RDM setup in High-Availability Environment
Does anybody have experience with setting up RDM 4.0.1 in a high-availability environment?
This setup includes:
-
CLM 4.0.1 (Rational Team Concert 4.0.1, Rational Quality Manager 4.0.1, Rational Requirements Composer 4.0.1)
- WebSphere Application Server Network Deployment (WAS ND) and Microsoft SQL Server 2008
Accepted answer
RDM does not support being in a clustered deployment, but it tolerates being registered to a JTS being in a clustered deployment. CLM can be set up according to the instructions here:
https://jazz.net/wiki/bin/view/Main/DeployingCLMClusterWithWASND
RDM can then be deployed on a separate server and be registered against the shared JTS.
Alternatively, RDM can be added to a manual failover configuration (in cold standby only). Instructions on how to deploy that type of configuration can be found here:

Hi Thomas,
I just want to clarify what you mean by:
"RDM can then be deployed on a separate server and be registered against the shared JTS"
Does this mean that RDM will need to be deployed on a separate server to the rest of CLM? Currently we have RDM installed together with the rest of CLM on one server, so would it mean having to perform a server rename (or use a reverse proxy) for RDM if it is moved to a separate server?
Alternatively, can we install RDM in a new WAS ND profile on the same server?

Hi Sudheer,
RDM can be deployed on the same server as CLM as long as the server is not part of a cluster.
If CLM is clustered, then it would still be possible to deploy RDM on a node outside the cluster so you wouldn't have to change the public URI.
