oracle中scott用户的创建

原创作品，转载请在文章开头显眼位置注明出处：https://www.cnblogs.com/sunshine5683/p/10046716.html

今天，接着上次的学习进度继续前进，在此过程中，使用scott用户登录时候显示scott用户不存在，于是进行scott用户的解锁操作

SQL> alter user scott account unlock;
alter user scott account unlock
           *
第 1 行出现错误:

ORA-01918: 用户 'SCOTT' 不存在

由上面的过程可以很轻松的看出，scott用户不存在，然后进行scott用户的创建，网上有好多类似的创建方法，说在某个目录下面可以找到scott.sql文件，然后用相应的命令执行此操作便可以，但是在实际操作的过程中并没有发现该文件，可能是本人安装的数据库中本来就没有的原因，本人主要查找的目录有：

 usr/local/oracle/product/rdbms/admin/   目录，因为本人的数据库就在此目录下，并没有找到，那么就继续构造该文件

首先：在客户机上建立一个txt文件，然后在文件中输入以下内容：

其次，将新建的txt文件保存为.sql文件，注意后缀名隐藏的话打开计算机----组织----文件夹选项----在隐藏已知文件的扩展名前面的√去掉，然后将.txt改成.sql

再次，将刚刚保存好的sql文件拷贝到linux服务器的 usr/local/oracle/product/rdbms/admin/目录下，可以看看创建时间

 然后，使用命令：su - oracle -c 'sqlplus / as sysdba'切换到sqlplus命令行模式，执行以下语句

@$ORACLE_HOME/rdbms/admin/scott.sql

执行前：

执行：

执行后：

到此，scott用户的创建已经完成。

现在使用刚刚创建好的scott用户登录，但是发现密码不知道是什么，并不是tiger，然后使用sys用户对scott用户重新设置密码，如下：

 最终顺利完成！
