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:
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;
