[SOLVED] Location of cache files (Linux)

[Trigeek00]

Hello,
I have noticed some odd behavior of UMS in my media server display. When I click on a work by Beethoven, I get the artwork for an album by Pat Metheny. Sometimes the album title and artist does not match. It did not happen at first, however I was re-arranging my folder structure and that is when the problem showed up. I modified the UMS.conf file to disable cache and the problem went away, re-enable cache and it's back. With the cache disabled the folders load slower... not a surprise.

I think the problem is the cache is having an issue due to my moving of files. I suspect that clearing the cache and letting it rebuild would fix the problem, though I cannot find it's location. I have searched the forums and have only found answers for Windows and OSX. Could someone please point me to the location of this file? I am running Ubuntu Server 18.04. Could you also confirm that I need to delete the file to force a new cache rebuild.

Thank you in advance,
Jim

On my Gentoo Linux it is in:
/username/.config/UMS/database/

Thanks for you reply. I do not see the .config directory under my home. What was the name of the database file that you reference?

Thanks

All file and folders starting with a "." is hidden in Linux. Try using "ls -a" or simply "cd .config" despite not seeing it.

I do not see a .config directory on my Ubuntu Server. It is there on my laptop that has Ubuntu Desktop. So at least in my case, it's a question specifically about Ubuntu Server.

It will be created in the home folder of the user UMS is running as. That means, if you run it as root, look for it in the "/root" folder, otherwise look in the "/home/<username>" folder. It's also explicitly listed in the log during startup. Look for "profile folder".

The name of the files are:
medias.mv.db
medias.trace.db

Maybe try the find command from each user:
find -name medias*

EG:
satan ~ # cd /root
satan ~ # find -name medias*
./.config/UMS/database/medias.mv.db
./.config/UMS/database/medias.trace.db

Thank you everyone. Especially Boss..

Knowing the file names was just the ticket. The files were located in my /etc/databases directory. I had seen the files earlier though I was expecting "ums" in the filename. Problem is solved!
