nbu 恢复 oracle 控制文件 报错

zhangmq

各位好！小弟在测试环境恢复oracle控制文件遇到些问题，情况是这样的：
1.在一部win2003 server 上安装nbu server，备份介质为磁盘空间；
2.aix 5.3安装oracle 10g。
备份oracle 10g成功，包括控制文件。不过没有将controlfile设为autobackup到磁盘，现在想从nbu备份介质中恢复。


在网上找了些资料：
3.1.bplist查看备份：

# ./bplist -C aix -S win2003 -t 4 -R /
EXIT STATUS 25: cannot connect on socket
# ping win2003
0821-062 ping: host name win2003 NOT FOUND
# ./bplist -C aix -S su182 -t 4 -R /

另外，我在另一个环境测试。用一部windows 2003虚拟机安装oracle 10g ,安装nbu，用同样的方式备份后恢复是成功的，是不是跟系统差异有关。有在备份服务器C:\Program Files\VERITAS\NetBackup\db\altnames创建No.Restrictions。

/c-*
这些都应该是aotubanckup的controlfile吧

备份服务器activity monitor报错见附件，错误代码37

很奇怪，为什么在备份服务器显示客户端为主机“localhost，是不是问题关键？

    这一句restore controlfile from '/ctrl_u1ol7o75m_s56_p1_t712776886';
    去掉" /"
改成restore controlfile from 'ctrl_u1ol7o75m_s56_p1_t712776886';

这种回复方式不需set DBID

/etc/hosts编辑正确吗？
