Abstract: A router receives a transaction message. The router determines whether the transaction message may include an affinity indicating a preference regarding processing of the transaction message. The transaction message may be modified to include an identification of a server system to process the modified transaction message based on the determination of the affinity. The router may route the modified transaction message to a coupling facility. A notification message may be received from the coupling facility, where the notification message requests a server associated with or including the router to send a bid to process the modified transaction message. The router may send the bid to process the modified transaction message to the coupling facility. An authorization message, to process the modified transaction message, may be received from the coupling facility based on a timestamp of the bid.

Abstract: A transaction message is received at a router. A determination is made whether the transaction message includes an affinity. The affinity indicates an administrator-specified preference regarding processing of the transaction message. When the transaction message includes the affinity, a server system to process the transaction message is identified based on the affinity and based on a system affinity of the server system. The system affinity specifies processing characteristics of the server system. The server system includes a set of servers. The transaction message is modified to identify the server system and routed to a message queue.
