Problem during restoring from command prompt :

In above case, You can see the error message `role “john” does not exist`. It means that database has been backed up from another PC having name is ‘john’.

So now, in this case there are two solutions to restore this database as follows.

1) Either you can open dump file, and change the role name wherever you find name ‘john’ as your role displayed in following screen. Here I have changed name as ‘navrang’ in place of ‘john’.
