--通过con_name能看到当前登录的环境是CDB根库,CDB包含一个名为PDBORCL的可插拔库。

SQL> show con_name pdbs;

CON_NAME

CDB$ROOT

CON_ID CON_NAME OPEN MODE RESTRICTED

2 PDB$SEED READ ONLY NO

3 PDBORCL MOUNTED

--创建公用用户admin，需要使用C##或者c##作为该用户名的开头。

SQL> create user C##admin identified by Lxf$txx282534;

User created.

--如果使用普通方法创建会报错

SQL> create user admin identified by Lxf$txx282534;

create user admin identified by Lxf$txx282534

ERROR at line 1:

ORA-65096: invalid common user or role name

--创建公用角色， 同公用用户一样也需要使用C##或者c##作为角色名的开头。

SQL> create role C##admin01 container=all;

Role created.

--将dba角色授予公用角色, 适用范围为所有PDB

SQL> grant dba to c##admin01 container=all;

Grant succeeded.

--将公用角色授予公用用户， 使用范围为所有PDB

SQL> grant C##admin01 to C##admin container=all;

Grant succeeded.

--下面使用公用用户分别登录CDB、PDB看看是否通用。

今天发现重新开机后想直接登陆PDB容器的用户是做不到的，会出现以下报错

[oracle@oracle ~]$ sqlplus C##admin/'Lxf$txx282534'@pbdorcl

ERROR:

但是能正常登陆CDB容器的数据库

[oracle@oracle ~]$ sqlplus C##admin/'Lxf$txx282534'
