Description

The present invention relates to a business processing device in a terminal device such as a financial institution, and more particularly to a system control program and degenerate business (use) stored in a disk such as a plurality of floppy disks in advance. The present invention relates to an apparatus that loads a business (application) program including a frequently used business program and processes the business.

[Prior Art] Conventionally, in such a small terminal device, a floppy disk (FD) storing a system control program and a floppy disk storing a business program managed by the system control program are respectively stored in the floppy disk (FD). By allocating fixedly to the floppy disk drive (FDD) to be driven and reading them by the IPL (Initial Program Loader) via the corresponding FDD, the work including the degenerate work is processed.

[Problems to be Solved by the Invention] However, in the business processing device in the conventional terminal device, since each FD is fixedly allocated to the corresponding FDD, one FDD that drives one FD fails. However, the system control program and business program could not be read. Therefore, one terminal device in the store
In a place where there is only a stand, there is a problem that processing is performed manually until a maintenance person repairs the failure of the FDD, and the processing time per work becomes long.

The present invention solves the problems described above, and is capable of flexibly coping with a failure of an FDD and, if there is an FDD that can be used, at least a degenerate business using the FDD to continue the degenerate business. An object is to provide a processing device.

[Means for Solving the Problems] According to the present invention, a plurality of disk drive means for driving a plurality of disks, and a setting means for setting whether or not the disk drive means can be used for each disk drive means And assigning a logical number to the available disk drive means based on the setting result of the setting means, designating the logical number to be loaded by referring to the allocation result, and determining the contents of the disk from the disk drive means. And a disk control unit that is loaded to execute the job, the job processor reads the header of the disk according to the logical number, reads the type of the program stored in the disk, and controls the job by the program. An acquisition means for acquiring the program information, and a determination means for determining the number of disk drive means necessary for the business based on the acquired information. And a comparing means for comparing the number of disk drive means necessary for the determined work with the number of disk drive means set to be usable by the setting means, and the disk control means by the comparing means. It is configured to load the contents of the disk when the required number of disk drive means is larger than the available disk drive means, and to output an error message when the number is smaller.

It is preferable that one or more of the plurality of disks store in advance all or part of the degenerate business program managed by the system control program together with the system control program.

[Operation] The disk control unit (for example, a floppy disk control unit described later) allocates a logical number to the usable driving unit (for example, FDD) based on the setting result of the setting unit (for example, a setting unit described later), The contents of the disk are loaded from the logical means via the logical number to be loaded by referring to the allocation result (eg table). Here, by reading the program type stored in the disk and acquiring the business program information controlled by this program, it is possible to know whether some disk drive means is necessary for business processing. In this way, the number of disk drive means necessary for the work is compared with the number of disk drive means set to be usable by the setting means, and more drive means can be used than necessary disk drive means. If the job is executed, the error message indicating that the job cannot be executed is output.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 (a) is a block diagram of a terminal device to which the device of the present invention is applied. In the figure, 1 is C for controlling the entire apparatus

5, a floppy disk control unit for controlling 5, a display unit such as a CRT display for displaying the input image data on the display screen, and a display control for converting the input data to be displayed into image data and supplying it to the display unit 8a. Reference numeral 9 denotes an interface control unit for controlling an interface unit (not shown) for connecting to a host device or the like. CPU1 is RO
The M2, the RAM 3, the keyboard controller 46, the floppy disk control unit 7, the display control unit 8b, and the interface control unit 9 are connected by a bus 10.

FIG. 1B is a detailed configuration diagram of a portion related to drive control with the floppy disk such as the floppy disk control unit 7 described in FIG. 1A. As shown in FIG.
FDDs 50 to 5n are provided between the floppy disk control unit 7 and the FDDs 5 (50 to 5n) respectively driving the plurality of floppy disks (FDs) 6 (60 to 6n).
A setting unit 11 is provided for setting whether or not is available.
The setting unit 11 includes a number of AND gates 12 (120 to 12n) corresponding to the FDD 5, and a switch 13 (130 to 13n) for opening and closing the corresponding AND gate 12 depending on whether or not the FDD 5 is usable. In this embodiment, a ready signal indicating whether or not the floppy disk 6 is set in the FDD 5 is input to one terminal of the AND gate 12, and the output of the switch 13 is input to the other terminal. There is.

The floppy disk control unit 7 is realized by, for example, an IPL stored in the ROM 2, and has a logic number for controlling each FDD as described later. (Logical number) is the actual FDD
Assigned to the device numbers 50 to 5n of
It has an allocation processing function of storing it in the table a, and controls each FDD through this table.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG.
Description will be made with reference to the explanatory diagrams of the drawings.

