This works well, as I've used them with Oracle databases. The only problems I've encountered is that the device-special files' ownership is re-assigned to root when the system is rebooted. I added an rc script to chown them back to oracle. One thing that surprised me is vxva's notion of a Megabyte, which Oracle and other programs often interpret as 1024x1024. Apparently vxva considers a Megabyte as 1024x1000. So, a 64M Oracle file won't fit into a 64M raw partition. Easily corrected if I used bytes instead of Mbytes when creating either structures. -- Mike J Oropeza ---------------------------------- Those who hear not the music - think the dancers mad ~{';'}~
