Management apparatus and method for managing a startup of an operating system

A management apparatus for managing a startup of an operating system, comprising:

• a management table containing description of an execution order of modules constituting an operating system, expected execution time for each module, and real execution time for each module;
• a control unit to control an order of executing the modules based on the execution order described in the management table;
• a measurement unit to measure the execution time of each running module;
• a judgment unit to judge that the execution of the module is completed successfully and to write the real execution time in the management table when the real execution time at the end of execution is equal to or shorter than the expected execution time, the judgment unit to judge that a failure occurs during the execution of the module and to write a flag for defective condition in the management table when the execution is not completed even after the real execution time exceeds the expected execution time;
• and
• an acquisition unit to acquire and store system information at every time point when the judgment unit makes a judgment, wherein
• when the flag for defective condition is written for the module in the management table, the control unit stops the execution of the running module and starts the execution of a next module.

A method for managing a startup of an operating system, comprising:

• starting an execution of a module based on an execution order of modules composing of an operating system and expected execution time for each module, the execution order of modules describing in a management table containing description of a real execution time for each module;
• starting a measurement of an execution of each running module;
• judging that the execution of the module is completed successfully and writing the real execution time in the management table when the real execution time at the end of execution is equal to or shorter than the expected execution time, judging that a failure occurs during the execution of the module and writing a flag for defective condition in the management table when the execution is not completed even after the real execution time exceeds the expected execution time;
• and
• stopping the execution of the running module and starting the execution of a next module when the flag for defective condition is written for the module in the management table.
