--进入cdb 
sqlplus /nolog 
conn sys/sys as dba 

--查看数据库基本信息
select name,cdb from v$database;

--查看容器的相关信息
select con_id,name from v$containers;

--查看数据文件的路径
select con_id,file_name from cdb_data_files order by 1;

--显示当前连接容器信息
show con_id con_name user

--显示所有pdb
show pdbs

--start和stop根容器

--启动数据
--CDB
sqlplus / as sysdba
startup

--PDB(所有PDB)
alter pluggable database all open;
--启动pdb1库
alter pluggable database pdb1 open;

--关闭数据库
--CDB
shutdown immediate

--pdb1
alter pluggable database pdb1 close;
alter pluggable database pdb1 close immediate;
--关闭所有pdb
alter pluggable database all close immediate;

--创建公用用户(sys和system在可插拔中就是自动创建的公用用户)
sqlplus / as sysdba
create user c#dba identified by alex;

--创建公用角色
sqlplus / as sysdba
create role c##dbaprivs container=all;

grant dba to c##dbaprivs container=all;

--公用角色给公用用户
grant c##dbaprivs to c#dba container=all;

--切换容器
alter session set container=ehrpdb;
--切换回根容器
alter session set container=cdb$root;

--2创建可插拔数据库
--2.1克隆种子容器
create pluggable database cpcdb
admin user cpcadm identified by  cpcadm
file_name_convert=('/oracle/app/oracle/oradata/edw/pdbseed','/oradata/edw/cpcdb/datafile/');

--2.2直接创建数据库
CREATE PLUGGABLE DATABASE hrdb
ADMIN USER hrdba IDENTIFIED BY hrdba
STORAGE (MAXSIZE 100G MAX_SHARED_TEMP_SIZE 2G)
DEFAULT TABLESPACE hrdb DATAFILE '/oradata/EDW/hrdb/datafile/hrdb001.dbf' SIZE 512M AUTOEXTEND on next 8M maxsize 10G;

CREATE PLUGGABLE DATABASE cpcdb
ADMIN USER cpcdba IDENTIFIED BY cpcdba
STORAGE (MAXSIZE 100G MAX_SHARED_TEMP_SIZE 2G)
DEFAULT TABLESPACE tbscpc DATAFILE '/oradata/EDW/cpcdb/datafile/tbscpc001.dbf' SIZE 512M AUTOEXTEND on next 8M maxsize 10G;

--2.3创建数据案例

create pluggable database cpcdb
admin user cpcadm identified by  cpcadm
file_name_convert=('/oracle/app/oracle/oradata/edw/pdbseed','/oradata/edw/cpcdb/datafile/');

create pluggable database ncdb
admin user ncadm identified by  ncadm
file_name_convert=('/oradata/edw/pdbseed','/oradata/edw/ncdb/datafile/');

CREATE PLUGGABLE DATABASE ncdb
ADMIN USER ncdba IDENTIFIED BY ncdba
STORAGE (MAXSIZE 100G MAX_SHARED_TEMP_SIZE 2G);

--访问ncdb的插拔数据库
sqlplus sys/[email protected]:1521/ncdb as sysdba 

--关闭PDB数据库
alter pluggable database ncdb close immediate;
alter pluggable database hrdb close immediate;
alter pluggable database cpcdb close immediate;
alter pluggable database edwpdb close immediate;
--删除PDB数据库 
DROP PLUGGABLE DATABASE ncdb INCLUDING DATAFILES; 
DROP PLUGGABLE DATABASE hrdb INCLUDING DATAFILES; 
DROP PLUGGABLE DATABASE cpcdb INCLUDING DATAFILES;
DROP PLUGGABLE DATABASE edwpdb INCLUDING DATAFILES; 

--创建pdb案例
--1、cpcdb
create pluggable database cpcdb
admin user cpcadm identified by  cpcadm
file_name_convert=('/oradata/edw/pdbseed/','/oradata/edw/cpcdb/');

--2、ncdb
create pluggable database ncdb
admin user ncadm identified by  ncadm
file_name_convert=('/oradata/edw/pdbseed/','/oradata/edw/ncdb/');

--3、hrdb
create pluggable database hrdb
admin user hradm identified by hradm
file_name_convert=('/oradata/edw/pdbseed/','/oradata/edw/hrdb/');

alter pluggable database all open;

--登录cpcdb
$sqlplus sys/[email protected]:1531/cpcdb as sysdba

$sqlplus sys/[email protected]:1533/ncdb as sysdba --含有！需要单独输入密码
