Connect to tunneled oracle database

[eluser]sojic[/eluser]
There is remote oracle database. The client should "tunnel" and "map" the database port to localhost.... so... with Navicat I can connect to oracle database with

Host: localhost
port: 1521
user and password


I try to set codeigniter to user oci8 driver... but it do not work... also get error:

Severity: Notice

Message: Use of undefined constant OCI_COMMIT_ON_SUCCESS - assumed 'OCI_COMMIT_ON_SUCCESS'

Filename: database/DB.php

Line Number: 133

Any help how can I connect to the oracle on "localhost" port 1521
