  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
  
  Recovery Manager: Release 10.1.0.3.0 - 64bit Production

  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 /

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