Thanks for that, I'll have a look at it.
I got a reply from Oracle Support, after escalating the SR, and they give similar steps, except they didn't mention catpatch.
I did catch that, and am awaiting an answer on how and when catpatch should be run. I believe catpatch should be run with the database started up in migrate mode? In which case I believe all nodes should be shutdown, though I may well be wrong.
But thanks again, I'll have a look.
