Oracle crashes with following error message. It is a Windows 2000 server. We just installed Oracle in this server and created 1 database and OEMREP database. No other activity on this database. We are running Oracle 188.8.131.52.0
Errors in file d:\oracle\admin\oemrep\bdump\oemrep_lgwr_1964.trc:
ORA-00345: redo log write error block 106927 count 1
ORA-00312: online log 1 thread 1: 'D:\ORACLE\ORADATA\OEMREP\REDO01.LOG'

OSD-04008: WriteFile() failure, unable to write to file
O/S-Error: (OS 33) The process cannot access the file because another process has locked a portion of the file.
We have ensured that there are no backup process or virus scan are running in this machine. We can not think of any process which will lock this file. Any help on this is greatly appreciated.
Sounds suspiciously like either a backup process or some other OS utility (like a defrag or something) which has been scheduled to run during the night. Check what jobs are set to run at night on your server.
Also are there any other servers which have access to the disks on your server?
