Forum OpenACS Q&A: Response to How to upgrade Oracle from 126.96.36.199 to 188.8.131.52 ?
You can download the newer patchset directly from metalink.oracle.com, but while possible, it is exceedingly annoying to use wget to do so. E.g., for the 184.108.40.206 for 32 bit Solaris patchset, try:
$ wget -b --http-user=MY_METALINK_USERNAME --http-passwd=PASSWORD 'http://ap103aru.us.oracle.com/ARULink/PatchSearch/process_download/p2376472_8174_SOLARIS.zip?patch_file=p2376472_8174_SOLARIS.zip&aru=1697372'
But there's a better way. Once you use their god-awful patch search tool to figure out the patchset number you need (# 2376472 for 220.127.116.11), ftp them from updates.oracle.com, using your Metalink username/password to log in. E.g., here are links to some of the 18.104.22.168 patchsets: Linux, Solaris 32 bit, Solaris 64 bit.
