BACKGROUND OF THE INVENTION
The present invention relates to an information processing apparatus, and more particularly to an information processing apparatus such as a personal computer or a server.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an information processing apparatus such as a personal computer or a server starts or ends a program including a plurality of resident processes and commands in a predetermined order when the main body starts or ends.
[0003]
Specifically, in the case of termination, the termination process is executed for the first program, and when the program is actually terminated, the termination process is performed for the second program. As described above, the end process is executed for the next program after the program that has been subjected to the end process is actually ended.
[0004]
Japanese Patent Laid-Open No. 2000-194572 has an object to improve the efficiency of automatic job operation by making it possible to recognize the priority of abort processing when a power failure occurs and the operation status information at the time of abort for each job. The automatic job operation method is described.
[0005]
The invention described in the above publication includes job information registration means for registering the end priority, job name, and re-execution necessity information for each job in the job information table during system operation, and UPS at the time of a power failure. During the system shutdown process according to the instruction, job end priority search means for searching the job information table and detecting each execution job in the order of high end priority from the execution job group, and when a power failure occurs, Operation at the time of job termination when it is an execution job detected by the job end priority search means and “re-execution necessity information” is set in the re-execution necessity information in the job information table Registers status information in the job status file, and then cancels the execution status of each execution job. Re-execution job search means for sequentially detecting all re-execution jobs with reference to re-execution necessity information for each job in the job information table, and re-execution detected by the re-execution job search means when the system is restarted. Re-execution job execution means for acquiring operation status information for an execution job from the job operation status file and starting subsequent processing of the re-execution job from the time when the power failure occurred.
[0006]
[Problems to be solved by the invention]
However, in the conventional technology, if the information processing apparatus needs to be terminated urgently and the termination process is performed with the normal termination process, the power is suddenly dropped during the termination process, and the system is destroyed. There is a possibility.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0011]
(Embodiment 1)
[Description of configuration]
FIG. 1 is a block diagram showing a schematic configuration of a part of the information processing apparatus according to the first embodiment of the present invention.
[0012]
FIG. 1 shows a memory 1 that stores various types of information for controlling activation / termination of a plurality of programs including an OS installed in an information processing apparatus, and information stored in the memory 1. The instruction unit 2 for instructing the order of program start / end, the execution unit 3 for executing the start process or the end process of each program in accordance with the instruction from the instruction unit 2, and the user is directed to the instruction unit 2 An input unit 4 for inputting a power ON / OFF instruction and a UPS driver 5 for transmitting a power failure or low battery signal sent from a UPS (not shown) to the instruction unit 2.
[0013]
The memory 1 is like a file including an old instruction memory 11, a new instruction memory 12, a priority information memory 13 and an execution procedure memory 14 which will be described below.
[0014]
The new instruction memory 12 is sent to the storage unit 21 as “start-up”, “normal end”, “end due to power failure”, “end due to low battery”, “power recovery”, “pressing main power by the user” One of the new instructions is stored.
[0015]
The old instruction memory 11 stores an instruction stored in the new instruction memory 12 until the instruction stored in the new instruction memory 12 is updated by the storage unit 21.
[0016]
As will be described later, the instruction stored in the new instruction memory 12 may be rewritten in the old instruction memory 11 once.
[0017]
The priority information memory 13 includes information for determining whether the priority instruction determination unit 22 preferentially executes an instruction stored in the old instruction memory 11 or the new instruction memory 12, and the old instruction memory 11. Information for the execution process determination unit 23 to determine in what procedure the process is executed when the stored instruction is executed with priority is stored.
[0018]
The execution procedure memory 14 stores information to be sent to the activation / termination means 31 according to the determination result of the execution process determination unit 23. Details of the procedure will be described later with reference to FIG.
[0019]
The instruction unit 2 is a program including a storage unit 21, a priority instruction determination unit 22, an execution process determination unit 23, and a reading unit 24 described below.
[0020]
The storage unit 21 stores in the new instruction memory 12 when an instruction indicating that it has been pressed from the main switch of the main body is input, or when an instruction indicating low battery, power failure, or power recovery is input from the UPS. The instruction stored in the new instruction memory 12 until then is stored in the old instruction memory 11 together with the update.
[0021]
The priority instruction determination unit 22 reads each instruction stored in the old instruction memory 11 and the new instruction memory 12 by using a signal transmitted from the storage unit 21 indicating that the instruction has been stored in the old instruction memory 11 as a trigger. The information stored in the memory 13 such as the priority information based on those instructions is referred to, and it is determined whether the instruction stored in the old instruction memory 11 or the new instruction memory 12 is to be executed with priority. It is.
[0022]
As a result of the determination by the priority instruction determination unit 22, the execution process determination unit 23 specifically determines in what procedure the process is executed when the instruction stored in the new instruction memory 12 is executed with priority. It is to be determined.
[0023]
The reading unit 24 reads information stored in the execution procedure memory 14 according to the determination result of the execution process determination unit 23 and sends the information to the execution unit 3.
[0024]
The execution unit 3 is a program including a plurality of start / end processing means 31 described below.
