12c可插拔数据库CDB与PDB管理总结

创建pdb
1、直接创建

1 CREATE PLUGGABLE DATABASE pdb2
2 ADMIN USER boswll IDENTIFIED BY oracle
3 STORAGE (MAXSIZE 2G MAX_SHARED_TEMP_SIZE 100M)
4 DEFAULT TABLESPACE test DATAFILE '/opt/oracle/oradata/orcl/datafile/test_001.dbf' SIZE 25M AUTOEXTEND ON;

2、以现有pdb为模板创建
现有pdb必须在read only模式下才能被创建,否则报错
以pdb1为模板创建pdb2

1 alter pluggable database pdb2 close immediate;
2 drop pluggable database pdb2 including datafiles;
3 alter pluggable database pdb1 close;
4 alter pluggable database pdb1 open read only;
5 create pluggable database pdb2 
6 from pdb1 
7 file_name_convert =('/opt/oracle/oradata/orcl/E98BEB85B1A80C56E0439A02A8C05841/datafile/','/opt/oracle/oradata/orcl/datafile/pdb2');

打开关闭pdb

1 alter pluggable database all open; 
2 alter pluggable database pdb2 close;
3 alter pluggable database all close;
4 alter pluggable database pdb2 close immediate;
5 alter pluggable database pdb2 open;
6 alter pluggable database all open;

删除pdb
与删除表空间类似,可以级联删除数据文件

1 drop pluggable database pdb2;
2 drop pluggable database pdb2 including datafiles;

只是删除库,不删除文件

1 DROP PLUGGABLE DATABASE pdb2 KEEP DATAFILES; 
 1 保持启动CDB后PDB的状态
 2 alter pluggable database all save state;
 3 shut immediate;
 4 startup
 5 
 6 容器之间的切换
 7 alter session set container=CDB$ROOT;
 8 alter session set container=pdb5;
 9   
10 查看当前容器
11 show con_name
12 select sys_context('userenv', 'con_name') "Container DB" from dual;
13 
14 查看pdb的信息
15 查看CDB中有多少个pluggable database
16 alter session set container=CDB$ROOT;
17 show pdbs
18 select con_id, dbid, guid, name , open_mode from v$pdbs;
