concurrency used by NSR-ORA when backing up tablespaces is one
less than the concurrency of NetWorker when nsrora_save_cmd is not
used, because NSR-ORA always uses one backup for internal purposes.

The database must not be started up while an offline backup is in
progress. Under ORACLE Parallel Server (OPS), the instance which is
carrying out the backup is given exclusive access to the database; this
also prevents the database from being started up by any other instance.
In other cases you will receive an error message at the end of the backup
if the database was started up in the meantime.

If you want to back up a database which is currently online under OPS,
while the instance that is to be used for the backup is offline, that instance
will be started and an online backup will be carried out instead.
