RE: ORA-07445

Shuan,  

Can't tell you what exactly to do, we will need more detailed information than just two ORA codes.
Your database can't read one of your data file and that could be because of many things.  

Your database is in NOARCHIVELOG mode, and this means that you have no protection against
media failure such as lose of a disk that has your data file on it. You should read the Oracle
Administrator's Guide on what is ARCHIVELOG mode and how to switch to ARCHIVELOG mode.  

Regards,  

Richard Ji
