Frightening number of linking errors for 11.2.0.1.3 on AIX 5.3 TL11

I just applied PSU 3 for 11.2.0.1 on AIX 5.3 TL11. That would have been more straight forward, had  there not been a host of errors when relinking oracle. There were loads of these:

SEVERE:OPatch invoked as follows: 'apply '

Wow, that looked like a completely corrupted installation of Oracle now, and I got ready to roll the change back. However, MOS had an answer to this!

These errors can be ignored as per this MOS document: Relinking causes many warning on AIX [ID 1189533.1]. See also MOS note Note 245372.1 TOC overflow Warning Can Safely Be Ignored and BUG:9828407 – TOO MANY WARNING MESSAGES WHEN INSTALLING ORACLE 11.2 for more information.
