Oracle 12C CDB、PDB常用管理命令


--查看PDB信息（在CDB模式下）

show pdbs  --查看所有pdb
select name,open_mode from v$pdbs;  --v$pdbs为PDB信息视图
select con_id, dbid, guid, name , open_mode from v$pdbs;

--切换容器

alter session set container=orcl1  --切换到PDBorcl1容器
alter session set container=CDB$ROOT    --切换到CDB容器

--查看当前属于哪个容器

select sys_context('USERENV','CON_NAME') from dual; --使用sys_context查看属于哪个容器
show con_name  --用show查看当前属于哪个容器

--创建pdb

create pluggable database pdb1 admin user pdb1admin identified by pdb1admin create_file_dest='+PDBDATA';

--启动PDB

alter pluggable database orcl1 open;    --开启指定PDB
alter pluggable database all open;  --开启所有PDB
alter session set container=orcl1;  --切换到PDB进去开启数据库
startup

--关闭PDB

alter pluggable database orcl1 close;      --关闭指定的PDB
alter pluggable database all close;    --关闭所有PDB
alter session set container=orcl1;  --切换到PDB进去关闭数据库
shutdown immediate

--创建或克隆前要指定文件映射的位置（需要CBD下sysdba权限）

alter system set db_create_file_dest='/u01/app/oracle/oradata/orcl/orcl2';

--创建一个新的PDB：（需要CBD下sysdba权限）

create pluggable database test admin user admin identified by admin;   
alter pluggable database test_pdb open;    --将test_pdb 打开

--克隆PDB（需要CBD下sysdba权限）

create pluggable database orcl2 from orcl1;  --test_pdb必须是打开的，才可以被打开
alter pluggable database orcl2 open;  --然后打开这个pdb

--删除PDB（需要CBD下sysdba权限）

alter pluggable database  orcl2 close;  --关闭之后才能删除
drop pluggable database orcl2 including datafiles;  --删除PDB orcl2

--设置CDB启动PDB自动启动（在这里使用的是触发器）

CREATE OR REPLACE TRIGGER open_pdbs
AFTER STARTUP ON DATABASE
BEGIN
EXECUTE IMMEDIATE 'ALTER PLUGGABLE DATABASE ALL OPEN';
END open_pdbs;

1 第一种方式设置自动启动方式

SQL> create pluggable database orcl admin user oper identified by "ora#123" file_name_convert=('SEEDDB','ORCL/DATAFILE','seeddb','orcl/datafile');  ###创建orcl pdb数据库

Pluggable database created.

SQL> alter pluggable database orcl open;  --打开pdb数据库

Pluggable database altered.

SQL> alter pluggable database orcl save state;   --设置pdb保存

####集群环境下制定instances

alter pluggable database all close immediate instances=all;

alter pluggable database all open read only instances=all;

alter pluggable database all save state instances=all;


2 第2种方式使用trigger的方式；

SQL>alter session set container=CDB$ROOT;

Session altered.

CREATE OR REPLACE TRIGGER open_pdbs
AFTER STARTUP ON DATABASE
BEGIN
  EXECUTE IMMEDIATE 'ALTER PLUGGABLE DATABASE ALL OPEN';
END open_pdbs;

3 打开所有pdb

alter pluggable database all open；

CDB的打开和关闭和以前的非CDB环境一致,可以打开带nomount,mount,open


PDB可以打开到mount,migrate,read only,read write,注意PDB不能打开到nomount

3 关闭pdb
alter pluggable database all close immediate ;

alter pluggable database orcl open;
alter pluggable database orcl open read only;
alter pluggable database orcl open upgrade restricted;
alter pluggable database orcl close;
alter pluggable database orcl close immediate;
alter pluggable database all except orcl open;
alter pluggable database all except orcl1,orcl2 close;
alter pluggable database all except orcl1,orcl2 close;
