Hi, All I am trying to use data pump to export the whole database (db version 10.1.0.4). Here is what I have done: 1. login sys as sysdba and created the directory as follows: create directory dumpdir as 'D:\dbback\orcl\export'; grant read, write on directory dumpdir to system; 2. run expdp as follows: expdp system/password full=y directory=dumpdir dumpfile=full_exp.dmp job_name=full_exp logfile=full_exp.log then expdp just hang up, log is as follows: Export: Release 10.1.0.4.0 - Production on Friday, 17 March, 2006 16:14 Copyright (c) 2003, Oracle.
