I’m getting the following error on starting Oracle database through the enterprise manager console :
ORA-01122 : database file 2 failed verification check
ORA-01110 : datafile 2 ‘D:\oracle\oradata\new1\undotbs01.dbf’
ORA-01200 : actual file size of 72733 is smaller than correct size of 72960 blocks.
The database mounts but is not able to open. I don’t have any backup of the database nor the datafiles.
