I used the graphical UpdateManager window to successfully install patch 118822-08. All the actions were clicked on.
I might prefer to use the command line approach since my host is very underpowered as a 256MB Ultra-10 PC.
The results of the diagnostic OS kernel message correlates. The "showrev -p" shows the patch at level 08. The graphical output shows it in the installed patches.
I loaded this patch just for kicks. I noticed that the patch said that it was withdrawn when I looked at it yesterday. I was browsing it and I tried to download the patch using the sun support site.
