Cluster RTC internal (2.0.0.2)
On the documentation about H.A on RTC internal of RAM, this document (http://www-01.ibm.com/support/docview.wss?uid=swg21445763) explain how to configure it. I would like to try another possibility:
A common WAS cluster where a node is the master and active and another that is turned off, but make part of cluster, in case of disaster, the WAS Admin would turning on the inactive node of the cluster without change any configuration of RAM.
What problems and implications are there?

The net net is that in this environment you will have to have RTC installed on every instance of the cluster, and ONLY one could be active at the time.
What is the reason for having a single clusters, vs. two clusters? RTC does not recommend to run on a cluster.
Well, the only reason to put the RTC in a cluster, is a maintenance facility, instead of change webservers' plugins, load balance configs, etc., the operation area just launch the inactive node, taking care to prevent that the old "master" node doesn't go back together with the current one.
Hi all,
Until internal RAM/RTC really support clusters, it's impossible installing one in. At the moment to select the server to deploy each app, on the ram.setup, if there isn't a single server created, the list of servers to install a RTC appears empty.
I'm not able to install a RTC in a cluster, even I'd only one instance active.
