This article describes how to find high-consumption Oracle statements, you can refer to the SQL statement used to generate the AWR report before running the following script. (The program script is generally stored in rdbms/admin under $ ORACLE_HOME and is named awrrpt. SQL, you need to enter the number of days for generating the AWR Report) Find the start and end snapshot numbers: begin_snap and end_snap.

The Code is as follows:


Set line 1000
Set linesize 200
Set pagesize 2000
Sets long 999999
Set echo on
Set markup html on
Select res .*
From (select to_char (d. end_interval_time, 'yyyy-mm-dd '),
A. PARSING_SCHEMA_NAME,
C. MODULE,
A. SQL _id,
A.exe cs as execution times,
ROUND (a. cpu_times/a.exe cs, 2) as single execution time,
A. cpu_times as cpu consumption time,
ROUND (a. cpu_times/B. sum_time * 100, 2) as cpu usage,
A. buffer_gets as logical read,
ROUND (a. buffer_gets/B. sum_buffer * 100, 2) as logical read percentage,
A. disk_read as physical read,
ROUND (a. disk_read/B. sum_disk * 100, 2) as physical read percentage,
