SYNOPSIS

       oar-database --create  [OPTIONS]

       oar-database --drop    [OPTIONS]

       oar-database --setup   [OPTIONS]

       oar-database --reset   [OPTIONS]

DESCRIPTION

       --create
	   Create and initialize a new database/user.

       --drop
	   Drop an existing database/user.

OPTIONS

   General parameters
       --conf=OAR_CONF_FILE
	   Define the oar configuration file to use. By default /etc/oar/oar.conf is used. This file doesn't exist, the default parameters for
	   each value are used.

       --update-conf
	   The database parameters given in the command line are writen to the OAR_CONF_FILE

       -h,--help
	   Display this help.

       -d,--debug
	   Display more information during the script execution

       -f,--force-sql
	   Force to resume the execution even if an sql instruction fails

       -y,--force-yes
	   This option will cause oar-database to continue without prompting if it is doins something potentially harmful

   Database admin parameters
       These parameters are only needed for database/user creation or removing.

       --db-is-local
	   For --create or --drop, this option tells that the database is local. oar-database can use local admin account to execute command
	   (useful for postgres).

       --db-admin-user=DB_ADMIN_USER
	   For --create or --drop, this option gives the privilegied user to use.

       --db-admin-pass=DB_ADMIN_PASS
	   For --create or --drop, this option gives the privilegied user pass to use.

   SQL parameters
       By default, if not specified, all the sql parameters are taken from the OAR_CONF_FILE. It is preferable to set these values directly to
       this file.

       --db-type=DB_TYPE
	   The type of the SQL database. It can be currently, mysql or Pg (for postgresql).

       --db-user=DB_USER
	   Connect to the database as the user DB_USER instead of the one given in OAR_CONF_FILE. By default, if OAR_CONF_FILE doesn't specify a
	   user, it is oar.

       --db-pass=DB_PASS
	   Connect to the database with the password DB_PASS instead of the one given in OAR_CONF_FILE.

       --db-host=DB_HOST
	   Connect to the database on the host DB_HOST, By default, if OAR_CONF_FILE doesn't specify a host, it is localhost.

       --db-port=DB_PORT
	   Connect to the database on the port DB_PORT, By default, if OAR_CONF_FILE doesn't specify a port, the value depend on the DB_TYPE. if
	   DB_TYPE is mysql, DB_PORT is 3306. If DB_TYPE is postgresql, DB_PORT is 5432.

       --db-name=DB_NAME
	   Connect to the database on the host DB_HOST, By default, if OAR_CONF_FILE doesn't specify a database name, it is oar.

       --db-ro-user=DB_RO_USER
	   same as --db-user except that it is for the read only access.

       --db-ro-pass=DB_RO_PASS
	   same as --db-pass except that it is for the read only access.

EXAMPLES

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

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

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

       To upgrade an existing database:

       oar-database --setup

   Postgresql
       First you need to specify the sql parameters in /etc/oar/oar.conf. These parameters will be used by oar-database. Then if your postgresql
       database is on the local system, you can use the option --db-is-local (otherwise, the procedure is the same as Mysql). So oar-database will
       use the postgres unix user to administrate the database (you need privilegied access to the local system).

       To create a new database:

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

       To upgrade an existing database:

       oar-database --setup

   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.

FILES

       /usr/lib/oar/database/mysql_structure.sql, /usr/lib/oar/database/pg_structure.sql
	   SQL instructions for creating the structure of the oar database.

       /usr/lib/oar/database/mysql_default_admission_rules.sql, /usr/lib/oar/database/pg_default_admission_rules.sql
	   SQL instructions for inserting the default admission rules in the oar database.

       /usr/lib/oar/database/default_data.sql
