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.
