对即将上线的Oracle10g ASM生产数据库进行备份恢复测试

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

RMAN> run {

2> backup database plus archivelog delete all input;   

3> delete obsolete;

4> }

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

4.最后不要忘记解冻HA

$ exit

# id

# hagrp -unfreeze MMSDB -persistent
