1. A system for hosting a message store on a server, comprising:
- a computer, including a computer-readable storage medium and processor operating thereon;
a lead server that selects a host server from among a plurality of servers that form a cluster in a network using a distributed consensus algorithm, the lead server contacts the plurality of servers to determine whether the host server is acceptable to the plurality of servers, and when the plurality of servers agree that the host server is acceptable, the lead server;
sends a notification to the plurality of servers to commit the host server, andassigns the message store to the host server to provide a sole access point to the message store for the plurality of servers; and
wherein each of the plurality of servers retrieves messages from the host server providing the sole access point to the message store.

Abstract
A system for managing a message store in a network includes an object acting as a message store. In one embodiment, the message store is for Java Message Service. A lead server is selected from several servers. The lead server uses a distributed consensus algorithm to select a host server. The selected host server hosts the message store, providing sole access to the message store. The other servers are notified of the new host by messaging. In one embodiment, servers can send messages to the message store on the host and pick up any messages from the message store.
