Table 5-63 Valid Values for metadata-source.send-refresh-command

Value Description


(Default) To propogate refresh commands to the cluster, you must configure RCM and use the eclipselink.deploy-on-startup property.




If cache coordination is configured and the session is deployed on startup, this property controls the sending of RCM refresh metadata commands to the cluster.

These commands will cause the remote instances to refresh their metadata.
