查询Oracle正在执行和执行过的SQL语句

--正在执行的select a.username, a.sid,b.SQL_TEXT, b.SQL_FULLTEXT

from v$seion a, v$sqlarea bwhere a.sql_addre = b.addre

---执行过的select b.SQL_TEXT,b.FIRST_LOAD_TIME,b.SQL_FULLTEXT

from v$sqlarea b

where b.FIRST_LOAD_TIME between '2009-10-15/09:24:47' and'2009-10-15/09:24:47' order by b.FIRST_LOAD_TIME

（此方法好处可以查看某一时间段执行过的sql，并且 SQL_FULLTEXT 包含了完整的 sql 语句）其他

select OSUSER,PROGRAM,USERNAME,SCfrom V$SESSION A LEFT JOIN V$SQL B ON A.SQL_ADDRESS=B.ADDRESS AND A.SQL_HASH_VALUE=B.HASH_VALUE order by b.cpu_time desc

HEMANAME,B.Cpu_Time,STATUS,B.SQL_TEXTselect addre, sql_text, piece

from v$seion, v$sqltextwhere addre = sql_addre

--and machine = order by addre, piece

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
