TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and an apparatus suitable for use in a data processing device for confirming operation after replacement of a load module in which a defect has been corrected in application software or an operating system, which is suitable for a data processing device.
[0002]
[Prior art]
Application software and operating systems (hereinafter abbreviated as OS) running on data processing devices often have defects. Therefore, the replacement is performed with the load module in which the defect is corrected by the installer or the like attached to the software.
However, it is necessary to confirm on the system whether the corrected load module operates normally. Here, when the replacement with the corrected load module fails, or when the corrected load module has a new defect (degradation), the recovery work may be extremely troublesome.
[0003]
[Problems to be solved by the invention]
As described above, conventionally, in the operation check of the corrected load module, the man-hour required when the replacement fails is large, and is particularly remarkable when the corrected load module has a problem. The reason is that if the replacement of the corrected load module fails or if there is a new defect in the load module, the application software or OS may not start. In this case, the installer prepared for each software may be used. This is because it is necessary to perform recovery using, and in some cases, to perform reinstallation.
In particular, if there is a new defect in the corrected load module, it can be confirmed that the software operates normally after replacement without actually using the corresponding application software or OS. High.
The present invention has been made in view of the above circumstances, and performs time-based startup monitoring in a restart after a corrected load module replacement, and as a result of the startup monitoring, a load that has been corrected when a failure is detected. By constructing a mechanism that automatically recovers to the state before replacing the module, the startup confirmation work and the recovery work after replacing with the modified load module were reduced, and the burden on the user or maintenance person was reduced. An object of the present invention is to provide a recovery method and device after replacement of a modified load module.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a restoration method after replacement of a corrected load module according to claim 1 is a data processing apparatus for confirming operation after replacement of a load module whose application software or operating system has been corrected. After evacuating the defective load module, replacing the load module with the corrected defect and restarting the application program or the operating system.At the time of this restart, by monitoring the startup time, When the start failure is confirmed, the load module is restored to the evacuated load module before the defect correction, the start processing is divided into arbitrary processing units, and the monitoring start time is processed for each processing unit prior to the start processing. At the end of the process, each end time is registered in the storage device. After the elapse of the standby time necessary for the start stored in advance from the registered monitoring start time, it is determined whether or not each start process has been completed by referring to the storage device. The feature is to recover the module .
[0005]
The restoration method after replacement of the modified load module according to claim 2 is the method according to claim 1 , wherein the restoration to the load module before the correction of the defect is performed by the application software or the operating system after the replacement of the modified load module. When the restart is confirmed by the start monitoring based on the time to indicate that the start has failed, the state before the correction is replaced by replacing the load module before the correction already saved with the corresponding load module after the correction. Is restored.
[0006]
The recovery device after the replacement of the modified load module according to claim 3 is a data processing device for performing an operation check after the replacement of the load module whose application software or the operating system has been subjected to the defect correction. A modified load module replacing means for replacing the module with the corrected load module and recording information indicating the replacement in a storage device as a monitoring identification flag; and Monitoring time registering means for registering the start time and the end time of the storage device when restarting, and monitoring the time by holding the required time required for the start in advance and referring to the flag information After replacing the load module When it is confirmed that the application software or the operating system to be monitored has been started by referring to the storage device after waiting for a predetermined time required for the start from the start time of the start, and confirming that the start of the application software or the operating system has been completed. A boot monitoring means for confirming whether or not the boot has been failed by the boot monitoring by restarting the application software or the operating system after the replacement of the corrected load module; Modified load module restoring means for restoring the state before correction by replacing the load module with the corresponding modified load module, and monitoring start time prior to the start processing for each start processing unit divided into arbitrary processing units When the processing is completed, the respective end time is stored in the storage device. A monitoring start / end time registration unit to be registered; and an application to be monitored by referring to the storage device after a lapse of a standby time required for each activation processing unit stored in advance from the registered monitoring start time. A boot monitoring unit configured to determine whether each boot process of the program or the operating system is completed .
[0007]
In the above-described configuration, regarding the operation check after replacing the defective OS and the application software with the load module having the defect corrected, the startup monitoring is performed when the OS and the application software are started, and the malfunction such as a stall is detected. Is automatically restored to the load module before replacement. As a result, it is possible to reduce the man-hour for the start-up confirmation work after replacing the load module with the corrected load module. Since the state before the replacement is automatically restored, the burden on the restoration work is reduced.
