oracle11gR2下scott用戶以及表的建立

在oralce數據庫安裝完成之後，沒有scott用戶以及練習表，如何建立用戶以及系統提供的表呢？

操作步驟：

找到系統帶的sql文件（utlsample.sql）

[root@kyeup01 admin]# pwd
/oracle/app/oracle/product/11.2.0/rdbms/admin
[root@kyeup01 admin]# ll utlsampl.sql 
-rw-r--r--. 1 oracle oinstall 3676 6月   2 2006 utlsampl.sql
 

根據SQL的內容操作

新建用戶並授權

-- 刪除系統帶的用戶
DROP USER SCOTT CASCADE;
DROP USER ADAMS CASCADE;
DROP USER JONES CASCADE;
DROP USER CLARK CASCADE;
DROP USER BLAKE CASCADE;
<!-- more -->
-- 授權scott相應的權限
GRANT CONNECT,RESOURCE,UNLIMITED TABLESPACE TO SCOTT IDENTIFIED BY tiger;

DROP PUBLIC SYNONYM PARTS;

查詢表（使用pl/sql）

疑問

以上的方法可能不是最優的方法，相當於把utlsample.sql手工執行了。
網上的資料大都是這樣執行的：

[oracle@kyeup01 admin]$ sqlplus ‘/as sysdba‘
SQL*Plus: Release 11.2.0.4.0 Production on Fri Jun 15 11:46:27 2018

SP2-0310: unable to open file "/oracle/app/oracle/product/11.2.0/rdbms/admin/utlsample.sql"

其實命令操作錯誤，正確的操作如下：

[oracle@kyeup01 admin]$ sqlplus ‘/as sysdba‘
