Refreshing objects in weblogic cluster

[TechResearcher]

Hi

I have a requirement which goes like this:

Environment: Weblogic, Oracle

There is a master table whose mapping pojo is loaded and cached into
the multiple clusters(managed servers) of weblogic. Now I need to
update this cache whenever there are any changes to this master
table(THIS TABLE GETTING UPDATED VERY RARELY).

Any ideas how to do this?

Thanks
