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

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

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> 2.

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.

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.
