Sybase 和 Oracle 数据库 查询死锁的方法

Sybase 查询死锁spid：

select l.spid,
       locktype=convert(char(12),name),
       dbname=convert(char(15),db_name(l.dbid)),
       'table'=convert(char(15),object_name(l.id,l.dbid)),
       page,
       class=convert(char(15),class),
       hostname,
       cmd
from master..syslocks l,master..spt_values v,master..sysprocesses p
where l.type = v.number and
      v.type = 'L' and
      l.spid = p.spid
order by spid

sp_who  查看锁表情况

sp_lock  查看被锁的表的id号

dbcc traceon(3604)

dbcc sqltext(pid)  查看pid相关的sql 需要sa权限
注意：执行dbcc sqltext()之前需要先执行dbcc traceon(3604) 

set showplan on 查看sql执行计划

set statistics time on 查看sql执行时间
======================================================================
Oracle 查询死锁spid：

select   p.spid,a.serial#, c.object_name,b.session_id,b.oracle_username,b.os_user_name 
  from   v$process   p,v$session   a,   v$locked_object b  ,all_objects   c  
   where   p.addr=a.paddr   and   a.process=b.process   and   c.object_id=b.object_id ;

拥有权限才能  kill spid
