Oracle18c创建不带C##的用户

18c数据库分两种数据库CDB(容器数据库)、PDB(可插拔数据库)

数据库安装完成之后,默认是CDB

创建一个用户,必须要用C##开头,但使用PDB没有这个限制 

1. 先查看PDB数据库service

[root@Oracle ~]# lsnrctl status

2. 修改tnsname.ora文件,添加一个pdb的记录,就可以连接pdb

[root@Oracle ~]# su oracle
[oracle@Oracle ~]$ vi /u01/app/oracle/product/18.3/db_1/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/18.3/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_CDB1 =
  (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle)(PORT = 1521))


CDB1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cdb1)
    )
  )

cdb1pdb =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Oracle)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cdb1pdb)
    )
  )
  

3. 使用pdb登录

[oracle@Oracle ~]$ sqlplus system/manager@cdb1pdb
