查询Oracle中正在执行和执行过的SQL语句

查询oracle正在执行的sql语句及执行该语句的用户

select b.sid oracleid,
    b.username 登录oracle用户名,
    b.serial#,
    spid 操作系统id,
    paddr,
    sql_text 正在执行的sql,
    b.machine 计算机名
from v$process a, v$session b, v$sqlarea c
where a.addr = b.paddr
  and b.sql_hash_value = c.hash_value

其它网友给出的正在执行的sql语句代码

select a.username, a.sid,b.sql_text, b.sql_fulltext
 from v$session a, v$sqlarea b 
where a.sql_address = b.address 
---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 '2016-10-1/09:24:47' and
    '2016-10-1/09:24:47' 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,schemaname,b.cpu_time,status,b.sql_text 
from 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 

select address, sql_text, piece 
 from v$session, v$sqltext 
where address = sql_address 
 -- and machine = < you machine name > 
order by address, piece 

查看正在执行sql的发起者的发放程序

select osuser 电脑登录身份,
    program 发起请求的程序,
    username 登录系统的用户名,
    schemaname,
    b.cpu_time 花费cpu的时间,
    status,
    b.sql_text 执行的sql
from 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

查出oracle当前的被锁对象

select l.session_id sid,
    s.serial#,
    l.locked_mode 锁模式,
    l.oracle_username 登录用户,
    l.os_user_name 登录机器用户名,
    s.machine 机器名,
    s.terminal 终端用户名,
    o.object_name 被锁对象名,
    s.logon_time 登录数据库时间
from v$locked_object l, all_objects o, v$session s
where l.object_id = o.object_id
  and l.session_id = s.sid
order by sid, s.serial#;

kill掉当前的锁对象可以为

alter system kill session 'sid， s.serial#‘;

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 ; 

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
