You can experience problems opening the WebLogic Server Administration Console from Fusion Middleware Control.
You can use the WebLogic Server Administration Console and Fusion Middleware Control to administer Oracle Java Cloud Service instances. If you attempt to open the WebLogic Server Administration Console from the Fusion Middleware Control Console, the console will not open and you will receive an error message:
The Host is not resolvable. Most commonly this is due to mistyping the URL in the browser bar. Please verify the spelling and that the site exists and hit refresh.
The problem occurs three ways.
From the Deployments tile:
Click on the Deployments tile.
Click the name of your deployed application.
From the Domain Application Deployment drop-down menu, select Administration — General Settings.
Select the Instrumentation tab.
In “To configure Instrumentation, use the WebLogic Server Administration Console,” click Weblogic Server Administration Console.
The error message appears in a new browser tab.
From the WebLogic Domain drop-down menu:
From the WebLogic Domain drop-down menu, select WebLogic Server Administration Console.
The error message does not appear, but neither does the WebLogic Service Administration Console.
When administering a security realm from the WebLogic Domain drop-down menu:
From the WebLogic Domain drop-down menu, select Security — Security Realms.
Select Settings for Security Realm.
Click WebLogic Server Administration Console.
The error messaged appears in a new browser tab.

In the Oracle Java Cloud Service environment, only HTTPS port 7002 is enabled and accessible because it is a secure port. Additionally, the Administration Server VM host is not DNS resolvable to its IP address because the IP address is a public NAT IP address.
Use the HTTPS protocol, NAT IP address instead of host name, and port 7002 to access the console, for example:
