2. Description of the Related Art FIG. 6 shows a conventional information processing apparatus. FIG. 6A shows the case where the application program performs the retry processing, and FIG. 6B shows the case where the device control device performs the retry processing.

Reference numeral 200 is an information processing device. 201 is an application program. A device controller 202 controls the input / output of the subordinate input / output device 203.

Reference numeral 203 denotes an input / output device, which is a printer,
Input / output devices such as displays and magnetic disk devices. 21 in the application program 201
Reference numeral 0 denotes a retry processing unit, which performs a retry process when a normal response is not returned from the input / output device 203.

Reference numeral 211 is a set value of the number of retries. Two
12 is a set value of the response time of the retry process. Figure 6
The operation of the configuration (a) will be described.

The application program 201 makes an input request or an output request to the device controller 202 with respect to the input / output device 203 (hereinafter, the input request and the output request are referred to as input / output requests).

The device control device 202 controls the input / output of the input / output device 203 by a control command. If an error occurs in the input / output device 203 and a normal response is not returned, the device control device 202 sends an error response to the application program 201 after the response time has elapsed.

The retry processing unit 210 instructs the device control apparatus 202 to perform retry processing. The device control device 202 performs a retry process.

After instructing the retry process, the application program 201 instructs the device control device 202 again to perform the retry process if a normal response is not returned within the response time 212. If a normal response is not obtained by the retry process, the retry process is repeated for the set number of times of retry (211). If the normal response is not obtained even after the retry processing is performed the specified number of times, the application program 201 ends in error.

FIG. 6B shows the configuration when the device control apparatus 202 performs a retry process. In Figure 6 (b),
Reference numeral 200 is an information processing device.

Reference numeral 201 is an application program. 202 is a device control device. Reference numeral 203 is an input / output device.

Reference numeral 210 is a retry processing unit. 211 is a set value of the number of retries. 212 is the response time of the retry process.

The operation of the configuration shown in FIG. 6B will be described. The application program 201 makes an input / output request to the device control device 202 with respect to the input / output device 203.

The device control device 202 controls the input / output of the input / output device 203 by a control command. If an error occurs in the I / O device 203 and a normal response is not returned, the retry processing unit 21 will return after the response time
0 performs a retry process for the input / output device 203.

If a normal response is not obtained by the retry processing, this retry processing is repeated for the set number of retries (211), and if a normal response is still not obtained, an error response is sent to the application program 201. To do. Application program 201
Ends in error.

[0016]

When the application program ends in error, it must be restarted.
It takes a long time before it can be used again. In particular, it becomes more difficult in the case of a large-scale system composed of multiple types of programs. Or,
Since data created up to that point will be lost when an error ends, it is necessary to prevent error end as much as possible in an application program with a large amount of created data, such as a graphics processing program.

On the other hand, the error termination rate can be reduced by increasing the number of retries or increasing the response time. However, increasing the number of retries and lengthening the response time increases the processing time of the application program and reduces the efficiency of the system.

It is considered that a system that requires a long time to restart because it is a large system or a system having a large amount of created data such as three-dimensional graphics should not end in error even if the retry processing time is long. On the other hand, some application programs should be easy to restart and should be able to process efficiently even if the error rate increases.

Therefore, it is desirable that the retry value can be freely set according to the application program. However, in the conventional application program, the retry processing is not performed for each error of the input / output device, and the retry value is also set in the device control unit. The retry value was not set by the user because it was set in advance during the product delivery process.

An object of the present invention is to provide an information processing apparatus in which a user can freely change the retry value for each input / output device and error content according to an application program.

[0021]

According to the present invention, there is provided a retry processing unit for performing a retry process when an error occurs in a controlled device under a device control unit, and a retry variable file for holding a retry value as a variable. For this reason, the variable value of the retry variable is set as the retry value, and the retry process is performed according to the variable value (retry value) in the retry variable file so that the user can easily change the retry value.

FIG. 1 shows the basic configuration of the present invention. In FIG. 1, reference numeral 1 is an information processing device.

Reference numeral 2 is an application program for information processing. A device control unit 3 controls input / output to a controlled device (eg, an input / output device) under its control in response to an input / output request of the application program 2.

Reference numeral 4 denotes a controlled device, which is an input / output device, a communication control device, or the like. An input device 5 is for inputting a retry variable designation, a variable value of the retry variable, and the like.

Reference numeral 11 is a retry variable file, which stores retry variables and retry variable values for retry values such as the number of retries and response time. For example, for an input / output device, a retry count variable A ₁ , a response time variable T ₁ and its variable values A ₁ = 5 (times), T ₁ = 10 (m
As shown in s), it holds a retry variable and a variable value (retry value).

Reference numeral 12 is a retry variable file creating section for setting variable values for retry variables. Reference numeral 12 'is a retry value setting unit, which uses the variable value of the retry variable file as a retry value.
Is written in the retry value holding unit 14.

In the device control section 3, 13 is a retry processing section for performing retry processing. 1
Reference numeral 4 denotes a retry value holding unit, which holds retry values such as the number of retries and response time.

[0028]

For example, the case of changing the retry value of the input / output device will be described. The retry variable A ₁ of the input / output device is designated by the input device 5, and the variable value (for example, 5 (times)) is input. The retry variable file creation unit 12 sets the retry variable A ₁ with a variable value = 5 in the retry variable file 11. Similarly, with the input device 5, the response time variable T ₁
Is specified and a variable value (for example, 10 (ms)) is input.
The retry variable file creation unit 12 sets a variable value = 10 for the retry variable A ₁ of the retry variable file 11. The retry value setting unit 12 ′ rewrites the contents of the retry value holding unit 14 of the device control unit 3 according to the contents of the created retry variable file 11.

When an input / output request is issued from the application program 2, the device control section 3 makes an input / output request to the controlled device 4. Then, if the controlled device 4 does not make a normal response, the retry processing unit 13 performs a retry process according to the retry value of the retry value holding unit 14.

According to the present invention, the number of times of retry processing and the response time can be freely set in consideration of the error content for each input / output device. Therefore, the user can freely set a retry value according to the application program, such as an application program that should not end in error even if the processing speed decreases a little, or an application program that should perform high-speed processing even if the number of error ends increases. Can be set, so a system with a high degree of freedom in environment settings can be created.
