DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an error notification system, and more particularly, to a host computer system which manages a plurality of terminals, when a warning event from the system such as a power supply stop / restore and a forced termination start / end is recognized. The present invention relates to an error notification system that interrupts a keyboard input wait of each station and asynchronously notifies a system error.

[0002]

2. Description of the Related Art In a conventional error notification system,
For example, when a congestion state is detected, a queuing processing unit or a queuing notification unit is used as in the technique described in Japanese Patent Application Laid-Open No. 02-076447, and subsequent transmission processing is waited until the congestion state is recovered. However, when a fatal error of the system occurs while the job of each station is waiting for keyboard input, the above method cannot be used to display an error message in a timely manner.

[0003]

A problem with the prior art described above is that even if the system recognizes a warning event, the operator cannot know in a timely manner a fatal error or warning of the system. The reason is that even if an error message is to be displayed, the message cannot be displayed if the station is waiting for keyboard input.

It is an object of the present invention to provide an error notification system which can solve the above-mentioned disadvantages of the prior art and can timely display a warning message even when the station is waiting for a keyboard input. .

[0005]

A first error notification system according to the present invention includes a host system and a station, and has a function of displaying an error message on the screen of the station even when the station is waiting for keyboard input.

A second error notification system according to the present invention comprises:
(A) a host system including resource monitoring means for monitoring a system state and requesting a display of a message in response to an error, and a message storage area for storing the message; and (b) a program and a program waiting for keyboard input. The system includes a plurality of stations each including a screen control unit that issues a suspend instruction when waiting, and an error notification unit that is called by the screen control unit and displays an error message on a screen.

[0007]

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

FIG. 1 is a block diagram of an error notification system according to the present invention.

Referring to FIG. 1, the error notification system of the present invention comprises a host system 1 and stations 2 and 3 which are centrally managed by the host system 1. The host system 1 includes a resource monitoring unit 11 for monitoring the occurrence of a fatal error of the system such as a power supply stop / recovery or a forced termination start / termination, and a message storage area 12 for storing a message event. Further, the station 2 is called by the screen control means 21 for issuing a suspend instruction to the program waiting for keyboard input, the program 22 waiting for keyboard input, and the screen control means 21.
Error notification means 23 for displaying an error message on the screen
It is composed of Further, the station 3 includes a screen control unit 31 for issuing a suspend instruction to a program waiting for keyboard input, a program 32 waiting for keyboard input, and an error notification unit 33 called by the screen control unit 31 and displaying an error message on the screen. Consists of

Next, the operation of the error notification system shown in FIG. 1 will be described with reference to FIG.

FIG. 2 is a flowchart showing the operation of the error notification system of FIG. In FIG. 2, arrows indicated by solid lines indicate the flow of control.

First, the resource monitoring means 11 included in the host system 1 constantly monitors system failures such as power supply stop / recovery and forced termination start / end (step 0).

Here, when a power failure system failure occurs in the host system 1, the resource monitoring means 11 detects a warning event (step 1) and stores the error content in the message storage area 12 as bit information. Also, station resource information for displaying an error is recorded in the message storage area 12 (step 2).

The resource monitoring means 11 uses the station resource information in the message storage area 12 to
Issue a message display request to the screen control means 21 (step 4).

Upon receiving the message display request from the resource monitoring means 11, the screen control means 21 of the station 2 immediately notifies the completion of the reception of the message display request (step 5).

As a feature of this system, the resource monitoring means 1
The message display request issued by 1 is provided with a function of notifying the completion of reception as soon as the request is received by the screen control means of each station.

As a result, the resource monitoring means 11 can continuously execute a message display request to a plurality of stations via the station resource information recorded in the message storage area 12, and simultaneously execute error display processing at each station. Thus, a warning notification can be made to the operator of each station.

Next, the screen control means 21 of the station 2
Notifies the resource monitoring means 11 of the completion of the reception of the message display request, and checks the state of the program 22 using the resources of the station 2 (step 6).

If the program 22 is waiting for keyboard input, it issues an input cancel command and
The keyboard input waiting state of the program 22 is temporarily ended, and the resources of the station 2 are released (step 7).

When the resources of the station 2 are released, the screen control means 21 activates the error notification means 23 for displaying a warning message (step 8).

The error notifying means 23 saves the screen information (step 9), judges the contents of the error from the message storage area 12, and displays a warning message to the station 2 (step 10).

When the display of the warning message is completed, the error notification means 23 restores the screen information saved for business continuation (step 11), records the completion of the message display in the station resource information of the message storage area 12, and executes the processing. finish.

When the message display request to the station 2 is completed, the resource monitoring means 11 uses the station resource information in the message storage area 12 to
Issue a message display request to the screen control means 31 (step 12).

Upon receiving the message display request from the resource monitoring means 11, the screen control means 31 of the station 3 immediately notifies the completion of the reception of the message display request (step 13).

When the screen control unit 31 notifies the completion of the reception of the message display request to the resource monitoring unit 11, the screen control unit 31 checks the state of the program 32 using the resources of the station 3 (step 14).

If the program 32 is waiting for keyboard input, an input cancel command is issued and
The state of waiting for keyboard input of the program 32 is temporarily ended, and the resources of the station 3 are released (step 1).
5).

When the resources of the station 3 are released, the screen control means 31 activates the error notification means 33 for displaying a warning message (step 16).

The error notification means 33 saves the screen information (step 17), judges the content of the error from the message storage area 12, and displays a warning message to the station 3 (step 18).

When the warning message display is completed, the error notification means 33 restores the screen information saved for business continuation (step 19), records the completion of the message display in the station resource information of the message storage area 12, and executes the processing. finish.

In the above, the case where the number of stations is two has been described. However, it goes without saying that the operation is similarly performed in the case of three or more stations.

[0031]

As described above, the effect of the present invention is that a fatal error of the system can be known to the operator in a timely manner. The reason is that the screen control means of each station cancels the state of waiting for keyboard input, and the system warning message can be displayed asynchronously.
