Since seems like copy files across 2 directory (1 mounted and 1 not) doesn't work (I've tried using UTL_FILE.FRENAME, asking here and also on asktom but no one actually could help me)
I've decided to use a workaround:
COPY then DELETE, in terms of exception, what problems could merge? Is this a safe operation, I mean a solid-rock solution? (UTL_FILE.FCOPY then UTL_FILE.FREMOVE)
Or it's better to do behind some bash scripting like mv
Thanks
