Server won't start after upgrade to 4.0 from 3.17

rjk6 years ago

I'm unable to get the server to work correctly after trying to upgrade to version 4.0. The log doesn't show any errors, here's what it shows:

What about wrapper log file?

rjk6 years ago

How much of it do you want? I found this error in there:

I don't want any of it. I'm just giving you suggestions where to look for the problem.

Well, I don't know how to fix that error which was caused after the upgrade. Is it a bug?

Anton Tananaev6 years ago

We upgraded more than 10 servers so far without any issues. More likely you are doing something wrong, but of course there is a tiny possibility that it could be some bug.

rjk6 years ago

Well, I took a backup and then ran the new ./traccar.run file to do the upgrade, like I always do. There's not really anything to get wrong. What can I check, or should I just revert back to 3.17 and never upgrade again?

Anton Tananaev6 years ago

Sounds like you haven't read official documentation about upgrading Traccar. I would recommend you start from that, if you are interested in upgrade.

rjk6 years ago

OK. After reverting back to the old version, and still having the issue happen again, I think the problem is that my JVM went from version 1.8.0_181 (Java 8) to version 10.0.2 (Java 11) after an OS upgrade. I will see about downgrading the JVM and then try the new traccar version.

Hi Anton, rjk could have right. I have just updated my traccar successfully from version 3.15 (previous updates: 3.7 -> 3.11 -> 3.15) to 4.2 and encountered the same error in scenario: 3.15 -> 3.17 -> 4.0. Directly updated traccar from 3.15 to 4.2 throws errors about not existing user table when trying to log in. Proper upgrade path was 3.15 -> 4.0 -> 4.2. Hope it will help someone with an update.

What do you mean by "the same error" exactly? Please provide error logs.

Hi Anton,

I meant this:

there is only:

Still, I was able to update Traccar, but maybe that's what other users complain about from time to time.

Try removing foreign key constraints.

Lucas B.5 years ago

It works, but you need to remove the constraint on the database before starting the new version of Traccar. If you have got the error during the start of Traccar, it throws the same error during connecting to H2 database as well:

When I have copied the database and did it before starting Traccar 4.0:

liquibase was able to update database and Traccar 4.0 has started. Seems like it's some bug in the update procedure of Traccar.

Version 4.0 is an old one. Do you get problems with upgrading to 4.2? If yes, I need to know steps to reproduce because it works just fine for me.
