  • Publication number: 20060101059
    Abstract: A business system on the Web base having a plurality of system apparatuses and software components aims at reducing a load on configuration works and employment works of the business system. In an employment management system for the business system having a plurality of system apparatuses, a storage device stores unit configuration information, a plurality of methods constituting a common interface, and a program for each method. The common interface has at least a partial halt method for making the unit halt an operation of the business system and a partial restart method for making the unit restart the operation of the business system. When an arithmetic processing part performs employment operations by making a predetermined system apparatus halt the operation of the business system, the unit including the predetermined system is subjected to partial halt, employment operations and then partial restart.
