It seems to us that there's actually nothing wrong with Oracle (8i and 9iR2) on AIX 5.1. This of course doesn't mean that there are no problems... We have some 80 other AIX machines (various versions) for various purposes. Of those ~80, about 20 are used for Oracle DBs. LVM is used on all of them :-)
