Server Utilities :: Export Data Using Expdp To Remote Host

I have to servers 'A' and 'B', On Server there is a schema with the name "test" having a table "t1". I want to import this t1 table to server B.

Is it possible to export dump using expdp to remote host.

I found that there is an option for this like "network_link". for testing this, I created a dblink from Server "B" to "A" named "vxmldb".

When I am using the below command on Server B there I am getting the following error.

C:>expdp directory=data_pump_dir logfile=test.log network_link=vxmldb schemas=test dumpfile=test.dmp
