A couple of interesting comments were posted to this thread, the first from Tom Mercadante who said
"Here's the best part. Oracle now has *two ways* of sending patches out to
us. One is the current (old) way where you run oracle installer. The other
(new) way is where you run Opatch. And even within Opatch, they do things
two different ways. Security Patch 68 has you run sqlplus and install new
packages, and then run patch.csh - which runs sqlplus and installs stuff."
"Seems like the bad old days are
reappearing - where the divisions are not talking to each other anymore, and
they release stuff that is not ready for prime time"
The second interesting comment was from Paul Drake who said
"use opatch 22.214.171.124.51, not 126.96.36.199.50.
I find myself checking the notes on Metalink on a daily basis for this one.
if you're running on win32 - the files under the "docs" folders are invaluable."
Good advice seems to be to review the Alert 68 FAQ regularly if you have still not applied the patches or are still in the process of doing so.
