Recap on Deinstall Routines
By Mike Dietrich-Oracle on Nov 15, 2010
A few weeks ago I'Ve posted something about the deinstall utility as OUI doesn't offer a "deinstall software" option anymore:
How to deinstall "old" SW after 184.108.40.206 has been applied?
And I've got some feedback (which is a good sign as it means that some of the content might be useful and will be read - and from the follow-up you see that we'll read your comments and emails as well :-) ).
Anyway, the feedback was either CRS deinstall does not work the right way or deinstall cleans up too many things. So Roy did follow up with our (very helpful and fast-responding) installer colleagues (Thanks a lot, Matt, Sudheendra & Anesh!!!) - and that's their response:
Per documentation http://download.oracle.com/docs/cd/E11882_01/install.112/e17212/procstop.htm#CEGGHAFG users are supposed to do the following :
1. #chmod -R 755 oldGH (GH stands for 'Grid Home')
2. #chown -R swowner oldGH
3. #chown swowner oldGHParent
There is step #4, which is to use "220.127.116.11 standalone deinstall tool" (MyOracleSupport 18.104.22.168 patch set download!!!) to remove 'old' (or 22.214.171.124) Grid home. This step is missing right now and I have asked the doc folks to update it.
Also, this will be fixed in 126.96.36.199 and later (this issue is tracked by bug 9924588).
