Abstract：Aiming at the randomicity and unpredictability of the change of node-state in distributed and parallel database system DPSQL,the dynamic scheme was put forward to handle the management and maintenance of the node information.The scheme was implemented on the basis of the correctness and consistency of the information table where every active node-state was written and refreshed on time.This ensured the correspondence of all server nodes and the cooperation of inner subsystem in each node.Consequently,it ensured the effective service of DPSQL.
