Processing a unit of work

A client computer batch message transaction group is created that includes a set of client computers from which messages are committed as a batch messaging transaction to a single message reception queue. In response to receiving separate messages from at least two of the set of client computers within the client computer batch message transaction group, the separate messages are grouped under the batch messaging transaction as a single unit of work to commit to the single message reception queue. A single batch transaction commit decision is computed based upon whether a write of each of the separate messages grouped within the single unit of work to the single message reception queue is successful.
