oracle修改连接空闲自动断开

空闲3分钟自动断开

SELECT * FROM DBA_PROFILES;

CREATE PROFILE KILLIDLE LIMIT IDLE_TIME ;

alter PROFILE DEFAULT LIMIT IDLE_TIME ; 

有必要还可以根据业务修改连接时长，超过多少时间就干掉连接

alter PROFILE DEFAULT  LIMIT CONNECT_TIME UNLIMITED; 

一些辅助命令查进程和session

select count(*) from v$process;

select count(*) from v$session;

select max(pga_used_mem)// M from v$process; 

select min(pga_used_mem)// M from v$process where pga_used_mem>; 

select a.USERNAME,a.MACHINE, sql_text,'alter system kill session '''||a.SID||','||a.SERIAL#||',@'||a.INST_ID||''';' ,status
from gV$session a inner join GV$sql b on a.sql_id=b.sql_id
WHERE status = 'ACTIVE'
