So I thought to make a post on this issue. Issue Faced After I entered creds to login to my R12.2, faced the below screen. On checking the log found the below issue. From the issue, I understood something is not correct with the port 12345. So I checked metalink and found two documents talks about the same issue. So I followed the test cases described there and the results from my environment are same as the results of oracle document.  In my case the instance where I'm facing the issue is not a recently cloned one.
