Well, Oracle 11g for Linux x86-64 was available, well at least for a day! I did try and download on 12th October but the Oracle content management system was obviously screwed as all I got was an error page. One day later and the release is pulled altogether from the site. C’mon Oracle get yer act together, I do hope this inability of the right hand knowing what the left is doing is not indicative of the quality of the release!
That being said I suspect I might wait until the first patchset before upgrading my production boxes, I remember all to vividly the pain of installing Oracle 10.1.0.2 on Solaris Sparc.
