[keycloak-dev] Keycloak Clustering 1.1.0.Final - Getting infinispan type casting error (DefaultCacheContainer to EmbeddedCacheManager) in DefaultInfinispanConnectionProviderFactory

[Bappaditya Gorai (bgorai)]

Hi ,
Thanks for your response.

keycloak-war-dist 1.1.0.Final works for me too.

Actually I have custom application similar to "ups-auth-server" . In pom.xml I am using  "keycloak-dependencies-server-min" artifact  and added necessary infinispan related dependencies (keycloak-connections-infinispan, keycloak-model-sessions-infinispan, keycloak-invalidation-cache-infinispan).


Yes, I have added additional "infinispan-core" dependency in my pom.xml as jboss class loader was unable to find EmbeddedCacheManager.class .


I see in your pom.xml you are using "keycloak-dependencies-server-all" , do I need to use the same ( although I may not need all the dependencies)?

Thanks

Hi,

I can't reproduce the issue. It's strange as org.jboss.as.clustering.infinispan.DefaultCacheContainer is subclass of org.infinispan.manager.EmbeddedCacheManager. Didn't you do some packaging changes like adding infinispan jars to auth-server.war/WEB-INF/lib or something like that?

What I did for clustered Keycloak on EAP 6.3:

1) Unpack keycloak-war-dist 1.1.0.Final to my jboss-eap 6.3
2) Configured standalone/configuration/standalone-ha.xml and add this under infinispan subsystem:

 <cache-container name="keycloak" jndi-name="infinispan/Keycloak" start="EAGER">
  <transport lock-timeout="60000"/>
  <distributed-cache name="sessions" mode="SYNC" owners="2" segments="60"/>
  <distributed-cache name="loginFailures" mode="SYNC" owners="2" segments="60"/>
  <invalidation-cache name="realms" mode="SYNC"/>
  <invalidation-cache name="users"  mode="SYNC"/>
 </cache-container>

3) Configured standalone/configuration/keycloak-server.json and add this:

"connectionsInfinispan": {
    "default" : {
        "cacheContainer" : "java:jboss/infinispan/Keycloak"
    }
}

and also switch realmCache, userCache and userSessions to use: "provider": "infinispan"

4) Then run server with command:
./standalone.sh -c standalone-ha.xml

Let me know if these steps work for you.

In my standalone configuration file I am using following subsystem version for infinispan, not sure whether it has any relevance to my issue.

<subsystem xmlns="urn:jboss:domain:infinispan:1.5">

Hi Team,

I am trying  configure  Keycloak in clustered environment (EAP 6.3), however getting following error (stack trace is provided below) . I have followed instructions provided in "Chapter 24. Clustering" in Keycloak Guide (http://docs.jboss.org/keycloak/docs/1.1.0.Final/userguide/html/clustering.html). Let me know if I am missing something.
