What is your Oracle version?
With certain versions, you can use RMAN to do cross-platform migration.
If the volume of data is small, simple export import will do.

Easiest option is to export from 10g windows database and import into the 10g linux database.
If you are time pressed or would be doing it multiple times,
look into (google/search) "RMAN cross platform migration".

I am not familiar with Rman process and hence doing with export and import using data pump.

Following are the steps I am implementing and suggest if I need to execute any script to verify etc.
1. Complete export of the source database from Windows m/c using expdp
2. Creating the tablesspaces on target database i.e. on Linux
3. Import the data using impdp

But, while creating the tablespaces, after adding few datafiles by linux database is responding very slow. Any suggestions to improve the performance.

Thanks
Satya

With the information provided, it is black box for us also.
We have no idea on what is happening.
May be your "server" is slow.
May be your "disks" are bad. It could be anything.
Post some valuable information to start with. Someone might help.

in case this might apply....
From Note:119119.1

IMPORTANT:

* For the moment, do NOT use Expdp/Impdp when going to UTF8 or a other multibyte
characterset on ALL 10g versions including 10.1.0.5 and 10.2.0.3.
Also 11.1.0.6 is affected.
It will provoke data corruption unless you applied Patch 5874989!
This is caused by the impdp Bug 5874989.
The "old" exp/imp work fine. This problem is fixed in the upcoming
10.2.0.4 and 11.1.0.7 patch set.

All existing patches for this bug are found here:
http://updates.oracle.com/download/5874989.html

For 10.1.0.5, 10.2.0.2, 10.2.0.3 and 11.1.0.6 you can ask a backport
for Bug 5874989 if there is not yet a patch for your version/platform
