We noticed a problem in our ESB cluster that is not fatal but I was wondering if anyone has any ideas.
We have a FileGateway in our esb. The jboss-esb.xml describes that the esb should look for a file in a specific folder. The problem is that if you have N nodes each with the same version of your esb deployed then all N nodes will attempt to perform the same operation. One of the N servers will succeed while the rest will fail with exceptions similar to the ones I attach to this.
Is there a way to tell the ESB that only the Master node in the cluster should try to look for the file so that this doesn't happen?
The ESB deployments should be no different to any other deployment within the server, so you should be able to use the normal hasingleton mechanism.
