Abstract

It is provided a non-transitory computer-readable recording medium storing a program that causes an information processing apparatus which includes a plurality of memory areas and executes a first process and a process for rebooting the information processing apparatus and a second process. The information processing apparatus executes initializing a memory area of the plurality of memory areas as a memory area used for executing the first process, storing first information in a memory area, the first information indicating whether each memory area of the plurality of memory areas is initialized, executing the first process by using the memory area initialized as the memory area used for executing the first process, and initializing according to the first information, during the process for rebooting the information processing apparatus, a memory area which is not initialized as a memory area used for executing the second process.

Claims

1. A non-transitory computer-readable recording medium storing a program that causes an information processing apparatus which includes a plurality of memory areas and executes a first process and a process for rebooting the information processing apparatus and a second process to execute:

initializing a memory area of the plurality of memory areas as a memory area used for executing the first process;

storing first information in a memory area, the first information indicating whether each memory area of the plurality of memory areas is initialized;

executing the first process by using the memory area initialized as the memory area used for executing the first process; and

initializing according to the first information, during the process for rebooting the information processing apparatus, a memory area which is not initialized as a memory area used for executing the second process.

2. The non-transitory computer-readable recording medium according to claim 1, wherein the information processing apparatus further executes:

selecting a memory area used for executing the second process;

initializing the memory area selected by the selecting; and

executing the second process by using the memory area selected by the selecting and initialized by the initializing.

3. The non-transitory computer-readable recording medium according to claim 1, wherein the information processing apparatus further executes:

storing second information in the memory area used for storing the first information, the second information indicating whether the second process is completed; and

initializing according to the first information, when a process for starting the information processing apparatus is executed and the second information indicates that the second process is completed, a memory area which is not initialized.

4. An information processing apparatus which includes a plurality of memory areas and executes a first process and a process for rebooting the information processing apparatus and a second process, the information processing apparatus comprising:

a processor; and

memory storing an instruction for causing the processor to execute;

initializing a memory area of the plurality of memory areas as a memory area used for executing the first process;

storing first information in a memory area, the first information indicating whether each memory area of the plurality of memory areas is initialized;

executing the first process by using the memory area initialized as the memory area used for executing the first process; and

initializing according to the first information, during the process for rebooting the information processing apparatus, a memory area which is not initialized as a memory area used for executing the second process.

5. The information processing apparatus according to claim 4, wherein the processor further executes:

selecting a memory area used for executing the second process;

initializing the memory area selected by the selecting; and

executing the second process by using the memory area selected by the selecting and initialized by the initializing.

6. The information processing apparatus according to claim 4, wherein the processor further executes:

storing second information in the memory area used for storing the first information, the second information indicating whether the second process is completed; and

initializing according to the first information, when a process for starting the information processing apparatus is executed and the second information indicates that the second process is completed, a memory area which is not initialized.

7. A method of controlling an information processing apparatus which includes a plurality of memory areas and executes a first process and a process for rebooting the information processing apparatus and a second process, the method comprising:

initializing a memory area of the plurality of memory areas as a memory area used for executing the first process;

storing first information in a memory area, the first information indicating whether each memory area of the plurality of memory areas is initialized;

executing the first process by using the memory area initialized as the memory area used for executing the first process; and

initializing according to the first information, during the process for rebooting the information processing apparatus, a memory area which is not initialized as a memory area used for executing the second process.

8. The method of controlling the information processing apparatus according to claim 7, the method further comprising:

selecting a memory area used for executing the second process;

initializing the memory area selected by the selecting; and

executing the second process by using the memory area selected by the selecting and initialized by the initializing.

9. The method of controlling the information processing apparatus according to claim 7, the method further comprising:

storing second information in the memory area used for storing the first information, the second information indicating whether the second process is completed; and

initializing according to the first information, when a process for starting the information processing apparatus is executed and the second information indicates that the second process is completed, a memory area which is not initialized.
