This post will be about Cross-platform transportable tablespace. Cross-platform transportable tablespace is a technique where you can copy a tablespace from a database running in one platform to another platform. Also Cross-platform transportable tablespace isn’t the same as Cross-platform transportable database. In this instance the whole database is copied including the SYSTEM tablespace. In this post we are going to copy a tablespace from one database to another database. Then the first thing you have to know is the internal names for each platform that supports cross-platform data transport and this information is found in V$TRANSPORTABLE_PLATFORM view as below:
SQL> select PLATFORM_ID, PLATFORM_NAME, ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM;
PLATFORM_ID PLATFORM_NAME ENDIAN_FORMAT
----------- ----------------------------------------------------------------------------------------------------- --------------
1 Solaris[tm] OE (32-bit) Big
2 Solaris[tm] OE (64-bit) Big
7 Microsoft Windows IA (32-bit) Little
10 Linux IA (32-bit) Little
6 AIX-Based Systems (64-bit) Big
3 HP-UX (64-bit) Big
5 HP Tru64 UNIX Little
4 HP-UX IA (64-bit) Big
11 Linux IA (64-bit) Little
15 HP Open VMS Little
8 Microsoft Windows IA (64-bit) Little
9 IBM zSeries Based Linux Big
13 Linux x86 64-bit Little
16 Apple Mac OS Big
12 Microsoft Windows x86 64-bit Little
17 Solaris Operating System (x86) Little
18 IBM Power Based Linux Big
19 HP IA Open VMS Little
20 Solaris Operating System (x86-64) Little
21 Apple Mac OS (x86-64) Little
20 rows selected.
After you will need to run the SQL below to get the platform name of your current source server and later this information will be used to convert the files of the tablespace afterwards. In this post the source will have the platform from ‘Solaris Operating System (x86-64)’ as you can see:
SQL> SELECT PLATFORM_NAME
FROM V$TRANSPORTABLE_PLATFORM
WHERE PLATFORM_ID =
( SELECT PLATFORM_ID FROM V$DATABASE ); 2 3 4
PLATFORM_NAME

Solaris Operating System (x86-64)
Place the tablespaces to be transported in read-only mode as below:
Command: alter tablespace <tablespace name> read only; SQL> alter tablespace TBS_DATABASKET read only; Tablespace altered.
Create the directory where the dump will be generated:
SQL> CREATE OR REPLACE DIRECTORY TBSTECHDIR AS '/datapump/tbs/'; Directory created. SQL> grant read, write on directory TBSTECHDIR to public;
Ok, now we have all the information that we need to perform the export of the tablespace and create the dump and all required datafiles to perform the transport of the tablespace TBS_DATABASKET running on the Solaris Operating System (x86-64) to a Linux x86 64-bit system. So I have executed this command:
expdp br/br@dbtech directory=TBSTECHDIR transport_tablespaces=TBS_DATABASKET
Following by the output:

So I copied the datafile and the dump to the directory /techdatabask02/server02/tbs in the target server:
Datafile: /u01/app/oracle/oradata/PROD/tbstechdata01.dbf Dump: /datapump/tbs/TBSTECHDIRBR.dmp Directory in the target server: /techdatabask02/server02/tbs
Now I am going to connect to the database PRDTECH and convert the datafile:

Let’s import the tablespace TBS_DATABASKET into the PRDTECH database:
- Change the and with the right values.
impdp <user>/<password> dumpfile=TBSTECHDIRBR.dmp directory=TBSTECHDIR transport_datafiles=/u01/app/oracle/oradata/PROD/tbstechdata01.dbf
The output:

Change the status of the new tablespace in the new database:
