Clustering Identity Manager

Question

I am interesting in knowing more about Clustering IDM. We have IDM running on Tomcat with Oracle DB
Please let me know what your thoughts are on this and whats the best way to do this. Feel free to tell me where I can find more reference material on this.
Thanks

Answer 1

Yes, you install glassfish on an admin node and on several app nodes, deploy the app via the admin node and it automatically deploys to the app nodes. The app nodes have a load balancer in front of them. If one app node goes down, the load balancer stops sending web traffic to it.
Within each individual resource configuration, you can also tell the resource adapter which app node to perform reconciliation on. For example:
========= LB =========
    |        |
app-a app-b app-c app-d admin
    |        |        |        |         |
--------------------------------------------------------admin network (ldap, AD, DB, traffic)app-a and app-b are "web nodes" that handle use traffic 50/50 (password changes, admin web interface, etc)
app-c and app-d are "processing nodes" that handle activesync and reconciliation
If a node dies, everything fails over and keep running. If you need more nodes, just create a new node on another server and add in into the mix.
Glassfish handles the clustering, the load balancer handles the user-visible HA, and IDM handles distributing the processing workload to the app nodes.
OK, I hope my ASCII art above looks OK....
