Coherence Cache Out of Sync After Deploying EAR Application to Cluster (Doc ID 2663171.1)

Last updated on SEPTEMBER 18, 2023

Symptoms

The EAR Application is deployed in WebLogic server use distributed cache on 2 servers in Coherence cluster. Even though the distributed-scheme is configured, WebLogic is creating separate cache for each server individually. Because of this, requests processed by Server 1 are cached and Server 2 doesn't have any of that cache from Server 1. So when a same request is initiated again from Server 2 it treats this request as new and execute process again, causing servers cache out of Sync. coherence-config-cache.xml is configured to same file path on both servers and coherence cluster created for multicast on both servers.
