Oracle Tips by Burleson

Oracle 10g RMAN Changes to the ALTER DATABASE END BACKUP command

You can run the ALTER DATABASE END BACKUP command when you have multiple tablespaces still in backup mode.  You can issue the statement to take all data files currently in backup mode out of backup mode.  However, you can use this statement only when the database is mounted, and not open in Oracle9i.  If the database is open, you can only use ALTER TABLESPACE ... END BACKUP or ALTER DATABASE DATAFILE ... END BACKUP for each affected tablespace or datafile.

In Oracle 10g, you can issue the ALTER DATABASE END BACKUP command when the database is open.

If you issue the command while one of the data files is offline or in read-only mode, a warning message will return:

SQL> alter database end backup;
alter database end backup
*
ERROR at line 1:
ORA-01260: warning: END BACKUP succeeded but some files found not to be in backup mode
