      Hi

       

      Can somone enlighten me process of merging?

      I have two cacheManagers running in cluster. I have registered Listener on them.

          
         cacheManager.addListener(new MergedViewListener());

       

           @Listener

           public class MergedViewListener {

               @Merged

               public void mergedView(MergeEvent me) {

                   LOGGER.info("View merged received " + me);

                }

          }

       

      Now when I split cluster and after a while connect it back sometimes this listener is runned and sometimes not and it is followed with this messages

      which I would guess means that merge did not happened.

      What ensures the Merge to be done? JGroups should always ensure that merge should happen?

      When the MergedViewListener is invoked it acctually means that merge was successfull and I can access cacheManager's caches and update them? (To handle update and synchronization after split of cluster occurs)
