DBWR, LGWR error in ORACLE 8.0.3.0.6 on Novell 5.0

Hi all,

   I am working on ORACLE 8.0.3.0.6 on Novell 5.0. Presently  iam facing the serious problem that when iam doing oraload  and then orastart instead of starting up the oracle database  it is showing the error
   oracle database connected.
   ora-00449 -- Background process DBWR, unexpectedly terminated

                with error ora-01092

   when i checked the orclDBWR.trc ( my oracle sid is ORCL ) i  found that it is showing.
