http://www.gipsky.com/
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>

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

You have new mail.



$ id



uid=101(oracle) gid=101(dba)



$ sqlplus "/ as sysdba"

3.执行恢复



$ rman target /

RMAN> alter database open;

4.最后不要忘记解冻HA



$ exit



# id



uid=0(root) gid=1(other)



# hagrp -unfreeze MMSDB -persistent
