[otrs] Installation on Oracle 9.2

Hi, I am trying to install OTRS 2.1 for my client under Oracle 9.2. The problem comes with the initial insert script. All the insert statements are based on the "AUTO_INCREMENT" status of the tables. But this doesn't exist in Oracle. I found one mail in the mailing list archives about someone writing a patch. My question is, is there someone who allready wrote a patch for these insert (and maybe also for the rest of the code?) Second question, do you recommand using Oracle anyway? Thank you for your answer Regards, Bastien Leblanc - Peoplesoft Administrator CAPGEMINI
