Hi,



Altough i have set filesystemio_options=setall and mount the file
system by using forcedirectio , truss output of oracle processes shows
that files are opened by using o_dsync:



 open("/data/oradata/spssdata01.dbf", O_RDWR|O_DSYNC) = 13




How can i be sure that direct io is in use? Why does not open call use
O_DIRECT flag?



Kind Regards,


hope
