Transport Tablespaces in Oracle Database 11g


You can use the transportable tablespaces feature to move a subset of an Oracle Database and "plug" it in to another Oracle Database, essentially moving tablespaces between the databases. The tablespaces being transported can be either dictionary managed or locally managed. Starting with Oracle9i, the transported tablespaces are not required to be of the same block size as the target database standard block size.

In this article, I have shown how to accomplish the same. Please follow the below mentioned steps to get to know how to do it.

Step 1: Create a new tablespace, a separate user for that particular tablespace. Also providing some basic privileges to the new user.

SQL> select name from V$datafile;
NAME
--------------------------------------------------------------------------------
F:\DATABASE\ORADB11G\SYSTEM01.DBF
F:\DATABASE\ORADB11G\SYSAUX01.DBF
F:\DATABASE\ORADB11G\UNDOTBS01.DBF
F:\DATABASE\ORADB11G\USERS01.DBF
F:\DATABASE\ORADB11G\EXAMPLE01.DBF
SQL>
SQL> create tablespace TRANS_TAB datafile 'F:\DATABASE\ORADB11G\TRANSTAB01.DBF' size 1M autoextend on;
Tablespace created.
SQL> create user TEST_TAB identified by test default tablespace TRANS_TAB quota unlimited on TRANS_TAB;
User created.
SQL> grant create session, resource, create table to TEST_TAB;
Grant succeeded.

Step 2: Create a table and insert some values in that table. (This is not necessary but I want to store some data in the tablespace before transporting it to other database).

SQL> conn TEST_TAB@oradb11g
Enter password:
Connected.
SQL>
SQL> create table DEMO_TABLE(id number, description varchar2(20));
Table created.
 
insert into DEMO_TABLE values (1, 'qwerty');
insert into DEMO_TABLE values (2, 'qwerty1');
insert into DEMO_TABLE values (3, 'qwerty13');
insert into DEMO_TABLE values (4, 'qwerty132');
insert into DEMO_TABLE values (5, 'qwerty1324');
insert into DEMO_TABLE values (6, 'qwerty13245');
commit;
 
SQL> set lines 200
SQL> select * from DEMO_TABLE;
        ID DESCRIPTION
---------- --------------------
         1 qwerty
         2 qwerty1
         3 qwerty13
         4 qwerty132
         5 qwerty1324
         6 qwerty13245
6 rows selected.

Step 3: Before transporting the tablespace check for any violations because for a tablespace to be transportable, it must be totally self contained.

SQL> conn sys@oradb11g as sysdba
Enter password:
Connected.
SQL>
SQL> EXEC SYS.DBMS_TTS.TRANSPORT_SET_CHECK(ts_list => 'TRANS_TAB', incl_constraints => TRUE);
PL/SQL procedure successfully completed.
SQL> SELECT * FROM transport_set_violations;
no rows selected

Step 4: Creating the directory for Data Pump Export and putting the Tablespace in Read Only mode.

SQL> alter tablespace TRANS_TAB read only;
Tablespace altered.
SQL> create directory DB_DUMP as 'F:\Database\DUMP';
Directory created.

Step 5: Exporting the tablespace Metadata using EXPDP.

C:\Users\parain>expdp directory=DB_DUMP transport_tablespaces=TRANS_TAB dumpfile=trans_tab.dmp logfile=trans_tab.log

Job "SYSTEM"."SYS_EXPORT_TRANSPORTABLE_01" successfully completed at Thu May 10 17:22:35 2018 elapsed 0 00:00:28

Step 6: Before Putting the tablespace back again to Read Write Mode, copy the datafile of that tablespace to target database. OR if you copy the datafile after you put the tablespace in Read Write mode then you’ll be getting Oracle Error ORA-19722.

Step 7: Once datafile copying is done, put that Tablespace back in Read Write Mode.

C:\Users\parain>sqlplus sys@oradb11g as sysdba

SQL> alter tablespace TRANS_TAB read write;
Tablespace altered.

Step 8: Create the Data Pump Directory and New User (as created in the source database)

C:\Users\parain>sqlplus sys@oradb112 as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on Thu May 10 17:24:26 2018

SQL> create directory DB_DUMP as 'F:\Database\DUMP';
Directory created.
 
SQL> create user TEST_TAB identified by test;
User created.
SQL> grant create session, resource, create table to TEST_TAB;
Grant succeeded.

Step 9: Import the Tablespace Metadata and mention the copied datafile in the TRANSPORT_DATAFILE parameter.

C:\Users\parain>impdp directory=DB_DUMP dumpfile=TRANS_TAB.DMP logfile=impTRANSTAB.log transport_datafiles=
'F:\DATABASE\ORADB112\TRANSTAB01.DBF'

Master table "SYSTEM"."SYS_IMPORT_TRANSPORTABLE_01" successfully loaded/unloaded

Job "SYSTEM"."SYS_IMPORT_TRANSPORTABLE_01" successfully completed at Thu May 10 17:40:09 2018 elapsed 0 00:00:02

Step 10: Check for the Tablespace Entry in the DBA_TABLESPACES view and change it’s status to Read Write Mode.

I hope this helps !!
