I am running Toad Data Modeler version 188.8.131.52 and Oracle 10g instant Client ( Not SQL NET Client ) on a Windows XP laptop. TDM is giving me the following error when trying to access reverse Engineering->universal reverse :
'Cannot locate file oci.dll'
User has to install a SQL Net client or for the native connection, select "Connection via TCP/IP" and fill out appropriate text boxes.
Select 'Connection via TCP/IP' in the ODAC Connection setup dialog and fill out the Host and Port fields (1521 by default). Be careful about Service Name and Net Service Name. - They are different. For the "Connection via TCP/IP", user have to fill out the Service Name.
