使用Netback备份Oracle报ORA-27206错误处理
今天，同事的Oracle数据库备份出现问题，帮忙查看，错误信息如下：

网上查询资料如下：
查看mos发现[ID 558993.1]提供了错误原因和解决方案
错误原因：RMAN backup to tape using veritas netbackup，The MML parameters like NB_ORA_CLIENT and NB_ORA_SERV were not given in proper case while configuring channel in RMAN backup.
解决方法：The NB_ORA_CLIENT and NB_ORA_SERV MML parameters are case sensitive. So make sure to give these parameters in same case while allocating or configuring RMAN channel as it is configure in Veritas server.
查看服务器配置，果然主机名配置不正确，一是将大小写没匹配好，二是将主机名里的数字0写成了字母o。改之，，观察备份结果，一切正常
