Oracle 创建PDB的几种常用方法

news2024/11/23 21:57:10

PDB是运行在PDB上的一个数据库,各个PDB是独立运行的。在CDB中创建、删除、迁移PDB是非常方便的事情。不会对其它CDB和PDB产生任何影响。

CREATE PDB METHOD

创建PDB的简要说明

  • 利用Seed(种子)模板来创建

默认方法,使用PDB Seed或应用程序的模板文件夹创建PDB。将模板复制到一个新的目录,并将新的文件与新的PDB进行关联。

  • 复制已有的PDB/Non-CDB

通过复制PDB或Non-CDB来创建PDB。源库可以是本地CDB中的PDB、远端CDB中的PDB、本地或远端应用程序容器中的PDB、Non-CDB 。此方法将源端相关的文件复制到新的目录,然后与新的PDB进行关联。

  • 将PDB迁移到另一个CDB

通过将PDB从一个CDB中迁移到另一个CDB中来进行创建新的PDB。此方法将与PDB相关的文件移动到一个新的目录,而不是复制

  • 将Unplug的PDB插入到CDB中

通过使用PDB的XML元数据文件夹来创建PDB,并将其插到CDB中。XML文件中记录了PDB的详细配置信息。

  • 从Non-CDB创建PDB,并插入到CDB中

利用DBMS_PDB包将Non-CDB创建为PDB并插到CDB中。

CREATE PDB Condition

  • CDB必须存在且处于读写模式
  • 当前用户必须是公告用户,并且当前的容器必须是CDB root或应用程序容器。
  • 当前用户必须有CREATE PLUGGABLED DATABASE权限
  • PDB名称不能和已存在的PDB名称重复
  • 其它额外限制。比如DataGuard环境下创建PDB,必须进行更多额外的设置。

Use Seed template to Create PDB

COPY PDB

复制PDB就是用已经存在的数据库作为模板创建一个结构和数据(可以不复制数据)相同的PDB。复制期间如果想要保持源数据库正常运行,则源数据库必须处于归档模式且本地UNDO模式。

  • Local PDB
  • Remote PDB
  • Non-CDB

1.使用CREATE PLUGGABLE DATABASE 命令创建PDB

CREATE PLUGGABLE DATABASE pdb2 from pdb1
FILE_NAME_CONVERT = ('/u02/oradata/CDB1/pdb1','/u02/oradata/CDB1/pdb2');

Note:若CDB没有启动local UNDO模式,则源PDB必须以只读模式打开。
         若CDB是本地UNDO模式,则可以以读写模式打开。

        若没有启用OMF,则需要指定FILE_NAME_CONVERT参数。

如何打开读写模式:

SQL> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB1                           READ WRITE NO
         4 PDB2                           MOUNTED
         5 CNDBAPDB                       MOUNTED
SQL> alter pluggable database CNDBAPDB open;

Pluggable database altered.

SQL> show pdbs;

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
         2 PDB$SEED                       READ ONLY  NO
         3 PDB1                           READ WRITE NO
         4 PDB2                           MOUNTED
         5 CNDBAPDB                       READ WRITE NO
SQL>

如何启用OMF:

Enable Oracle Managed File (OMF) to simplify the creation of databases and database files.

SQL> ALTER SYSTEM SET DB_CREATE_FILE_DEST='/u02/oradata' SCOPE=BOTH;

System altered.

 Enable autostart of Pluggable databases with startup of Container Database.

SQL> ALTER PLUGGABLE DATABASE PDB1 SAVE STATE;

Pluggable database altered.

如果不想复制源PDB中表的数据,又想限制PDB可使用的总空间大小,则可以使用如下语句:

SQL> CREATE PLUGGABLE DATABASE cndbapdb2 from cndbapdb
  2  FILE_NAME_CONVERT = ('/u02/oradata/CDB1/cndbapdb/', '/u02/oradata/CDB1/cndbapdb2/')
  3    STORAGE (MAXSIZE 2G)
  4    NO DATA;

Pluggable database created.

2.利用Local PDB 快照创建PDB

1.手动创建快照

确认SNAPSHOT模式为MANUAL,语句如下:

SQL> set pagesize 200
SQL> set linesize 200
SQL> select PDB_NAME,snapshot_mode "s_mode",snapshot_interval/60 "snap_int_hrs" from DBA_PDBS;

PDB_NAME                                                                                                                         s_mode snap_int_hrs
-------------------------------------------------------------------------------------------------------------------------------- ------ ------------

PDB2                                                                                                                             MANUAL

复制remote PDB

如果复制的是远端的PDB,则必须使用DBLINK来复制,并且DBLINK是存在于本地CDB中的,而不是存在于远端CDB中的。

1.复制远端PDB的必要条件

(1) 当前操作用户必须具有CREATE PLUGGABLE DATABASE 的系统权限。

(2)源端和目标端都必须满足:

  • 同样的字节存储顺序(Endian)
  • 源端平台上安装的数据库组件必须和目标端平台上安装的数据库组件是一样的,或者是其子集。

4.操作示例

(1) 在主库、备库的CDB中执行如下命令,创建相同的共有用户及密码:

SQL> show user;
USER is "SYS"
SQL> create user c##maxwell identified by oracle;

User created.

SQL> grant create session,resource,create any table,unlimited tablespace to c##maxwell container=all;

Grant succeeded.

SQL> grant create pluggable database to c##maxwell container=all;

Grant succeeded.

SQL> grant sysoper to c##maxwell container=all;

Grant succeeded.

SQL> 

sys@cdb$root:orclcdb> show user
USER is "SYS"
sys@cdb$root:orclcdb> 
sys@cdb$root:orclcdb> 
sys@cdb$root:orclcdb> create user c##maxwell identified by oracle;

User created.

sys@cdb$root:orclcdb> grant create session,resource,create any table,unlimited tablespace to c##maxwell container=all;

Grant succeeded.

sys@cdb$root:orclcdb> grant create pluggable database to c##maxwell container=all;

Grant succeeded.

sys@cdb$root:orclcdb> grant sysoper to c##maxwell container=all;

Grant succeeded.

sys@cdb$root:orclcdb> 

(2) 由于源端不是本地UNDO模式,因此需要以只读模式打开,代码如下:
