[TYPO3] Typo3 with Oracle

[Jan.Albrecht at bertelsmann.de]

Hi all,
 
since a few days I'm trying to connect to Oracle with typo3.
I've searched google and found a few how-to, but it still doesn't work.
The manual installer still says that it can't connect to the database.
 
I've build PHP with pdo_oci and when I'm using native PHP functions I
can connect to the databe. But I can't manage to connect typo3 with DBAL
and ADODB.
 
Has anyone of you successfully connected typo3 to Oracle?
 
Thanks
Jan
