Our Oracle DBA wants to know if Asychronous
I/O is enabled on our Solaris 2.6 Sun E6500.
We are running Oracle DB v8.0.6 and v9.0.1,
and he needs to know this in order to
properly tune the database(s).
What is asynch I/O exactly? How to enable it
and verify that it's been enabled and in use?
Can it be used with mounted filesystems
(UFS)? Any gotcha's or limitations with using
or not using AIO? What is KIO, and how does
it relate to AIO (if at all)?
Any help would be appreciated.
Thanks,
SCB
