    安装了12c版本,发现没有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。

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:

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。Oracle 12C引入了CDB与PDB的新特性,在ORACLE 12C数据库引入的多租用户环境(Multitenant Environment)中,允许一个数据库容器(CDB)承载多个可插拔数据库(PDB)CDB全称为Container Database,中文翻译为数据库容器,PDB全称为Pluggable Database,即可插拔数据库。在ORACLE 12C之前,实例与数据库是一对一或多对一关系(RAC):即一个实例只能与一个数据库相关联,数据库可以被多个实例所加载。而实例与数据库不可能是一对多的关系。当进入ORACLE 12C后,实例与数据库可以是一对多的关系。下面是官方文档关于CDB与PDB的关系图。

查看错误ORA--65096:(oracle自带错误查找工具:!oerr ora 65096[错误代码])

    特别注意:

    该工具位于$ORACLE_HOME/bin/oerr
    该工具所调用的错误信息列表文件为 $ORACLE_HOME/rdbms/mesg/oraus.msg
    该工具不可用于windows上,经测试,9i,10g,11g,12c都有此工具。

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。

创建scott用户和表的sql文件在oracle的安装目录下:

    D:\app\oracle\product\12.1.0\dbhome_1\RDBMS\ADMIN\utlsampl.sql

复制一个副本到当前目录,重命名为create.sql

修改create.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:

create.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

测试:

sqlplus / as sysdba
SQL> @d:\create.sql;
SQL> conn c##scott/tiger

SQL> select table_name from user_tables;
 
SQL> select * from SALGRADE;

scott用户和表创建完成。
