Abstract

PURPOSE:To control easily whether a large scale command unsuitable for the conversational processing can be executed or not by providing a means where the normal capacity of a command execution area, the names of permitted commands, and the special capacity of this area are registered. CONSTITUTION:A command analyzing part 1 not only selects a standard memory size or an extension memory size but also analyzes commands inputted from a conversational processing terminal 5 in accordance with the contents of a control flag which can be always changed from the external. Analyzed information is collated with a command execution control information in a storage part 6 by a collation processing part 2 to determine the capacity of the command execution area. A memory allocating control part 3 calculates the difference between a memory allocated at the conversational processing start time with the command execution area determined by the processing part 2 to reserve as area corresponding to this difference as a protected area 10 and executes commands left in a command execution area 1 by a command start part 4.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for controlling whether or not a command can be executed by registering the allowable amount of command execution area, and is particularly applicable to a computer center that operates interactive processing. The present invention relates to a command execution control method suitable for restricting the execution of large-scale commands.

[Background of the invention]

For example, as a command execution control method,
As shown in Publication No. 2475 and Japanese Unexamined Patent Publication No. 57-85121, the command name and the user who has the authority to use the command, or the command name and the permissible time period for inputting commands, are registered, and when the command is input, it is checked against the execution conditions mentioned above. It is said that there is something that controls whether or not it can be executed.

The former method does not have a concept of command input time periods, so large-scale commands may be input when the information processing system is under load, and there is no load adjustment function.

The latter is based on the idea of the permissible time period for command input,
Although there is a load adjustment function, it is necessary to register the allowable time period for command input for each command, so adding commands,
If you are busy changing commands, you need to register the commands.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a command execution control method to solve the above-mentioned drawbacks.

[Summary of the invention]

This system provides means for registering the normal allowable amount of the command execution area, the name of the authorized command and its special allowable amount, and the name of the command storage medium as command execution control information.

Furthermore, the memory allocated at the start of interactive processing is divided into a command execution area and a well logging area, and the latter area is secured prior to command execution. With K, it becomes possible to control whether or not general commands can be executed by utilizing the memory lag that occurs when general commands are executed in excess of the normal allowable amount.

On the other hand, commands that exceed the normal allowable amount are registered as authorized commands and the command execution area is enlarged, so that only authorized commands can be executed.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4.

FIG. 1 shows the configuration of this method, FIG. 2 shows the contents of command execution control information, FIG. 3 shows changes in memory, and FIG. 4 shows the processing flow of this method.

In this embodiment, the command execution control information has the contents shown in FIG. 2 and is registered in advance in the storage s6 in FIG. 1, the details of which are as follows. The standard memory size/expanded memory size can be used differently when the system load conditions differ, such as during the day and night, or between weekdays and holidays.

For authorized commands, the name of the command and the special allowance, which is the capacity of the required command execution area, are registered, and the command can only be executed when the name of the command storage medium is registered.

In Fig. 1, the first pro is a control flag (memory section 7) that can be changed from the outside at any time, and at the same time the standard memory size/extended memory size is selected. This part analyzes the command input from Step 5, and the information analyzed in Step 5 is compared with the command execution control information in the storage unit 6 in Step 2, and the allowable amount of command execution area is determined. decide. In step 3, the difference between the memory allocated at the start of interactive processing and the command execution area determined in block 2 is calculated and secured as the protected area 10. Command execution area 11K left after the above process, designated command storage medium 8
Alternatively, block 4 stores and executes the command read from block 9. FIG. 3 shows changes in the state of memory allocated at the start of interactive processing, and shows the relationship between the protected area and the normal allowable amount or special allowable amount.

Next, explanation will be given using FIG. 4. First, the control flag is determined, and either standard memorization or extended memorization is set as the capacity of the command execution area. Furthermore, the name of the command and the name of the command storage medium extracted by the command analysis process are compared with the registered contents shown in Figure 2 to determine whether or not they are authorized commands. The special allowance is reset as the capacity of the command execution area. below,
Calculates the capacity of the protected area, secures the protected area, reads the command, and starts the command.

〔Effect of the invention〕

As described above, according to the present invention, by controlling command execution using memory lag, it is possible to control whether or not to execute large-scale commands that are unsuitable for conversational processing, thereby increasing the speed of commands. be able to. Furthermore, since it is possible to change the control information and switch between standard memory size and extended memory size, it is possible to perform general-purpose operation depending on the busy state of the information processing system.

Claims (1)

[Claims] In an information processing system that analyzes and executes commands input from an interactive processing terminal, the memory area allocated at the start of interactive processing that can be used for command execution is designated as the command execution area. The area that cannot be used for this purpose is defined as a protected area, the command executed within the command execution area as a general command, and the command that is allowed to expand the command execution area as an authorized command, and the allowable amount of the executable area for general commands is defined. means for registering as command execution control information a normal allowable amount, a name of an authorized command, a special allowable amount, which is an allowable amount of an executable area, and a name of a command storage medium, which is a logical medium storing a command; By providing a means to calculate the memory capacity of the protected area by comparing the command executed with the command execution control information, and by pre-empting the protected area before executing the command and using the remaining memory area as the command execution area, the command execution can be improved. A command execution control method characterized by controlling availability.
