We’ve now received a response to the issue described in the previous entry. In short oui updates at install time are broken (apparently fixed in 22.214.171.124, but no updates are available for that release yet to check.
The OUI looks for the metadata for the patches.
There is an unpublished bug 11709996 on 126.96.36.199 due to which ,the latest patches are not being downloaded.
Hence We’ll recommend you to check for the latest patches from My Oracle Support and apply the latest patch manually using opatch.
It would be interesting to know if the same issue affects Enterprise Manager patch recommendations as well (one would like to think that Oracle only have one “check for latest updates” routine, but you never know).
