UMS 6.0.0 doesn't run

UMS doesn't run anymore since updating to 6.0.0

We need a bit more information...

[mschumacher69]

What kind of information do u need? I'm on Windows 7 64-bit and Java 8. When I upgrade to 6.0.0, clicking on Universal Media Server from the start menu does nothing, I don't see the UMS icon in the notification area to be able to access the UI.

I re-installed 5.5.0 for now.

[Nadahar]

Just that helps. If you ever feel like troubleshooting this furter, attach this file here after trying to start 6.0.0:

Code: Select all

%programdata%\UMS\debug.log

In addition you can check that UMS isn't installed as a service (you can do this without reinstalling 6.0.0). Do this by running "services.msc" and look for "Universal Media Server" in the list of services.

Thanks for the tip. I attached the file. I noticed this error:
Database connection error: Data conversion error converting "C:\Users\M.Schumacher\Videos\07-01-2010 1.avi" [22018-191]

This might be what's causing it to fail.

Should I try deleting/renaming this file?

[Nadahar]

No, the easiest thing to do is just to delete the database file. It will recreate itself, and the content is just the "cache" containing information about your shared files. It will repopulate itself as you browse, or a manual scan can be started.

The database file is:

Code: Select all

C:\ProgramData\UMS\database\medias.mv.db

[mschumacher69]

I don't have medias.mv.db in there. I have medias.h2.db and medias.trace.db

[Nadahar]

Ok, just delete both medias files.

[mschumacher69]

OK that worked, thanks a lot for your help! What caused this? Is it an issue with the file itself or a bug in UMS 6.0.0?

[Nadahar]

The version of the database has been upgraded in UMS 6.0.0, and apparantly the database engine upgrades some information/structure in the file itself. There was probably already some error in your file that prevented that upgrade from working as intended. There are tools for "repairing" the file that might have succeeded, but because of what UMS stores in the file (all can be rebuilt by UMS) there's no need to go into that.
