Information processing apparatus, information processing system, information processing method and program storage medium

An information processing apparatus which communicates via a network with a server, the information processing apparatus comprising:

• a first processing unit;
• and
• a second processing section which functions as part of a second processing unit included in the server and executing a processing instead of the first processing unit, wherein
• the first processing unit switches a processing unit which executes an application to either of the first or the second processing unit, and
• the second processing section has a function which communicates information with the server via the network, in case of switching from the first processing unit to the second processing unit and displays a result of the processing executed on the second processing unit in the server,
• wherein the first processing unit executes a processing other than the application in case that the first processing unit switches the processing unit from the first processing unit to the second processing unit,
• wherein switching from the first processing unit to the second processing unit is performed in case that abnormality occurs to an operating system or a middleware executed by the first processing unit, and
• wherein the first processing unit executes a recovery processing from the abnormality as a processing other than the application.

An information processing apparatus which communicates via a network with a client terminal, the information processing apparatus comprising:

• a second processing unit which executes a processing instead of the first processing unit included in the client terminal, wherein
• the second processing unit switches a processing unit which executes an application to either of the first or the second processing unit based on a direction from the client terminal, and
• the second processing unit transmits a result of a processing to the second processing unit of the client terminal in case of switching from the first processing unit to the second processing unit,
• wherein switching from the first processing unit to the second processing unit is performed in case of updating an operating system or a middleware executed by the first processing unit.
