Failed Recordings

[JonRoyle]

Since you are serving this via IIS you could try to disable EWA within GBPVR itself......that will turn off the native GBPVR web server....perhaps there is conflict going on between the two......

UJB - thanks for the suggestion. I tried that but it has made no difference. From the analysis done so far I appear to have two issues

SQL lite becoming lock

• ed (generic GB PVR issue) - service restart clears the lock
  
• EWA via IIS not being able to create DB journal files (EWA issue - I am guessing journalling has just been
  

enabled in latest version of GB PVR)

I will raise the first one in main support forum, but the 2nd one appears to be more of an EWA issue

[UncleJohnsBand]

To my knowledge journaling has always been enabled....and since the issue appears to occur consistently via IIS and sometimes via the native GBPVR web server then I would suspect it is an IIS configuration issue or security issue on your machine....especailly since I don't have this issue showing on my dev machine which runs both IIS and the GBPVR web server.

Is this only happening with the newest release of GBPVR (which is using build 53 of EWA)?

EDIT: One other thing I just thought of......on my machine running IIS I have the ASPNET user with Administrative rights.......try that and see if it goes away.....if it does then you know it is defiantly a security thing....

UJB,

It has only started to happen when I upgraded to latest version GBPVR 95.5 and EWA 54. If I go back to old versions (GBPVR 98.13 and EWA 52) everything works fine

I have granted IUSR and Everyone full Domain Admins access but this has had no affect.

I will do some more testing with different versions of EWA and GB-PVR and report back though this is likely to be tomorrow now as the kids are currently using the MVP.

Thanks for your assistance.

NB My set-up
Win 2003, Nova-T PCI DVB card, Plugins: MusicLibary2 v4.4, Weather v4.0 ( 98) and AddEpisode v0.7010. 750GB RAID-5 disks

Very strange.....nothing has changed that would cause this behavoir.....:confused:

UJB,

I have done loads more testing and while I still have the issue of recording programs via EWA/IIS failing and corrupting GBPVR DB I am getting somewhere...I think

With a clean install of GB-PVR 98.13 and also 99.5 with nothing carried from my old configuration EWA/IIS consistently fails in both cases. So this is not an upgrade issue. [Struggling to reproduce it working now :confused: - I have a server DR disk but that would be a bit drastic!)

The issue looks to be one of permissions with the IIS user having insufficient permissions on the SQLlite DB. It also has insufficient permission to access the 'Config' page on EWA - error message "Firefox has detected that the server is redirecting the request for this address in a way that will never complete."

I don't believe there are any NTFS permission issues as I have tested with IUSR and IWAM accounts as Domain Admins and given Everyone full permission to the GBPVR directory.

Are there any verbose EWA logs that I can look at to diagnose further? You mention that you are using IIS for development, is this IIS6? I am using the same veriosn of .net as yourself (based on previous screenshots of yours).

Many thanks,

Jon

My 2cts: My ewa logs are in:
c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\gbpvr\4d107d39\801bf7b5\assembly\dl3\c1465f65\00e52788_5c22c701\logs\

So they are not in the gbpvr dir. Maybe it still is a permissions issue.

Not using IIS 6......we just switched to IIS6 at work a couple of months ago.....you should have fun figuring out what permissions are needed.....IIS 6 does need a bunch more permissions.....

Luckily there is cool tool to help figure out what is getting accessed that does not have permissions....

Sysinternals (now Microsoft) offers a free tool called Process Mon that will let you see everything that is going on......you should be able to see what is causing the hangup.

ProcessMon

You can also use FileMon which was replaced by ProcessMon. But it may give you more direct file related results.

HtV & UJB,

Many thanks for your help.

I found the EWA logs but unfortunately they are not verbose enough to capture the fails.

I am confident the issue is permissions though I think it is as the DB/App level so I won't be able to resolve on my own.

I have done some captures of accessing the Config screen and scheduling a recording from both IIS and GBPVR web server. The results are very different. The IIS trace uses the 'Network Service' rather than 'System' account and gets bogged down in the DB and never progresses to GB PVR app. If you have the time to persue I will post the traces (CSV files) - When you access the Config screen from IIS pages you can see the 'Buffer Overrun' error.

Regards,

Jon

PS ProcessMon is a great tool and added to my Utilities collection

Have you tried setting the site to run in IIS 5 mode.....if I recall correctly there is a way to do that.......

Edit:

Also...perhaps reviewing this will help: http://technet2.microsoft.com/WindowsSer...x?mfr=true
