oracle修改連接空閑自動斷開

 

空閑3分鍾自動斷開

SELECT * FROM DBA_PROFILES;

CREATE PROFILE KILLIDLE LIMIT IDLE_TIME 3;

alter PROFILE DEFAULT LIMIT IDLE_TIME 3; 

 

有必要還可以根據業務修改連接時長，超過多少時間就干掉連接

alter PROFILE DEFAULT  LIMIT CONNECT_TIME UNLIMITED; 

 

一些輔助命令查進程和session

select count(*) from v$process;

select count(*) from v$session;

select max(pga_used_mem)/1024/1024 M from v$process; 

select min(pga_used_mem)/1024/1024 M from v$process where pga_used_mem>0; 

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'