[0008]

FIG. 1 is a block diagram showing one embodiment of the present invention. The recovery device after replacement of the modified load module according to the present invention includes a storage unit 1 in which data files and program files are stored, a data processing device 2 that performs processing under control of a program, and an output device 3 that outputs an execution result. And Note that a program for controlling the data processing device 2 is stored in the storage device 1 as a program file.
[0009]
The storage device 1 includes a monitoring identification flag storage unit 11 that stores information for identifying whether or not monitoring is required by application software or an OS to be monitored, and a monitoring start time and a start time when monitoring is performed. A time storage unit 12 for storing information for identifying whether or not the processing has been completed, and a time required for activating the application software or OS to be monitored (a time after which the activation can be determined to be abnormal). A standby time storage unit 13, a software load module group 14 storing application software and a load module of the OS itself (indicated by a load module in the figure), and a software load module before replacing with a corrected load module A load module in which the load module to be replaced is saved from the load module group 14 Yuru including retraction load modules 15 are stored.
[0010]
The data processing device 2 includes a monitoring start time registration unit 21, a monitoring end time registration unit 22, a startup monitoring unit 23, a save load module restoration unit 24, and a modified load module replacement unit 25. The monitoring start time registration means 21 and the monitoring end time registration means 22 are included in the application software or the OS itself, and perform processing at the time of startup. The start monitoring unit 23, the save load module restoring unit 24, and the modified load module replacing unit 25 are included in load module replacing software such as an installer prepared by each software.
The functions and operations of the above-described units are as follows.
[0011]
The monitoring start time registration unit 21 is included in the monitoring target application software or the OS, and stores the start start time in the time storage unit 12 when each software is started. The monitoring end time registration unit 22 is included in the monitoring target application software or the OS, and stores the information indicating the end in the time storage unit 12 when the activation of each software ends.
The startup monitoring unit 23 refers to the monitoring identification flag storage unit 11 and determines whether startup monitoring is necessary. When monitoring is necessary, the start time of the application software or the OS stored in the time storage unit 12 and the wait time stored in the standby time storage unit 13 are referred to, and the wait time elapses from the start time. And the time storage unit 12 is referred to when the time has elapsed. If the time storage unit 12 has a flag indicating the end of application or OS startup, the result of the normal function is output to the output device 3. If there is no flag indicating the end of the application software or OS startup in the time storage unit 12, it is determined that the startup has failed, and the control is transferred to the save load module recovery unit 24.
The save load module group restoring unit 24 replaces the load module stored in the save load module group 15 with a corresponding load module in the software load module group 14 and outputs a processing result to the output device 3. The modified load module replacing means 25 replaces a defective load module in the software load module group 14 with a corrected load module. At the time of replacement, the fact that the load module has been replaced is stored in the monitoring identification flag storage unit 11.
[0012]
FIGS. 2 to 4 are flowcharts cited for explaining the operation of the embodiment of the present invention shown in FIG. 1. The basic operation of the modified load module restoring device of the present invention as a whole and the start monitoring unit 23 are respectively shown. The operation procedure of the save load module restoring means 24 will now be described. Hereinafter, the operation of the embodiment of the present invention shown in FIG. 1 will be described in detail with reference to FIGS.
[0013]
First, an operation from replacing a defective load module with a corrected load module to confirming activation of application software or an OS will be described with reference to a flowchart shown in FIG. First, the corrected load module replacing means 25 saves the defective load module in the software load module group 14 to the evacuation load module group 15 and then replaces the corrected load module with the defective load module to load the defective load module. Information indicating that the module has been replaced is stored in the monitoring identification flag storage unit 11 (step A1 in FIG. 2).
Next, the application software or the OS is restarted to confirm the corrected start-up (step A2). When starting, the monitoring start time registration procedure 21 causes the time storage unit 12 to store the start start time (step A3), and the monitoring start time registration means 21 determines which application or OS is running the start monitoring means 23. The process is started as another process (step A4). The application software or the OS performs a start-up process (step A5). After the start-up is completed (step A6), in step A7, the monitoring end time registration unit 22 stores information indicating that the start-up is completed in the time storage unit 12. Is stored.
[0014]
Next, the operation of the activation monitoring means 23 in which the application software or the OS has started the operation in step A4 shown in FIG. 2 will be described with reference to the flowchart shown in FIG. First, referring to the monitoring identification flag storage unit 11, it is confirmed whether or not the activation is performed after the replacement of the load module (step B1 in FIG. 3). Then, the monitoring identification flag storage unit 11 is initialized, and information indicating that the activation is performed after the replacement of the load module is deleted (step B2). As a result of the confirmation in step B1, if the activation is not the activation after the replacement of the load module, the monitoring is not performed and the operation ends. If the activation is the activation after the replacement of the load module, the standby time is calculated from the activation start time stored in the time storage unit 12. The activation monitoring unit 23 waits until the time required for activation stored in the storage unit 13 elapses (step B4).
