Thanks everybody,

After I have backed up all the tablespaces I issue an ' alter database backup controlfile to trace'

I then recreate the controlfile using the SQL.

I have to do it this way as the database name and file structure names change slightly.

Mike the idea that it might already be in backup mode could be a good one. We do get alarms if our tablespace our left in Backup mode but this now seems the only logical explanation.

Updates/Writes to the file during the O/S copy process, possibly, makes = the copied file inconsistent.

Why OS copy of control file won't work?

Guang,
Under normal circumstances yes, but the control file has to be a "alter database backup controlfile . . .", not a OS copy.

I am trying to understand:

Is it true that if the copy of control file (just an OS copy) is done = AFTER issuing

ALTER SYSTEM ARCHIVE LOG CURRENT; then no earlier (than the log switch) archive log is needed? We still = need the archive logs generated during tablespace backup process.
