Yes,.. when you do the cp --o_direct ../a2/control02.ctl ./control01.ctl
can you run an md5sum on both files?

ie run the command
md5sum ./a2/control02.ctl ./control01.ctl

*IF* the md5sums match then we can be sure that the file indeed was
copied over correctly and that the original ./a2/control02.ctl file was
already corrupted.. (that or theres another file that is supposed to go
along with it, I don't do much oracle db work myself)
If the md5sums do NOT match then it's a cp issue and I need more
beatings. If thats the case can you give me an ls -l listng of the two
files (it'll give me an idea as to if there is a short write going on)
