Explanation and solution are documented in MOS Doc 1309467.1, assuming you care to read the document, understand the explanation/instructions, and implement the solution
How does Oracle being the file owner stop any user with delete permissions at the directory level from removing the file? It just means you get a prompt asking if you really want to remove the file so in batch you would have to add the force option. Normally that is rm -f but may vary by platform. Check the man page. Another alternate might just be to use chown to change the owner.

I thank you all,
So what will be the right ownership and permission for the EXPDP folder "/u07/dpdump" ? Is it "oracle:batch" or "batchuser:dba" ?
