如何在对等设置中修复gemfire缓存系统中的mcast问题

Question

我在对等设置中使用gemfire缓存。多年来，该系统在gemfire 6上运行良好。我最近升级到gemfire 7并在代理和其中一个进程中得到此错误 -

[main] ERROR  [GemfirePeer] Issues while creating gemfire distributed region : com.gemstone.gemfire.IncompatibleSystemException: Rejected new system node because mcast was disabled which does not match the distributed system it is attempting to join. To fix this make sure the "mcast-port" gemfire property is set the same on all members of the same distributed system. 

mcast-port = 0在所有进程的配置属性中设置。

有人可以提出想法吗？

Answer 1

此消息表示至少有一个已启动的成员将mcast-port设置为非零值，它也可能来自您的6.x安装。 我建议您使用定位器进行成员发现。
