To add to Mladen's already very good reply, consider the following:

  • P7 is a new architecture for Aix that is fully supported by Aix only on release 7.1 onward.
  • 10gr2EE is *not* certified for Aix 7.1 - and it actually needs a patch to run correctly in 6.1.

I'd consider upgrading to 11gr2(SE/EE) as that has full support for Aix 7.1 and hence for P7. Received on Sun Jan 29 2012 - 19:38:08 CST
