I once saw a problem like this on an AIX box. The SA was doing full
backups with the Oracle instance up but no users logged on. One
controlfile would go out of synch. Not sure if that's helpful to you.

Subject: ORA-214 on VCS Failover

Please
respond to
ORACLE-L
During Veritas Cluster Failover (Solaris8, Oracle9i, EMC) testing we
encountered the following scenario...and it has me stumped!
Database failed over to secondary server...operates without error database
up and running
Database failed back to primary server...ORA-214 signalled during ALTER
DATABASE MOUNT
This indicates that we have a file that is out of sync (as if we had
restored an old version and not done a recovery).
In looking at the database files, our 3rd control file had a time stamp
from the first failover, where all the other active files (excepting
inactive redo logs) had a timestamp from the second failover. Residing on
the same disk as the out of sync control file was the file to the users
tablespace (users01.dbf) that had a timestamp of the second failover. Once
we replaced the bad controlfile with a good one, the database could be
mounted and opened.
So, if Oracle could not read all of the control files, why did it even
update the first one? If it could not read all 3 controlfiles, why were
the individual database files touched?
My understanding of the startup stages don't offer any explanation for
this behaviour. Perhaps it is an Oracle bug...
