Question : ORA01122

A database intensive operation failed during execution and then after a reboot of the system
 when I try to log on to oracle it gives me these error messages

it is on Win NT and Oracle 8.0.5
 
ORA-01122: datafile name - failed verification check

Cause: The information in the datafile is inconsistent with information from the control file. This could be for any of the following reasons:

          The control file is from a time earlier than the datafiles.
          The datafile size does not match the size specified in the control file.
          The datafile is corrupted.

Action: Make certain that the datafiles and control files are the correct files for this database, then retry the operation.

 

ORA-01200: actual file size of num is smaller than correct size of num blocks

Cause: The size of the file, as returned by the operating system, is smaller than the size of the file as indicated in the file header and the control file. Somehow the file
has been truncated.

Action: Restore a good copy of the datafile from a backup and perform recovery as needed.


any help will be greatly appreciated.

best regards,

Pinto.

Answer : ORA01122

Hi again
I don't think that as you wrote:
"A database intensive operation failed during execution and then after a reboot of the system

is the problem, unless you did a shutdown abort or turned the server off while the database was doing rollback.

Maybe there is a little hardware failure or something???
Have you checked your alertlog lately?
