Ethan - it has been a while and we don't have an HP-UX box here, but if memory serves the missing /dev/async is a dead giveaway that your not using async io.
to use async io on HP-UX we had to install something called the asyncdisk driver in SAM and then use mknod to create /dev/async directory. could the asyncdisk driver already be installed and you just need the directory? SAM should tell you. if not i think it means a kernel rebuild. -----Original Message----- Sent: Thursday, March 13, 2003 10:44 AM To: Multiple recipients of list ORACLE-L /dev does not have an async directory, async IO is turned on in the database, how do I determine if async IO is activated on the OS side of the house? Is the missing async directory an indicator? Also, is the database smart enough to figure out that the OS is not using async and make correct call or will I get a timeout on async call then perform standard write?
