篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了表空间传输-例子2(full transportable)相关的知识，希望对你有一定的参考价值。

环境:

原库

目的库

Db版本

11.2.0.4

192.168.1.85

12.2.0.1

新创建pdb为: ORA12CPDB2

192.168.1.134

1.1 表空间传输介绍

数据库表空间无论是字典管理还是手动管理，亦或者是目标端跟源端数据库大小不一致，都可以使用传输表空间，而且，相对来说，传输表空间要比使用数据泵导入导出迁移数据要快，这是因为传输表空间，是只把实际物理数据文件复制到指定的目标端位置，再灌入元数据，而数据泵导入导出则是需要把数据库对象按要求导出，然后目标端导入.

1.2 检查字节顺序

原库(11g)

SQL> set linesize 1000

SQL> column PLATFORM_NAME format a64

SQL> column ENDIAN_FORMAT format a16

SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT

2 FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d

3 WHERE tp.PLATFORM_ID = d.PLATFORM_ID;

PLATFORM_NAME ENDIAN_FORMAT

---------------------------------------------------------------- ----------------

Linux x86 64-bit Little

目的库(12c pdb)

SQL> set linesize 1000

SQL> column PLATFORM_NAME format a64

SQL> column ENDIAN_FORMAT format a16

SQL> SELECT d.PLATFORM_NAME, ENDIAN_FORMAT

2 FROM V$TRANSPORTABLE_PLATFORM tp, V$DATABASE d

3 WHERE tp.PLATFORM_ID = d.PLATFORM_ID;

PLATFORM_NAME ENDIAN_FORMAT

---------------------------------------------------------------- ----------------

Linux x86 64-bit Little

这里的字节顺序一致不需要转换

1.3 检查字符集

原库:

SQL> select userenv(‘language‘) from dual;

USERENV(‘LANGUAGE‘)

----------------------------------------------------

AMERICAN_AMERICA.ZHS16GBK

目的库:

SQL> select userenv(‘language‘) from dual;

USERENV(‘LANGUAGE‘)

----------------------------------------------------

AMERICAN_AMERICA.ZHS16GBK

1.4 检查Compatible参数

原库:

SQL> show parameter compatible

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

compatible string 11.2.0.4.0

目的库:

SQL> show parameter compatible

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

compatible string 12.2.0

1.5 源端创建表空间(用户、表以及测试数据)

查看当前的数据文件分布

SQL> column file_name format a64

SQL> column tablespace_name format a16

SQL> select file_name,tablespace_name from dba_data_files;

FILE_NAME TABLESPACE_NAME

---------------------------------------------------------------- ----------------

/u01/app/oracle/oradata/slnngkdg/users01.dbf USERS

/u01/app/oracle/oradata/slnngkdg/undotbs01.dbf UNDOTBS1

/u01/app/oracle/oradata/slnngkdg/sysaux01.dbf SYSAUX

/u01/app/oracle/oradata/slnngkdg/system01.dbf SYSTEM

/u01/app/oracle/oradata/slnngkdg/tps_goldengate01.dbf TPS_GOLDENGATE

SQL> connect / as sysdba

Connected.

SQL> create tablespace tps_hxl datafile ‘/u01/app/oracle/oradata/slnngkdg/tps_hxl01.dbf‘ size 100m autoextend on;

SQL> create user hxl identified by oracle default tablespace tps_hxl account unlock;

SQL> grant resource,connect to hxl;

SQL> connect hxl/oracle

Connected.

SQL> create table tb_test01 as select * from hxl01.tb_test01; ##(这里hxl需要有访问该表权限)

Table created.

SQL> select count(1) from tb_test01;

COUNT(1)

----------

790000

1.6 源端表空间自包含(独立性)检查

SQL> connect / as sysdba

Connected.

SQL> EXEC DBMS_TTS.TRANSPORT_SET_CHECK(‘TPS_HXL‘,TRUE,TRUE);

PL/SQL procedure successfully completed.

SQL> select * from transport_set_violations;

no rows selected

查询无返回结果说明检查通过，否则需要根据violation字段的说明解决各类参照完整性问题，比如说主键、外键约束、分区等问题，一般这些问题是指对象不在同一表空间.

1.7 创建目录原库

源库:

Os创建目录

mkdir -p /u01/dumpdir

SQL> connect / as sysdba

Connected.

SQL> create directory datapump_dir as ‘/u01/dumpdir‘;

Directory created.

目的pdb下创建

Os创建目录

mkdir -p /u01/dumpdir

SQL> connect / as sysdba

Connected.

SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED

---------- ------------------------------ ---------- ----------

2 PDB$SEED READ ONLY NO

3 ORA12CPDB1 READ WRITE NO

SQL> alter session set container=ORA12CPDB1;

Session altered.

SQL> create directory datapump_dir as ‘/u01/dumpdir‘;

Directory created.

1.7 将原库的用户自定义表空间都设置为只读模式

alter tablespace users read only;

alter tablespace tps_goldengate read only;

alter tablespace tps_hxl read only;

1.8 源端数据泵导出表空间元数据

目前授权给导出的用户,我们这里使用system导出

connect / as sysdba

grant write,read on directory datapump_dir to system;

因为我这里原库是11G的，导入到12C 需要指定version=12参数

expdp system/oracle full=y transportable=always directory=datapump_dir dumpfile=full_tts.dmp metrics=y exclude=statistics logfile=full_tts_export.log version=12

最后会出现如下的提示

Master table "SYSTEM"."SYS_EXPORT_FULL_01" successfully loaded/unloaded

******************************************************************************

Dump file set for SYSTEM.SYS_EXPORT_FULL_01 is:

/u01/dumpdir/full_tts.dmp

******************************************************************************

Datafiles required for transportable tablespace TPS_GOLDENGATE:

/u01/app/oracle/oradata/slnngkdg/tps_goldengate01.dbf

Datafiles required for transportable tablespace TPS_HXL:

/u01/app/oracle/oradata/slnngkdg/tps_hxl01.dbf

Datafiles required for transportable tablespace USERS:

/u01/app/oracle/oradata/slnngkdg/users01.dbf

Job "SYSTEM"."SYS_EXPORT_FULL_01" successfully completed at Wed Feb 19 14:36:41 2020 elapsed 0 00:05:30

1.9 原库进行文件转换

需要转换的化可以参考

https://www.cnblogs.com/hxlasky/p/12334747.html

1.10 将表空间数据文件和dump文件拷贝到目的库

scp /u01/dumpdir/full_tts.dmp oracle@192.168.1.134:/u01/dumpdir/

scp /u01/app/oracle/oradata/slnngkdg/users01.dbf oracle@192.168.1.134:/u01/dumpdir/

scp /u01/app/oracle/oradata/slnngkdg/tps_goldengate01.dbf oracle@192.168.1.134:/u01/dumpdir/

scp /u01/app/oracle/oradata/slnngkdg/tps_hxl01.dbf oracle@192.168.1.134:/u01/dumpdir/

数据文件传输完成到了目的库之后，原来的表空间可以设置为可读写了

alter tablespace users read write;

alter tablespace tps_goldengate read write;

alter tablespace tps_hxl read write;

1.11 目标库创建pdb

create pluggable database ora12cpdb2

admin user hxl01 identified by oracle

file_name_convert = (‘/u01/app/oracle/oradata/ora12c/pdbseed‘, ‘/u01/app/oracle/oradata/ora12c/ora12cpdb2‘);

alter pluggable database ORA12CPDB2 open;

1.12 数据文件拷贝到相应的目录下

将源库拷贝过来的数据文件拷贝到pdb实例所在的数据文件目录下面

cp /u01/dumpdir/tps_goldengate01.dbf /u01/app/oracle/oradata/ora12c/ora12cpdb2/

cp /u01/dumpdir/tps_hxl01.dbf /u01/app/oracle/oradata/ora12c/ora12cpdb2/

cp /u01/dumpdir/users01.dbf /u01/app/oracle/oradata/ora12c/ora12cpdb2/

1.13 目标库创建目录

目的pdb下创建

Os创建目录

mkdir -p /u01/dumpdir

SQL> connect / as sysdba

Connected.

SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED

---------- ------------------------------ ---------- ----------

2 PDB$SEED READ ONLY NO

3 ORA12CPDB1 READ WRITE NO

SQL> alter session set container=ORA12CPDB2

Session altered.

SQL> create directory datapump_dir as ‘/u01/dumpdir‘;

Directory created.

1.14 目标库导入

impdp system/oracle@ORA12CPDB2 directory=datapump_dir dumpfile=full_tts.dmp logfile=full_tts_imp.log metrics=y transport_datafiles=‘/u01/app/oracle/oradata/ora12c/ora12cpdb2/users01.dbf‘,‘/u01/app/oracle/oradata/ora12c/ora12cpdb2/tps_hxl01.dbf‘,‘/u01/app/oracle/oradata/ora12c/ora12cpdb2/tps_goldengate01.dbf‘

@ORA12CPDB2 这里是连接pdb2的tns连接名

提示报错:

原因是我这里原来已经有该表空间了，修改如下:
