使用Netback備份Oracle報ora-27206錯誤處理，netbackora-27206

今天，同事的Database Backup出現問題，幫忙查看，錯誤資訊如下：

網上查詢資料如下：

查看mos發現[ID 558993.1]提供了錯誤原因和解決方案
錯誤原因：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.
解決方案：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.

查看伺服器配置，果然主機名稱配置不正確，一是將大小寫沒匹配好，二是將主機名稱裡的數字0寫成了字母o。改之，觀察備份結果，一切正常
