We have the requirement of implementing LoadBalancer for Areplicate servers. We have 2 Areplicate servers out of which only one is active at a time, and we make the entry of that in AEM. If the Active server is down and we bring the other one up, we have to manually add the secondary server on AEM. Now, we have a Load Balancer on top of the Attunity servers, which redirects to the Active Areplicate server. If there is a possibility that we can add the LoadBalancer IP in AEM add server wizard, it would help us to avoid adding the server manually in case when the Active server goes down.
What happens today if you try to add the LoadBalancer IP to Enterprise Manager? Or are you asking for Enterprise Manager to implement a listener that will always point to the active Replicate node?
Options today would be to just monitor both Replicate servers in Enterprise Manager knowing that only one would be active at a time. Also, you could consider using Enterprise Manager API to automate this process when failover between servers does happen.
