Problem exists between keyboard and chair.
You refuse to read documentation and you refuse to ask questions with specific error messages.
I recommend you hire someone who will read the documentation on your behalf, and who can ask a proper question.
Export BTW is NOT a backup!!!!
Senior Oracle DBA
i am using Oracle 10G Enterprise Edition (10.2.0.1.0) on Red Hat Linux 32bits OS. I made backup file (.dmp) through exp command (not expdp) on the said Linux platform. When I tried to restore that dump file (.dmp) to Oracle 10G Xpress Edition on Windows 7 platform, this won't work. Is there any solution...??? Is there any character encoding problem???
I don't find "won't work" in any error message manual.
Oracle emits actual error messages with code number for a reason.
If you had shown us said error message, perhaps we could provide some help.
