Switching system of system file

[Detailed Description of the Invention]

The present invention relates to the change method of the system program file of an electronic computer system (a temporary Nirimort processor is called) by which remote control is carried out. Although operation of the system controlled by Converter is ordered by the program and it performs, if functions are added and reduced by the system, a system program file (carrying out abbreviated system file) will also be changed. Operation of a system is once interrupted to change this system file conventionally, The operator needed to do loading of the new program to the disk through the panel, and needed to do from the disk IPL to the memory (main memory) of a remote processor (initial program loading). This has the problem of A(ing) a help other than cessation of operation, and does not meet the trend of laborsaving and a full automation inclination. The present invention tends to eliminate cessation of operation and panel IPL, tends to enable the change of a program file by a program during system operation at another it, and tends to provide the method which enables long-term continuation of a remote processor, completeness, or semi- full automation operation. That is, in the change method of the system program file of the electronic computer system by which remote control of the present invention is carried out, It is a command, if the 2nd recording medium of preservation business other than the 1st recording medium that stores a file in the system during operation is formed and it is in charge of a system file change, A file is stored in the 2nd recording medium during operation from the 1st recording medium, and the permanently non-residing control to the main memory of the system is changed from the former to the latter, Current file information and a following IPL load course are also changed into the latter, and a new file is stored in the 1st recording medium by Or \ State, Although characterized by also changing initial program low Dingshi, current file information, and a following IPL load course into the 1st recording medium from the 1st recording medium of after [ appropriate ] to the above-mentioned main memory, and usually going into operation, this is explained in detail, referring to drawings next. Drawing 1 shows the hardware image of the Converter control system with which the present invention is applied. RP is a remote processor and is processor unit PU. It has console C8L (it may not exist), magnetic tape handler MT (it may not exist), magnetic disk drive DK, DK, and DK3 (it may not exist). Although the program which manages system operation was improved (renewal of a generation) and To and plog love [ with built-in remote processor PTJ ] - were switched to a new program, conventionally, this work interrupted operation and the operator was performing it using console C8L. In the present invention, it is the following point about this using operator vicarious execution program posp, and they are completeness or a thing which it tries to perform dynamically repeatedly, without interrupting operation. When this is explained with reference to Drawing 2, (a) shows IPL operation and this is Oh, the 1/of What-evening switches on a power supply -- To -- natural -- power turn-on ON may be carried out by the instructions from a control electronic computer system -- the program stored in panel operation in Like disk DK is inputted into main \ memory M of PU, and is performed. The offer place (current file information) of the program inputted into memory M is recorded on the table (not shown). When rebooting after a system failure, a system program needs to carry out IPL using a function Incompetent in IPL directions by a program. To the trouble under system operation, this reboots automatically rather than stops operation unconditionally, and it changes it into the state where the directions about continuation of operation after it can be received. The information on IPL Case is registered into the external register (not shown) which is not cleared in the time of system reset, either from load course Tsunami DKm of the IPL. Disk DK and Is now are in an unused state, and disk DK and a (reserve side) have the always same contents as disk DK1. the example of a system of Tsubasa has taken the dual system for the improvement in stability (the case where a dual system is not taken -- DK -- it does not There is). (b) usually shows in operation. Although the program by which IPL was carried out is contained in the resident part of memo IJ M, a required program is read from disk DKl to a non-resident part, and is loaded to it each time. This permanently non-residing control is Let's go and go to the current file information of the above-mentioned table. (e) is a system. The 1st step of a program file switch is shown and possession side creation is first performed like illustration in this change. That is, file transfer of the contents of disk DK or DK, is carried out in DK, performing permanently non-residing control (loading) from disk DK to memory M. This is a working side (DKI). It is for It's simple fi of the control at the time of the employment a reserve side (DK8) and in respect of preservation (DKz), DKl, DK2. DK, and each to use a disk fixed, without changing the control information (information required in order to perform reserve side control at the time of IPL, etc.) currently held on a disk. Next a system file change command is issued and it performs a file switch. In semi- full automation, a command supplies from a console, and, in full full automation, it transmits from a control electronic computer system. Instead of DKl which enables oven and the lead of the storage area of disk DK, called the 2nd page as a file switch is shown in (d) which spreads, and calls it X side, Z@DK, is made to carry out permanently non-residing control to memo IJM. The current file information of the above-mentioned table is changed into the 2nd page. Changing into the 2nd page the following IPL load course registered into the above-mentioned external register, X side file closes. Drawing 3 is a flow chart which shows this change processing point. It goes into new file creation after a file switch. (-- disk DK where) was closed in this state, Loading of the new file is carried out to DK3. It is renewal file id at this example : It goes into i Stape, and I hear that this is written in IK and DK with A harness picking, and it performs it. Since a help performs magnetic tape wearing to MT, although full automation does not have Sashimi, magnetic tape is ashore ON t Set to MT, and it is only To! By a program, the Emergence amateurs of processing of 2Ri and after that are enough as a line, and it does not need a specialist. A new file can be transmitted to a remote processor through a communication line from a control electronic computer system, this may be loaded to DK and DK, and it can automate fully in this case. In the meantime, permanently non-residing control is performed from 2 Therefore. Although the change to a new file is performed after that, as shown in (f), this specifies X side, issues an IPL directions command, and from operation by the help from a panel, and X side after a system blockade, IPL of the Conventional is carried out and it performs it. In the example of a load course book by which Over IPL was carried out to the above-mentioned external register, current file information (X side) is written in a prefecture lump and a table, and DKl is usually gone into operation below. As explained above, in the present invention, a display is provided in a file during a run during system operation (current file ffN of a table), When access to a system file is needed during system operation, suppose that it is accessible to the file which the display shows with reference to the display, In a change, possession side creation is performed first, and, subsequently it is after oven processing of a change place system file (preservation side), Changing a display into a change place system file during a run, the system file which was under operation closes, Loading of the new file is carried out to the recording medium of the closed system file, and permanently non-residing control is performed from the preservation side between these, and IPL is carried out from the above-mentioned recording medium, and it usually goes into operation, and directs these change processings by a command. Therefore, the discontinuation of the system of operation is not carried out except for the time of IPL operation of a new file, continuation operation is possible, and completeness or semi- full automation processing is possible. the closed old file storing recording medium -- Drawing 2 -- (-- since it is equivalent to disk DK during the pause of), the return to the old file is also possible by updating to a new Every file being also possible, or specifying a preservation side by operation, similarly, using this, and issuing an IPL directions command. System operation was interrupted, loading of the new file of disk DK1 was carried out, the appropriate back carried out IPL from the disk DK1, operation of going into operation was required, the conventional system file change method took the help, and discontinuation time was long. In this point present invention, it is [ that it is loading of the new system file to a file, and ] ready for a file update during system operation, continuing system operation. And re-starting by an updating file can be directed by the command injection from a control electronic computer system or a console. When not taking the Puer system, it is DI (the above-mentioned method is applicable by excluding the processing to 3.).
