I am really at a loss. I have been on this problem for almost a week now.

Primary switches over fine.

On Standby I issue the command: alter database commit to switchover to primary with session shutdown

I am getting this error:

ERROR at line 1:
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: 'E:\ORACLE\ORADATA\CESCATI\SYSTEM01.DBF'

I have checked and rechecked the path and existence of these files that are located on the former primary server. They exists! Are they not being found? or Why would they be locked? The former primary is already converted and mounted as standby.

Here is my DBWR trc File content:

I had the path values switched around to:

db_file_name_convert='\oracle\oradata\cescati','\oracle\oradata\cescati2\standby'
log_file_name_convert='\oracle\oradata\cescati\archive','\oracle\oradata\cescati2\standby'

I dont know what to do next. Does anyone have a clue what I am missing here?
