# ownCloud Administrators Manual

# Default Parameters

The following parameters are automatically configured by ownCloud upon the initial admin login. These parameters are mandatory for the ownCloud instance to operate properly.

Parameter | Format | Description
Debug | define(“DEBUG”, true); | When set to true, additional information is written to the logs. This is to be used only for local development and not in a production environment.
Installed | “installed” => false, | This flag indicates whether the ownCloud instance was installed successfully. When set to true, the install was successful. When set to false the instance is not properly installed.
DB Type | “dbtype” => “sqlite”, | The dbtype indicates what type of database is being used with this install.
DB Name | “dbname” => “owncloud”, | The ownCloud database within the SQL instance. ownCloud database configuration guides use “owncloud” in the instructions, it is the default for this field. This may be set to any valid table name. If the table does not exist, the setup will attempt to create it, provided it has proper permissions.
DB User | “dbuser” => “”, | This is the user that ownCloud uses to write to the database. This must be unique across ownCloud instances using the same SQL database. The user will be created when the install wizard is complete. Since the database user in the initial login screen has admin privileges (root), ownCloud creates a new user to ensure ownCloud does not run with unnecessary database permissions. ownCloud prefixes “oc_” to the userid to prevent a collision between the ownCloud admin user and any existing database users. This is generated at the time of the initial login and is the Admin User as entered by the ownCloud admin.
DB Password | “dbpassword” => “”, | When a new database user is created for ownCloud, a password for the database is generated by hashing the admin user password. This hash is stored in this parameter.
DB Host | “dbhost” => “”, | This parameter shows the location of the database. Can be an IP pointing to the database server, a Fully Qualified Domain Name (FQDN) or localhost.
DB Table Prefix | “dbtableprefix” => “oc_”, | All tables in the database will begin with this prefix. By default the prefix is “oc_”. If this prefix is changed in the config file, the tables in the database will need to be manually renamed. ownCloud will not detect a change to this option so changing this prefix without manually renaming the tables will break the instance of ownCloud.
Password Salt | “passwordsalt” => “”, | This is the salt used to hash passwords within the ownCloud instance. It is important not to remove or lose this password. If lost, all passwords within the ownCloud instance will be lost.
Data Directory | “datadirectory” => “”, | This parameter tells ownCloud where the default data directory is located. It is configured in the installation wizard. If using SQLITE, the database is stored in this data directory as well.
Trusted Domains | ‘trusted_domains’ => array ( 0 => ‘A.B.C.D ‘, ), | This parameter identifies trusted URL for ownCloud which users may log into. The initial entry ‘0’ is automatic. If it is desired to have additional entries, these may be added manually. This is used to mitigate Header Post Poisoning attacks.
