How do I cancel a rman job from command line?

Question

Hello to all,
I am having some problems with a rman job that is running via OEM-GC. I get an error message regading the SPFILE and control file being locked due to another job accessing it. I found this in the RMAN ref guide:
To determine which job is holding the conflicting enqueue:
1. After you see the first RMAN-08512: waiting for snapshot controlfile enqueue message, start a new SQL*Plus session on the target database:
% sqlplus sys/sys_pwd@prod1
2. Execute the following query to determine which job is causing the wait:
SELECT s.sid, username AS "User", program, module, action, logon_time "Logon", l.*
FROM v$session s, v$enqueue_lock l
WHERE l.sid = s.sid and l.type = 'CF' AND l.id1 = 0 and l.id2 = 2;
You should see output similar to the following (the output in this example has been truncated):
SID User Program Module Action Logon
9 SYS rman@h13 (TNS V1-V3) backup full datafile: c1 0000210 STARTED 21-JUN-99
Solution
After you have determined which job is creating the enqueue, you can do one of the following:
* Wait until the job creating the enqueue completes
* Cancel the current job and restart it once the job creating the enqueue completes
* Cancel the job creating the enqueue
So with this in mind; How do I cancel the job from RMAN command line!!!
This is my output by the way:
SID User PROGRAM MODULE ACTION Logon ADDR KADDR SID TY ID1 ID2 LMODE REQUEST CTIME BLOCK
475 SYS [email protected] (TNS V1-V3) backup full datafile 0000018 STARTED16 23-APR-09 00000023EB8D488 000000023EB8D4A8
475 CF 0 2 4 0 113123 0
Any help will be gratefully received
Thanks to all that reply

I used the following to get the spid and killed the process on the OS.
set linesize 120
col sid for 999
col username for a14 trunc
col osuser for a18 trunc
col spid for 99990
col logon_time for a12
col status for a9 trunc
col machine for a26 trunc
col running for a10 trunc
select s.sid
, s.username
, s.osuser
, s.machine
, s.status
, p.spid spid
, to_char( logon_time, 'Mon dd@hh24:mi') logon_time
, rtrim (s.module)||decode( nvl(length( rtrim(s.module)),0),0,'',' ')|| upper(s.program) running
from v$session s
, v$process p
where ( p.addr = s.paddr ) and s.type!='BACKGROUND'
and upper(s.program) not like '%CJQ0%' and s.program is not null and s.username is not null
order by s.sid;
