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 . Here we’re transporting a tablespace named “PERFSTAT” Step 1 : For a tablespace to be transportable it must be totally self contained. This can be checked using the DBMS_TTS.TRANSPORT_SET_CHECK procedure .
Some examples of self contained tablespace violations are:
• An index inside the set of tablespaces is for a table outside of the set of tablespaces. Note : It is not a violation if a corresponding index for a table is outside of the set of tablespaces
• A partitioned table is partially contained in the set of tablespaces. • A referential integrity constraint points to a table across a set boundary. • A table inside the set of tablespaces contains a LOB column that points to LOBs outside the set of tablespaces.
� Mandatory for a transport tablespace option :
• The source and target database must be on the same hardware platform. • The source and target database must use the same character set and national character set. • You cannot transport a tablespace to a target database in which a tablespace with the same name
already exists. • Transportable tablespaces do not support:
o Materialized views/replication o Function-based indexes o Scoped REFs o 8.0-compatible advanced queues with multiple recipients
Transport tablespace from one database to another By: Rahul Gupta [email protected] http://onlineerpdba.blogspot.com
SQL > EXECUTE dbms_tts.transport_set_check('PERFSTAT', TR UE); PL/SQL procedure successfully completed. SQL > SELECT * FROM TRANSPORT_SET_VIOLATIONS; no rows selected
The TRANSPORT_SET_VIOLATIONS view can be used to check for any violations:
Step 2 : Take the required tablespace in READ ONLY mode . It’s mandatory for transporting a tablespace that it should be in READ ONLY mode. If you’re database is in READ-ONLY mode and tablespace is in READ-WRITE . Then it wont work . SQL > alter tablespace PERFSTAT read only;
Step 3 : Export the PERFSTAT tablespace metadata using the export utility: exp transport_tablespace=y tablespaces=PERFSTAT fil e=/u43/oradata/stats_dump/perfdump.dmp log=/u43/oradata/stats_dump/perfdump.log [veritas:oraprod] /u43/oradata/stats_dump > erfdump .dmp log=/u43/oradata/stats_dump/perfdump.log < Export: Release 9.2.0.5.0 - Production on Sun Sep 1 3 10:38:57 2009 Copyright (c) 1982, 2002, Oracle Corporation.

Step 4 : Transport the Tablespace Set
Transport both the datafiles and the export file of the tablespaces to a place accessible to the target database. You can use any facility for copying flat files (for example, an operating system copy utility, ftp, or publishing on CDs).
scp /u24/oradata/ilproddata/perf01.dbf oraperf@192. 168.20.237:/perf/oradata/perfdata/ scp /u19/oradata/ilproddata/perf02.dbf oraperf@192. 168.20.237:/perf/oradata/perfdata/ scp /u32/oradata/ilproddata/perf0* [email protected]. 20.237:/perf/oradata/perfdata/ scp /u35/oradata/ilproddata/perf04.dbf oraperf@192. 168.20.237:/perf/oradata/perfdata/ scp /u40/oradata/ilproddata/perf0* [email protected]:/perf/oradata/perfdata/

Soltuion :
This is because of the tablespace in READ WRITE mode . Before taking the export of metadata, tablespace needs to be taken in READ ONLY mode Note: If your database is in READ ONLY mode and tablespace is in READ WRITE. In that case also,
you’ll get the same error.
