开发测试程序的自动重连的功能需要对有对v$session查看和kill session权限
简单的就是赋一下select any dictionary和alter system 权限,但权限大的操作,一般考虑存储过程实现
网上实用的存储过程
DROP PROCEDURE P_KILL_SESSION;
CREATE OR REPLACE PROCEDURE p_kill_session (
p_user IN VARCHAR2,
p_sid IN VARCHAR2
)
AS
v_sql VARCHAR2 (327);
BEGIN
SELECT 'alter system kill session '''|| SID || ',' || serial# ||''''
INTO v_sql
FROM v$session
WHERE username = p_user AND SID = p_sid;
dbms_output.put_line(v_sql);
EXECUTE IMMEDIATE v_sql;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
raise_application_error
(-20001,
'sid:'
|| p_sid
|| ' does not exists, or the session user is not '
|| p_user
);
END;
/
CREATE OR REPLACE procedure p_kill_user_session(p_sid in number)
as
v_username varchar2(100);
v_sid number;
begin
select sys_context('userenv', 'session_user'),sys_context('userenv', 'sid') INTO v_username, v_sid from dual;
if p_sid != v_sid then
p_kill_session(v_username, p_sid);
else
raise_application_error(-20000, 'can not kill current session!');
end if;
end;
/
注意的是存储过程里v$session授权问题,此表是sys.v_v$session的同义词,在过程里必须要表的原有属主(sys)进行授权,不管你是否有dba权限
