Re: [Cs-studio-users] ArchiveEngime configuration with multiple IOC servers

[<zun...@es...>]

Dear Kay,

Thanks for the explanation. I configured the broadcast addresses but it
still seems that the engine is not getting data or that is not writting
anything to our DB.  Is there any easy way to know which to the two is the
problem? (like redirecting to a text file the data)

I attach the conifguration file and the log with the debug detail.

Thanks

The output on the console is:
