I know i can turn asynch io off in the database by setting<BR />disk_asynch_io=false and filesystemio_options=none. <BR /><BR />But if the system supports asych io , then maybe i should attempt to find out why i'm getting the errors in the trace files?<BR /><BR /> Sun, 18 Jul 2010 02:08:49 GMT https://community.hpe.com/t5/operating-system-hp-ux/asynchronous-i-o-to-disk/m-p/4662715#M615575 Donald Thaler 2010-07-18T02:08:49Z https://community.hpe.com/t5/operating-system-hp-ux/asynchronous-i-o-to-disk/m-p/4662716#M615576 hi,<BR /><BR />check this articles :<BR /><BR /><A href="http://forums.oracle.com/forums/thread.jspa?threadID=877341" target="_blank">http://forums.oracle.com/forums/thread.jspa?threadID=877341</A><BR /><BR /><A href="http://ericwijaya.wordpress.com/2009/11/06/warningcould-not-set-the-asynch-io-limit-to-64-for-sql-direct-io-it-is-set-to-0/" target="_blank">http://ericwijaya.wordpress.com/2009/11/06/warningcould-not-set-the-asynch-io-limit-to-64-for-sql-direct-io-it-is-set-to-0/</A><BR /><BR />mikap Mon, 19 Jul 2010 04:21:49 GMT https://community.hpe.com/t5/operating-system-hp-ux/asynchronous-i-o-to-disk/m-p/4662716#M615576 Michal Kapalka (mikap) 2010-07-19T04:21:49Z
