Hi all,
Re:
https://issues.jboss.org/browse/ISPN-7031
A potential solution here would be for the client listener, if it receives a
"Connection reset by peer" IOException, to try to fail over all listeners
connected to that node.
The first tricky aspect is how to make sure that if you have N connected listeners, only
one of them fails over the connected listeners, and hence avoid all connected listeners
trying to failover all of them. A simple solution here would be for each listener to try
to failover itself.
Even more tricky is how to deal with the situation when failover fails. E.g. imagine you
have only one server and connectivity drops. The connect is reset and the failover fails
since there's no other servers. What does the listener do about it? One thing it could
do is failover itself periodically until it works, but this is not ideal. Another option
would be to avoid any failover until the client sends an operation and gets a connection.
The latter option has a bigger chance of missing events but we have the state receiving
option for those who must receive state.
Any other ideas?
Cheers,
