SQL
SELECT sid, spid, client_info
FROM v$process p, v$session s
WHERE p.addr = s.paddr
AND client_info LIKE '%rman%';
SID SPID CLIENT_INFO

（2）根据第（1）中得到的进程号，终止RMAN备份
注：这里既要kill 掉RMAN备份脚本的PID，?也要kill 掉RMAN中分配的各个通道的PID

（3）核实进程是否还存在
此时RMAN备份操作已经被终止。查看（1）中的SQL语句时，结果为空。
终止进程并不能结束备份，需要结束备份对应的job；
1、查看备份job
select job_name,state from dba_datapump_jobs;
2、在退出导出监视界面后，可以通过下面语句重新打开expdp界面
Expdp system/test ATTACH=system.export_job10 --第一步查出的job名称
3、结束job
Export kill_job
关闭所有服务可以，但是通常来说不需要关闭所有服务，只需要数据库不是open状态就可以了
一般做法是，用sqlplus sys/password@servicename as sysdba
sqlshutdown immediate
然后就可以进行冷备了
备份结束后
sqlstartup
