Installation d' Oracle 9i sous Red Hat AS3

salut !
Lorsque je lance l'install à partir du cdrom Oracle9i, j'obtiens les erreurs suivantes :

[oracle@TTISBDD01T cdrom]$ Initializing Java Virtual Machine from /tmp/OraInstall2005-06-14_06-00-42PM/jre/bin/java. Please wait...

grep: /lib/jvm.cfg: No such file or directory
java was not found in /bin/i386/native_threads/java

Apparemment il y a une incompatibilité entre mon serveur qui est une machine ia64 et oracle qui veut installer sur une machine i386. Comment puis-je y remédier ??

Merci d'avance !!

Configuration: Red Hat Enterprise AS 3 sur une machine ia64
