全卸载Oracle方法：
软件环境：
1、Windows XP + Oracle 10g
2、Oracle安装路径为：d:\Oracle
1、如果数据库配置了自动存储管理(ASM),应该先删除聚集同步服务CSS（cluster Synchronization Services).删除CSS服务的方法是在DOS命令行中执行如下命令： localconfig delete
2、在“服务”窗口中停止Oracle的所有服务。
3、在“开始”菜单中依次选择“程序”/“Oracle-OraDb10g_home1"/"Oracle Installation Products”/ ...

[Q]怎么快速查找锁与锁等待
[A]数据库的锁是比较耗费资源的，特别是发生锁等待的时候，我们必须找到发生等待的锁，有可能的话，杀掉该进程。
这个语句将查找到数据库中所有的DML语句产生的锁，还可以发现，任何DML语句其实产生了两个锁，一个是表锁，一个是行锁。
可以通过alter system kill session ‘sid,serial#’来杀掉会话
SELECT /*+ rule */ s.username,
decode(l.type,'TM','TABLE LOCK',
'TX','ROW LOCK',
