迁移表空间databump

使用databump导入导出，两个库用户必须一致，否则另一个库导入的时候会报错。所以两个库都是用helei用户。

给两个数据库的用户分别授予dba权限，这里只是实验更清晰而已。

SQL> create user helei identified by MANAGER;

User created.

SQL> grant connect,resource to helei;

Grant succeeded.

SQL>grant dba to helei;

Grantsucceeded.

我们先查看表空间，我们要把主机HE3中的heleitbs表空间空间迁移到HE4的数据库当中。

SQL>select TABLESPACE_NAME,STATUS from dba_tablespaces;

TABLESPACE_NAME               STATUS

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

SYSTEM                               ONLINE

SYSAUX                               ONLINE

UNDOTBS1                       ONLINE

TEMP                               ONLINE

USERS                               ONLINE

EXAMPLE                       ONLINE

6 rowsselected.

我们在HE3上的heleitbs表空间中创建一张表，所有的操作都用到helei用户

SQL>createtablespace heleitbs datafile ‘/u01/app/oracle/oradata/orcl/heleitbs1.dbf‘ size10m;

Tablespacecreated.

SQL> createtable TTT (a int,b varchar2(20));

Tablecreated.

SQL> alter table TTT add constraint TTT_PRIKEYprimary key (a);

insert into ttt values(1,‘helei1‘);

insert into ttt values(2,‘helei2‘);

SQL> commit;

Commit complete.

2.先在两个虚拟机上创建目录，并且授权

[[email protected]~]$ mkdir -p /home/oracle/dumpfile

[[email protected]~]$ chown -R oracle. dumpfile

[[email protected]~]$ chmod -R 755 dumpfile

在HE3数据库中给文件夹做授权

SQL>createdirectory dumpfile as ‘/home/oracle/dumpfile‘;

Directorycreated.

SQL> grant all on directory dumpfile to public;

Grantsucceeded.

在HE4数据库中给文件夹做授权

SQL>createdirectory dumpfile as ‘/home/oracle/dumpfile‘;

Directorycreated.

SQL> grant all on directory dumpfile to public;

Grantsucceeded.

3.在HE3库中，需要用sys登录，检查一下表空间里面的表是否可以迁移。

查询代码：

EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK(‘需要迁移的表空间名字‘, TRUE);

SELECT * FROM TRANSPORT_SET_VIOLATIONS;

SQL> conn / as sysdba

Connected.

SQL>show user

USER is"SYS"

SQL>EXECUTEDBMS_TTS.TRANSPORT_SET_CHECK(‘heleitbs‘,true);

PL/SQLprocedure successfully completed.

SQL> select * from transport_set_violations;

no rowsselected

4.在HE3库中，把heleitbs表空间变为只读。

SQL> conn / as sysdba

Connected.

SQL> alter tablespace heleitbs read only;

Tablespacealtered.

SQL>select TABLESPACE_NAME,STATUS from dba_tablespaces;

TABLESPACE_NAME               STATUS

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

SYSTEM                               ONLINE

SYSAUX                               ONLINE

UNDOTBS1                       ONLINE

TEMP                               ONLINE

USERS                               ONLINE

EXAMPLE                       ONLINE

HELEITBS                       READ ONLY

7 rowsselected.

5.使用databump导入导出把helei用户的heleitbs表空间导出到系统中的文件夹中。

[[email protected]]$expdp helei/MANAGERdumpfile=helei.dmp directory=dumpfile transport_tablespaces=heleitbs

6.用scp把HE3的dumpfile文件夹里面的helei.dmp拷贝到HE4的dumpfile文件夹中。

[[email protected]]$ scp -rp helei.dmpHE4:/home/oracle/dumpfile/

helei.dmp                                                                  100%   80KB  80.0KB/s

在HE4虚拟机里查看一下dumpfile文件夹有没有helei.dmp

[[email protected]~]$ cd dumpfile/

helei.dmp

7.分别查看weixiaobin库和ronger库的数据文件存在的位置。

HE3库

SQL>select name from v$datafile;

NAME

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

/u01/app/oracle/oradata/orcl/system01.dbf

/u01/app/oracle/oradata/orcl/sysaux01.dbf

/u01/app/oracle/oradata/orcl/undotbs01.dbf

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

/u01/app/oracle/oradata/orcl/example01.dbf

/u01/app/oracle/oradata/orcl/heleitbs1.dbf

6 rowsselected.

HE4库

SQL>select name from v$datafile;

NAME

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

/u01/app/oracle/oradata/orcl/system01.dbf

/u01/app/oracle/oradata/orcl/sysaux01.dbf

/u01/app/oracle/oradata/orcl/undotbs01.dbf

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

/u01/app/oracle/oradata/orcl/example01.dbf

8.把HE3库的数据文件heleitbs1.dbf拷贝到HE4库里的数据文件当中。

[[email protected]~]$cd /u01/app/oracle/oradata/orcl/

[[email protected]]$ scp heleitbs1.dbfHE4:/u01/app/oracle/oradata/orcl/

heleitbs1.dbf                                                              100%   10MB  10.0MB/s  00:00

然后查看一下HE4有没有heleitbs1.dbf文件

[[email protected]]$ cd /u01/app/oracle/oradata/orcl/

control01.ctl  example01.dbf redo01.log  redo03.log    system01.dbf  undotbs01.dbf

control02.ctl  heleitbs1.dbf redo02.log  sysaux01.dbf  temp01.dbf   users01.dbf

9.这时用使用databump导入导出把HE4的dumpfile文件家里面的helei.dmp导入到自己的数据库中

[[email protected]~]$impdp helei/MANAGERdumpfile=helei.dmp directory=dumpfile transport_datafiles=‘/u01/app/oracle/oradata/orcl/heleitbs1.dbf‘

Processingobject type TRANSPORTABLE_EXPORT/POST_INSTANCE/PLUGTS_BLK

Job"HELEI"."SYS_IMPORT_TRANSPORTABLE_01" successfullycompleted at 00:36:49

10.把两个库中的heleitbs表空间都设置为读写模式。

两个库命令是一致的使用dba用户和weixiaobin用户都可以

SQL> alter tablespace heleitbs read write;

Tablespacealtered.

11.验证，看看HE4虚拟数据中是不是HELEITBS表空间。看看表空间里有没有TTT的表

SQL> select TABLE_NAME,TABLESPACE_NAME fromdba_tables where TABLESPACE_NAME=‘HELEITBS‘;

TABLE_NAME                       TABLESPACE_NAME

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

TTT                               HELEITBS
