Won't be today, as mentioned. There doesn't seem to be a significant regression for Oracle on 4.x. I've spent 4 hours on this this evening and the installer *still* doesn't work properly on 4.x, with or without an "equivalent" patch to linprocfs_misc.c. This isn't new with the linux8 patch, and it's widely believed that RELENG_5 or greater is a basic requirement for Oracle to work under linux emulation (for 9i at least - I don't have earlier versions to hand - marcel wrote the handbook section on this and may be able to test Oracle 8.x). Ceri --=20 Only two things are infinite, the universe and human stupidity, and I'm not sure about the former. -- Einstein (attrib.) --NP12RPW2Q08TId7w Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFB3cPDocfcwTS3JF8RAnxSAJ9JhGxGCy+0/loI08YICP2qXCtQ1QCfXKZL T7F0MVnW5TmL5hl+fYNGd0M= =oHas -----END PGP SIGNATURE----- --NP12RPW2Q08TId7w--
