创建多容器、多实例、多租户、可插拔数据库（CDB、PDB）

1.通过DBCA图形化界面

$ dbca

打开DBCA图形化界面

 

 

 

 

 

 

 

 

 此选项卡全部默认即可

 

 

 

 

 等待安装完成即可

 2.SQL*PLUS

 $ mkdir /u01/app/oracle/oradata/CBD3/seed -p

 $ mkdir /u01/app/oracle/fast_recovery_area/CDB3

 $ cd /u01/app/oracle/admin ;mkdir cdb3 ;cd cdb3

 $ mkdir adump bdump cdump pfile udump

 $ cd /u01/app/oracle/product/18c/dbs ;cp initorcl.ora initcdb3.ora

 $ vi initcdb3.ora

 使用文本替换功能替换文中的orcl为cdb3

 首先切换到命令模式，然后输入

:%s/orcl/cdb3/g

 $ . oraenv
ORACLE_SID = [orcl] ? cdb3
ORACLE_HOME = [/home/oracle] ? /u01/app/oracle/product/18c
The Oracle base remains unchanged with value /u01/app/oracle
