– Login to the server with the Oracle BI Applications installed

– Run the following command (in this case it’s a windows server):

D:\instance_name\mwh\Oracle_BI1\biapps\dwrep\Bin\DDLIMP /U siebel /P ***** /a SIEBEL /C tp4u12 /G SSE_ROLE /W Y /B SIEBELDATA /X SIEBELINDEX /F D:\instance_name\mwh\Oracle_BI1\biapps\dwrep\DDL_OLTP.CTL /L D:\instance_name\mwh\Oracle_BI1\biapps\dwrep\DDL_OLTP_instance_name.log

where /C is the ODBC data source name, so take care that you have to create an ODBC system data source first and of course to create it you must have the tnsnames entry first.
