Copying my Oracle 10g Express database to another PC I have Oracle 10g Express. How can I make a copy of my database and application?

I don't want to make a back up, I want to move my DB and application to another PC.
First Install XE to another PC.

Then clone your database: Backing Up and Restoring the Database

Then transfer clone to another PC and restore the clone there.
