这篇文章主要介绍了Oracle查看逻辑读、物理读资源占用排行的SQL语句,需要的朋友可以参考下      

查看逻辑读前10的SQL：

复制代码代码如下:
set linesize 300;
set pagesize 300;
set long 50000;
SELECT *
FROM (
    SELECT sql_fulltext AS sql, SQL_ID,buffer_gets / executions AS "Gets/Exec",buffer_gets, executions
    FROM V$SQLAREA
    WHERE buffer_gets > 10000
    ORDER BY "Gets/Exec" DESC
)
WHERE rownum <= 10;

查看物理读前10的SQL：

复制代码代码如下:
set linesize 300;
set pagesize 300;
set long 50000;
SELECT *
FROM (
    SELECT sql_fulltext AS sql, SQL_ID,disk_reads / executions AS "Reads/Exec",disk_reads, executions 
    FROM V$SQLAREA
    WHERE disk_reads > 1000
    ORDER BY "Reads/Exec" DESC
)
WHERE rownum <= 10;
