[SOLVED]CodeIgniter and Oracle 11

[eluser]Mareshal[/eluser]
trying to make CI play with Oracle...but

Code:

$db['default']['hostname'] = "//localhost:1521/oracleServer"; //SID is oracleServer, not XE, so is correct
$db['default']['username'] = "SYSTEM";
$db['default']['password'] = "oracle";
$db['default']['database'] = "TEST";
$db['default']['dbdriver'] = "oci8";

These settings work from SQL Plus or SQL Developer, user SYSTEM is ok, but is CI 2.0 I get

Code:

A Database Error Occurred

Unable to connect to your database server using the provided settings.

Code:

$db['default']['hostname'] = '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=oracleServer)))';

Solution found!
