FYI for 126.96.36.199.2 patchset update ... ( noted in 1291879.1 ).
So this patchset update has just rolled out and they are already
recommending a patch on top of the patchset update. As far as I know
the patchset updates are supposed to have already been subjected to
rigorous and extensive QA testing and verification ...
1.1 Patch 12431716 Is a Recommended Patch for 188.8.131.52.2
Patch Patch 12431716 is a recommended patch for Database PSU
184.108.40.206.2 installations and Oracle strongly recommends that the patch
be installed. The readme for the PSU 220.127.116.11.2 Patch 11724916 has
also been updated to indicate the same.
