查看Oracle链接客户端的IP等信息

查看当前链接ORACLE的IP

查看当前链接的IP(查看当前自己链接IP，不能查看其它的链接的IP)：

SELECT USER,SID,SERIAL#,UTL_INADDR.GET_HOST_ADDRESS AS HOST,SYS_CONTEXT('USERENV','IP_ADDRESS') AS LOCAL,SYSDATE FROM V$SESSION WHERE AUDSID=SYS_CONTEXT('USERENV','SESSIONID');

ORCL 214 1758 ::1 192.168.1.240 2018-01-26 10:52:29

查看所有链接Oracle的客户端的IP等信息：

step1: 查看每个oracle帐户的连接总数：

select username,count(username) from v$session where username is not null group by username; 

USERNAME  COUNT(USERNAME)
ORCL 117
SYS 1

step2: 缺省从 v$session 中不能直接获得客户端 IP，可以在数据库中创建一个追踪客户端IP地址的触发器：

create or replace trigger on_logon_trigger after logon on database  
begin  
    dbms_application_info.set_client_info(sys_context('userenv', 'ip_address'));  
end;   
/  

step3: 比较常用的显示客户端信息的sql(通过step2执行以后，再执行step3，新链接上来的客户端信息，就能显示ip了)

select sid,serial#,username,program,machine,client_info  
from v$session  
where username is not null  
order by username,program,machine;
