查看用户连接

断掉某一连接

查看连接ip

oracle中查看用户连接
select username,sid,serial#,status from v$session where username <>'1';
select sid,ses.serial#,ses.username,pro.username,pro.spid,status
from v$session ses,v$process pro
where ses.username='PRODUCT' and ses.paddr=pro.addr;
select ses.username,pro.* from v$process pro,v$session ses where ses.paddr=pro.addr and ses.username<>'1';
从上面的sql中可以获得连接的用户、oracle sid以及os的进程号等信息
利用上述信息，可以停掉连接
alter system kill session 'sid,serial#';或者根据os的进程号直接kill
上述sql无法获得连接的client的ip，不知道有没有现成的view能提供呢？
要获取ip
方法1：$ORACLE_HOME/network/log/listener_orarac1.log
方法2：需要建立logon的trigger
create table session_history。。。

CREATE OR REPLACE TRIGGER logon_history
AFTER LOGON ON database
BEGIN
insert into session_history
select username,SYSDATE,SYS_CONTEXT('USERENV','IP_ADDRESS') from v$session where audsid = userenv( 'sessionid' ) ;
commit;
END;

方法3：netstat -anp |grep 1521

其中5582/oracleorcl1中的5582就是os的进程号
