12c可插拔 数据库CDB与pdb管理总结

-创建pdb

--1直接创建

CREATE PLUGGABLE DATABASE pdb2

ADMIN USER boswll IDENTIFIED BY oracle

STORAGE (MAXSIZE 2G MAX_SHARED_TEMP_SIZE 100M)

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

alter pluggable database pdb2 close immediate;

drop pluggable database pdb2 including datafiles;

alter pluggable database pdb1 close;

alter pluggable database pdb1 open read only;

create pluggable database pdb2

from pdb1

file_name_convert =('/opt/oracle/oradata/orcl/E98BEB85B1A80C56E0439A02A8C05841/datafile/','/opt/oracle/oradata/orcl/datafile/pdb2');

--打开关闭pdb

alter pluggable database all open;

alter pluggable database pdb2 close;

alter pluggable database all close;

alter pluggable database pdb2 close immediate;

alter pluggable database pdb2 open;

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

drop pluggable database pdb2;

drop pluggable database pdb2 including datafiles;

---只是删除库，不删除文件

DROP PLUGGABLE DATABASE pdb2 KEEP DATAFILES;

--unplug 数据库pdb

--unplug后pdb只能mount不能open

alter pluggable database pdb2 unplug into '/tmp/pdb2.xml';

--unplug后删除pdb，再使用xml文件加回pdb

drop pluggable database pdb2;

create pluggable database pdb2 using '/tmp/pdb2.xml' nocopy;

---插入数据库pdb

CREATE PLUGGABLE DATABASE pdb5 USING '/tmp/pdb2.xml' COPY FILE_NAME_CONVERT=('orcl/PDB2/ORCL/270349FEACBF115BE0530210A8C0B69A/datafile/o1_mf_sysaux_c72mqpft_.dbf','TEST/PDB5/sysaux.dbf','orcl/PDB2/ORCL/270349FEACBF115BE0530210A8C0B69A/datafile/o1_mf_system_c72mqpfl_.dbf','TEST/PDB2/system.dbf','orcl/PDB5/ORCL/270349FEACBF115BE0530210A8C0B69A/datafile/o1_mf_temp_c72mqpfw_.dbf','TEST/PDB5/temp.dbf')

静默方式创建pdb 数据库

dbca -silent -createDatabase -templateName $ORACLE_HOME/assistants/dbca/templates/General_Purpose.dbc -gdbname newtest -sid newtest -characterSet UTF8 -createAsContainerDatabase true -sysPassword oracle -systemPassword oracle

保持启动CDB后PDB的状态

alter pluggable database all save state;

shut immediate;

startup

--容器之间的切换

alter session set container=CDB$ROOT;

alter session set container=pdb5;

---查看当前容器

show con_name

select sys_context('userenv', 'con_name') "Container DB" from dual;

--查看pdb的信息

查看CDB中有多少个pluggable database

alter session set container=CDB$ROOT;

show pdbs

select con_id, dbid, guid, name , open_mode from v$pdbs;
