Export Oracle tables based on owner + all users from database I would like to export all user and roles objects from Oracle 10g database to another.
I googled it but I cannot find out how to do it.

First I use this command:


  exp system/root@[DB_Name] file=[Back_file_name] owner=([Owner_Name])


But the problem was that some table settings depend on user privileges. Hence I want to also export user objects.

For example it is possible to export all objects with this command:


  exp system/root@[DB_Name] Full=Y file=[Back_file_name]


But this command does not export the needed objects for me.

I would like to export only:


tables by owner name
all users 
maybe roles


Is this possible?
Data Pump export/import is what you're looking for. You can use this to export your schema definitions and load them into the target database, specifying which type of objects you require.

You can select specific types of objects using the INCLUDE parameter, so to just export tables you would:

expdp include=table ...


Provided you run the export/import as a user with sufficient privileges, this will also create the users on the target when you import.
