[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: JBMESSAGING-674 - Propagating changes on ClusteredConnec

[clebert.suconic@jboss.com]

I'm thinking about how to fix this racing condition:


I - ClientClusteredConnectionFactoryDelegate has this following failoverMap:

Server 1->Server2->Server3->Server 1

II - Server1 is killed

III - Now the CF::failoverMap is updated to:
Server2->Server3->Server2

IV - A failure happens on a connection directed on Server1. FailoverMap doesn't have the information about Server1 any more.


I will keep coding and maybe we will need to have the failoverMap on the Connection instead of ConnectionFactory, and having failover updating these fields on Connection only when a failure happens.

As I said I am thinking about how to fix this, and I'm almost sure how to fix this. I wanted to post this just to keep the team informed.
