## Provider's notes

## For Oracle

The following arguments are used to connect to an Oracle database:

Table 1.

Argument name | Description | Required
--- | --- | ---
DB_NAME | Service name: global database name entered during database creation (it combines a database name with a domain name), can be left empty to connect to the default database. | No
HOST | Database server: host on which the database server is running | Yes
PORT | Port: database server port (leave this field empty for the default 1521 port) | No

Note however all the arguments above can be replaced by a single TNSNAME argument (see the "Oracle Database Net Services Administrator's Guide" for more information about defining connection identifiers).

Also refer to the Oracle's provider's limitations.
