Has anyone used Netscaler as a load balancing configuration for a clustered PAM setup?
Do we absolutely need a loadbalancer?
Can a domain orchestrator distribute workload against other orchestrator by itself?
Yes, a load balancer is currently required to setup a clustered Orchestrator.
Currently we have tested and provide basic configuration examples for Apache, NGINX and F5.
I believe Netscaler has been setup and used to load balance Orchestrators, but do not have any details on the required configuration.
Okay. Thank you.
And can we configure a Master domain orchestrator with slave domain orchestrator without a load balancing solution?
Master DC will distribute workload against its slaves?
All cluster configurations require a load balancer.
And what is the usage of the slave and master domain orchestrator?
These terms no longer really apply to orchestrator clusters. In the past, the first orchestrator you installed was the master and was the only node that could do certain actions.
After 4.2 Sp2, 'Master' simply refers to the first of your cluster nodes that is started. Whatever nodes in a cluster is started first will assume the 'master' role.
Thank you Micheal.
Our cluster ENV is now working with NetScaler.
I have a question though.
When you assign a pending action in Catalog with PAM, the process stays in a waiting state.
When the pending action is terminated, catalog sends a message to PAM to continue.
What will happen if the load balancer sends this message to the orchestrator who is not waiting for it?
We do have a requirement for sticky or persistent sessions to be enabled at your load balancer, but If I understand the update from Catalog correctly it is a generic update for 'ROID = 12345' or similar and should work regardless of the node which receives the update.
Yes we configured the persistent sessions on the NetScaler. But if a pending action take two weeks to complete, the netscaler does not hold sessions for this long
I'll keep you updated.
Can you share what you had to do on Netscaler to make it work with PAM nodes? Did you convert the irules files to work with NetScaler?
I do not know what an irules file is but we did not do nothing fancy to get it work.
I've asked NetScaler team for a "entry" in netscaler balancing between 3 PAM nodes. Sticky session, healtcheck.
We associated the netscaler's entry IP with a dns name pam.domain.local.
Used this DNS in PAM setup for the load balancer name.
Used Node1, Node2, Node3 for the node name. Nodes were installed by using the install orchestrator option in the GUI.
Everything is working fine since November 2016.
