SAP heterogeneous environment DB13 RFC configuration

Hello,

I have installed SAP Central instace on Windows 2008 R2 and install Oracle database 11g on Oracle Database appliance with Oracle Linux operating system. Also installed standalone SAP Gateway in Database host.

SAP Application working fine except DB13 which has auto generated RFC connection.

RFC connection failed with following message.
