ABSTRACT:
Actions responsive to changes in the state of independent process groups whose process members are spread across a group of nodes in a distributed computing environment. The process groups are arranged in a hierarchy having source process groups and target process groups immediately above and dependent upon the source process groups. A change in the state or membership of a process group will result in a group services function of the nodes in the group injecting the change into the source group members of the affected group. When the action is successfully completed, the change is reflected up the hierarchy to the target group member or members. Upon successful action by the target group, the target group becomes the new source group which in turn may have target groups, and the changes are again reflected up the hierarchy to the new target groups.
