We must enable it explictly with _filesystemio_options=asynch. Is it true? For aio on raw device/QuickIO, we can see truss -t kaio -p dbwr to verify it, for aio on filesystem, how to verify it then? And other question about solaris, that doc also says, with solaris 8 update 3, there is concurrent directIO for ufs. Is it a feature of ufs, or a feature of solaris kernel? If it is a ufs feature, then even with solaris 8 update 3, I cannot use this feature on vxfs/solaris8 update 3.If it is a feature of solaris kernel, I think CDIO is also ok on vxfs, is it true? And how can I know whether my solaris 8 is using update 3+ via command line like compare the kernel version (uname -a)? Thanks. zhu chao. ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@freelists.org put 'unsubscribe' in the subject line. -- Archives are at http://www.freelists.org/archives/oracle-l/ FAQ is at http://www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
