之前安裝了12c版本，最近做練習發現怎麼沒有scott用戶和11g自帶的emp，dept等等的表。於是嘗試解鎖用戶，發現用戶不存在
SQL> alter user scott account unlock; alter user scott account unlock * ERROR at line 1: ORA-01918: user 'SCOTT' does not exist
手動創建用戶，出錯，和11g不太一樣
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有關。pdb和cdb是12c的新特性，沒有具體學過，不知道是神馬意思，不過可以參考這篇文章：http://www.cnblogs.com/tzetze/p/3665903.html
查看錯誤ORA--65096
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中用戶得以C##開頭。
於是自己改寫了這個腳本，步驟如下：
當前路徑
[oracle@localhost ~]$ pwd
/home/oracle
複製一個副本到當前目錄
[oracle@localhost ~]$ cp /u01/app/oracle/product/12.1.0/db_1/rdbms/admin/utlsampl.sql .
重命名文件爲scott.sql：
[oracle@localhost ~]$ mv utlsampl.sql scott.sql
修改scott.sql：
主要是將scott用戶相關的語句改爲c##scott，刪除最後的EXIT，修改完的scott.sql如下：
scott.sql
SET TERMOUT OFF
SET ECHO OFF
DROP USER C##SCOTT CASCADE;
create user c##scott identified by tiger;
grant connect,resource,unlimited tablespace to c##scott container=all;
alter user c##scott default tablespace users;
alter user c##scott temporary tablespace temp;
CONNECT C##SCOTT/tiger
