If you mean duplicate a tablespace into another database, have a look at transportable tablespace.

Database Administrator's Guide
Chapter 8 Managing Tablespaces
Section Transporting Tablespaces Between Databases

Thanks Michel.

If there is 100 tables in that tabelspace then do we need to execute
alter table 100 times?

Thanks.

First identify the segments that are in the tablespace, then you can use:

alter table <table_name> move tablespace <new_tablespace>

and

alter index <index_name> rebuild tablespace <new_tablespace>

You can write a script to simplify the task.

Thanks all for your informations.
I think this is the only way to move objects from one tablespace to another tablespace.

Thanks.

Please clarify my doubt.

If I go for transport tablespace then I have to have datapump utily installed along with oracle s/w.
Hope data pump is one part of oracle s/w

Thanks.
