Hi,
I don't understand what you are trying to do, but it shouldn't be that
complex. You can use the sqlite3 command to access the default DB:
$ cd /var/lib/one/
$ sqlite3 one.db ".schema"
Maybe your compilation with mysql=yes is not working because you are
missing some dependencies, like libmysqlclient-dev... check [1] & [2] for
the complete list of requirements.
And OpenNebula does not use any DB environment variable, just the
configuration in oned.conf. At the moment, only sqlite and mysql are
supported.
On a side note, if you want to read the DB for accounting or statistics
that's fine, but if you modify it while opennebula is running, opennebula
won't notice and the differences between the cached objects and the DB will
surely lead to erratical behaviour.
Best regards.
