Hi All, I am getting the following errors when I am trying to open my database. There was a power failure to the server over the weekend, that caused me all of this messs. Here are the errrors: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ORA-01122: database file 2 failed verification check ORA-01110: data file 2: 'C:\ORACLE\ORADATA\TRACS3\UNDOTBS01.DBF' ORA-01200: actual file size of 83976 is smaller than correct size of 138240 blocks - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Does anybody have any ideas on how to get my db started back? The last known good back up is about a month-and-a-half old. All other datafiles seem to be ok. I would really appreciate any help on getting my database up. -- Regards, Srinivas Chintamani
