Hi, DBC file is manged by Autoconfig, which refer a context file SID_server.xml. Please check context file SID_server.xml file for double slash.
The issue was that the opmn.xml file had a slash at the end of the fnd_secure variable, I removed it and the double slash problem was resolved! I did not edit the script, this was from the install. Possibly not many people have integrated 18.104.22.168 discoverer with EBS and make the call to discoverer from menu in EBS, hence this has not been reported.
