InCache Multicast Clustering Not Working in Sites 220.127.116.11 with WebLogic Patch 28710939 and JDK 1.8.0_172+
(Doc ID 2505227.1)
Last updated on JUNE 04, 2019
Applies to:Oracle WebCenter Sites - Version 18.104.22.168.0 and later
Information in this document applies to any platform.
Multicast Clustering Not Working:
i) The Cluster Info in the Admin UI (e.g. Admin --> System Tools --> Cache Management --> CAS Cache --> Cluster Info) page indicates that "There are no remote cluster members configured for the cache notifier."
ii) inCache (cas-cache, cs-cache, ss-cache, linked-cache) invalidation is not working:
e.g. updating an asset on one node in the cluster is not reflected on the other node.
What is working:
- Support Tool's Multicast testing tool to verify that multicast works; a ping sent from Support Tools arrives, and the other members of the cluster are also visible via the notifier messages.
WebLogic Patch 28710939 was applied and the JDK was updated to greater than JDK 1.8.0_172
