DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an error information collection test system, and more particularly to an error information collection test system used for a running test in which test diagnosis of an information processing apparatus is repeated for a long time and repeatedly.

[0002]

2. Description of the Related Art Conventionally, in a running test of an information processing apparatus, if a test diagnosis control program detects an error that causes a system down during the running test, the operator performs some action such as resetting the information processing apparatus. The test diagnosis has stopped at that time until the event occurs.

When the system goes down, the state of the CPU register and the state of the stack area at that time and the task (test diagnosis program) being executed are analyzed to analyze the cause of the error that led to the system down.
The operator manually collects information such as the status of the main storage unit, the status of the information processing device, and the like.

[0004]

In the running test of the conventional information processing apparatus described above, if an error that causes the system to go down during the running test is detected, the test diagnosis is performed at that time until the operator takes some action. Since the system will stop, especially in the case of running tests during nighttime when there is no manpower, if the system is shut down shortly after the test starts and the test diagnosis is stopped, it will be left as it is for a long time, until the test diagnosis is restarted. There is a problem that it takes time.

Further, since the operator manually collects information such as the state of the information processing apparatus when the system goes down, it is necessary to reset the information processing apparatus after the information collection and re-execute the test diagnosis. In addition, there is a problem that it takes time to restart the test diagnosis.

Therefore, an object of the present invention is to solve the above-mentioned problems and to automatically collect information such as the state of the information processing apparatus, and automatically reset the information processing apparatus after the information collection. It is an object of the present invention to provide an error information collection test system that can re-execute test diagnosis.

[0007]

An error information collection test system according to the present invention is an error information collection test system used for a running test in which test diagnosis of an information processing apparatus is repeated for a long time and repeatedly. A flag that indicates that the information processing apparatus has gone down, a holding unit that holds information that specifies a diagnostic program when the information processing apparatus goes down, and a storage unit that stores information identifying the diagnostic program when the information processing apparatus goes down. Software reset means for forcibly transferring control to the test diagnosis processing means; and error information from the information processing apparatus based on the contents of the flag after the forced control transfer processing by the software reset means. Determining means for determining whether or not the error information is collected; Storage means for storing collection range information set in advance, and when the determination unit determines that the error information should be collected, the storage unit stores the collection range information based on the collection range information of the storage unit. and error information collecting means for collecting the error information, a test resumption means to re-run the test diagnostics of the information processing apparatus based on the contents of the holding means after the collection of the error information collecting means and the error information by the information processing For testing and diagnosing equipment

When the test diagnosis of the processing device is re-executed, the test diagnosis of the storage means is performed.
The test diagnostic program to be executed next is
Means for extracting and re-executing a test diagnosis of the information processing apparatus
And

[0008]

In another error information collecting test system according to the present invention, in addition to the above configuration, the error information collecting means may collect the error information before the error information is collected and before re-executing a test diagnosis of the information processing apparatus. There is provided means for performing a hardware reset of the device.

[0010]

In the test diagnosis of the information processing apparatus, the fact that the system of the information processing apparatus has been shut down is specified in the information collection flag, and the program name of the test diagnosis program at that time is stored in the program name storage area.

Then, when the control is forcibly transferred from the test diagnosis program at the time of the system down to the test diagnosis control program and it is determined that error information should be collected from the information processing apparatus based on the contents of the information collection flag. An error collecting unit collects error information from inside the information processing device based on the information in the information collecting address table.

After collecting the error information, the hardware is reset, and then the test resuming unit re-executes the test diagnosis program of the information processing apparatus based on the program name stored in the program name storage area.

This makes it possible to automatically collect information for error analysis even when an error that causes a system down is detected in a running test of the information processing apparatus, particularly an unmanned test such as at night.

Thus, the hardware test of the information processing apparatus can be performed after the error information is collected, and the running test can be automatically restarted. Therefore, the test can be efficiently stopped without being stopped. Test, diagnosis, and evaluation are possible.

[0015]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In the figure, a test diagnosis control program 1
Indicates a test diagnosis processing unit 10 and a software reset unit 11
, An information collection determination unit 12, an information collection unit 13, an information collection address table 14, a test resumption unit 15, and a program name storage unit 16, which are connected to the information collection flag 2 and the program name storage area 3. Have been.

The test diagnosis processing unit 10 controls the entire system such as resource management of the information processing apparatus (not shown) and execution management of the test diagnosis program, and executes the test diagnosis program instructed by the operator. Run on resources,
A series of controls such as outputting the execution result to a console screen (not shown) are performed.

The software reset unit 11 detects the state of the CPU register, the state of the stack area, the state of the task (test diagnosis program) that has been executed,
The information processing apparatus is reset without destroying the state of the main storage unit, the state of the information processing apparatus, and the like.

That is, when an error that leads to a system failure such that the test diagnosis program falls into an infinite loop is detected, the software reset unit 11 temporarily stops the processing by the infinite loop and the like, and starts the test diagnosis processing unit from the infinite loop. Then, a process for forcibly returning control to 10 is performed.

