有的时候因为某些原因需要KILL掉RMAN进程。但是直接KILL掉RMAN进程的pid还是不能彻底杀掉，而是要连channel进程也一起KILL才可以！下面提供一个彻底KILL的方法供参考。
1、看一下KILL掉RMAN进程的pid的效果

1. [oracle@test backup]$ ps -ef|grep rman
2. oracle 15172 15039 0 Aug14 pts/0 00:00:00 sh rmanbak.sh
3. oracle 15174 15172 0 Aug14 pts/0 00:00:04 rman le/db/bin/rman target / log /backup/rmanlog_2015-08-14_2117
4. oracle 31163 15039 0 09:20 pts/0 00:00:00 grep rman
5. [oracle@test backup]$ kill 15174
6. [oracle@test backup]$ ps -ef|grep rman
7. oracle 31172 15039 0 09:20 pts/0 00:00:00 grep rman
8. [1]+ Exit 143 nohup sh rmanbak.sh > rmanbak.log
9. [oracle@test backup]$
10. [oracle@test backup]$ ps -ef|grep rman              --------这里看到rman进程已经没有了
11. oracle 31174 15039 0 09:20 pts/0 00:00:00 grep rman
12. [oracle@test backup]$ ls -l ./data/*
13. -rw-r----- 1 oracle oinstall  7259655680 Aug 14 21:50 ./data/arch_20150814_25
    -rw-r----- 1 oracle oinstall  3811864064 Aug 14 21:30 ./data/arch_20150814_26
    -rw-r----- 1 oracle oinstall  3586004992 Aug 14 21:32 ./data/arch_20150814_27
    -rw-r----- 1 oracle oinstall   214711808 Aug 14 21:31 ./data/arch_20150814_28
    -rw-r----- 1 oracle oinstall 53685395456 Aug 15 02:18 ./data/full_20150814_31
    -rw-r----- 1 oracle oinstall 32226762752 Aug 15 04:49 ./data/full_20150815_31
    -rw-r----- 1 oracle oinstall 32511107072 Aug 15 09:20 ./data/full_20150815_32
    [oracle@test backup]$   ls -l ./data/*
    -rw-r----- 1 oracle oinstall  7259655680 Aug 14 21:50 ./data/arch_20150814_25
    -rw-r----- 1 oracle oinstall  3811864064 Aug 14 21:30 ./data/arch_20150814_26
    -rw-r----- 1 oracle oinstall  3586004992 Aug 14 21:32 ./data/arch_20150814_27
    -rw-r----- 1 oracle oinstall   214711808 Aug 14 21:31 ./data/arch_20150814_28
    -rw-r----- 1 oracle oinstall 53685395456 Aug 15 02:18 ./data/full_20150814_31
    -rw-r----- 1 oracle oinstall 32226762752 Aug 15 04:49 ./data/full_20150815_31
    -rw-r----- 1 oracle oinstall 32537321472 Aug 15 09:20 ./data/full_20150815_32
    [oracle@test backup]$   ls -l ./data/*
    -rw-r----- 1 oracle oinstall  7259655680 Aug 14 21:50 ./data/arch_20150814_25
    -rw-r----- 1 oracle oinstall  3811864064 Aug 14 21:30 ./data/arch_20150814_26
    -rw-r----- 1 oracle oinstall  3586004992 Aug 14 21:32 ./data/arch_20150814_27
    -rw-r----- 1 oracle oinstall   214711808 Aug 14 21:31 ./data/arch_20150814_28
    -rw-r----- 1 oracle oinstall 53685395456 Aug 15 02:18 ./data/full_20150814_31
    -rw-r----- 1 oracle oinstall 32226762752 Aug 15 04:49 ./data/full_20150815_31
    -rw-r----- 1 oracle oinstall 32548855808 Aug 15 09:21 ./data/full_20150815_32
14. 这个文件还在不断的增加大小，说明后台rman还在备份。

2、找到channel的进程号
我的备份设置了3个通道，因为有2个通道报错，所以我才要停掉RMAN，下面找出3个channel。

1. SQL> SELECT sid, spid, client_info
   
2.   2 FROM v$process p, v$session s
   
3.   3 WHERE p.addr = s.paddr
   
4.   4 AND client_info LIKE '%rman%';
   
5. 
   
