Yeah just tried:
                <invalidation-cache name="realms" mode="SYNC"  start="EAGER"/>
                <invalidation-cache name="users" mode="SYNC" start="EAGER"/>
                <distributed-cache name="sessions" mode="SYNC" owners="2" segments="60"  start="EAGER">
                    <state-transfer enabled="true" />
                </distributed-cache>
                <distributed-cache name="loginFailures" mode="SYNC" owners="2" segments="60"  start="EAGER">
                    <state-transfer enabled="true" />
                </distributed-cache>

Scenario:
 - node1 is up
 - I’m logged in in node 1
 - starting node 2

I get on node1:

Hi,
yeah this helps little bit:
<invalidation-cache name="realms" mode="SYNC"/>
<invalidation-cache name="users" mode="SYNC"/>
<distributed-cache name="sessions" mode="SYNC" owners="2" segments="60" >
<state-transfer enabled="true" />
</distributed-cache>
<distributed-cache name="loginFailures" mode="SYNC" owners="2" segments="60"

<state-transfer enabled="true" />
</distributed-cache>

When both caches on both nodes are up then syncing works fine.
Also /sessions works OK.

But I’m still facing issue no 1.

When node is up I see in logs this:

14:51:19,088 INFO [org.jboss.as] (Controller Boot Thread) JBAS015874: JBoss
EAP 6.4.0.GA (AS 7.5.0.Final-redhat-21) started in 18527ms - Started 242 of
347 services (141 services are lazy, passive or on-demand)

Caches are initialised after first hit not after KC start

Have you tried putting start="EAGER" on both the cache-container and all caches in standalone.xml?


I’m talking about this in log:

It looks it helped.
When I have started both nodes and I see that caches on both nodes are
started then everything is fine.
Scenario: When I login to node1, then stop node1, then I’m redirected to
node2 and I’m still logged in. Great!

But I see two issues right now:
1. Caches are replicated to newly started node too late.
Scenario is:
1. start node1, log in.
2. start node2, wait till you see that node1 knows new node and node2 is
fully started
3. killl node1.

Then I’m redirected to login page.

This happens really only when no request hits newly started node2. If I do
few reloads in browser before I kill node1 then I see in logs that those
infinispan caches are created on node2 and fully replicated.

Is it related to “start = EAGER” ?
Will it help if you use in standalone-ha.xml the config like this? :

<distributed-cache name="sessions" mode="SYNC" owners="2" segments="60" >
<state-transfer enabled="true" />
</distributed-cache>

Same error I get in admin console (
http://localhost/auth/admin/master/console/#/realms/cluster-test/sessions/realm
)
Strange... Are you using "distributed-cache" with mode "SYNC" on both cluster
nodes?

Hi Marek,
your’re right that i’m hitting directly localhsot on different ports.

I was thinking about cookies resp. load balancer so I checked cookies and
they were sent on both ports.

I’ll set up load balancer and I’ll will see.

Hi Libor,

the config files looks good (at least for the first look), but question is if
you're using loadbalancer?

If you're not using loadbalancer and you access keycloak servers directly on
localhost:8080 and localhost:8180, the problem might be just in the fact
that browser cookie KEYCLOAK_IDENTITY is not shared between them and hence
going to localhost:8180 will not find KEYCLOAK_IDENTITY cookie from
localhost:8080 and will try to create new session.

You can check admin console or account management and list available user
sessions on both nodes. If both cluster nodes have same sessions, then
replication of userSessions works fine, but only issue is really the cookie.

I suspect that in production, you will use loadbalancer, so this issue won't
happen.

Subject: [keycloak-user] Clustering on localhost with shared DB

Hi,
I’m trying to achieve full user session replication which means when I’m
logged in on node 1 and then hit node 2 then I expect to be logged in but
I’m forced to log in again.

I have:
1. two localhost nodes with JBoss EAP 6.4 + War installation
2. Postgres
3. EAP cofigured based on
http://docs.jboss.org/keycloak/docs/1.2.0.Beta1/userguide/html/clustering.html

I triedeither
<distributed-cache name="sessions" mode="SYNC" owners=“ 2 " />
<distributed-cache name="loginFailures" mode="SYNC" owners=“ 2 " />
or
<replicated-cache name="sessions" mode="SYNC"/>
<replicated-cache name="loginFailures" mode="SYNC”/>
but with same result.

I’m starting nodes by
./jb1/bin/standalone.sh --server-config=standalone-ha.xml
-Djboss.node.name=node1
./jb2/bin/standalone.sh --server-config=standalone-ha.xml
-Djboss.socket.binding.port-offset=100 -Djboss.node.name=node2


both jb1 and jb2 are identical and they know each other (Received new cluster
view: [node1/keycloak|1] [node1/keycloak, node2/keycloak])

How do you test clustering of KC please?
