运维DBA工程师在巡检时发现alert日志存在错误ORA-19583 ORA-27206 ORA-06512，结合mos分析原因为RMAN备份导致报错

1.检查alert日志发现近期数据库出现了ORA-19583 ORA-27206 ORA-06512错误

ORA-27206: requested file not found in media management catalog

ORA-06512: at "SYS.DBMS_BACKUP_RESTORE", line 625

3.结合mos解决ora错误

ora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.

案例分析解决方法：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.
