By the way, does any one know how to verify the directio on solaris ufs
via filesystemio_options?



If we enable forcedirectio with mount option, we can verify it via
mount command.


But How to veriify it if we enable it at oracle level, via the
filesystemio_options?



I tried pfile/truuss, can't find it is using o_direct option. But with
and without directio option, I do see BIG performance while I was doing
import test.



Thanks
