I'm going through the Web Farm enabling documentation and there's a reference on how to configure the web.config to use the BroadcastPollingCachingProvider. It shows that the provider is located in providerPath="~\Providers\CachingProviders\BroadcastPollingCachingProvider\" however in the 4.5.5 install I don't see those files at all. I see that the DLL for the provider in in the application bin but that's about it.

Any clues where I can find these at?

I'm setting up a web farm as well.  I too, have decided to use the "Broadcast/Polling Based Caching Provider", even though I'm using a central file system, because the "File-Dependency Based Caching Provider" caused too many exceptions.  Like the original post, I get stuck at this step in the web farm doc "Open the following text file in notepad: “$root\Providers\CachingProviders\BroadcastPollingCachingProvider\Providers\SQLDataProvider\ 03.01.00.SqlDataProvider", because this file does not exist in the file system.  I imagine the dotnetnuke.com team uses a web farm.  Is there no one out there that can shed light on the "File-Dependency Based Caching Provider" exceptions experienced, or what to do for "Broadcast/Polling Based Caching Provider" for newer versions of DNN where the SQL script is not included in the file system?

Thanks
Rick

You need to download the complete source version of the DNN version you are interested in.  In the zip file you will find the website folder and a library folder.  Navigate through the library folder and you will eventually find the files your are after.

The DNN doco on this and the general information available and responses to questions about the BroadcastPollingCachingProvider is very poor!  If DNN really want's to be an enterprise level solution they really should do something about this ASAP!

Good luck getting it working, we have followed the doco and now my Broadcasts table gets over a million records a day in it and won't clear as SQL Server times out.  If anyone else has actually had success using the BroadcastPollingCachingProvider it would be great to know as I am about to give up on it all together.

 Oren,

 

Did you give up on it or did you get the BroadcastPollingCachingProvider to work? I am in the same boat. I have a rather rapidly increasing Servers table that is not purging. I don't even see a stored procedure that is in place to handle purging of the servers table. Please fill me in on what you were able to do to get DotNetNuke functioning correctly in a webfarm environment.

Thanks!

We are having the same issue with the broadcast table growing and never being cleaned up. The DNN scheduled task to clean it is running right now, but once the broadcast table gets to big, then the scheduled task fails and never cleans up. On top of that the broadcast polling caching provider does not keep all servers in our farm in sync. We add a page on one sever and it sometimes, after a few minutes shows up on one or 2 of the other servers.

If anyone knows where we can get more detailed documentation on the broadcast polling caching provider that would be great.

Thank you,
