interested in this topic.
Thanks

Hi, friends:
There is a project that migrate a 9.0.1.3 database on linux server
to
9.2.0.3 on aix/p670 server, and I have some question about this
project,
hope friends in the list can share your idears.
1.Shall I use AIX 5.1 or AIX 5.2?
According to pagev
http://www-1.ibm.com/servers/aix/os/52features.html, the most
attractive of
5.2 is the jfs2 and large page support,cpu-guard and virtual IP
Address. But
not sure whether Oracle 9.2 will support large page or not(9.2 on linux
does
support large page of 2MB).Multipath IO is also avaliable for aix5.2.
But 5.2 is even newer than 5.1 and I am not sure whether it is
stable or not? Does anyone here have experience running 9.2 on aix 5.2?
What
is the current ML level? Do I need to apply any special patch for
database
to intall and run smoothly?
2.If using AIX 5.2, we should use 64bit kernel, and according to
document, by default it will use jfs2.In jfs2, there is a feature
called
concurrent IO.Concurrent IO provide much better performance while it is
a
rather new feature, shall we use it for better performance? Have anyone
used
it?
3.If using multipathing, will the same disk be recognized by aix
as
different hdiskN? If yes,How do i solve this problem?
Thanks.
