Got this error on one Middleware management console when it could not access my webtier
configuration settings are unavailable because
The Webtier was up but it was not recognized as up found this metalink doc ID 1424924.1 and made these changes and it worked from then on out.
Set the Middleware Management Console Listen port mine by default was empty even though I do not have multiple addresses on the server.
I also had to restart the server, I am guessing this is because I have multiple Middleware Management Servers on a single node.
