Question

How can I rediscover members of a group by its cluster-name? I am using JGroups 2.7.0 In a particular situation, members are isolated and are not connected (network failure) and when the network is back up, I would like to know all other members so they are in the same group again.

Thanks in advance.

Was it helpful?

Solution

When the connection to the network is established, trigger FIND_INITIAL_MEMBERS event up in the stack using MERGE2 protocol of the stack and that will merge all the isolated members together.
