OWB Transfer- Exporting Metadata (using Bridge)

[boligoma]

Hi,
I want to export metadata, in order to use Oracle BI Beans.
Does anyone knows what should I do?
I tried with the OWB transfer (bridge) but I get an error, it seems the OWB Transfer is doing nothing.
What user and host I need to use in the transfer parameters?
Do I need another user with sysdba privileges (I'm not the DBA)?
What does the bridge does? It creates another rdbms, instance, schema?

Any help would be appreciated.
Thanks in advance.
