Abstract

PROBLEM TO BE SOLVED: To mitigate the burden of an operator by enabling the operator to easily and surely select the selecting application to be ended. SOLUTION: A function judging whether necessary memory capacity remains in a main memory and calculating a memory using quantity is provided for OS(operating system). Otherwise, 'memory shortage monitoring application' with such a function is prepared to start the application just after the start of the system. At the time of trying the start of a new application program in a state where plural application programs are started, OS or the application judges whether the necessary memory capacity of the new application program exceeds a residual memory capacity. When the memory capacity is short, the fact is displayed and the memory using situation of the already started application is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a display for displaying a memory shortage in an information processing apparatus, and more particularly to a method and a display for displaying a memory shortage in an information processing apparatus having an operation system capable of starting a plurality of application programs. .

[0002]

2. Description of the Related Art An information processing apparatus provided with an operation system (OS) capable of starting a plurality of application programs (applications), when an operator attempts to start a new application while several applications are running, If the memory capacity required by the newly attempted application exceeds the total storage capacity of the main memory (memory), the OS notifies the operator of the memory shortage, and the operator receiving the notification notifies the operator of the memory shortage. In order to secure the memory capacity required by the newly started application, it is necessary to terminate some of the already started applications.

In a conventional information processing apparatus, when a memory shortage occurs, an operator cannot immediately know the use status of each memory of an already activated application, and the operator ends the operation based on experience and intuition. You have selected an application.

[0004] Further, even if an attempt is made to display the memory usage using an application for displaying the memory usage on a display device, the application cannot be started in such a case.

[0005]

As described above, an information processing apparatus having an operation system (OS) capable of starting a plurality of application programs (applications) requires an operator to start a new application while some applications are running. If an attempt is made to start a new application and the memory capacity required by the newly started application exceeds the total storage capacity of the main memory (memory), the OS notifies the operator of insufficient memory. Then, the operator who has received the notification needs to terminate some of the already started applications in order to secure the memory capacity required by the newly started application.

In the conventional information processing apparatus, when a memory shortage occurs, the operator cannot immediately know the use status of each memory of the already started application, so the operator terminates the operation based on experience and intuition. An application must be selected, which imposes a heavy burden on the operator, and has a disadvantage that the user may have to reselect the application because the selected application is inappropriate.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the conventional information processing apparatus. Is displayed on a display device, thereby easily and reliably selecting an application to be terminated and providing a memory shortage display method and a memory shortage display device capable of reducing the burden on an operator.

[0008]

According to a first memory shortage display method of the present invention, it is determined whether or not a required memory capacity remains in a main memory in an operation system capable of starting a plurality of application programs. A function for calculating the usage amount of the main memory of the application program to be started is possessed, and when an attempt is made to start a new application program in a state where a plurality of application programs are started, the new operation program is executed by the operation system. Determine whether the required memory capacity of the application program exceeds the remaining capacity of the main memory, and when the remaining capacity is exceeded, calculate the used amount of the main memory of the already started application program and display the result. Including display on the device That.

A second memory shortage display method according to the present invention has a function of determining whether or not a required memory capacity remains in a main memory and calculating a used amount of the main memory of an already started application program. Prepare an `` insufficient memory monitoring application '' having the following, start the `` insufficient memory monitoring application '' immediately after system startup, and try to start a new application program while a plurality of application programs are running. The "memory shortage monitoring application"
By determining whether the required memory capacity of the new application program exceeds the remaining capacity of the main memory, and when the remaining capacity is exceeded, calculating the usage amount of the main memory of the already started application program This includes displaying the result on a display device.

[0010]

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

FIG. 1 is a flow chart showing the operation of the first embodiment of the present invention, and FIG. 2 is a front view showing a display state on the display device at the time of a memory shortage display according to the embodiment of FIG.

When a new application is started (step 1), the OS determines whether or not the required memory capacity remains in the main memory in order to secure the necessary memory capacity for executing the application in the main memory. A decision is made (step 2). If the required memory capacity remains, nothing will be displayed in the shortage display section 21 because no memory shortage occurs (or "Memory is secured. Please execute the application" is displayed). , The operator executes the application (step 7). If the required memory capacity does not remain in the main memory, the shortage display section 21 indicates "Insufficient memory,
AP (4) application cannot be started "is displayed (step 3), and the memory capacity (memory usage) used by the already started application is subsequently calculated (step 4). This calculation of the memory usage includes not only the static memory usage at the time of starting each application but also the dynamic memory usage secured after startup, and is released when each application is terminated. Calculate to be the memory capacity. When the calculation of the memory usage is completed, the result is displayed on the memory usage display unit 22 (step 5). The operator looks at the display on the memory usage display unit 22 and terminates the application that is appropriate (step 6). When the termination of the application is completed, the OS returns to step 2 and determines again whether or not the required memory capacity in the main memory has been secured. At this time, the operations of Step 3 to Step 6 are repeated.

For example, as shown in FIG. 2, an application (1) (AP (1)) and an application (2) (A
In a state in which three applications of P (2)) and application (3) (AP (3)) are running, the operator newly creates an application (4) (AP (4)).
Is activated, if the memory capacity required by the newly attempted AP (4) exceeds the total storage capacity of the memory, the display device 31 displays the shortage display unit 21.
"AP (4) application cannot be started due to insufficient memory" is displayed, and the memory usage display unit 22 displays AP (1) 11, AP (2) 12 and AP (3) 13. Display each memory usage. In this case, the memory usage of the AP (1) 11 is 3,
280 KB, the memory usage of the AP (2) 12 is 5,321 KB, and the memory usage of the AP (3) 12 is 921 KB.

The memory capacity required by the AP (4) is 1,
When it is 250 KB, the operator looks at the display of the memory usage display unit 22 and checks the AP (1) 11 or the AP (1).
(2) Select 12 as the application to end.

FIG. 3 is a flowchart showing the operation of the second embodiment of the present invention.

The difference between this embodiment and the embodiment of FIG.
When the memory shortage occurs, the embodiment of FIG. 1 is configured so that the OS determines whether or not the required memory capacity remains in the main memory and calculates the memory usage. The present embodiment is configured to determine whether or not a required memory capacity remains in the main memory and calculate the memory usage by the “memory shortage monitoring application”.

That is, immediately after the system is started, the "memory shortage monitoring application" is started (step 10). The following operation is the same as the operation in steps 1 to 7 in FIG.

[0018]

As described above, the memory shortage display method of the present invention has a function of determining whether or not a necessary memory capacity remains in the main memory in the OS and calculating the memory usage. Prepare a `` memory shortage monitoring application '' that has a function to determine whether the required memory capacity remains in the main memory and calculate the amount of memory used. If the "memory shortage monitoring application" is started and a new application program is started in a state where a plurality of application programs are running, the OS or the "memory shortage monitoring application" requires a new application program. Determine whether the memory capacity exceeds the remaining memory capacity, and if the memory capacity is insufficient By displaying that fact and displaying the memory usage status of the already started application, it is possible for the operator to easily and reliably select the application to be terminated. There is an effect that the burden on the operator can be reduced.
