Maksim,
There is this config setting
cas.ticket.registry.hazelcast.cluster.members=
Add IPs of all members to the list.
https://apereo.github.io/cas/6.1.x/configuration/Configuration-Properties.html#hazelcast-ticket-registry
and the link to common settings.
There are some hazelcast loggers in log4j2.xml
<AsyncLogger name="com.hazelcast" level="${sys:hazelcast.log.level}"
includeLocation="true" />

Ray,
I asked about CAS functionality to distribute tickets across nodes. I need
specific CAS functionality based on Hazelcast and seems to me this
functionality doesn't work as expected so I need to check it somehow. Maybe
with some debug logging.
I have a cluster with several nodes of CAS with hazelcast ticket registry and I
have a load balancer. If I turn off sticky sessions CAS asks me about
username/password every time. This cluster works in the same way without
hazelcast ticket registry. So seems to me this functionality doesn't work and I
don't see any errors in the logs.

Maksim,
I do not know if there is a stand alone client for accessing hazelcast data. In
the docs, https://docs.hazelcast.org/docs/4.0/manual/html-single/index.html,
there is a section on clients and one on management. It looks like you would
have to create an application yourself but someone has probably done that
already.

Hi Ray,
Seems to me Hazelcast doesn't distribute data across all nodes because each
node doesn't have information about sessions on other nodes.
How to check data distribution?

Maksim,
Hazelcast is distributed but not replicated. Thus, when a server goes down, the
tickets on that server are lost. You have to relogin only if your ticket was on
that server.
Hazelcast has some mechanism of determining which node has which ticket. It may
also be possible to make hazelcast replicated but I have not tried.
Ray
P.S. you have two node3s in your config.

Hi Andy,
Your example is very helpful. Thank you.
I see how hazelcast tickets registry works on my local env. I turned off active
container and another container continues to work with my active session
without relogin.
However on my remote env. with CAS 6.1.3 it doesn't work in this way. Load
balancer ask me to re-login If I turn off active container.
Each node with hazelcast sees other nodes. I see such messages on all nodes in
case node1 is turned off:

This is my hazelcast settings:
cas.ticket.registry.hazelcast.cluster.members=node1:5701,node2:5701,node3:5701,node3:5701
cas.ticket.registry.hazelcast.cluster.asyncBackupCount=3
cas.ticket.registry.hazelcast.cluster.port=5701
cas.ticket.registry.hazelcast.cluster.portAutoIncrement=false
cas.ticket.registry.hazelcast.cluster.instanceName=localhost
cas.ticket.registry.hazelcast.cluster.publicAddress=node1:5701
cas.ticket.registry.hazelcast.cluster.tcpipEnabled=true
Why hazelcast doesn't share data across the cluster?
These messages I see on startup

Hi Maksim,
Pretty sure:
cas.ticket.registry.hazelcast.cluster.public-address
and
cas.ticket.registry.hazelcast.cluster.publicAddress
Both works the same, since spring property allows both camelCase and kebak-case.
And I did successfully use docker CAS and use Hazelcast as ticketing system,
however I am using it for demo so I just included a whole bunch of private IP
so it works......
here's my CAS properties:
cas.ticket.registry.hazelcast.cluster.members=172.20.0.1,172.20.0.2,172.20.0.3,172.20.0.4,172.20.0.5,172.20.0.6,172.20.0.7,172.20.0.8,172.20.0.9,172.20.0.10
cas.ticket.registry.hazelcast.cluster.instanceName=localhost
my project link as well so you can reference if want to:
