目标：
你可以在RAC database中来kill session，而不用考虑该session是从哪个intance上产生的。这是11g的新特性。

解决方案：

To kill a session in RAC database use the following syntax.

sql> conn / as sysdba

sql> alter system kill session 'sid, serial#, @inst_id';

For Example :

SQL@racdb1> select inst_id,sid,serial#,username from gv$session where username is not null and username not like 'SYS%'; 

INST_ID SID SERIAL# USERNAME 
---------- ---------- ---------- ------------------------------ 
1                123        76       DBSNMP 

1 rows selected. 

SQL@racdb2> conn scott/tiger 
Connected. 

SQL@racdb1> select inst_id,sid,serial#,username from gv$session where username is not null and username not like 'SYS%'; 

INST_ID SID SERIAL# USERNAME 
---------- ---------- ---------- ------------------------------ 
2                115    17816        SCOTT 
1                123         76         DBSNMP 

2 rows selected. 

SQL@racdb1> alter system kill session '115,17816,@2'; 

System altered. 

SQL@racdb1> conn scott/tiger 
Connected. 

SQL@racdb1> select inst_id,sid,serial#,username from gv$session where username is not null and username not like 'SYS%'; 

INST_ID SID SERIAL# USERNAME 
---------- ---------- ---------- ------------------------------ 
1                110      45316         SCOTT 
1                123            76         DBSNMP 

2 rows selected. 

sql> alter system kill session '110,45316,@1';
System altered.
