Information processing apparatus and information processing system

An information processing system, comprising:

• a first information processing apparatus;
• and
• a second information processing apparatus configured to take over processing of the first information processing apparatus upon transitioning to an activation state;
• wherein
• the first information processing apparatus includes:
• a memory configured to store first information and second information, the first information including a permission time with respect to each of a plurality of operation states of the first information processing apparatus in the activation state, the permission time being a time allowed for switching the second information processing apparatus from a standby state to the activation state, the second information being provided in the second information processing apparatus and including an activation time required for activating each of a plurality of modules which operate when the second information processing apparatus is in the activation state;
• and
• a first processor coupled to the memory and the first processor configured to:
• determine a current operation state of the first information processing apparatus in the activation state;
• identify one permission time corresponding to the current operation state from among the first information;
• determine stop modules among the plurality of modules such that a total time for activating the stop modules is equal to or less than the one permission time based on the second information, the stop modules being modules to be stopped;
• and
• transmit a stop instruction to the second information processing apparatus in the standby state, the stop instruction instructing to stop the stop modules, and
• the second information processing apparatus includes a second processor configured to:
• control to stop the stop modules in accordance with the stop instruction;
• and
• activate the stop modules when the switching is started.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a process, the process comprising:

• determining a current operation state of the computer in the activation state;
• identify one permission time corresponding to the current operation state from among first information including a permission time with respect to each of a plurality of operation states of the computer in an activation state, the permission time being a time allowed for switching a substitute computer from a standby state to the activation state, the substitute computer taking over processing of the computer upon transitioning to the activation state;
• determine stop modules, among a plurality of modules which operate when the substitute computer is in the activation state, such that a total time for activating the stop modules is equal to or less than the one permission time based on second information provided in the substitute computer, the stop modules being modules to be stopped, the second information including an activation time required for activating each of a plurality of modules which operate when the substitute computer is in the activation state;
• and
• instruct the substitute computer in the standby state to stop the stop modules.