[0025]
The activation / termination means 31 is prepared for each program installed in the information processing apparatus main body, for example, and is driven according to the information sent from the reading unit 24.
[0026]
FIG. 2 is a conceptual diagram of information stored in the priority information memory 13 shown in FIG.
[0027]
FIG. 2 shows that the old instruction memory 11 and the new instruction memory 12 are terminated by “low battery”, “main switch OFF” by the user, “power failure”, “power recovery”, “normal termination”, and “activation”. When an instruction is stored, it indicates which of the instructions stored in the old instruction memory 11 and the new instruction memory 12 is prioritized and what processing is actually executed. Is.
[0028]
Note that “◯” shown in FIG. 2 executes the instruction stored in the new instruction memory 12 in preference to the instruction stored in the old instruction memory 11, and “×” is stored in the old instruction memory 11. This indicates that the instruction being executed is prioritized over the instruction stored in the new instruction memory 12. Further, as described in the second embodiment with respect to “Δ”, one of the instructions stored in the old instruction memory 11 and the new instruction memory 12 is preferentially executed according to the remaining battery capacity of the UPS. Is shown.
[0029]
Specifically, for example, when an instruction to terminate due to “power failure” is stored in the old instruction memory 11 and an instruction to terminate due to “low battery” is stored in the new instruction memory 12, the instruction is stored in the new instruction memory 12. The instruction is executed in preference to the instruction stored in the old instruction memory 11. At that time, the process actually executed is a process called “P1” described later.
[0030]
For example, when an instruction to end due to “low battery” is stored in the old instruction memory 11 and an instruction to end due to “power failure” is stored in the new instruction memory 12, the instruction stored in the old instruction memory 11 is changed to The instruction is executed with priority over the instruction stored in the new instruction memory 12.
[0031]
Here, the processes shown in “P1” to “P3” have the following contents, for example. In other words, “P1” is the one that needs to complete the program termination process earliest among “P1” to “P3”, and among all the running programs, the resident program and the non-resident program are collectively terminated. Or, it is finished in a manner close to that (for example, it is finished every about 5 seconds for each of these programs sequentially). Then, the OS is terminated.
[0032]
“P2” requires that program termination processing be completed early after “P1”. For example, a resident program such as a communication program or a program having a high dependency among a plurality of programs. On the other hand, a program related to a monitoring service for a peripheral device such as a schedule service, a business service, or a printer among the resident programs is terminated by issuing a termination command to the next program after the program that issued the termination command first. Is finished in a batch or close to it. Then, the OS is terminated.
[0033]
“P3” requires that the program end process be completed early after “P2”. For resident programs, the end of the program that issued the end command first depends on the number of running programs. The program is terminated later by issuing an end command to the next program, and the other programs are terminated in a batch manner or in a manner close thereto. Then, the OS is terminated.
[0034]
When a normal end instruction is issued, the process is terminated by issuing an end instruction to the next program after the end of the program that has issued the end instruction for all the programs that are running. Then, the OS is terminated.
[0035]
Further, in the present embodiment, the programs having high dependency among the programs are grouped, and they are terminated in a required procedure. Specifically, for example, a connection program for connecting to the Internet and a communication program for sending and receiving mail via the Internet are highly dependent on each other, so they are placed in the same group and the communication program is terminated. The connection program is terminated after completion.
[0036]
This means that even if a “power failure” occurs during the actual transmission of an email, it will wait for the completion of the email transmission and issue an instruction to terminate the communication program so that the email can be sent properly. Thus, after the communication program end processing is completed, an end command can be issued to the connection program.
[0037]
FIG. 3 is an explanatory diagram of grouping for programs that are highly dependent on each other. As shown in FIG. 3, the programs are classified into resident programs, non-resident programs, and OSs.
[0038]
The resident programs are broadly divided into communication services, schedule services, and peripheral device monitoring services.
[0039]
[Description of operation]
FIG. 4 is a flowchart showing the operation of FIG. First, when an instruction to start or end is input from the input unit 4 to the instruction unit 2 or an instruction such as “power failure” is input from the UPS driver 5, the storage unit 21 stores the instruction in a new instruction memory. 12 and the instruction previously stored in the new instruction memory 12 is transferred to the old instruction memory 11 (step S1).
[0040]
When the storage of the instruction in the old instruction memory 11 is completed, a signal indicating that is output to the priority instruction determination unit 22 (step S2).
[0041]
The priority instruction determination unit 22 reads each instruction stored in the old instruction memory 11 and the new instruction memory 12 using a signal from the storage unit 21 as a trigger, and stores it in the memory 13 such as priority information based on those instructions. With reference to certain information, it is determined whether or not the instruction stored in the old instruction memory 11 is to be executed with priority. The determination result is sent to the execution process determination unit 23 (step S3).
[0042]
As a result of the determination, when the instruction stored in the new instruction memory 12 is to be executed with priority, the execution process determining unit 23 is activated (step S4).
