In the manual there is a short description on how to move the server property "SystemFolder" to a new directory:

The path to a folder where will be stored databases managed by Valentina Server.

If you change it, you should copy/move existing databases there yourself. Also, you should unregister all databases and register them back, because the master database keeps the full path to the databases inside.


I thought I'd make a somewhat more detailed description:

- Remove all connections.
- Unregister databases.
- Move databases to new directory.
- Change directory for server.
- Restart server.
- Register databases.

Do I need to move master.vdb, too? Do I need to move or copy the databases?

I some testing today to change the directory and must have forgotten or mixed up a step. I ended up with this funny result where the databases are at different locations. See screenshots.

I then deleted the new directory. Which makes even funnier results: the data is written to dev/null and I have databases which can be created but not opened.

I don't think that changing the main database directory works in 13.6. I reset the directory to the original database folder and changed the directory again. This time I managed to get into the lovely hell where Valentina Server starts and stops a couple of times per minute because it couldn't create the master.vdb. Which was in the new directory.

Hi Beatrix,

Yes, the wiki must be improved with a more detailed description - of how to change properties like SystemFolder properly.
BTW, your steps seem to be correct.

I cannot reproduce your issue - it works for me, so:
- can you describe the steps in detail?
- could you send me the server logs (verbose mode = 3)?
- how do you restart vServer?

I'll make more detailed steps and then I'll send the logs. I restarted Valentina Server by using restart and by shutting the server down and then restarting it.

I actually had the same error a couple of weeks ago with the same result. This was with 13.5 and not 13.6.

Regarding master db.

Most simplest way is to let vServer create a new master db in the new location. But you lost users credential data in this case.

A more tricky way is to move master db as well.
- But note, vServer always keeps master db open, so you should stop vServer first, then move master db (BTW, it can be done for all databases - moving files after vServer stops).
- In the master db you have a single record in sysdatabase table - a description of the master db itself. So you should manually change fld_path there.

After vServer starts:



use master;

update sysdatabase set fld_path = 'new_path/master.vdb';


Now, you can register moved databases...
