Coherence includes network-level fault tolerance features and transparent soft re-start capability to enable servers to self-heal. When a new server is added, or when a failed server is restarted, it automatically joins the cluster and Coherence fails back services to it, transparently redistributing the cluster load. Coherence has no single points of failure it automatically and transparently fails over and redistributes its clustered data management services when a server becomes inoperative or is disconnected from the network. The WebLogic Server infrastructure supports the deployment of many types of distributed applications and is an ideal foundation for building applications based on service-oriented architecture (SOA).Ĭoherence provides replicated and distributed (partitioned) data management and caching services on top of a reliable, highly scalable peer-to-peer clustering protocol. (The key being that we already had the ESX cluster and load balancer).Table A-1 Oracle Fusion Middleware WebLogic Server and Coherence Products and Feature Sets Installation TypeĪ scalable, enterprise-ready Java Platform, Enterprise Edition (Java EE) application server. It’s not true clustering, but it provides a level of availability that we are comfortable with, and it diidn’t cost us an arm and a leg to implement. The load balancer redirects clients to the alternate server within about five seconds of the service becoming available.
If the active server should go kaput, or I want to switch servers to perform mantenance, I shut down the Openfire service on the active server, and bring it up on the stand-by. The load balancer routes client traffic to which ever server is listening on port 5222. The two servers are front-ended by an F5 load balancer. At any given time, one is active and the other is passive. They are both configured for the same IM domain and point to the same DB, but they are not clustered as far as Openfire is concerned. The servers are configured as identically as possible. I have anti-affinity rules set up in VMWare so that the two VMs never run on the same physical host. Each on is configured with 4 GB RAM and two vCPUs. They are VMs on a VMWare ESX HA\DRS cluster. Fault Tolerance for the DB is managed by a separate team, so that’s not a consideration for my design.

We opted not to go for the coherence license and go for “poor man’s clustering”. I’m in the middle of an implementation for 4000 users.
