Abstract

PURPOSE:To prevent a computer using time control system from being disabled from acquiring the usable time of the whole users due to the generation of abnormality in a computer system by controlling the usable time of each user by card storage. CONSTITUTION:A using time reading means 4 starts a card storage I/O device 2 to input data from a card storage and starts a computer system deciding means 9 to decide whether the usable time of the self-system is included in the input data or not. When the usable time is included, it is returned, and when not included, '0' is returned. A using time monitoring means 7 reads in the usable time, when the time is positive, informs a message indicating the allowance of execution and the usable time itself to a command processing means 6. The means 7 subtracts the processing time of a command executing means 8 from the usable time and starts a using time writing means 5. The means 5 starts the device 2 to update the usable time in the card storage. Consequently, trouble where the acquisition of the usable time of the whole users is disabled due to the abnormality of the computer system is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer usage time management method in a computer system.

[Conventional technology]

Conventionally, in computer systems, the available time allocated to all users is stored in a usage time management file within the computer system, and the usage time monitoring means inputs the usage time management file when opening a command input console. The computer was searched by user name, obtained the user's available usage time, and managed the computer usage time.

[Problem to be solved by the invention]

The conventional computer use time management method described above has the following problems because the available time is managed using a use time management file.

*If an error occurs in the computer system and the usage time management file is destroyed, it will become impossible to obtain usage time for all users.

Even if you make this operational mistake or intentionally open a command entry console with another user's name and execute the command, execution will still be allowed.

*Even if a single user uses multiple computer systems, the available time is managed individually for each computer system, so each computer system can only refer to the available time of its own system.

[Means to solve the problem]

The computer use time management method of the present invention uses, when a command, which is a business request unit, is input from the command input console, whether or not the command can be executed based on the available time allocated to the user. Determined by time monitoring means,
If it is executable, the command is executed by the command execution means, and then the usable time monitoring means updates the usable time, and if it is not executable, the command input console is notified that the command has been rejected. In a computer system having means, a card storage that records the usable time allocated to a user for each of a plurality of computer systems, a card storage input/output device for inputting and outputting the card storage, and the card. computer system determining means for determining whether or not data regarding the own computer system exists in the data input by the storage input/output device; and usage time reading for notifying the usage time monitoring means of the usable time of the own computer system. means and
and usage time writing means for outputting the available usage time updated by the usage time monitoring unit using the card storage input/output device, and the usage time of a plurality of computer systems of one user is collectively managed on the card storage. It is characterized by being made to do.

〔Example〕

Next, the present invention will be explained with reference to the V side.

FIG. 1 is a block diagram of a first embodiment of the present invention. This embodiment includes a command input console 1, a card storage input/output device 2, a computer system 3, usage time reading means 4, usage time writing means 5, command processing means 6, usage time monitoring means 7, command execution means 8, and a computer system. It is composed of system determining means 9.

FIG. 2 is a flowchart showing the operation of the command processing means 6 in FIG. 3 and 4 are flowcharts showing the operation of the use time monitoring means 7 in FIG. 1.

When a command is input from the command input console 1, the command processing means 6 reads the contents of the command in step 21, and starts the usage time monitoring means 7 in step 22. The usage time monitoring means 7 in the computer system 3 activates the usage time reading means 4 in step 31. Usage time reading means 4 is card storage input/output device 2
, input the data on the card memory, start the computer system determination means 9 to determine whether or not there is a usable time for the own system in the input data, and if so, return the usable time. If not, return O. The use time monitoring means 7 reads the available time in step 32, and determines in step 33 whether the available time is positive or zero. If it is positive, in step 34, the command processing means 6 is notified that execution is permitted and the usable time. If the answer is O, the command processing means 6 is notified in step 35 that the command cannot be executed.

The command processing means 6 determines in step 23 whether or not the command can be executed. If possible, the command execution means 8 is activated in step 24, the command execution means 8 waits for the available time for the processing of the command execution means 8 to be completed in step 26, and it is determined in step 27 whether the processing of the command execution means 8 has been completed or not. If it is not completed, the processing of the command execution means 8 is forcibly terminated in step 28. Thereafter, in step 29, the processing time of the command execution means 8 is notified to the usage time monitoring means 7.

The use time monitoring means 7 subtracts the processing time of the command execution means 8 from the available time in step 41, and activates the use time writing means 5 in step 42. The use time writing means 5 activates the card storage input/output device 2 and updates the usable time on the card memory. The command processing means 6 notifies the command input console 1 of the command execution result in step 2A.

On the other hand, if it is determined in step 23 that the command cannot be executed, then in step 25 the command input console 1 is notified that the command cannot be executed because the available time has been used up.

〔Effect of the invention〕

As explained above, the present invention achieves the following effects by managing the usable time for each user using card storage.

Since the computer system does not need to have a usage time management file, it is no longer possible to obtain the usage time of all users due to an abnormality in the computer system.

You can prevent commands from being executed under someone else's user name.

By collectively managing the usable time of multiple computer systems on one card storage, it becomes possible to refer to the usable time of multiple computer systems for one user from one computer system.

Claims (1)

[Claims] When a command, which is a business request unit, is input from the command input console, the usage time monitoring means determines whether or not the command can be executed based on the available usage time assigned to the user. If the command execution means executes the command, the usage time monitoring means updates the usable time, and if the command cannot be executed, the command processing means notifies the command input console that the command is rejected. In a computer system, a card memory records the usable time allocated to a user for each of a plurality of computer systems, a card memory input/output device performs input/output of this card memory, and this card memory input/output. computer system determining means for determining whether or not data regarding the own computer system exists in the data input by the device; and use time reading means for notifying the use time monitoring means of the usable time of the own computer system; and usage time writing means for outputting the available usage time updated by the usage time monitoring unit using the card storage input/output device, and the usage time of a plurality of computer systems of one user is collectively managed on the card storage.
