Running IQConnect from a windows service May 20, 2011 11:49 AM

Jay & Steve, Thank you for your support. We detected an issue on our side, fixed it & are now no longer seeing any issues. We'll keep it running day&night for a couple of days so we can confirm everything is OK, but it looks like we're out of the woods. The issue we were having is that we unknowingly kept instantiating your COM components as well as trying to start IQConnect. It was not obvious because our service was running on a schedule and it somehow slipped of of my mind that instantiations could have been (and were) happening at each schedule interval. Again thank you so much - you've been great. I'm thinking our job is done :)

Unwatching & relooking was an idea on how to get new futures when they come in. The 15 second interval is ridiculous naturally, but I've used it on purpose to make sure the mechanism is working for us, and working well.

Posting a simplified solution showing closely what we are doing. I've replaced all of the processing we are doing with simple Console.WriteLine lines. Please run the solution and you'll notice 2 issues (put in some real credentials in Program.cs): 1. Memory consumption for IQConnect is going up & down but is steadily increasing, which suggests a memory leak. 2. Within minutes after starting we start receiving only symbol lookup results. No timestamps, no quotes. It looks like DTNIQFeedCOMLib.LevelOne stops working for some reason. Need to get to the bottom of this ASAP. Please advise. Any way I can contact developer support by phone so we can accelerate the process?

K, makes sense. Will take a look at that one. Anyway we can proceed pushing on the login issue?

Wow just saw IQConnect process eating up 1.3G of RAM !? Had to kill the process and restart our app. MAJOR ISSUE!

It was by design to try & restart the IQconnect on 15 sec intervals. Since then I changed it so that I only connect once when I start the service, but I'm still noticing the same type of issue. Will see if can be authorized to send you at least a part of the project, but not sure if I will be since it's a proprietary code. Anything else we can do without me sending out the sources?

Working fine. Thank You. Now seeing occasional IQConnect crashes followed by restarts (attaching crashlog): Faulting application name: IQConnect.exe, version: 4.7.2.0, time stamp: 0x4c926df4 Faulting module name: IQConnect.exe, version: 4.7.2.0, time stamp: 0x4c926df4 Exception code: 0xc0000005 Fault offset: 0x0000d79c Faulting process id: 0x14b4 Faulting application start time: 0x01cc141e47d55850 Faulting application path: C:\Program Files\DTN\IQFeed\IQConnect.exe Faulting module path: C:\Program Files\DTN\IQFeed\IQConnect.exe Report Id: 3355ff3a-8013-11e0-87da-90e6ba25231c Not something I would like to deploy this to production environment :) Any way I can at least programmatically capture this type of event (all I'm using is DTNIQFeedCOMLib.SymbolLookup3 & DTNIQFeedCOMLib.LevelOne)? If nothing else I would like to catch this type of situations an alert our tech team of a possible issue. This is what I've been trying (no luck though because the ErrorDataReceived doesn't get triggered): System.Diagnostics.ProcessStartInfo processStartInfo = new System.Diagnostics.ProcessStartInfo( _IQConnectPath, string.Format( "-product {0} -version {1} -login {2} -password {3} -autoconnect -savelogininfo", _AppName, _AppVersion, _Username, _Password ) ); processStartInfo.WorkingDirectory = iqDirectoryPath; processStartInfo.UseShellExecute = false; processStartInfo.ErrorDialog = false; processStartInfo.RedirectStandardError = true; _IQConnectProcess = System.Diagnostics.Process.Start(processStartInfo); _IQConnectProcess.EnableRaisingEvents = true; _IQConnectProcess.ErrorDataReceived += new System.Diagnostics.DataReceivedEventHandler(IQConnectProcess_ErrorDataReceived); _IQConnectProcess.Exited += new EventHandler(IQConnectProcess_Exited);

Hmmm perhaps not after all... Registry setting made it so that I no longer have collisions, but now my app won't connect to IQConnect. The collision was on port 9100, which i changed in registry to 9400. I'm using DTNIQFeedCOMLib.SymbolLookup3 (which as I understand connects to port 9100). How do I make SymbolLookup3 connect to 9400?

Nevermind, got it - it's also a registry setting. Changing the port was the last missing piece. Got it all working now. Thanks!

Thank you! Setting both -autoconnect & -savelogininfo seems to have did the trick. We now seem to have port collisions with another app on our server (port 9100). How can I change IQConnect's default ports?

We've been integrating IQFeeds with our aaplication lately and bumped into a MAJOR problem. Our application works great, when we are running IQConnect from a regular windows session (ie running iqconnect.exe from command console while being logged on to windows under a developer user account). While running iqconnect this way we get a "IQ Connect Login" screen which has all of the information prepopulated, but still requires us to press a Connect button (see the image attached). This is a command lie we are using (registration info replaced with XXX): "C:\Program Files\DTN\IQFeed\iqconnect" -product XXX -version 1.0 -login XXX -password XXX -autoconnect We are running the latest version (4.7.2.0). It is essential for our system that we can guarantee the IQConnect is running on a server machine without any user interventions. Trying to achieve that we've been running IQConnect both as a scheduler job and starting it from a windows service created as a sort of a watch dog. When started like this, the iqconnect.exe process can be seen from Windows Task Manager, but we can NOT connect to it from our applications. I'm assuming IQConnect has started but is still waiting in the background (no window or tray icon appearing) for someone to press that Conenct button. Is there a way we can make it so that it autoconnects (the -autoconnect switch does NOT help)? To reiterate: - When running iqconnect from interactive windows session everything is fine, except we need to click on Connect button. Other than that we got the feeds going. - When running it from a non-interactive session we cannot connect to it. It is critical to resolve this IMMEDIATELY. Please advise. Thanks, Djordje |
