Yesterday, There was a STORAGE ABNORMAL SHUTDOWN HAPPENED. after STORAGE WAS restored.
The Oracle Database is crashing down in few minutes as soon as we start the Database.
Hi,
In this case we can do one thing. creating new undo tablespace as below.
create the tablespace with this SQL
create undo tablespace undotbs2 datafile ‘/u02/oracle/oradata/test/undotbs2.dbf’ size 500m;
Alter the database to use the new UNDO tablespace.
alter system set undo_tablespace=undotbs2 scope=both;
Then take the original UNDO tablespace offline
alter tablespace undotbs1 offline;
Next drop the corrupted segment.
drop rollback segment <corrupted segment>;
Then finally drop the old UNDO tablespace
alter tablespace undotbs1 offline;
Regards,
Venkata S Pagolu.

It seems like your undo tablespace is corrupted. You need a backup to get it working again on your own.
Maybe Oracle itself is able to fix that corruption, but you need to open a SR for that.
