查看Oracle耗时Sql

--1、查看耗时SQL

select *

from (select v.sql_id,

v.child_number,

v.sql_text,

v.elapsed_time,

v.cpu_time,

v.disk_reads,

rank() over(order by v.elapsed_time desc) elapsed_rank

from v$sql v) a

where elapsed_rank <= 10;

-- 2.查看CPU消耗时间最多的前10条SQL语句

select *

from (select v.sql_id,

v.child_number,

v.sql_text,

v.elapsed_time,

v.cpu_time,

v.disk_reads,

rank() over(order by v.cpu_time desc) elapsed_rank

from v$sql v) a

where elapsed_rank <= 10;

--3.查看消耗磁盘读取最多的前10条SQL语句

select *

from (select v.sql_id,

v.child_number,

v.sql_text,

v.elapsed_time,

v.cpu_time,

v.disk_reads,

rank() over(order by v.disk_reads desc) elapsed_rank

from v$sql v) a

where elapsed_rank <= 10;
