BACKGROUND OF THE INVENTION
The present invention relates to a stop of a computer system, and more particularly to a computer system automatic stop device for stopping a computer system using an automatic shutdown device.
[0002]
[Prior art]
A block diagram of a conventional computer system automatic stop device is shown in FIG.
[0003]
The user sets the system stop time for the automatic shutdown apparatus 3 in advance by the system stop time setting means 11 provided in the server 1. When the system stop time comes, the automatic shutdown device 3 issues a shutdown request to the server shutdown unit 12 of the server 1. Upon receiving the shutdown request, the server shutdown unit 12 issues a shutdown request to the client shutdown units 5-11 to 5-N1 of the clients 5-1 to 5-N.
[0004]
Each of the client shutdown units 5-11 to 5-N1 starts a shutdown operation when receiving a shutdown request. The server shutdown unit 12 also performs its own shutdown operation after making a shutdown request to the client shutdown unit 5-11 to 5-N1, but the shutdown operation is terminated immediately before the shutdown operation process is completed. The automatic shutdown device 3 is notified via the server shutdown end notification means 13 to end the shutdown operation. When the automatic shutdown device 3 receives the notification of the shutdown completion, the automatic shutdown device 3 shuts off the power of the clients 5-1 to 5-N and the server 1.
[0005]
In this way, the computer system automatic stop device by the conventional automatic shutdown device is the computer shutdown operation, and the computer to which the automatic shutdown device is connected is directly operated by the command from the automatic shutdown device, and the automatic shutdown device is connected In the case of a computer that has not been set, this is performed by a shutdown request notified through the computer to which the automatic shutdown device is connected.
[0006]
[Problems to be solved by the invention]
However, in the conventional computer system automatic stop device, when any processing is executed on the computer immediately before the system stop time, for example, the user writes or updates data without noticing the system stop time. In this case, there is a possibility that the writing / updating process is interrupted in the middle due to the system stop, and there is a concern that not only the user's work is suddenly interrupted but also the data consistency is impaired.
[0012]
  Therefore, the present inventionFirstAn object of the present invention is to provide a computer system automatic stop device capable of notifying a user using a computer that the system stop time has come and delaying the system stop by a desired time.
[0013]
In addition, in the conventional computer system automatic stop device, the server did not confirm whether the client is activated or stopped, and requested a shutdown, so if the client has already stopped, the shutdown request is not accepted, It took time for the server to recognize this, and it took extra time to stop the system. In addition, because the server shuts down without confirming that the client has stopped, the server stops before the client, and the processing that is being executed using the server resources on the client is interrupted, resulting in data consistency. There was a risk of damage.
[0016]
  Therefore, the present inventionSecondAn object of the present invention is to provide a computer system automatic stop device that can be shut down after processing that should not be forcibly terminated in the middle is normally terminated in a predetermined order.
[0023]
[Means for Solving the Problems]
  The computer system automatic stop device of the present invention includes an automatic shutdown device that requests a shutdown at the system stop time, a system stop time setting unit that notifies the automatic shutdown device of a system stop time set by the user, and a shutdown from the automatic shutdown device. A server computer having server shutdown means for receiving a request and shutting itself down at the system stop time, and at least one client computer having client shutdown means for receiving a shutdown request from the server computer and shutting itself down at the system stop time The system stop notification means for notifying the system stop when the server computer receives a shutdown request from the automatic shutdown device, and the system After the system stop notification is input from the stop notification means, the delay time of the system stop time is input from the user, the server delay time setting means for notifying this delay time, and the delay time and the delay time input from the client computer A delay request receiving means for delaying the shutdown until the longest delay time that is longer than a predetermined system stop time cannot be set, and the client computer stops the system from the system stop notification means. After the notification is input, a delay time of the system stop time is input from the user, and client delay time setting means for notifying this delay time to the delay request receiving means is provided.
