permission

the information you give is incomplete,

there are file systemlevel permissions inthe unix world .
so to create a directory for example:here dpump
to make it simple :

the user ,who is loggied in should have permissions to write to the filessytem. in secure way .with users rights ,group rights , there is some thing called as others rights .

here , it seems you are configuring the dpump dir and grant access level privilages to scott user on that directory ,

you need not create one

there is a default directory .

"PS: Oracle introduced a default directory from 10g R2, called DATA_PUMP_DIR, that can be used:
SQL> SELECT directory_path FROM dba_directories WHERE directory_name = 'DATA_PUMP_DIR';
"

case 2) if you dont want to use the default directory ,still want to create the directory

 dpump

from
the prompt:

#[oracle@new backup]$ su root
give root password
make directory here
#mkdir dpump
#chmod 777 dpump --later you canreset the permissions,

and gothe procedure .
