Abstract: In an exchange system, conditions under which the exchange accommodates a package or module is registered in a storage unit in the exchange. Growth scenario data indicting a package type and the processes necessary for installing the packing in the exchange (package growth) is recorded in each package. When a package is newly installed in the exchange, it is determined whether the package satisfies the accommodation conditions by identifying the position at which the package is installed and the package type. If the package satisfies the accommodation conditions, a growth procedure scenario is created on the basis of the growth scenario data recorded in the package and registered in the storage portion. A package growth process is then executed in accordance with the growth procedure scenario.

Abstract: Accommodation conditions data under which an exchange accommodates a package is registered in the storage unit in a system, and a growth scenario data indicating a package type and the process for necessary for package growth is recorded in each package. When a package is newly installed in the exchange, whether or not the package satisfies the accommodation conditions is judged by identifying the position at which the package is installed and the package type. If said package satisfies the accommodation conditions, a detailed growth procedure scenario is created on the basis of the package growth scenario data recorded in the package and registers it in the storage portion, and a package growth process is interactively executed in accordance with the detailed growth procedure scenario.
