> AFAIK, there's no way to turn caching completely off in Linux. It is my understanding that any file that is opened with the O_DIRECT option bypasses the Linux cache. I believe that this support was added in SP2 to SLES8.
I know that Oracle 10g will open its files with this option if the init.ora has the parameter filesystemio_options=directIO. From the tests I have done, this support works. I do not know what other applications implement the O_DIRECT option on FOPEN, but it seems to me that bypassing the Linux cache is up to the application. Tom Russell "Stay calm. Be brave.
