1.表空间传输

1.1  传输表空间介绍

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(原库和目标库)

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.

 

 

 

 

 

 

 

 

 

 

 

 

 

1.8  将源库设置为只读模式

SQL> alter tablespace tps_hxl read only;

 

Tablespace altered.

 

 

1.9  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;

 

[oracle@localhost ~]$ expdp system/oracle dumpfile=expdat.dmp directory=datapump_dir transport_tablespaces=tps_hxl logfile=tts_export.log

1.9  转换

我这里两边的都是相同的操作系统，不需要进行转换，需要转换的化可以参考

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

1.10  使用ftp工具分别拷贝表空间和与表空间对应数据文件到相应的目录

导出的dump文件

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

表空间对应的数据文件

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

 

 

 

 

 

 

1.11 目标库手工调制文件目录

从库拷贝过来的数据文件目前是放在/u01/dumpdir/,我们需要放到pdbs所在的目录下

首先查看当前pdbs的数据文件路径

SQL> alter session set container=ORA12CPDB1;

SQL> set linesize 1000

SQL> column file_name format a64

SQL> column tablespace_name format a16

SQL> select file_name,tablespace_name from dba_data_files;

SQL> select file_name,tablespace_name from dba_data_files;

 

FILE_NAME                                                        TABLESPACE_NAME

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

/u01/app/oracle/oradata/ora12c/ora12cpdb1/system01.dbf           SYSTEM

/u01/app/oracle/oradata/ora12c/ora12cpdb1/sysaux01.dbf           SYSAUX

/u01/app/oracle/oradata/ora12c/ora12cpdb1/undotbs01.dbf          UNDOTBS1

/u01/app/oracle/oradata/ora12c/ora12cpdb1/users01.dbf            USERS

/u01/app/oracle/oradata/ora12c/ora12cpdb1/tps_goldengate01.dbf   TPS_GOLDENGATE

/u01/app/oracle/oradata/ora12c/ora12cpdb1/fda101.dbf             FDA1

 

6 rows selected.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

拷贝文件

[oracle@localhost dumpdir]$ cp /u01/dumpdir/tps_hxl01.dbf /u01/app/oracle/oradata/ora12c/ora12cpdb1/

 

 

 

 

 

 

1.12 目标库创建用户并进行导入

 

SQL> alter session set container=ORA12CPDB1;

Session altered.

SQL> create user hxl identified by oracle;

User created.

SQL> grant connect ,resource to hxl;

Grant succeeded.

 

 

 

 

 

 

 

 

 

 

 

 

导入:

[oracle@localhost dumpdir]$ impdp system/oracle@ORA12CPDB1 dumpfile=expdat.dmp directory=datapump_dir transport_datafiles=/u01/app/oracle/oradata/ora12c/ora12cpdb1/tps_hxl01.dbf remap_schema=hxl:hxl logfile=import.log

1.13 目标库验证

数据验证

SQL> select count(1) from hxl.tb_test01;

 

  COUNT(1)

----------

790000

修改用户的默认表空间

SQL> alter user hxl default tablespace tps_hxl;

 

 

 

 

 

1.14 修改表空间为可读

目标库导入完成后，相应的表空间是只读的，修改为可读写

目标端：

SQL> select tablespace_name,status from dba_tablespaces where tablespace_name='TPS_HXL';

 

TABLESPACE_NAME  STATUS

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

TPS_HXL          READ ONLY

 

alter tablespace tps_hxl read write;

 

目标端:

alter tablespace tps_hxl read write;
