Oracle查看锁表和正在执行的Sql

查看当前被锁的表(需要有管理员权限):

--查看锁表进程SQL语句1: 
select sess.sid,
       sess.serial#,
       lo.oracle_username,
       lo.os_user_name,
       ao.object_name,
       lo.locked_mode
  from v$locked_object lo, dba_objects ao, v$session sess
 where ao.object_id = lo.object_id
   and lo.session_id = sess.sid;

查看当前正在执行的SQL语句:

select l.session_id sid,
       s.serial#,
       l.locked_mode,
       l.oracle_username,
       s.user#,
       l.os_user_name,
       s.machine,
       s.terminal,
       a.sql_text,
       a.action
  from v$sqlarea a, v$session s, v$locked_object l
 where l.session_id = s.sid
   and s.prev_sql_addr = a.address
 order by sid, s.serial#;
