先说基本用法: 先按11G之前进行 conn / as sysdba; create user test identifed by test; ORA-65096: 公用用户名或角色名无效.

先说基本用法:

先按11G之前进行

conn / as sysdba;

create user test identifed by test;

ORA-65096: 公用用户名或角色名无效.

查官方文档得知“试图创建一个通用用户,必需要用C##或者c##开头”,,这时候心里会有疑问,什么是common user?不管先建成功了再说

create C##user test identifed by test;

创建成功

SQL>show con_name;

CON_NAME

CDB$ROOT

selectcon_id,dbid,NAME,OPEN_MODEfromv$pdbs;

SQL>alter session set container=PDBORCL;

这时再用create user test identifed by test;建立用户就可以了。

CDB和PDB是Oracle 12C一个很亮的新特性,由于他们的引入导致传统的ORACLE数据库管理理念不少发生了改变,这里列举了部分最基本的cdb和pdb管理方式