Here, it is assumed that the most frequently used business (degenerate business) program is stored together with the system control program in one FD 60, and the other business programs are stored in FD 61 and subsequent FDs 60 to 6n.
It shall be set to 5n.

If all of the FDDs 50 to 5n are normal in advance, all the switches 130 to 13n are set to ON (output "H").

When the power of the terminal device is turned on, the floppy disk control unit 7 performs the following allocation processing after performing initialization such as clearing the RAM 3 (steps 20 and 21). Since all the switches 130 to 13n are set to ON, the ready signals from the FDDs 50 to 5n are output to the floppy disk controller 7 via the corresponding AND gates 120 to 12n. Therefore, the floppy disk controller 7
When the ready signal is input from each of the AND gates 120 to 12n, the FDD determines that the corresponding FDD can be used, and as shown in FIG. Is assigned to each FDD, and the result is stored in the RAM 3 as a table.

Next, the logical NO. The header (volume name, etc.) of FD is read sequentially from 0 (step 22). That is, the logical NO. When it is 0, by reading the header of the FD60 set in the FDD50, it is possible to know from the read information that the FD60 stores the system control program and the degenerate business program. Know the number, name and number of FDDs used in the business.

For example, when the number of tasks controlled by the system is “1” and the task program to be loaded is this degraded task, the system control program and the degraded task program are stored in one FD as described above. From that,
Since the number of FDDs used in this degenerate operation is "1", the logical NO. Since the header of the degenerate business program can be read via 0 and FDDs of 1 or more can be used, it is determined as “FD set combination OK”, and the system (control) program and the degenerate business program are loaded (step 23). , 24).

If the number of jobs controlled by the system is plural and the business program to be loaded is not a degenerate job, a logical N
O. From 1 onward, the header of the FD is read through the table, and it is determined whether the FDDs can be used more than the number of FDDs used in the job (step 23), and if they are available, the system control is performed. Load the program and the business program.

If it is determined in step 23 that the number of FDDs used in the work is less than the number, an error message is displayed on the display screen of the display unit 8a via the display control unit 8b (step 2).
5).

On the other hand, when some of the FDDs 5 have failed, the switch 13 corresponding to the failed FDD is set to OFF (output “L”). Therefore, when the terminal device is reset, the flowchart of FIG. 2 is executed in the same manner as above, and in the allocation process of step 21, the FDD to which the ready signal was input from the AND gate 12 (that is, the usable FDD ) To the logical NO. Assign. For example, when the FDD 50 fails, it is assigned as shown in FIG. 3 (b), and when the FDD 51 fails, as shown in FIG. 3 (c), the results are assigned as a table to the RAM 3
To store. Therefore, the floppy disk control unit 7 outputs the logical NO. Since the FDD 5 is controlled via the FDD, a business program that can be controlled within the range of the number of normal FDDs
It becomes possible to load and execute the business via the DD. In particular, in the case of the degenerate work, since the degenerate work program is stored in one FD 60 together with the system control program, it can be executed if one FDD is normal.

In the case of FIG. 3 (b) (when the FDD 50 is out of order),
Since the FD 60 for degenerate work has been set in the FDD 50 at the normal time, it is necessary to reset it in another normal FDD.

In the above-described embodiment, the system control program and all the degenerate business programs are stored in one FD. However, if the amount of the degenerate business programs is large, a part of them is stored and the remaining FDs are stored. By storing the data in a divided manner, the degenerate work may be executed with the minimum necessary FD.

Further, although the FDD for driving the FD has been described in the above embodiments, it is obvious that the present invention can also be applied to a terminal device equipped with a driving unit for driving a disk such as a magnetic disk similar to the FD.

[Effects of the Invention] As described in detail above, according to the present invention, the header of a disk is read according to a logical number, the type of the program stored in the disk is read, and business program information controlled by the program is acquired. Acquiring means, judging means for judging the number of disk driving means necessary for the business based on the acquired information, the number of disk driving means necessary for the judged business, and the number of disk driving means set to be usable by the setting means The disk control means loads the contents of the disk when the number of disk drive means required by the comparison means is larger than the number of available disk drive means, and when the number is small, Is configured to output an error message, it makes the best use of available disk drive means Can handle business. Further, since the number of usable disk drive means and the number of disk drive means necessary for business can be easily obtained, quickness in dealing with a failure is increased.

In particular, when the system control program and the degenerate work program can be stored in one disk, the degenerate work can be continued if one drive unit is normal.