The information collection flag 2 is referred to when a software reset or a cold reset (hardware reset) of the information processing apparatus is performed, and is used to determine whether to collect error information.

When the test diagnosis program is re-executed, the information processing apparatus must be initialized, and a cold reset of the information processing apparatus is executed. Here, since the cold reset means a reset equivalent to the power-on reset, the information collection flag 2 is secured in a resource such as a nonvolatile RAM or an external storage device which is not affected even if the cold reset is executed.

The information collection determining unit 12 refers to the information collection flag 2 and determines whether or not to collect error information. The information collection unit 13 refers to the information collection address table 14 when the information collection determination unit 12 determines that information collection is necessary, collects information of a required size from the address indicated by the information collection address table 14, and stores the information in a floppy disk. Etc. in an external storage device (not shown).

The information collection address table 14 holds information on the memory address and size of error information to be collected by the information collection unit 13 in advance.

The test resuming unit 15 performs a software reset by the software reset unit 11 after the test diagnosis processing unit 10 detects an error that causes the system to go down.
After the necessary error information is collected by the information collecting unit 13, the information processing apparatus is cold-reset. Thereafter, the test resuming unit 15 refers to the program name storage area 3 and re-executes the test diagnostic program that was being executed when the error that caused the system to go down or the next test diagnostic program.

The program name storage unit 16 stores the name of the test diagnosis program that was being executed when the test diagnosis processing unit 10 detected an error that caused the system to go down, in the program name storage area 3. The program name storage area 3 is an area where the program name storage unit 16 stores a test diagnosis program name.

FIG. 2 shows the information collection address table 1 of FIG.
4 is a diagram showing a configuration of FIG. FIG. 2 shows the test diagnosis program 1
In the information collection address table 14, a memory address and a size indicating how much information is required from the memory address are stored alternately.

That is, from the address “00000000” indicated by the memory address 100 to “2” indicated by the size 101
56 bytes of information, “320000” bytes of size 111 from address “00001000” indicated by memory address 110, and “0000200”
This means that information of "2548" bytes from address "0" and information of "168" bytes of size 1m1 from address "5002000" indicated by memory address 1m0 are sequentially collected.

Note that "fff" indicated by the memory address 1n0.
ffffff ”address specially in information collection address table 1
4, which indicates that the information collection address table 14 is over.

FIG. 3 is a flowchart showing the operation of one embodiment of the present invention. The processing operation of the running test of the information processing apparatus according to one embodiment of the present invention will be described with reference to FIGS.

When the initialization of the information processing apparatus is performed in the start-up operation (cold reset) of the information processing apparatus (step S1 in FIG. 3) (step S2 in FIG. 3), the control is transferred to the test diagnosis control program 1. When the control is passed, the test diagnosis control program 1 checks whether the information collection flag 2 is set (step S3 in FIG. 3).

Since the information collection flag 2 is not set in the normal start-up operation, the test diagnosis control program 1 enters the test diagnosis processing idle state (step S3 in FIG. 3).
4). Here, the test diagnosis processing idle state refers to a state in which the test diagnosis program is not executed for the resources of the information processing apparatus, and waits for an activation request from the operator.

When the test diagnosis control program 1 is in the test diagnosis processing idle state, when the operator inputs a request for starting the test diagnosis program for the resources of the information processing apparatus from an input device (not shown) such as a keyboard, the test diagnosis processing is started. Part 1
0 starts execution of the test diagnosis program (step S9 in FIG. 3).

When the test diagnosis program is normally executed, the test diagnosis program performs a test diagnosis on the resources of the information processing apparatus, and outputs the result to a console screen or the like (not shown) (step 3 in FIG. 3). S11), the test diagnosis program ends (step S12 in FIG. 3).

When the test diagnosis program ends, the test diagnosis processing section 10 enters the test diagnosis processing idle state in step S4 again. In the running test of the test diagnosis program, the above processing is repeatedly executed.

Next, when the test diagnosis program or the test diagnosis processing unit 10 detects an error during the running test,
It is determined whether or not the error is an error worthy of system down (step S10 in FIG. 3). If the error is not worth the system down, the error is output to a console screen or the like and displayed as an error (step S1 in FIG. 3).
1), the test diagnosis program ends (step S12 in FIG. 3).

On the other hand, if the error is a fatal error that should cause the system to go down, the test diagnosis processing unit 10 stores the program name of the test diagnosis program being executed when the error was detected by the program name storage unit 16. The information is stored in the name storage area 3 (step S16 in FIG. 3), and the information collection flag 2 is set (step S17 in FIG. 3).

The test / diagnosis processing section 10 sets information indicating that software reset is to be executed in the information collection flag 2 (step S18 in FIG. 3), and executes software reset by the software reset section 11 (step S19 in FIG. 3). ).

At this time, if the test diagnosis program has fallen into an infinite loop due to the occurrence of an error, the software reset unit 11 disconnects the control from the infinite loop and forcibly returns to the test diagnosis processing unit 10. Therefore, CP
The state of the U register, the state of the stack area, the state of the task (test / diagnosis program) being executed, the state of the main storage unit, the state of the information processing apparatus, and the like are not destroyed and are left as they are.

