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.

!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.
