oracle 12c 中scott账户与表问题

658uhr

之前安装了12c版本，最近做练习发现怎么没有scott用户和11g自带的emp，dept等等的表。于是尝试解锁用户，发现用户不存在

1 2 3 4 5

SQL> alter user scott account unlock; alter user scott account unlock            * ERROR at line 1: ORA-01918: user 'SCOTT' does not exist

手动创建用户，出错，和11g不太一样

1 2 3 4 5

SQL> create user scott identified by oracle; create user scott identified by oracle             * ERROR at line 1: ORA-65096: invalid common user or role name

原因和pdb，cdb有关。pdb和cdb是12c的新特性，没有具体学过，不知道是神马意思，不过可以参考这篇文章：http://www.iyunv.com/tzetze/p/3665903.html

查看错误ORA--65096

1 2 3 4 5 6 7 8 9

SQL>  !oerr ora 65096 65096, 00000, "invalid common user or role name" // *Cause:  An attempt was made to create a common user or role with a name //          that wass not valid for common users or roles.  In addition to //          the usual rules for user and role names, common user and role //          names must start with C## or c## and consist only of ASCII //          characters. // *Action: Specify a valid common user or role name. //

在CDB中用户得以C##开头。

试了一下在sql中@/u01/app/oracle/product/12.1.0/db_1/rdbms/admin/utlsampl.sql，也不行，因为里面的用户名有问题
于是自己改写了这个脚本，步骤如下：

当前路径
[oracle@localhost ~]$ pwd
/home/oracle
复制一个副本到当前目录
[oracle@localhost ~]$ cp /u01/app/oracle/product/12.1.0/db_1/rdbms/admin/utlsampl.sql .

重命名文件为scott.sql：
[oracle@localhost ~]$ mv utlsampl.sql scott.sql

修改scott.sql：
主要是将scott用户相关的语句改为c##scott，删除最后的EXIT，修改完的scott.sql如下：
scott.sql
