Hi all,

I need to clone database A to database B.
I don't have enough space for undo datafiles in server for database B.
Can I create directly undo tablespace and datafiles on database B ? How ?

Thanks for your help.

If the undo datafile is created with an initial size and autoextend on.
Will the size of the datafile always return to initial size whenever we shutdown the database ?
Even if at a certain time the datafile exceed the initial size ?

Thanks
