Ok, this is extremely irritating. I opened an SR yesterday on installing GI PSU2 (patch 9655006). I was getting the error message below. I did a lot searching, and according to what I could find on MOS and the internet, I need to manually install the patch, instructions for which are available on note 1210964.1. This note is unpublished, so MOS has to give me access to the note. So far, it appears that MOS has yet to even read the SR, despite my follow up phone call today. So, can someone here send me the contents of that note? I did find a set of instructions for manual patch installation on a blog, but I generally prefer some confirmation before using that sort of information.