6.        SID SPID CLIENT_INFO
   
7. ---------- ------------ ------------------------------
   
8.        614 15182 rman channel=c1
   
9.        648 15183 rman channel=c2
   
10.        781 15184 rman channel=c3

3、杀掉channel的进程
下面就杀掉3个channel的进程，这样才能完全停止rman。

1. [oracle@test backup]$ ps -ef|grep 15182
2. oracle 15182 1 72 Aug14 ? 08:41:15 oracleoutdb (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
3. oracle 31192 15039 0 09:21 pts/0 00:00:00 grep 15182
4. [oracle@test backup]$ kill -9 15182
5. [oracle@test backup]$ ps -ef|grep 15183
6. oracle 15183 1 69 Aug14 ? 08:20:20 oracleoutdb (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
7. oracle 31234 15039 0 09:22 pts/0 00:00:00 grep 15183
8. [oracle@test backup]$ kill -9 15183
9. [oracle@test backup]$ ps -ef|grep 15184
10. oracle 15184 1 75 Aug14 ? 09:08:47 oracleoutdb (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
11. oracle 31248 15039 0 09:22 pts/0 00:00:00 grep 15184
12. [oracle@test backup]$ kill -9 15184
13. [oracle@test backup]$
14. [oracle@test backup]$ ls -l ./data/*
15. -rw-r----- 1 oracle oinstall 7259655680 Aug 14 21:50 ./data/arch_20150814_25
16. -rw-r----- 1 oracle oinstall 3811864064 Aug 14 21:30 ./data/arch_20150814_26
17. -rw-r----- 1 oracle oinstall 3586004992 Aug 14 21:32 ./data/arch_20150814_27
18. -rw-r----- 1 oracle oinstall 214711808 Aug 14 21:31 ./data/arch_20150814_28
19. -rw-r----- 1 oracle oinstall 53685395456 Aug 15 02:18 ./data/full_20150814_31
20. -rw-r----- 1 oracle oinstall 32226762752 Aug 15 04:49 ./data/full_20150815_31
21. -rw-r----- 1 oracle oinstall 32956751872 Aug 15 09:23 ./data/full_20150815_32
22. [oracle@test backup]$
23. [oracle@test backup]$ ls -l ./data/*
24. -rw-r----- 1 oracle oinstall 7259655680 Aug 14 21:50 ./data/arch_20150814_25
25. -rw-r----- 1 oracle oinstall 3811864064 Aug 14 21:30 ./data/arch_20150814_26
26. -rw-r----- 1 oracle oinstall 3586004992 Aug 14 21:32 ./data/arch_20150814_27
27. -rw-r----- 1 oracle oinstall 214711808 Aug 14 21:31 ./data/arch_20150814_28
28. -rw-r----- 1 oracle oinstall 53685395456 Aug 15 02:18 ./data/full_20150814_31
29. -rw-r----- 1 oracle oinstall 32226762752 Aug 15 04:49 ./data/full_20150815_31
30. -rw-r----- 1 oracle oinstall 32956751872 Aug 15 09:23 ./data/full_20150815_32
31. -------KILL了3个channel进程后，文件不在增加
32. SQL> SELECT sid, spid, client_info  
      2       FROM v$process p, v$session s  
      3       WHERE p.addr = s.paddr  
      4       AND client_info LIKE '%rman%';
    
    no rows selected
    SQL> exit
    Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production
    With the Partitioning, Data Mining and Real Application Testing options
    [oracle@test backup]$ ps -ef|grep rman
33. oracle 31258 15039 0 09:23 pts/0 00:00:00 grep rman

这样整个RMAN进程就停了。
