In your local environment, when re-deploying a portlet that uses Service Builder generated code, you might have the error “Cache is not alive” on your custom entities.
To solve it, just add the following properties in your
portal-ext.properties file. It will disable hibernate caching (do this on your local environment only).
hibernate.cache.use_query_cache=false hibernate.cache.use_second_level_cache=false hibernate.connection.isolation=4096
