Examples of org.infinispan.commands.control.CacheViewControlCommand

org.infinispan.commands.control.CacheViewControlCommand
A control command to coordinate the installation of cache views between the members of the cluster. The coordinator will receive REQUEST_JOIN and REQUEST_LEAVE commands from the nodes starting or stopping a cache. It then sends PREPARE_VIEW to all the nodes in the cluster. If all nodes return a successful response, the coordinator then sends a COMMIT_VIEW command to everyone. If there is a failure on one of the nodes, the coordinator cancels the view with a ROLLBACK_VIEW command. @author Dan Berindei @since 5.1

      log.tracef("%s: Rolling back to cache view %d on %s, new view id is %d", cacheName, committedViewId, validTargets, newViewId);


      try {
         // it's ok to send the rollback to nodes that don't have the cache yet, they will just ignore it
         // on the other hand we *have* to send the rollback to any nodes that got the prepare
         final CacheViewControlCommand cmd = new CacheViewControlCommand(cacheName,
               CacheViewControlCommand.Type.ROLLBACK_VIEW, self, newViewId, null, committedViewId, null);
