ORA-01203: Wrong Incarnation Of This File – Wrong Creation SCN
PROBLEM:
While opening a database, getting the error, ORA-01203: wrong incarnation of this file.SOLUTION:
To fix this, either you have to restore that datafile from latest backup or drop the datafile if it doesn’t contain any valuable data.
In my case, the issue was with undo datafile, so I dropped the same.
SQL> alter database datafile '+DATA /WMBPRE/undotbs201.dbf' offline drop; Database altered. SQL> alter database open; Database altered.