[0024]
As described above, when the server receives a shutdown request from the automatic shutdown apparatus, the system stop notification means notifies the server delay time setting means and the client delay time setting means that the system is to be stopped. Upon receiving this notification, each delay time setting means notifies the delay request accepting means of the accepting server from the user of the time for which the system stop is to be delayed. The delay request accepting unit waits for the predetermined longest time of the notified delay time to elapse, and notifies the server shutdown unit to shut down after the delay time elapses.
[0025]
As a result, it becomes possible for the user who is using the computer at the system stop time to delay the stop of the system, and it is possible to avoid the risk of the loss of data consistency due to the shutdown.
[0029]
  The computer system automatic stop device of the present invention requests a shutdown at the system stop time.Automatic shutdown device and automatic shutdown deviceA server computer having server shutdown means for receiving a shutdown request from the server computer and shutting itself down at the system stop time, and at least client shutdown means for receiving a shutdown request from the server computer and shutting itself down at the system stop time With one client computer,The server computer is in operationWhen the server program storage means storing the programs in sequence and the server shutdown means receive a shutdown request, the server program storage means confirms the operating program and issues an end command to the programs in order. Server program operation confirmation means to terminateAnd the client computer is operating.When the client program storage means storing the programs in order and the client shutdown means receive a shutdown request, the client program storage means confirms the program in operation and issues an end command to the programs in order. Client program operation confirmation meansThe client shutdown unit shuts down the client computer after the program being operated is terminated by the client program operation confirmation unit, and the server shutdown unit is configured to shut down the client computer by the client shutdown unit. When the shutdown is performed, a confirmation request is sent to the server program operation confirmation unit, and the server computer is shut down after the running program is terminated by the server program operation confirmation unit.
[0030]
As described above, when the shutdown operation starts, the server program operation confirmation means confirms whether a program stored in the server program storage means that should not be forcibly terminated is operating. An end command is issued to the program in the stored order, and the end of the program is confirmed to shut down.
[0031]
As a result, it is possible to avoid the risk that the program is forcibly terminated during execution and the consistency of the data is lost, or the termination order is reversed and the processing necessary for the system cannot be performed.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0033]
A block diagram of FIG. 1 shows an embodiment of the computer system automatic stop device of the present invention.
[0034]
In FIG. 1, an automatic shutdown device 3 is connected to a server 1, and the server 1 includes a system stop time setting unit 11, a server shutdown unit 12, a system stop time notification unit 20, a server system stop display unit 21, a prior notification unit 23, and The prior notification time storage unit 24 is included, and each of the clients 5-1 to 5-N includes client system stop display units 5-12 to 5-N2.
[0035]
Here, the operation of the present embodiment will be described with reference to the flowchart of FIG.
[0036]
In the server 1, it is determined whether or not a system stop time is newly set by the user in the system stop time setting means 11 (step 200). If the system stop time is set, the system stop time setting means 11 automatically The system shutdown time is notified to the shutdown device 3 to cause the automatic shutdown device 3 to set this time. If it is not set, the routine goes to Step 205 (Step 201).
[0037]
Next, the system stop time setting means 11 notifies the server system stop display means 21 and the client system stop display means 5-12 to 5-N2 via the system stop time notification means 20 (step 202). 203). The server system stop display means 21 and the client system stop display means 5-12 to 5-N2 display the system stop time (step 204).
[0038]
The advance notification means 23 always calculates the remaining time from the current time to the system stop time (step 205), and compares the remaining time with the advance notification time stored in advance in the advance notification time storage means 24. (Step 206) When the remaining time becomes equal to or shorter than the prior notification time, the remaining time is notified to the server system stop display means 21 and the client system stop display means 5-12 to 5-N2 (Step 207). Upon receiving this notification, the server system stop display means 21 and the client system stop display means 5-12 to 5-N2 display the remaining time until the system stop time.
