Abstract

PURPOSE:To inform a user of the existence of a zombie process by previously executing a necessary process, judging whether the process exists or not and displaying the zombie process in a panel when it exists. CONSTITUTION:When the user executes log-in, a system is shifted to a log-in process, the process of the processing is called and whether the zombie process exists or not is recognized. When the zombie process exists, the panel displaying the existence of the zombie process is outputted. Here, the unnecessary zombie process is eliminated and therefore the system comes to a regulay available state.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing system equipped with a mechanism for performing predetermined information processing upon login to a workstation or the like.

0002

2. Description of the Related Art Conventionally, when a user logs in after starting up an information processing device such as a workstation, information provided to the user before the user uses the device is as follows:
This includes email information such as "You have mail," date, and time. Further, particularly in UNIX, information that can be known, changed, and maintained about the user's environment includes the remaining disk space, the number of file blocks, terminal attributes, and process status. The status of a process includes generation, update, change, disappearance, and termination of the process.

[0003] There is a parent-child relationship in which the process that issued the generation command is the parent and the parent process is the child. There is a zombie process that is not recognized by the system and is waiting to die, leaving only execution information. Accumulation of these zombie processes could cause problems.

0004

[Problems to be Solved by the Invention] However, in the conventional example described above, most of the information can only be obtained by inputting specific commands, and whether or not a zombie process exists can be determined in advance by the user without inputting any commands. could not know.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide an information processing system configured to notify a user of the existence of a zombie process through a panel display or the like.

[0006]

[Means for solving the problem] In an information processing system that performs necessary processing in advance at startup or login, when a parent process exists, the existence of a zombie process whose termination is not recognized by the parent process is detected. The apparatus is equipped with a determining means for determining the existence of the zombie process, and a notifying means for notifying the user when the existence of the zombie process is determined.

[0007]

[Operation] According to the present invention, when performing initial settings, necessary processing is executed in advance to determine whether or not a zombie process exists, and if a zombie process exists, a panel indicating the existence of a zombie process is displayed. By doing this, you can notify the user of its existence.

[0008]

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

FIG. 1 is a block diagram showing an information processing system according to an embodiment of the present invention. In the figure, 1 is an information processing system, 2 is a bus that sends and receives information within the information processing system, 3 is a CPU, and 4 is a RAM or ROM.
5 is an internal memory such as a magnetic disk or hard disk, 6 is a line interface connected to 10 such as Ethernet, 7 is an input device such as a keyboard or mouse, 8 is an output device such as a printer, 9 is 4 It is a display device like a bitmap display with gray scale gradation.

FIG. 2 is a flowchart showing the processing procedure of this embodiment. When a user logs in, the system passes to the login process, and this process is called (this may be included in a login profile prepared with the name .login). At this time,
Check whether a zombie process exists (step 1).

[0011] If a zombie process exists (step 2
), a panel indicating "zombie process exists" as shown in FIG. 3 is displayed (step 3). Here, “PROCES
SMONITER OPEN? ”, “OK”
Clicking on (or entering) (step 4) opens a window that provides process information, as shown in FIG. Here, the zombie process is deleted by checking the process contents and clicking or inputting "KILL" for the unnecessary zombie process (step 5). Further, by clicking or entering CANCEL, the normal usable state is achieved.

Next, other embodiments will be explained.

[0013] In the above-mentioned embodiment, the determination is made at the time of user login, but it is also possible to make the same determination at the time of starting up the machine, or at certain times (10 o'clock, 12 o'clock, 14 o'clock, etc.). It is also possible to set the system to check the process and perform this process.

[0014]

As explained above, according to the present invention, when performing initial settings, necessary processing is executed in advance to determine whether a zombie process exists, and if a zombie process exists, a panel indicating the zombie process is provided. By displaying this, it is possible to inform the user of the existence of zombie processes and eliminate problems caused by the accumulation of zombie processes waiting to disappear.