The processing of the information processing apparatus is stopped without destroying the contents of the main storage unit by the software reset, and the control is transferred to the test diagnosis control program 1. Therefore, the test diagnosis processing unit 10 Flag 2
It is checked whether or not is set (step S3 in FIG. 3).

In this case, since an error that would cause the system to go down is detected and the information collection flag 2 is set, the information collection determination unit 12 determines whether the software reset is performed based on the contents of the information collection flag 2. It is determined whether or not it is (step S5 in FIG. 3).

When the information indicating that the software reset is to be executed is set in the information collection flag 2, the information collection determination unit 12 determines that there is a software reset. Information is collected from the information processing device based on the contents of the address table 14 (step S13 in FIG. 3).

That is, the information collection unit 13 refers to the contents of the information collection address table 14 and analyzes the cause of the error that has led to the system down, the CPU register state, the stack area state, and the execution at that time. Task (test diagnosis program) status, main memory status,
Information such as the state of the information processing apparatus is collected, and the collected information is stored in an external storage device such as a floppy disk.

When the collection and storage of information and the like in the information processing apparatus by the information collection unit 13 is completed, the test diagnosis processing unit 10
Performs a cold reset of the information processing apparatus (step S14 in FIG. 3), and deletes information indicating that a software reset is to be executed from the information collection flag 12 (step S15 in FIG. 3). Here, information indicating that error information has been collected is left in the information collection flag 2.

When the cold reset is executed, the same reset processing as the power-on (POW ON) reset is executed to initialize the information processing apparatus, and the control is passed to the test diagnosis control program 1 (step S1 in FIG. 3). , S
2) The information collection flag 2 is checked by the information collection determination unit 12 (step S3 in FIG. 3).

In this case, since the information collection flag 2 is set, the information collection determination unit 12 determines whether or not software reset has been performed based on the contents of the information collection flag 2 (step S5 in FIG. 3). .

The information collection determination unit 12 sets information indicating that error information has been collected in the information collection flag 2,
Since the information indicating that the software reset is to be executed is not set, it is determined that there is no software reset. Therefore, the test diagnosis processing unit 10 reads out the contents of the program name storage area 3 by the test resuming unit 15 and executes it when the system is down. The program name of the test diagnosis program used is obtained (step S6 in FIG. 3).

When the test resuming unit 15 obtains the program name of the test diagnosis program, the test diagnosis processing unit 10 turns off the information collection flag 2 (does not have any meaning) (step S7 in FIG. 3) and saves the program name. The test diagnosis program is started by the test resuming unit 15 based on the program name of the test diagnosis program read from the area 3 (step S in FIG. 3).
8), the execution of the test diagnosis program is resumed (Step S9 in FIG. 3).

When the test diagnosis program ends, the test diagnosis processing section 10 enters the test diagnosis processing idle state in step S4 again. In the running test of the test diagnosis program, the above processing is repeatedly executed.

In the above processing, the same test diagnosis program is restarted. However, a test diagnosis program sequence for performing a test diagnosis of the information processing apparatus is stored in a storage device (not shown). When the test diagnostic program of the information processing device is re-executed, the test diagnostic program to be executed next may be extracted from the test diagnostic program sequence of the storage device and executed.

As described above, in the test diagnosis of the information processing apparatus, the fact that the system of the information processing apparatus has been shut down is clearly indicated in the information collection flag 2, and the program name of the test diagnosis program at that time is stored in the program name storage area 3. After that, when it is determined that error information should be collected from the information processing apparatus based on the contents of the information collection flag 2 after forcibly shifting the control from the test diagnosis program at the time of the system down to the test diagnosis control program 1 The information collection unit 13 collects error information from within the information processing apparatus based on the information in the information collection address table 14, and after collecting the error information, performs a hardware reset and uses the program name stored in the program name storage area 3. Test restart section 1
By re-executing the test diagnosis program of the information processing device in step 5, information collection for error analysis is automatically performed even when an error that causes a system down in a running test of the information processing device, particularly an unmanned test at night or the like is detected. can do.

Thus, the hardware test of the information processing apparatus can be performed after the error information is collected, and the running test can be automatically restarted. Therefore, the test can be efficiently stopped without being stopped. Test, diagnosis, and evaluation are possible.

[0052]

As described above, according to the present invention, in the test / diagnosis of the information processing apparatus, the fact that the system of the information processing apparatus has been shut down is specified in the flag, and the information for specifying the diagnosis program at that time is held. After that, after the system is down, the control is forcibly shifted from the diagnostic program to the test diagnosis processing means, and when it is determined that error information should be collected from within the information processing apparatus based on the content of the flag, the preset value is set in advance. Error information is collected from within the information processing apparatus based on the information on the collection range of the error information, and after the error information is collected, the test diagnosis of the information processing apparatus is re-executed based on the information specifying the diagnostic program held when the system is down. As a result, information such as the state of the information processing apparatus can be automatically collected, and the information processing apparatus is automatically collected after the information is collected. There is an effect that it is possible to re-run the test diagnostics by de hardware reset.
