Oracle 存储过程解锁及表解锁和停止执行

 

查看进程:

select * from v$process;

 

根据存储过程名称查找是否被锁:

select * FROM dba_ddl_locks where name =upper('sp_1');

select * FROM dba_ddl_locks where name like upper('%sp_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; 

 

select  s.*
from v$locked_object l, dba_objects o, v$session s, v$process p
 where l.object_id = o.object_id
   and l.session_id = s.sid
   and s.paddr = p.addr
   AND object_name= upper(''表或存储过程名字');

 

查找 SID:

select t.sid,t.serial# from v$session t 
where t.sid=550;

 

杀死 session 解锁:

alter system kill session '550,10047' immediate;

--sid,t.serial#

 

如果利用上面的命令杀死一个进程后,进程状态被置为"killed",但是锁定的资源很长时间没有被释放,那么可以在os一级再杀死相应的进程(线程),首先执行下面的语句获得进程(线程)号:

select spid, osuser, s.program from v$session s,v$process p where 
s.paddr=p.addr and s.sid=550 

(550就是上面的sid)

 

单机:
SELECT A.PID, B.SID, B.SERIAL#, C.SQL_TEXT,A.SPID
  FROM V$PROCESS A, V$SESSION B, V$SQLAREA C
 WHERE A.ADDR = B.PADDR
   AND B.SQL_ADDRESS = C.ADDRESS

rac:

SELECT A.PID, B.SID, B.SERIAL#, C.SQL_TEXT,A.SPID
  FROM GV$PROCESS A, GV$SESSION B, GV$SQLAREA C
 WHERE A.ADDR = B.PADDR
   AND B.SQL_ADDRESS = C.ADDRESS

 

再到 linux 下执行 kill 命令:

kill -9 pid

 

杀 会话:

select  a.USERNAME,a.MACHINE, sql_text,'alter system kill session '''||a.SID||','||a.SERIAL#||',@'||a.INST_ID||'''immediate;' ,status 
from gV$session a inner join GV$sql b on a.sql_id=b.sql_id 
WHERE status = 'ACTIVE'

 

定时任务,杀掉特定服务器上执行超过一个小时的语句:

create or replace procedure ks_kill_sp_timeout

as
    v_sql varchar2(2000);
    v_count number;
begin

select count(distinct 'alter system kill session '''||a.SID||','||a.SERIAL#||',@'||a.INST_ID||''' immediate;')  into v_count
from gV$session a inner join GV$sql b on a.sql_id=b.sql_id
WHERE a.status = 'ACTIVE'
and a.MACHINE = 'db'
and ceil( (sysdate - a.SQL_EXEC_START) * 24 * 60) >= 60 ;

if v_count > 0 then
  select distinct 'alter system kill session '''||a.SID||','||a.SERIAL#||',@'||a.INST_ID||''' immediate;'  into v_sql
  from gV$session a inner join GV$sql b on a.sql_id=b.sql_id
  WHERE a.status = 'ACTIVE'
  and a.MACHINE = 'db'
  and ceil( (sysdate - a.SQL_EXEC_START) * 24 * 60) >= 60 ;
  
  dbms_output.put_line(v_sql);  
  execute immediate v_sql;
else
  dbms_output.put_line(v_count);
end if;


end;
