Abstract:
1. For a clustered database management system (DBMS) operatively coupled to a data processing system having memory for storing a database, a method for asynchronous interconnection between a first and a second node of the clustered database management system, the first and the second node each having a processor and a memory, the method comprising the steps of: a) associating a first node timestamp with the first node when the first node is started and a second node timestamp with the second node when the second node is started; b) establishing a connection between the first node and second node by two or more communication conduits, wherein the two or more communication conduits each have an associated session identifier; c) associating the session identifiers with the first node timestamp and the second node timestamp; d) receiving, at the first node, another timestamp from the second node; e) comparing the received another timestamp from the second node to the second node timestamp associated with the session identifiers; and f) initiating, in response to the comparing, communications between the first and second nodes via the communication conduits.
