oracle查询当前运行的进程、查询被锁的对象、杀Seesion的SQL、设置SQL语句计时等教程

oracle查询当前运行的进程

select a.program, b.spid, c.sql_text
  from v$session a, v$process b, v$sqlarea c
 where a.paddr = b.addr
   and a.sql_hash_value = c.hash_value
   and a.username is not null;

查询被锁的对象

SELECT a.object_id, a.session_id, b.object_name, c.*
  FROM v$locked_object a, dba_objects b, v$session c
 WHERE a.object_id = b.object_id
   AND a.SESSION_ID = c.sid(+)

杀Seesion的SQL

　alter system kill session 'sid, serial#'   

如上面查出来的一条记录的sid是53, serial#为663,就执行以下的语句 alter system kill session ‘53,663’

设置SQL语句计时

set timing on;
