<p>A program to be updated is identified among plural programs stored in a storage device in response to a program update instruction, and a replacement process that is a process corresponding to the identified program to be updated and is included in plural processes activated by executing the plural programs and a communication destination process that has communicated with the replacement process and is included in the plural processes are extracted. Then, in response to updating with update data including a new program of the identified program to be updated, the new program is loaded onto a work memory to activate a first process to be substituted for the replacement process, and a second process to be substituted for the extracted communication destination process is activated. Furthermore, communication connection relationships associated with the replacement process and the communication destination process is disconnected, and communication connection relationship associated with the first process and the second process is built, and the replacement process and the communication destination process are terminated. Thus, program update can be reflected without rebooting.</p> |
