如何kill掉RMAN备份进程

题记：最近客户的一套订购数据库经常会因为数据及业务压力太大，在RMAN进行全备或是增备时，而此时业务有大量要处理时，系统资源就会被耗尽，会影响到业务的正常，所以常有时需要先终止掉RMAN备份，这里提供了我在处理过程中的方法，希望大家喜欢！

本文的目的就是在紧急状态下，需要立即终止正在进行的RMAN备份进程。

####查看RMAN备份进度，才40%

select sid,
       serial#,
       context,
       sofar,
       totalwork,
       round (sofar / totalwork * 100, 2) "%_complete"
from v$session_longops
where     opname like 'RMAN%'
       and totalwork != 0
       and opname not like '%aggregate%'
       and sofar <> totalwork;
       SQL> select sid,
2         serial#,
3         context,
4         sofar,
5         totalwork,
6         round (sofar / totalwork * 100, 2) "%_complete"
7    from v$session_longops
8   where     opname like 'RMAN%'
9         and totalwork != 0
10         and opname not like '%aggregate%'
11         and sofar <> totalwork;

       SID    SERIAL#    CONTEXT      SOFAR TOTALWORK %_complete
---------- ---------- ---------- ---------- ---------- ----------
       381      57130          1   10735600   27000832      39.76

（1）查看RMAN分配的各个通道的进程号
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
---------- ------------------------ -------------------------
       525 26244      rman channel=t1
      1023 26245      rman channel=t2
       699 26246      rman channel=t3

（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
