migrate_example_oracle.migrate.inc in Migrate 6.2

Examples and test fodder for migration from Oracle sources. To use this example (and to run the corresponding tests) you must define a connection to an Oracle database in your settings.php. E.g.,

$conf['oracle_db'] = array( 'username' => 'DRUPAL', 'password' => 'DRUPAL', 'connection_string' => '//oracledb/orcl', );

The username must have the CREATE TABLE privilege, so test data can be stored for the example to import.

See http://us.php.net/manual/en/function.oci-connect.php for more information on connection_string.
