Yes, after every update of the source code, you must update the database.

Stop this process after the upgrade completes.

Your final command would be one of:

sudo /etc/init.d/openerp-server start
sudo service openerp-server start

i launch the command but nothing happen, the command does nothing and return seems stuck i launch command as openerp user

update : it seems stuck because i have to start open-erp before launch command

have to launch command as root or openerp user ??

but i have this error as openerp user :

dministrateur@SSGVERP:~$ sudo su openerp
[sudo] password for administrateur:
openerp@SSGVERP:~/v7/server$ ./openerp-server -c /etc/openerp-server.conf -u all -d brestaim

You need to stop your running OpenERP server and after that start your OpenERP server with the ./openerp-server -c /etc/openerp-server.conf -u all -d brestaim

You get the message that OpenERP is running: [Errno 98] Address already in use

You can use the command ps aux | grep openerp to see if an OpenERP instance is running.

If you need more help just reply.
