A maintenance terminal equipment 1 is provided with a communication control part 11 for controlling a data communication to a host computer 3, an error message display part 21 for displaying and printing the error message, a printer 32, a keyboard display 31 for inputting correction data of a correction of a program and a change of the environment, and an input/output part 22 for controlling this display.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for operating an online system, and more particularly to a remote maintenance system for the online system.

[0002]

2. Description of the Related Art Conventionally, in the maintenance of an online system, an operator (user) of the online system must detect a fault in the online system, analyze the content of the fault together with a maintenance engineer (SE), and correct it. If it was found, the maintenance personnel went to the installation location (on-site) of the host computer to modify the program.

Also, when a change in the online system environment occurs (addition of online terminals, etc.), a maintenance worker also goes to the site to change the environment of the host computer.

[0004]

In the above-mentioned conventional method, the operator of the online system performs the detection of the failure and the analysis of the content of the failure (for example, the work of collecting the data at the time of the failure) or in accordance with the instruction of the maintenance staff. Will be done because
There is a problem that it takes time from the occurrence of a failure to the detection of the failure, and from the detection of the failure to the end of the analysis of the details of the failure.

Further, even in the work of modifying the program and the work of changing the environment of the online system, it is necessary to always go to the place where the host computer is installed to carry out the work.

DISCLOSURE OF THE INVENTION The present invention is a fault detection unit for inputting driving information to detect a fault in an online system, and an error message for notifying the abnormality of the online system by the inputted driving information. A determination unit for determining whether or not the input operation status is an error message, an error message editing unit for editing the operation message and adding a predetermined identification code, and an error message for outputting the edited error message. A plurality of host computers having an output unit and a first communication control unit that controls data communication with other terminal devices; and a second communication control unit that controls data communication with the plurality of host computers. , An error message display section for displaying or printing out the error message, a printer, and the plurality of host computers. A terminal device for maintenance having a keyboard display for inputting correction data for modifying a program and changing the environment for a computer, and an input / output unit for controlling the keyboard display; the plurality of host computers and the maintenance device A line unit for transmitting the error message and the correction data to and from the terminal device is provided.

[0007]

Next, this embodiment will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, 1 is a maintenance terminal, 2 is a line section, and 3 is a host computer.

FIG. 2 is an overall configuration diagram of this embodiment.
1 to 43 are host computers each having an independent online system, 44 is a line section, and 45 is a maintenance terminal.

Referring to FIG. 1, the host computer 3 is
System operation information (messages from the operating system and application programs) is output to the message log file 33 as needed. The failure sensing unit 24 takes in these various messages and judges them by the judgment unit 25.
Pass to. The determination unit 25 determines whether or not the input message is a message for notifying the abnormality of the online system, and if the message is for notifying the abnormality of the system, the message is passed to the error message editing unit 26. At this time, when the judgment unit 25 judges the message, the level of the failure message notified to the maintenance terminal 1 can be changed by setting the message level in advance.

The error message editing unit 26 adds the identification name of the host computer 3 to the message passed from the judging unit 25, and passes the edited message to the error message output unit 27. The error message output unit 27 outputs the message to the line unit 2 via the communication control unit 12.

On the side of the maintenance terminal 1, the message sent from the line section 2 is received by the error message display section 21 via the communication control section 11. The error message display unit 21 outputs a message on the keyboard display 31 and the printer 32 as needed.

On the other hand, a program modification or environment modification for the host computer 3 having an online system is
A maintenance person uses a keyboard display 31 in the maintenance terminal 1.
It is performed by operating. At this time, the input / output unit 22 for controlling the keyboard display 31, the communication control unit 11 on the side of the maintenance terminal 1, the line unit 2, the communication control unit 12 on the host computer side, and the text editor function in the host computer 3 are used. Note that the above-described program repair work and environment change can be performed from the maintenance terminal device 45 shown in FIG. 2 to any of the host computers 41 to 43 via the line unit 44.

[0014]

As described above, according to the present invention, the failure information of the online system can be automatically transmitted to the maintenance staff by connecting the host computer constituting the online system and the maintenance terminal with a line. Since it is possible and corrective action and change action can be performed on a remote host computer, there is an effect that prompt failure response is possible.
