We have an oracle Database on AIX box. We want to delete the database safely.
How can scrubb the datafile prior to delete on AIX?
Do you mean you need to erase the file - scrub the disk sectors of the file so disk scrounging cannot happen?
diag -T "format" command used to do that, I believe.
Also for a better tool try this from security paranoia central:

I worked there for several years, and so can attest to the paranoia.
