oracle中scott用戶的創建

原創作品，轉載請在文章開頭顯眼位置註明出處：https://www.cnblogs.com/sunshine5683/p/10046716.html

今天，接著上次的學習進度繼續前進，在此過程中，使用scott用戶登錄時候顯示scott用戶不存在，於是進行scott用戶的解鎖操作

SQL> alter user scott account unlock;
alter user scott account unlock
           *
第 1 行出現錯誤:

ORA-01918: 用戶 'SCOTT' 不存在

由上面的過程可以很輕鬆的看出，scott用戶不存在，然後進行scott用戶的創建，網上有好多類似的創建方法，說在某個目錄下麵可以找到scott.sql文件，然後用相應的命令執行此操作便可以，但是在實際操作的過程中並沒有發現該文件，可能是本人安裝的資料庫中本來就沒有的原因，本人主要查找的目錄有：

 usr/local/oracle/product/rdbms/admin/   目錄，因為本人的資料庫就在此目錄下，並沒有找到，那麼就繼續構造該文件

首先：在客戶機上建立一個txt文件，然後在文件中輸入以下內容：

其次，將新建的txt文件保存為.sql文件，註意尾碼名隱藏的話打開電腦----組織----文件夾選項----在隱藏已知文件的擴展名前面的√去掉，然後將.txt改成.sql

再次，將剛剛保存好的sql文件拷貝到linux伺服器的 usr/local/oracle/product/rdbms/admin/目錄下，可以看看創建時間

 然後，使用命令：su - oracle -c 'sqlplus / as sysdba'切換到sqlplus命令行模式，執行以下語句

@$ORACLE_HOME/rdbms/admin/scott.sql

執行前：

執行：

執行後：

到此，scott用戶的創建已經完成。

現在使用剛剛創建好的scott用戶登錄，但是發現密碼不知道是什麼，並不是tiger，然後使用sys用戶對scott用戶重新設置密碼，如下：

 最終順利完成！
