Please do not use 1 job for multiple systems. If one system is down, all is down. Have one job read the existing data queue and send to a new data queue for each system. Now forget your socket program. Have a remote data queue on each system that point to the local data queue on the source system. Now just read the remote data queue on each destination system as if it was a local data queue. To help organize your systems and queues, create a library for each system and a data queue for each application. No communication programming necessary cause IBM has done it for us.

Currently the application uses a single persistent socket connection. However, the application needs to be changed so that sends messages to four different hosts for redundancy. I am not sure the best way to switch between sockets. The easiest way to change the application would be to just switch between sockets but each time I send a message it would have to wait to receive a reply before processing a new message. That doesn't seem to be very efficient. I would like to be able to send/receive messages on all four socket connections at the same time but I don't know how to do this. I have very little socket programming experience so any help would be appreciated.