[0039]
Thus, the system stop time set by the system stop time setting means 11 is notified to the server 1 and the clients 5-1 to 5-N via the system stop time notifying means 20, and the server system stop time is notified. By displaying the display means 21 and the client system stop display means 5-12 to 5-N2, the user using the server 1 and the clients 5-1 to 5-N can always recognize the system stop time. Become.
[0040]
Further, when the remaining time until the system stops becomes equal to or less than the time previously stored in the prior notification time storage unit 24, the prior notification unit 23 and the server system stop display unit 21 and the client system stop display units 5-12 to 5-N2 Is notified of the remaining time, and the remaining time is displayed by the server system stop display means 21 and the client system stop display means 5-12 to 5-N2.
[0041]
For this reason, the user who uses the server 1 and the clients 5-1 to 5-N can end the process being executed before the system is stopped. In addition, it is possible to avoid the risk that the computer shuts down due to not knowing the system stop time and the data integrity is lost.
[0042]
Another embodiment of the computer system automatic stop device according to the present invention is shown in the block diagram of FIG.
[0043]
In FIG. 3, the server 1 connected to the automatic shutdown device 3 includes a system stop time setting unit 11, a system stop time receiving unit 30, a system stop time storage unit 31, and a system stop time non-settable time storage unit 32. The clients 5-1 to 5-N include system stop time setting notification units 5-13 to 5-N3.
[0044]
The operation of this embodiment is shown in the flowchart of FIG. When the user inputs the system stop time in any of the clients 5-1 to 5-N (step 401), the client system stop time setting notifying unit 5-13 to 5-N3 input by the user inputs this input. Is notified to the system stop time reception means 30 of the server 1 (step 402).
[0045]
The system stop time reception means 30 determines whether another system stop time is already set in the system stop time storage means 31 and the system stop time input by itself is later than the stored system stop time. Judgment is made (step 403).
[0046]
If so, the system stop time reception means 30 notifies the system stop time setting means 11 of the notified system stop time (step 405).
[0047]
On the other hand, if the notified system stop time is earlier than the system stop time stored in the system stop time storage means 31, or if the system stop time is not stored in the system stop time storage means 31, the system stop time reception means 30 determines whether the notified system stop time falls between the current time and the system stop time non-setting time stored in the system stop time non-setting time storage means 32 (step 404). When the system stop time falls within the system stop time setting impossible time, the system stop time receiving means 30 notifies the clients 5-1 to 5-N that the system stop time cannot be set (step 408).
[0048]
If the notified system stop time does not fall within the system stop time non-settable time, the system stop time accepting unit 30 notifies the system stop time setting unit 11 of the system stop time notified from the client (step 405). When the system stop time is received from the system stop time receiving means 30, the system stop time setting means 11 sets the system stop time in the automatic shutdown device 3 (step 406) and stores it in the system stop time storage means 31 (step 406). Step 407).
[0049]
In this way, not only the server 1 but also the clients 5-1 to 5-N can set the system stop time. Further, in order to prevent the system stop time that has already been set from being advanced or set between the current time and the time stored in the system stop time non-settable time storage means on the client side, the user using the client It is possible to avoid the risk of sudden system shutdown by advancing the system stop time without considering the state of the entire system.
[0050]
Another embodiment of the computer system automatic stop device of the present invention is shown in the block diagram of FIG.
[0051]
5, the server 1 connected to the automatic shutdown device 3 includes a server shutdown unit 12, a system stop notification unit 40, a server delay time setting unit 41, a delay request reception unit 42, a delay request reception time storage unit 43, and An upper limit delay time storage unit 44 is included, and the clients 5-1 to 5-N include client delay time setting units 5-14 to 5-N4.
[0052]
The flow of processing of this embodiment is shown in the flowchart of FIG.
