   Hi!



   We use Oracle 8 (8.0.6.2.0) and HP-UX 11. All our Oracle fs vxfs
file systems.



   I discovered using the tusc utility that HP-UX is doing 8K reads on
datafiles, regardless the Oracle db_file_multiblock_read_count
parameter, which is tuned to do 256K reads.



   We read that we must use the direct_io options of vxfs, mounting it
with the parameter convosync=direct



   Well, we did everything right but the reads are still been done in
8K chunks.



   Any hint or help is welcome!
