This invention relates to a method for extending nodes in a network in which all network nodes maintain a membership list. The method steps include (a) sending an invitation to join by a first node to a second node; (b) recording the message and either rejecting the invitation if the first node identity is not listed at the second node or accepting otherwise; and (c) if rejected, sending an invitation to the first node which accepts. In a distributed database environment, consisting of multiple database sites interacting over a communication network, it is important to be able to add a new database site to the distributed database network without requiring simultaneous system generation activity at all the sites of the distributed database system.
