说明:
此处的1377指的是数据库进程号,获取方式如下:
这个sql的查询结果理论上会有0,1,2,3这四个值,所以输出的时候需要根据结果使用条件判断输出接到到指定的日志中。
select sum(temp_cnt) from (
select case when count(1)>0 then 1 else 0 end temp_cnt from (
SELECT datediff(ss,last_recv_time,sysdate) Y_EXETIME
FROM V$SESSIONS WHERE STATE='ACTIVE')
where Y_EXETIME>=1 union all
select case when count(1)>500 then 2 else 0 end temp_cnt from v$sessions where state = 'ACTIVE');
