( Pega V 7.1.8) java.lang.ClassNotFoundException: Failed to load class com.pega.pegarules.session.internal.authorization.ContextMapDiagCallback
Hi,
I am having 2 Clusters, each cluster has 2 managed servers. I am using proxy servlet in a different managed server which is not there in these 2 clusters to perform load balancing.
Whenever the request switches from one system to another, we need to replicate the sessions, for that I have configured the weblogic.xml i.e
<session-descriptor>
<persistent-store-type>replicated</persistent-store-type>
</session-descriptor>
When I deployed the application into clusters, the managed servers in cluster 2 throw this error
<Aug 27, 2015 2:29:28 AM IST> <Error> <Cluster> <L-MAA-25004251> <ms4> <[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1440622768965> <BEA-000126> <All session objects should be serializable to replicate. Check the objects in the session. Failed to replicate a non-serializable object.

this happens when a serializable object references a non-serializable object.
Anything I am doing wrong? could anyone help me with this.

This is seen when app server specific session replication is turned on (I have seen this on tomcat server too). I do not think Pega is using any of these, nor do we recommend that. Here is a pdn article, while a little out of date, but the essence remains valid: https://pdn.pega.com/performance/recommendations-for-load-balancing-and-weblogic-session-replication-42