On the other hand, when the instruction stored in the old instruction memory 11 is preferentially executed as a result of the determination, the instruction stored in the old instruction memory 11 is rewritten in the new instruction memory 12 in the storage unit 21. The process shown in FIG. 2 is terminated (step S5).
[0043]
The execution process determination unit 23 refers to the priority information memory 13 and specifically determines which of the processes “P1” to “P3” is to be executed, and sends the determination result to the reading unit 24 (Step S1). S6).
[0044]
The reading unit 24 reads the information stored in the execution procedure memory 14 according to the determination result of the execution process determination unit 23, and sends the information to the execution unit 3 (step S7).
[0045]
The execution unit 3 executes the process according to the determined procedure by driving the required start / end means 31 in accordance with the information sent from the reading unit 24 (step S8).
[0046]
Next, as a specific example, an operation when a power failure occurs during startup of the information processing apparatus will be described.
[0047]
First, a “power failure” instruction is input from the UPS driver 5 to the instruction unit 2, and the storage unit 21 stores the instruction in the new instruction memory 12 and has been stored in the new instruction memory 12 until then. The “startup” instruction is transferred to the old instruction memory 11 (step S1).
[0048]
When the storage of the instruction in the old instruction memory 11 is completed, a signal indicating that is output to the priority instruction determination unit 22 (step S2).
[0049]
The priority instruction determination unit 22 reads each instruction of “startup” and “power failure” stored in the old instruction memory 11 and the new instruction memory 12 using a signal from the storage unit 21 as a trigger, and performs priority based on these instructions. Information stored in the information memory 13 is referred to.
[0050]
Here, as shown in FIG. 3, when the instructions “startup” and “power failure” are stored in the old instruction memory 11 and the new instruction memory 12, the “power failure” stored in the new instruction memory 12 is stored. "Is preferentially executed, and the determination result is sent to the execution process determination unit 23 (step S3).
[0051]
In addition, since the instruction stored in the new instruction memory 12 is executed with priority, the execution process determination unit 23 is activated (step S4).
The execution process determination unit 23 refers to the priority information memory 13 and determines that the process of “P3” is specifically executed, and sends the determination result to the reading unit 24 (step S6).
[0052]
The reading unit 24 reads the information stored in the execution procedure memory 14 according to the determination result of the execution process determination unit 23 and sends the information to the execution unit 3 (step S7).
[0053]
Here, the information regarding “P3” stored in the execution procedure memory 14 is, for example, “for a resident program, it ends by issuing an end instruction to the next program after the end of the program that previously issued the end instruction, Other programs are terminated in a batch manner or close to it. Then, the execution unit 3 starts the first start / end means 31 related to the resident program, and when the program actually ends, the second start / end means 31 is executed. Is activated.
[0054]
In this way, when the activation / termination means 31 relating to all the resident programs are activated, when each resident program is terminated, the activation / termination means 31 relating to the OS is activated, and finally all the programs are terminated.
[0055]
(Embodiment 2)
[Description of configuration]
FIG. 5 is a block diagram illustrating a schematic configuration of a part of the information processing apparatus according to the second embodiment of the present invention. In this embodiment, whether or not the “power failure” is restored when the user gives an instruction for “startup” when the program is terminated or after it is terminated due to “power failure” or “low battery” If it has not been recovered, the startup process is stopped.
[0056]
The confirmation unit 25 shown in FIG. 5 is for confirming whether or not a power failure still continues and confirming the current remaining battery level. In FIG. 5, the same parts as those shown in FIG.
[0057]
[Description of operation]
FIG. 6 is a flowchart showing the operation of FIG. 5 when a “start” instruction is given by the user.
[0058]
First, when a “startup” instruction is input from the input unit 4, the OS is started, and the instruction unit 2 refers to the new instruction memory 12 by the confirmation unit 25 (step S 11).
[0059]
Then, it is determined whether or not the instruction stored in the new instruction memory 12 is “normal end” (step S12).
[0060]
As a result of the determination, if the instruction stored in the new instruction memory 12 is “normal end”, the resident program is activated (step S14).
[0061]
On the other hand, as a result of the determination, if the instruction stored in the new instruction memory 12 is not “normal end”, the confirmation unit 25 confirms the remaining battery level on the UPS driver 5 side (step S13).
[0062]
In this way, it is determined whether or not the battery level is sufficient to activate the resident program or the like, that is, whether or not the resident program or the like can be restored (restarted) (step S15).
[0063]
If it is determined that the resident program can be restored, the resident program is activated (step S14).
[0064]
On the other hand, if it is determined that the resident program or the like cannot be recovered, the activation process of the resident program or the like is stopped (step S16).
[0065]
As described above, in this embodiment, if the power is restored or the remaining battery level is not sufficient to restore the program, the activation of the resident program is stopped and the resident program is forcibly terminated again. I'm trying not to get it.
[0066]
【The invention's effect】
As described above, according to the present invention, an end request can be issued to each running program by an end instruction based on the priority order, and the end request is issued each time a power state is input. Since the priority order for performing the process can be updated, the control for terminating each program can be performed accurately, and the data related to the program to be terminated and the information processing apparatus can be reliably protected.
