Re: AIX 5.2 Or AIX 5.1 for Oracle 9.2 database server?

Did you get any replies off-list? We are moving to Aix so I'm very 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.
