EXAMPLES

MySQL
First you need to specify the database parameters in /etc/oar/oar.conf. These parameters
will be used by oar-database.

To create a new database (assuming that the MySQL root password is PASS):

oar-database --create --db-admin-user root --db-admin-pass PASS

To upgrade an existing database:

oar-database --upgrade

PostgreSQL
First you need to specify the database parameters in /etc/oar/oar.conf. These parameters
will be used by oar-database. If your PostgreSQL database is on the local system, you can
use the --db-is-local option which will use PostgreSQL unix account (needs root
privileges).

To create a new database:

oar-database --create --db-is-local

To upgrade an existing database:

oar-database --upgrade

Advanced usages
To make some tests or to administrate several databases, you can also specify the sql
parameters on the command line. For example:

oar-database --create --db-type=Pg --db-host=HOST
--db-user=oar --db-pass=PASS
--db-admin-user=ADMIN_USER --db-admin-pass=ADMIN_PASS

will create the oar database and the oar user on the postgresql system hosted by HOST. The
user ADMIN_USER must have the right to create new databases and new roles on this system.
