Hi,
a nice document for Oracle on Aix is the next one:
http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP100883
It gives a short, but practical guide how to setup Oracle on Aix

Onderwerp: Filesystem blocksize for archive logs on AIX
Hey all,
I'm configuring new 11.2.0.3 DBs on a new AIX 7.1 box. Instead of cloning
our current setup on AIX 5.3, I'm revisiting all options for both
flexibility and performance.
The docs
(http://docs.oracle.com/cd/E11882_01/server.112/e10839/appa_aix.htm) and MOS
articles like 1507249.1 are great, but one item I can't find anywhere is a
recommendation for a filesystem blocksize for the archive logs. 4K for
datafiles, 512 for online redos and controlfile, but nothing for archives.
512 would seem to be the likely answer, but it's been too many years since
my v7.3 DBA classes and I can't remember how the archiver does its IO
(sorry, Joe!). The docs don't seem to have that answer, either.
I'm also open to any other advice for AIX-specific setup that's not
referenced in the above docs (e.g. JFS2 noatime/rbrw for $ORACLE_HOME?). If
it makes a difference, we'll be using XIV for storage. Seriously looking
forward to playing with that puppy... :D
TIA!
Rich
