Oracle Server side - common error ?

It seens to be a lot of posts around this but i wasn't able to find a proper solution for this.

Using the default script provided, when i try to execute the php_oracle.php ( content of the file is : http://www.datatables.net/development/server-side/php_oracle )

I receive de rerror:

Im new to php and datatables, so it would be great to have a practical example =)
