345 (must be less than 65535).

  Hi Rob,
  
  The event vrw log you were saw was very old. Actually i was trying plenty of things, so might have given 9120 port.
  
  The latest error msg in EventVwr for port 8013 is:
  
  Unable to start profiler - exception details RedGate.Profiler.Engine.IIS.PortTimeoutException: Timed out waiting for port 8013 on 127.0.0.1 to become available

  I hope it will help...

  Hi,
  
  Thanks - that clears up the port number confusion.
  
  If you could run in a terminal (in C:\windows\system32\inetsrv):

  w3wp -debug -d http://localhost:8013/ -s 1 -ap "RGTestAppPool"
  

  
  (note RGTestAppPool rather than DefaultAppPool is deliberate, and also port 8013)
  
  That should not terminate immediately - if it does, check your event viewer "Application" log for entries coming from W3SVC-WP.

  Nothing happened. I just pasted the command as-is given by you in cmd prompt (both at cmd as well on VS cmd) and pressed enter. It came out immediately, doing or showing nothing!
  
  What next

  In that case, I'm at a bit of a loss. It sounds like an issue with IIS, since that should definitely work.
  
  More things to try:
  
  1) Reboot your machine (the old classic )
  2) Run "netstat -a" in a command prompt. Look for any lines that mention port 8013.
  3) Try connecting to port 8013 using telnet - in a command prompt, "telnet localhost 8013". If it connects, it will blank the terminal, if not, it should give some error like "could not open connection". I'd hope you'd get a "could not open connection", since that port shouldn't be in use.
  
  I'm afraid I'm running out of ideas beyond those - if you have another machine running IIS 6, you might like to give it a go on that, or even a virtual machine (though I don't guarantee the accuracy of profiling results taken inside a VM).

  1) Reboot your machine (the old classic )
  SB: I tried on 3 different machine but of no avail.
  
  2) Run "netstat -a" in a command prompt. Look for any lines that mention port 8013.
  SB: no where mentioning of 8013
  
  3) Try connecting to port 8013 using telnet - in a command prompt, "telnet localhost 8013". If it connects, it will blank the terminal, if not, it should give some error like "could not open connection". I'd hope you'd get a "could not open connection", since that port shouldn't be in use.
  SB:- you are right i got a msg "Could not open connection".
  
  
  Apart from this tell me one thing:
  If our webservice is running on port 80, what number should we enter in Dialog box "Profile an ASPnet application in IIS" screen 3rd, while running profiler. I think it should be any port which is free. right!
  
  Secondly, I read some where that you should give previlage to some IISMetadata, is that the case

  2) Good, that's what I'd hope
  3) Also good
  
  Port number: yes, that's entirely correct. 8013 is the one we choose as a default, but any free port should be fine.
  
  One of the things we need to do is to read the IIS Metabase which obviously needs appropriate permissions to do so, but this is happening fine in your case - it's extracting the site ID appropriately.
  
  Are the computers in question members of a domain? Do you know of any security policy restricions in place beyond what comes as standard?

  Hi,
  
  It might be helpful to see if the application pool had been started, but for some reason isn't answering requests.
  
  If you go through the wizard and choose the ASP .NET web application as the type of application to profile, enter the URL to the webservice in the path (it should appear in the dropdown list), verify the .NET Framework and IIS versions are correct, and that you can run web applications on the selected port, go through the next screen and click finish, you should see the w3wp process running for your web application.
  
  The way to check to see if the application pool is running is to open a command prompt, change working directory to %systemroot%\System32, and run

  cscript iisapp.vbs

  One of the application pools listed should be RGTestAppPool, like Robert had said. If not, then Profiler is not starting the application pool for some reason, maybe because of a user rights issue.
