数据库在Open状态下，如何使用RMAN进行全备？

1、登陆

[oracle@DG1 ubackup]$ rman target sys/oracle@db200 nocatalog

Recovery Manager: Release 11.2.0.1.0 - Production on Wed Mar 27 18:22:10 2013

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to target database: POLI (DBID=3718810889)
using target database control file instead of recovery catalog

2、执行备份

RMAN> backup database format '/u01/ubackup/wb_%U';

Starting backup at 27-MAR-13
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=132 device type=DISK
channel ORA_DISK_1: starting full datafile backup set

channel ORA_DISK_1: backup set complete, elapsed time: 00:03:34
Finished backup at 27-MAR-13

Starting Control File and SPFILE Autobackup at 27-MAR-13

Finished Control File and SPFILE Autobackup at 27-MAR-13

3、备份完成后，将当前的日志进行归档

RMAN> sql 'alter system archive log current';

sql statement: alter system archive log current