After waiting for a predetermined time, it refers to the time storage unit 12 to check whether the activation of the application software or the OS to be monitored has been completed (step B5). If it has been started normally, the fact that it has been started normally is output to the output device 3 in the restart after replacement of the load module (step B8). If it has not been started normally, the load module is replaced. In order to return to the previous state, the processing of the evacuation load module restoration means 24 is started (step B7).
[0015]
Finally, the operation of the save load module restoration means 24 will be described with reference to the flowchart shown in FIG. The save load module restoring means 24 outputs to the output device 3 that the startup has failed in the restart after the replacement of the load module (step C1 in FIG. 4). Next, the load modules in the save load module group 15 are replaced with the corresponding load modules in the software load module group 14 to return to the state before the replacement with the modified load modules (step C2). Finally, the application software or the OS to be monitored is restarted (step C3).
In this way, by monitoring the startup at the restart after replacing the modified load module and automatically recovering to the state before replacing with the modified load module when failure is detected, the man-hours of the recovery work can be reduced .
[0016]
FIG. 5 is a block diagram showing another embodiment of the present invention. Referring to FIG. 5, the recovery device after the replacement of the modified load module according to the present invention includes a boot processing unit 200 for monitoring the application software or OS to be monitored, a boot monitoring unit 231 for monitoring the boot of the monitored software, It includes a storage unit 121 and standby time storage units # 1 to #n (131 to 13n). In the activation processing unit 200, the activation monitoring unit 231 is allocated to the data processing device 2 illustrated in FIG. 1, and the time storage unit 121 and the standby time storage units 131 to 13n are allocated to the storage device 1 illustrated in FIG.
[0017]
The activation processing unit 200 divides the activation processing into several processing units (activation processing STEP1 to activation processing STEPn), before and after each processing STEP, monitoring start time registration means # 1 to #n (211 to 21n), Monitoring end time registration means # 1 to #n (221 to 22n).
The time storage unit 121 stores the start processing start time before the processing of each of the start processings STEP1 to STEPn by the monitoring start time registration means # 1 to #n and the monitoring end time registration means # 1 to #n. Information indicating that the startup process has been completed after the processes of the startup processes STEP1 to STEPn is stored.
The standby time storage units # 1 to #n (131, 132 to 13n) store the time required for each of the activation processes STEP1 to STEPn.
[0018]
Each of the processing means described above operates roughly as follows.
When the start processing of the application software or OS to be monitored starts, before the start processing STEPn in the start processing unit 200 starts, the monitoring start time registration unit #n (21n) stores the processing STEPn in the time storage unit 121. The processing start time is stored, and the processing of the activation monitoring unit 231 is started. After that, the activation processing unit 200 performs the processing of the activation processing STEPn, and when the processing is completed, the monitoring end time registration unit #n (22n) notifies the time storage unit 121 that the processing of the processing STEPn has been completed. Register the information to represent.
The startup monitoring unit 231 that has started the processing by the monitoring start time registration unit #n (21n) has elapsed the standby time stored in the standby time storage unit #n (13n) from the time stored in the time storage unit 121. Wait until you do. After the elapse of the standby time, the time storage unit 121 is referred to again to determine whether or not the processing of the startup processing STEPn has been completed. If the startup has failed, the load module is restored.
Since it is difficult to calculate the standby time in total with the system configuration or the startup of complicated software, a more appropriate standby time is monitored by monitoring in fine processing steps as in the embodiment shown in FIG. It becomes possible to monitor by time.
[0019]
【The invention's effect】
As described above, according to the present invention, since the startup is monitored at the restart after the replacement of the corrected load module, the number of steps of the startup confirmation work after the replacement with the corrected load module can be reduced. For example, when the replacement of the corrected load module is performed on multiple computers at the same time, or when the startup cannot be confirmed immediately due to business reasons, the startup of each computer is checked one by one at the next startup of the software to be monitored. There is no necessity, and the determination can be made by referring to the result automatically output by the activation monitoring unit 23 or the evacuation load module restoration unit 24.
In addition, startup monitoring is performed, and when a failure is detected, the system automatically recovers to the state before replacement with the modified load module. And the burden on the user or maintenance person is greatly reduced. Furthermore, by managing the time monitoring of the startup processing in smaller processing step units, monitoring can be performed with a more appropriate standby time.
