查看刚执行过得SQL文本

1、查看执行过得SQL脚本

select sql_text, last_load_time, SQL_FULLTEXT

 order by last_load_time desc;

---执行过的 select b.SQL_TEXT,b.FIRST_LOAD_TIME,b.SQL_FULLTEXT   from v$sqlarea b   

2、 ---正在执行的 select a.username, a.sid,b.SQL_TEXT, b.SQL_FULLTEXT   from v$session a, v$sqlarea b  where a.sql_address = b.address 

3、查找前十条性能差的sql.  SELECT * FROM (select PARSING_USER_ID,EXECUTIONS,SORTS,  COMMAND_TYPE,DISK_READS,sql_text FROM v$sqlarea  order BY disk_reads DESC )where ROWNUM<10 ;  4、查看占io较大的正在运行的session  SELECT se.sid,se.serial#,pr.SPID,se.username,se.status,  se.terminal,se.program,se.MODULE,se.sql_address,st.event,st.  p1text,si.physical_reads,  si.block_changes FROM v$session se,v$session_wait st,  v$sess_io si,v$process pr WHERE st.sid=se.sid AND st.  sid=si.sid AND se.PADDR=pr.ADDR AND se.sid>6 AND st.  wait_time=0 AND st.event NOT LIKE '%SQL%' ORDER BY physical_reads DESC
