Hi,

This looks like a password problem (setDbUserPassword):

You may have entered an incorrect password for the OS or SYS; or saved incorrect OS or SYS passwords as your Preferred Credentials. Try to reenter your OS and SYS credentials and try stating the database again.

As a last resort, you may also want to reconfigure DBControl for your database by running emca (in ORACLE_HOME/bin).

Best regards.

Frank

Hi Frank,
Thanks a lot for your response.I extremely appreciate this you were the only one who replied after so many postings.I couldn't fix the problem through password or emca.However, I got this message below whilst I scheduled a backup through ENTERPRISE MANAGER.
OUTPUT LOG:The process cannot access the file because it is being used by another process.
Unable to perform the backup because the database status cannot be determined.
Do you have any suggestions about what I should do to fix this?
I am at a loss as to where to start to troubleshoot this error.
Thanks for your time.

Hi,

I wouldn't know where to start myself. Maybe try to download FILEMON (freeware utility) from http://www.sysinternals.com/ and see if you can identify the blocking processes.

Best regards.
