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$sqlarea c
WHERE a.addr = b.paddr
AND b.sql_hash_value = c.hash_value
查看正在执行sql的发起者的发放程序：
SELECT OSUSER 电脑登录身份,
PROGRAM 发起请求的程序,
USERNAME 登录系统的用户名,
SCHEMANAME,
B.Cpu_Time 花费cpu的时间,
STATUS,
B.SQL_TEXT 执行的sql
FROM V$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$session s
WHERE l.object_id = o.object_id
AND l.session_id = s.sid
ORDER BY sid, s.serial#;
kill掉当前的锁对象:
alter system kill session 'sid， s.serial#‘;
查询当前正在执行的事务:
SELECT s.sid,
s.serial#,
s.event,
a.sql_text,
a.sql_fulltext,
s.username,
s.status,
s.machine,
s.terminal,
s.program,
a.executions,
s.sql_id,
p.spid,
a.direct_writes
FROM (SELECT * FROM v$session WHERE status = 'ACTIVE') s
LEFT JOIN v$sqlarea a
ON s.sql_id = a.sql_id
INNER JOIN v$process p
ON s.paddr = p.addr
