　　新的10g ASM生产数据库即将上线，以下是上线前做的简单的备份恢复测试:
　　
　　1.首先执行备份
　　
　　$ rman target / @full_bak.sql

　　connected to target database: MMSDB (DBID=799462343)
　　
　　RMAN> run {
　　2> backup database plus archivelog delete all input;
　　3> delete obsolete;
　　4> }
　　5>
　　
　　Starting backup at 13-APR-05

　　2.冻结HA,停止数据库进行恢复
　　
　　$ id
　　uid=101(oracle) gid=101(dba)
　　$ exit
　　# id
　　uid=0(root) gid=1(other)
　　# hagrp -freeze MMSDB -persistent
　　# su - oracle

　　$ id
　　uid=101(oracle) gid=101(dba)
　　$ sqlplus "/ as sysdba"

　　3.执行恢复

　　4.最后不要忘记解冻HA
　　
　　$ exit
　　# id
　　uid=0(root) gid=1(other)
　　# hagrp -unfreeze MMSDB -persistent
