【ORACLE】查看正在运行的的SQL

查看 Oracle 正在执行的 sql 语句以及发起的用户

SELECT b.sid oracleID,  
       b.username 用户名,  
       b.serial#,  
       paddr,  
       sql_text 正在执行的SQL,  
       b.machine 计算机名称
FROM v$process a, v$session b, v$sqlarea c  
WHERE a.addr = b.paddr  
   AND b.sql_hash_value = c.hash_value 

查询当前用户正在执行的SQL

select a.sid,
       a.serial#,
       a.paddr,
       a.machine,
       nvl(a.sql_id, a.prev_sql_id) sql_id,
       b.sql_text,
       b.sql_fulltext,
       b.executions,
       b.first_load_time,
       b.last_load_time,
       b.last_active_time,
       b.disk_reads,
       b.direct_writes,
       b.buffer_gets
  from v$session a, v$sql b
 where a.username = sys_context('USERENV', 'CURRENT_USER')
   and a.status = 'ACTIVE' 
   and nvl(a.sql_id, a.prev_sql_id) = b.sql_id;

查询当前被锁的表

SELECT l.session_id sid,  
       s.serial#,  
       l.locked_mode 锁模式,  
       l.oracle_username 登录用户,  
       l.os_user_name 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#;  

解除锁命令

alter system kill session 'sid,serial#'
