Abstract: A method for eligibility list management in a distributed group membership system, including receiving an eligibility list change request with respect to an eligibility list of a group of computing elements, removing from a view of the group any active members in the group who are to be removed from the eligibility list as indicated by the eligibility list change request, preventing any of the members that are removed from the view from rejoining a view until the eligibility list change is applied to the eligibility list, applying the eligibility list change to the eligibility list, and establishing a new view for any active members in the group who are on the changed eligibility list.

Abstract: An apparatus, program product and method utilize distributed coordinating members to distribute member-specific state data to subscribing members in a distributed computing system. Member-specific state data is associated with different subjects, and coordinating members are configured to manage state data associated with particular subjects such that a reporting member that needs to report member-specific state data associated with a particular subject forwards that state data to a coordinating member associated with that subject. Once received, the coordinating member then distributes the member-specific state data to any members that have subscribed to receive state data associated with that subject.
