Re: [ovirt-devel] oVirt messages from engine to vdsm

If the engine user is not accessible directly, why then in this command you use it?: psql -U engine engine -c "UPDATE vdc_options set option_value = 'false' WHERE option_name = 'SSLEnabled';" I am not really good in managing databases, I also didn't have postgresql installed after finishing oVirt engine installation and even managing to deploy everything. Does it mean that no database was created at all? I have chosen automatic and local creation in all fields related to database while installing oVirt engine.