[0053]
When the preset system stop time is reached, the automatic shutdown device 3 issues a shutdown request to the server 1 (step 601). The server shutdown unit 12 that receives the shutdown request requests the system stop notification unit 40 to stop the system (step 602). Upon receiving this request, the system stop notification means 40 notifies the server stop time to the server delay time setting means 41, the delay request reception means 42, and the client delay time setting means 5-14 to 5-N4 (step 603). .
[0054]
The server delay time setting means 41 and the client delay time setting means 5-14 to 5-N4 accept the time (delay time) to be delayed from the user when the user wants to delay the system stop time, and this delay time. Is sent to the delay request receiving means 42 of the server 1 (step 604).
[0055]
When the system stop notification is notified from the system stop notification unit 40, the delay request reception unit 42 receives the server delay time setting unit 41 until a predetermined delay request reception time stored in advance in the delay request reception time storage unit 43 elapses. The delay time is received from the client delay time setting means 5-14 to 5-N4 (step 605).
[0056]
If there is no notification of the delay time after the delay request reception time has elapsed, the delay request reception means 42 notifies the server shutdown means 12 to shut down (steps 606 and 610).
[0057]
On the other hand, if there is a notification of the delay time, the delay request receiving means 42 has the longest delay that is equal to or shorter than the predetermined upper limit delay time stored in advance in the upper limit delay time storage means 44 among the received delay times. Wait until the time has elapsed (steps 606, 607, 609).
[0058]
When all the notified delay times exceed the time stored in the upper limit delay time storage unit 44, the delay request reception unit 42 passes the upper limit delay time stored in the upper limit delay time storage unit 44. (Steps 606, 607, and 608).
[0059]
Thereafter, the delay request receiving means 42 notifies the server shutdown means 12 of the server 1 to perform shutdown (step 610).
[0060]
As described above, before the server shutdown unit executes the shutdown, the server delay time setting unit and the client delay time setting unit allow the user to set the delay time that the user wants to delay the system stop. It is possible to avoid a risk that the processing being executed is forcibly terminated and the data consistency is impaired.
[0061]
Another embodiment of the computer system automatic stop device of the present invention is shown in the block diagram of FIG.
[0062]
In FIG. 7, the server 1 connected to the automatic shutdown apparatus 3 includes a server shutdown unit 12, a client activation confirmation unit 50, a client activation status storage unit 51, and a client activation status setting cycle storage unit 52. 1-N includes client shutdown means 5-11 to 5-N1 and client activation status setting means 5-15 to 5-N5.
[0063]
Here, the configuration of the client activation status storage unit 51 will be described with reference to FIG.
[0064]
The client activation status storage unit 51 has N flags corresponding to the clients 5-1 to 5-N. Each flag represents the activation status of the client. For example, the flag has a value of “0” if the client is in a stopped state and “1” if the client is in an activated state.
[0065]
The processing of this embodiment is shown in the flowchart of FIG.
[0066]
When the server 1 starts up, the client activation confirmation unit 50 of the server 1 sets “0” (stop) to initialize each flag of the client activation state storage unit 51 (step 901).
[0067]
When the clients 5-1 to 5 -N start up, the client activation status setting means 5-15 to 5 -N 5 have the predetermined period stored in advance in the client activation status setting period storage means 52 of the server 1. The client activation status storage unit 51 is monitored and the corresponding flag is set to “1” (activation) (step 902).
[0068]
When the system stop time is reached, the server 1 receives a shutdown request from the automatic shutdown device 3, and the server shutdown unit 12 requests the client activation confirmation unit 50 to confirm the activation suspension status of each of the clients 5-1 to 5-N ( Step 903).
[0069]
Upon receiving this request, the client activation confirmation unit 50 sets each flag of the client activation status storage unit 51 to “0” (stop) (step 904).
[0070]
Thereafter, the client activation confirmation unit 50 waits for one cycle of the period stored in the client activation state setting period storage unit 52 (step 905).
