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.
