I am handling a 700GB Apps 11.5.10 database running on HP-UX PARi(went live last week). The performance is quite poor, I noticed that filesystemio_options by default is asynch. AFAIK there are three options, asynch, direct and setall, should this set to none if AIO and directio arent used?
I guess it has to use asynch (even though AIO is not supported in HPUX if raw device is not used) since direct i/o is not enabled. I deduced this because in fstab thse options are not used
My experience in hpux is limited, worked with Solaris most of times. Does anyone know if enabling these options in Veritas JFS will make lot of difference? After enabling that do I have to set filesystemio_options to directio?
