Oracle查看逻辑读、物理读资源占用排行的SQL语句

Shun

查看逻辑读前10的SQL：

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：

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;
