> redo logs are always wrote using O_DIRECT parameters




Where do you see O_DIRECT? And you only see that for redo logfiles, not
datafiles? O_DIRECT is a flag you set for open(2) system call on
certain OSes, such as Linux and SGI. Oracle's OCFS also allows this
flag to be set and its semantics is a little different.
