当然首先要装好oracle 11g
然后还要有sqlplus，这个在oracle11g的时候应该都会配上的
进入正题，如果oracle/plsql没scott账户，如何创建
先找到oracle安装目录下的soctt.sql
我的是在：
e:\app\91959\product\11.2.0\dbhome_1\admin
如果没有soctt.sql，先建立一个txt文件，复制下面的代码进去，然后改成sql文件：
rem copyright (c) 1990 by oracle corporation
rem name
rem utlsampl.sql
rem function
rem notes
rem modified
rem gdudey 06/28/95 - modified for desktop seed database
rem glumpkin 10/21/92 - renamed from sqlbld.sql
rem blinden 07/27/92 - added primary and foreign keys to emp and dept
rem rlim 04/29/91 - change char to varchar2
rem mmoore 04/08/91 - use unlimited tablespace priv
rem pritto 04/04/91 - change sysdate to 13-jul-87
rem mendels 12/07/90 - bug 30123;add to_date calls so language independent

在sqlplus运行你刚创建的scott.sql，即上面那句
然后还需要为soctt用户解锁，要切换到sys管理员才能操作，执行红框的代码就解锁成功了，这样就大功告成了
