You might face an issue with 12.1.3 OSB web based test console not working when you press the “Play” button from OSB console. You might see following error:
Error Accessing Test Configuration
"Test Console" service is not running. Contact administrator to start this service.
Manual instructs you to set the Admin Server listen address to something else than empty (which means admin server listens for all IP addresses). An example of “localhost” could be valid if you are running your installation e.g. on your own workstation.
In my case I had to also set the listen addres for the osb server as well in order to get the test console working properly. After setting the listen address you need to bounce the servers.
