Abstract: In the present invention, a management system has a storage device and a processor. The storage device holds an information processing program for controlling information pertaining to a storage system by utilizing a database. The processor executes an update program that updates the information processing program and the database utilized by the information processing program. The update program calculates an estimated update time needed to update the information processing program and the database on the basis of the size of at least a portion of the database utilized by the information processing program before being updated and the structure of the database utilized by the information processing program after being updated, and outputs the estimated update time thus calculated.

Abstract: A hierarchical communication network management system is structured by a plurality of agents and sub-managers connected to lower communication networks and an integration manager connected to a higher communication network. Each of the sub-managers functions as an agent to the integration manager and functions as a manager to each agent, so that it becomes possible to employ a Simple Network Management Protocol (SNMP) between each agent and its sub-manager and between a sub-manager and the integration manager.
