Check undo_tablespace parameter:

SQL> show parameter undo_tablespace

NAME TYPE VALUE
------------------------------------ 
undo_tablespace string UNDOTBS1

Try to recover it:

SQL> recover datafile 3;

Media recovery complete.

But can't solve it:

So, Create New UNDO TABLESPACE:

SQL> CREATE UNDO TABLESPACE "UNDOTBS2" 

DATAFILE'/oradata/db2/undotbs02.dbf' SIZE 100M AUTOEXTEND 

ON NEXT 10M MAXSIZE UNLIMITED RETENTION NOGUARANTEE;

Tablespace created.

SQL> alter system set undo_tablespace=UNDOTBS2 ;

System altered.


SQL> shutdown immediate ;

ORA-01110: data file 3: '/oradata/db2/undotbs01.dbf'


But can not shutdown:
