So tried to figure out the solution of many random issues and accumulating all in here:
1. OCI Launch Error from RAU
When trying to launch java UI from RAU. After providing credentials getting a window where I see client,server, DS, clientJVM, client Plugin, License tab, but not the actual OCI console. Only option I see is ok button. Once I do that, it take me back to login window and throw communication error. Attaching screenshot 0 and 1 for the same.
I tried to use fix of all java issues which were discussed in older versions of java. Is there any update on that document?
2. Since OCI 7.2.3, I am not able to launch DWH/reporting portal from remote systems. I see there is a change in port number from 8080 to 9300. Do I have to put request for additional firewall opening for that specific port, or there is any work around for it? Everytime I have to work on reports, I have to do RDP session to DWH server and work locally.
