Oracle查看逻辑读、物理读资源占用排行的SQL语句
查看逻辑读前10的SQL：
setlinesize300; setpagesize300; setlong50000; SELECT* FROM( SELECTsql_fulltextASsql,SQL_ID,buffer_gets/executionsAS"Gets/Exec",buffer_gets,executions FROMV$SQLAREA WHEREbuffer_gets>10000 ORDERBY"Gets/Exec"DESC ) WHERErownum<=10;
查看物理读前10的SQL：
setlinesize300; setpagesize300; setlong50000; SELECT* FROM( SELECTsql_fulltextASsql,SQL_ID,disk_reads/executionsAS"Reads/Exec",disk_reads,executions FROMV$SQLAREA WHEREdisk_reads>1000 ORDERBY"Reads/Exec"DESC ) WHERErownum<=10;
