JP2669042B2 - Automatic volume incorporation processing method in business programs - Google Patents

Description

The present invention relates to an automatic volume embedding processing method in a business program, and more particularly to a business program of a computer system in which an input / output medium is used and an operator performs a medium loading operation therefor. The automatic volume incorporation processing method in.

(Prior Art) Conventionally, in this type of volume incorporation processing, as shown in FIG. 2, the operator inputs a command of medium information and device information after the medium loading (21) (22) and notifies the business program. This allows the loaded program to be made available through the business program through acquisition of media and device information (23), allocation of input / output devices and media (24), file opening (25), and file access (26). Was there.

(Problems to be Solved by the Invention) Since the above-described conventional volume incorporation process is used in the business program after the medium is loaded, it is necessary to notify the business program of the medium information and the device information by inputting a command by an operator. However, there is a drawback that a system aiming at automated driving involves a lot of operator intervention.

(Means for Solving the Problems) An automatic volume embedding processing method in a business program according to the present invention is an automatic volume embedding processing method in a business program of a computer system that performs an automatic operation. Means for outputting the medium information and device information of the specified medium to the console as a message, means for notifying the business program of the message output by the OS to the console, and medium information and device information in the business program. And a means for setting the loaded medium to the usable state, and only when the medium is loaded, the medium loaded with the business program is set to the usable state.

(Example) Next, the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing one embodiment of an automatic volume embedding processing method according to the present invention.

Hereinafter, a magnetic tape will be described as an example of the input / output medium.

First, the business program requests the OS to notify the contents of the message output to the console at the start of the business, and stores this (1, 2). Next, when the magnetic tape medium is loaded into the magnetic tape device (3), the OS knows that the medium has been loaded from the loading notification (4) from the device, reads the label of the loaded medium, and acquires the medium information ( 5) Output the medium information and the device information indicating the name of the loaded device to the console (6).

Since the business program has already requested to notify the contents of the message output to the operator console, the medium information and the device information are notified to the business program (7). The business program selects a medium information message and a message representing the device information from the notified device console output messages (8), and uses this information to assign the input / output device and medium (9) and open the file (10). ),
Allows access to files on loading media (1
1).

(Effects of the Invention) As described above, according to the present invention, when a medium is loaded, the OS notifies the business program of the medium information and the device information so that the operator notifies the medium information and the device information. Since there is no need for command input work, there is an effect that operator intervention can be reduced in a system aiming at automated operation, and errors caused by the operator can be reduced.

Claims (1)

(57) [Claims] In an automatic volume embedding processing method in a business program of a computer system for performing an automatic operation, an OS automatically recognizes a loaded medium and outputs medium information and device information of the loaded medium to a console as messages. Means, a means for notifying the business program of the message output by the OS to the console, and means for enabling a medium loaded in the business program based on medium information and device information. An automatic volume embedding processing method in a business program, characterized in that the medium loaded with the business program is set to a usable state only when the medium is loaded.
