Why seeing cache data loss in the FMW domain during app and data modules redeployment? (Doc ID 2676857.1)

Last updated on MARCH 23, 2022

Applies to:

Oracle Coherence - Version 12.2.1.0.0 and later
Oracle WebLogic Server - Version 12.2.1.0.0 and later
Information in this document applies to any platform.

Symptoms

The customer has observed that in the flow of "undeploy" and "deploy" modules they open a jvisualvm/jconsole to the JMX node to check the data of the caches and cache services. Then they perform a suspendService of services. Then they perform undeploy of APP modules and DATA module. When undeploy of the modules has finished, if they consult in jvisualvm/jconsole to verify whether the services are not active, they still see that in the services tab, it still maintains the services. The procedure they follow for the redeployment is :Suspend storage enabled services->Undeploy->Resume storage enabled services -> Deploy modules: however, intermittently they see data loss.
