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:

  1. CLM 4.0.1 (Rational Team Concert 4.0.1, Rational Quality Manager 4.0.1, Rational Requirements Composer 4.0.1)
  2. WebSphere Application Server Network Deployment (WAS ND) and Microsoft SQL Server 2008

Hi Jaco,

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.
