Abstract

PURPOSE:To control the correction data with high efficiency by dividing and editing the correction data for each level in a collective correction mode or each item in an emergency correction mode. CONSTITUTION:A correction data dividing/editing processing part 15 of a host processor 10 reads a correction control information MCS file 13 and a relative file 14 out of a correction data offering magnetic tape 12 storing the correction data and then stores the correction data into a correction data storing file 16 after arranging them for each level in a collective correction mode or each item in an emergency correction mode based on the contents of the file 13. A correction data transmission processing part 18 of the processor 10 refers to a correction level control file 17 to extract the necessary data out of the file 16 and stores these data in a correction data storing file 21 via a correction data reception processing part 20 of a sub-host processor 11. A correction data editing/restoring processing part 22 of the processor 11 restores an MCS file 23 and a relative file 24 out of the file 21.

Description

[Detailed Description of the Invention] [Summary] When performing remote maintenance by transmitting modified data stored in a modified data providing storage medium such as a magnetic tape, managing the modified data becomes complicated and unnecessary data is sent. In order to solve this problem, the modified data is divided and edited into basic units, only the necessary modified data is sent, and the receiving side restores it to its original format and applies it.

Easier management and efficient transmission of revised data! and can be applied.

[Industrial application field]

The present invention provides a remote maintenance control method, in particular, a host processing device that manages remote maintenance sends correction data based on a correction data provision storage medium prepared in advance to a sub-host processing device that is the target of remote maintenance, thereby efficiently making corrections. This relates to a remote maintenance control method that allows data to be applied.

[Conventional technology]

If there is an error in the program provided to the user, the correction data will be provided to a storage medium such as magnetic tape.

Store and distribute modified data. Usually, for a certain period of time,
It accumulates or aggregates various correction data up to that point and distributes it as batch correction data.

If there is important and urgent data to be corrected.

Apart from bulk correction, a correction data provision storage medium is created as emergency correction data and maintenance is performed immediately.

It is considered convenient to transmit such correction data through a telephone line or the like, since remote maintenance can be performed. For example, as a method for remote maintenance,
No. 0-115810 "Remote maintenance method" has been proposed. However, this method does not directly handle correction data providing storage media such as magnetic tape.

[Problem that the invention seeks to solve]

For example, if all computer systems can be targeted for remote maintenance at the same time, maintenance management can be performed relatively without problems. but.

Due to the number of computers installed, time constraints, and compatibility with existing patch application programs, one-step remote maintenance is necessary, and direct individual maintenance using conventional correction data provision storage media is not possible. and remote maintenance must coexist.

In this case, to avoid double management of modified data.

It is considered appropriate to perform remote maintenance based on a correction data provision storage medium created for on-site maintenance.

FIG. 6 is a diagram explaining the problem of the present invention.

The correction data providing magnetic tape 12 is at the beginning.

It has a modification control information (MC8) file 13 in which modification control information is stored. Further, in accordance with the modification control information, the relative files 14 to be replaced with the load module to be modified are stored in order. These corrected data,
When sending the data to the sub-host processing device, it is necessary to copy it to the direct access device (DASD) 30 such as a 2M1 disk device and then send it, but this poses the following problem.

The MCS file 13 stores modification control information of various modification levels, and if this file is sent as is, all relative files 14 associated with it must be sent, resulting in a large amount of data to be sent.

Moreover, since some of the relative files 14 may be the same (for example, alwcl), management becomes complicated due to duplication of file names. especially,
Provide multiple correction data from magnetic tape 12 to DASD 30
When storing and managing the files copied above, it is difficult to separate unnecessary files from necessary files.

Management is complicated.

An object of the present invention is to solve the above-mentioned problems, to efficiently manage modified data, and to enable only the modified data to be applied to a sub-host processing device to be transmitted.

[Means for solving problems]

The modified data division/edit processing unit 15 extracts the modified data from the modified data providing magnetic tape 12 on which the modified data is stored.

Read MCS file 13 and relative file 14, and
Depending on the contents of CS file 13, each rubel in bulk correction or each item in emergency correction is the basic unit.
It performs a process of compiling the corrected data and storing the edited corrected data in the fC original data storage file 16.

The modified data transmission processing unit 18 extracts the basic unit of necessary modified data from the modified data storage file 16 by referring to the modified level management file 17, and transmits it to each sub-host processing device 11. It is something.

The modified data reception processing unit 20 receives and receives modified data from the host processing device 10 using a file transfer protocol, and stores the modified data in a modified data storage file 21 in the sub-host processing device 11.

The modified data editing and restoration processing unit 22 selects M from the modified data storage file 21 that matches the input format of the modification application processing unit 25.
The CS file 23 and relative file 24 are restored. As a result, the modification application processing unit 25 conventionally
Correction data provision magnetic tape 12 to MCS file 23
Then, the relative file 24 is read out and the program stored in the program storage file 26 is modified in the same way as the modified data is used.

[Effect]

According to the present invention, the modified data division and editing processing section 15 edits the modified data in basic units, so that the modified data can be managed correctly in the modified data storage file 16. Further, since unnecessary correction data and necessary correction data can be separated, the correction data transmission processing section 18 can send only the basic units of necessary correction data.

On the sub-host processing device II side, the received data is processed by the modified data editing and restoration processing unit 22.

Because it is converted into the input format of the modified general processing unit 25.

It has good compatibility with conventional systems that perform corrections directly from the correction data providing magnetic tape 12.

For example, assume that the contents of the modified data providing magnetic tape 12 shown in FIG. 1 are as shown in the MCS file 13 and each relative file 14 shown in FIG. 2. This MCS file 13 has data for batch correction and the like.

In MCS file 13, r++PROGRAMJ
The space between the sentence and the r++ENDPGMJ sentence corresponds to the rubel in batch correction. The modified data division/edit processing unit 15 shown in FIG. 1 uses this "++PROGRAMJ statement as a delimiter when dividing the modified data into basic units.

In the next r++PTF (AVO0135)l, the description of FILE is omitted, indicating that there is no relative file belonging to this modification, and that modification data follows this statement.

r++ENDPGMJ indicates the end of the modified data corresponding to "r++PROGRAM". In batch correction, the data up to this point becomes one basic unit of MCS data.

Continued < r++PROGRAM...” The following is the MCS data of the second basic unit. In this second batch modification, the same program as the first one, FORT77, is targeted for modification, and the batch modification level is V85071. Here, the modification number is UCOO124, and two relative files 14 belonging to this are specified.

In dividing/editing, the MCS data of the first basic unit in MCS file 13 and the file name UCOO123 are