[0071]
After the time of one cycle has elapsed, the client activation confirmation unit 50 determines that the flag is “1” (if the flag of “1” (activation) is one or more of the flags in the client activation status storage unit 51 ( The server shutdown unit 12 is notified of the activated client (steps 906 and 907).
[0072]
The server shutdown unit 12 requests the notified client to shut down, and requests the client activation confirmation unit 50 again to confirm the client start / stop status (step 908).
[0073]
When this procedure is repeated and the client activation confirmation unit 50 confirms that all the flags in the client activation status storage unit 51 are “0” (stopped), the server shutdown unit 12 performs server shutdown (steps 906 and 909). ).
[0074]
As a result, it is possible to eliminate the time for the server to recognize that the shutdown request is not accepted by the client, and it is possible to efficiently stop the system. Furthermore, it is possible to avoid the risk that the server stops before the client stops, or the processing executed by using the server resources on the client is interrupted, and the data integrity is impaired.
[0075]
Another embodiment of the computer system automatic stop device of the present invention is shown in the block diagram of FIG.
[0076]
In FIG. 10, the server 1 connected to the automatic shutdown apparatus 3 includes a server shutdown unit 12, a server program operation confirmation unit 60, and a server program storage unit 61. The clients 5-1 to 5-N are client shutdowns. Means 5-11 to 5-N1, client program operation confirmation means 5-16 to 5-N6, and client program storage means 5-17 to 5-N7.
[0077]
The processing flow of this embodiment is shown in the flowchart of FIG.
[0078]
When the server 1 receives a shutdown request from the automatic shutdown device 3 (step 110), the server shutdown unit 12 notifies the shutdown request to the client shutdown unit 5-11 of the first (= N) client 5-1, for example. (Steps 111 and 112).
[0079]
The client shutdown unit 5-11 requests the client program operation confirmation unit 5-16 to confirm whether or not a program that should not be forcibly terminated is in operation (step 114).
[0080]
The client program operation confirmation means 5-16 reads the program name to be confirmed from the client program storage means 5-17 managing the program being operated in its own computer (step 115), and is it operating? It is confirmed whether or not (step 116).
[0081]
If there is an operating program, an end command is issued to the program (steps 117 and 118). Thereafter, an end command is issued to each of the operating programs in the order in which they are stored in the client program storage unit 5-17 (steps 116, 117, 118). When there is no program in operation, the program itself is shut down as it is (step 119).
[0082]
The above operation is performed for all clients (steps 120 and 113). When all the clients have been shut down, the server shutdown unit 12 requests the server program operation confirmation unit 60 to confirm whether a program that should not be forcibly terminated is in operation (step 121).
[0083]
The server program operation confirmation means 60 sequentially reads the names of the programs being operated from the server program storage means 61 (step 122), and confirms whether this program is operating (step 123).
[0084]
If it is operating, it issues an end command to the program (steps 124 and l25), and issues an end command to other programs that are operating in the order stored in the server program storage means 61. .
[0085]
If there is no program in operation, the program itself is shut down as it is (step 126).
[0086]
In this way, the program operation confirmation means confirms whether a program stored in the program storage means that should not be forcibly terminated is operating, and if it is in operation, issues an end command in the order stored in the program storage means. By confirming the end of the program and shutting down, it is possible to avoid the risk that the program will be forcibly terminated during execution and data consistency will be lost, or the order of termination will be reversed and the system will not be able to perform necessary processing .
[0089]
【The invention's effect】
  According to the present invention,A user who uses a computer can delay the system stop even when the system stop time is reached, thereby avoiding the risk that the process being executed at the system stop time is forcibly terminated due to the shutdown and the data integrity is impaired. it can.
[0091]
According to the present invention, a program that should not be forcibly terminated can be shut down after being normally terminated in a predetermined order, the program is forcibly terminated and data integrity is lost, or the order of termination is reversed. Therefore, it is possible to avoid the risk that the necessary processing cannot be performed as a system.
