在Oracle SQL Developer中，试图创建RD用户时，出现了如下的错误： 

在行: 6 上开始执行命令时出错 -
create user RD identified by 508
错误报告 -
SQL 错误: ORA-65096: 公用用户名或角色名无效
65096. 00000 -  "invalid common user or role name"
*Cause:    An attempt was made to create a common user or role with a name
           that was 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.

 

解决办法：

　　在执行下列命令之后，再执行你需要的操作：

　　　　SQL>show con_name;

　　　　SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;

　　　　SQL> alter session set container=ORCLE;

　　　　SQL> startup

其中container的内容，建议不要使用OPEN_MODE是READ ONLY的，不然相当于只进行了默认的操作。同时，alter session set container的方式只是局部范围中能用，比如此次cmd的界面中，如果切换回Oracle SQL Developer中，是不起效果的，如下举一个例子：创建一个不带C##开头的用户stest，效果是这样的，说明刚才在cmd中的操作暂时没有在

Oracle SQL Developer中起效。
