System: 2 CPU ES40 with Tru64 5.1A+pk1
Ever since we moved to Tru64 5.1A from 5.1, users have been
complaining that Oracle is quite slow on our system. My Oracle
DBA says that direct I/O that is implicitly enabled in AdvFS on
Tru64 5.1A affects Oracle's performance considerably.
Is this true?
My reading up of the AdvFS Administration manual tells me that
one must request direct I/O explicitly when the file is opened.
So, it begs the question: is direct I/O implicit for all AdvFS
files or is Oracle asking for it in their code?
If so, how can one get around this problem? Moving to 8.1.7 is
not possible at the moment as SCT, the supplier of BANNER, has
not yet approved its usage.
Any help will be greatly appreciated.
Thanks in advance,
