JPS60198644A - Local error processing system of on-line system - Google Patents

Abstract

PURPOSE:To omit the processes to be performed at the host side such as a command restarting action, page matching action, etc., by processing a local error produced at a work station at the work station itself. CONSTITUTION:A work station 12 contains a microprocessor and a buffer 13 which stores data given from a host device 11. A local error detected by a control part after unfolding the error on an image memory 14. The detected error is displayed and an operator starts operations. When the operator resolves the error factor and then pushes a start key, a printing part 17 prints again the information on the memory 14 of the same page. Then the error is displayed again in case the error factor remains yet even after the start key is pushed. Thus the operator performs operations again.

Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to an online system, and in particular, when a local error is detected at a workstation, the workstation processes the error and then reports it to the host computer. Regarding the method.

(2) Conventional examples and problems Conventionally, when a local error is detected in a workstation (terminal) in an online system, the abnormal termination is reported to the host computer and the command ends with an error. There was a drawback that it took too much time to process errors because local errors had to be removed and processes had to be performed, such as restarting the system using commands.

(3) Purpose of the Invention In view of the above drawbacks, the present invention provides a method for quickly recovering the online system by processing errors within the workstation without reporting abnormalities to the host computer. The purpose is to provide.

(4) Structure of the Invention The object is to provide a means for processing local errors occurring in a workstation within an online system consisting of a plurality of workstations and a host computer, and to guarantee data from the host. This is achieved by a local error handling method in an online system characterized by providing a buffer at the workstation.

(5) Examples of the invention The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a system configuration diagram showing an embodiment of the present invention.

In the figure, 11 is a host computer, 12 is a workstation (VIP), 13 is a sofa, 14 is an image memory, 15 is a control unit, and 16 is a diagram showing the processing flow of the printer. The present invention is a method that can be realized by having the waffle 13.

First, the print processing of the workstation 12 will be described. When a command is issued from the host computer 11, it is stored once in the buffer 13 and the data is transferred to the image memory 1.
After the image is developed on the image forming apparatus 4, the printing section 17 performs printing under the control of the printer control section 16.

To detect a local error (out of paper, stacker full, pink jam, etc.), the control unit 15 checks whether there is an error after it is expanded on the image memory 14. If an error is detected, an error is displayed or an error is printed. and waits for operator intervention. Next, when the operator cancels the error cause and presses the 3tart key (not shown), the printing unit 17 can print again using the information in the image memory 14 of the same page.

If the cause of the error still remains after pressing the 5trat key, the control unit 1 will display the error again or print the error.
5 and enters the operator intervention state.

When the printing process has ended normally as described above, the normal end is reported to the host computer 11.

(6) As explained in detail of the invention, by processing local errors that occur on the workstation without reporting them to the host computer, processing power5 for command restarts, page matching, etc. (on the host side) is eliminated. , processing efficiency can be improved.
