Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for replacing an online file created by a debug station in an operation station. In order to implement new services and exchange functions in NTT with the development of the exchange, the debug exchange performs various functional tests in the development environment, and the actual exchange operates the debug results and inserts them. There is.

FIG. 5 shows a system configuration example of a debug station and an operation station. In the figure, 11 is a debug station, 12 is an operation station,
Reference numeral 13 indicates a file for the external storage device of the debug station, and 14 indicates a file for the external storage device of the operation station. In order to execute various function tests in the development environment in the debug station 11 and insert and debug the debug results, a file for external storage device
It was written in 13 in the online format, converted into an offline format file, provided as the external storage device file 14 of the operation station 12 in various places, and carried out all at once.

A file created as a file replacement original by the debug station is an online format file, and a new file to be operated and implemented by the operation station is an offline format file, from an online format file to an offline format file. The work to convert to was necessary in the debug station. A dedicated conversion tool was required for this format conversion.

2. Description of the Related Art FIG. 6 shows a conventional procedure for creating an online file replacement method. In the figure, 'Create a file replacement original file (online format) at the debug station. Create a new file by inputting online from the memory of the active system to the file of the external storage device of the standby system. 'In the debug station, convert the newly created online original file into an offline original file using a conversion tool. 'In the operation station, in order to replace the file, insert the original file in the offline format into the external storage device of the standby system and pull it up as a new file in the memory of the standby system. 'At the operation station, switch the active system and the standby system and start operation with the new file. The contents of the active system memory and standby system memory are made the same, and the new file replacement is completed.

Next, FIG. 7 shows a comparison between an online format file and an offline format file. In the figure, in the online format file that is normally used,
Assuming that the data A, B, C, D, ... Are input, the offline format file is created by converting the memory allocation information for each data into a file to which the data is assigned by the conversion tool. That is, allocation information, A, allocation information,
A file is created by inputting B, allocation information, C, ...

[0006]

In the conventional online file replacement method, a debug station temporarily converts an online format file into an offline format file using a conversion tool, and the operation station uses this new offline format file. I was swapping files. For this reason, it is necessary to read the offline file to which the allocation information is added.

According to the present invention, when files are replaced,
The purpose of the present invention is to change the online processing from the conventional offline file reading processing to the existing file pulling processing, omit the procedure of converting the file format, and simplify the work of creating a supply file.

FIG. 1 shows a principle block diagram of a file replacement system in an operation station according to the present invention. The figure shows the connection configuration diagram of the operating and standby exchanges. Fig. 1 (a) shows the new file reading procedure of the exchange, and Fig. 1 (b) shows the new file operating procedure of the exchange. In the figure, 1 is an operating exchange,
2 is a standby exchange, 3 is main memory, 4 is CPU, 5
Is an external storage device, and 6 is an update file.

In the new file reading procedure of FIG. 1 (a),
Is a means for mounting the update file 6 in the external storage device 5 of the standby system exchange 2, is a means for reading the update file 6 from the external storage device 5 of the standby system exchange 2, and is a means for reading the read contents of the standby system exchange 2. In the new file operation procedure of the exchange shown in FIG.
Indicates a means for switching the main memory 3 and the CPU 4 of the standby system 2 to the active system and starting the operation with the new file 6.

[0010]

FIG. 2 shows a processing flowchart of the operation station of the present invention. (1) The debug station creates the update file 6 by a normal online file and supplies it to the operation station. (2) Install the update file 6 in the external storage device 5 of the standby system 2 at the operation station. (3) From the external storage device 5 of the spare system 2 to the CPU of the active system 1
4 reads out one sector, and saves from which sector it is read. (4) Main memory 3 of the backup system 2 from the read sector number
Calculate the assigned address. (5) Write the data of the sector to the allocation address of the main memory 3 of the standby system 2 calculated by the CPU 4 of the active system 1. (6) Check if the file reading is completed,
If the reading is not completed, the next sector is read. (7) When the reading is completed, the main memory 3 and the CPU 4 of the standby system 2 are switched to the active system, and the operation is started by the new file stored in the main memory 3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the present invention and the conventional example are different from the principle configuration processing means in FIG. 1, FIG. 3 shows the difference between the embodiment of the normal file and the embodiment of the offline format file. In the figure, a normal file has 0th sector (abc ...), 1st sector (def ...), 2nd sector (ghi ...), 3rd sector.
When it is composed of sectors (jkl ...), the 0th sector becomes the allocation information of the 1st sector in the offline format file, (abc ...) is allocated to the 1st sector, and the 2nd sector is allocated. It becomes the allocation information of the second sector, and it becomes the third sector.
(def ...) is assigned.

The basic operation of file replacement has the following agreement when a new file is read from the external storage device.
That is, (1) For reading, one sector or several sectors are read from the storage medium. (2) The size of the read file is undefined. (Read until the last sector is found.) (3) Do not consider the sector position of the read contents. (Does not care which sector the data was read from.) (4) Do not care where in the main memory the read data is allocated.

Therefore, it is necessary to have the allocation position of the read sector for each sector without knowing the allocation position. The file format that contributes this allocation information to each sector is a conventional file of the offline format. When creating this offline format file, a normal file must be converted by a tool. By supplying the file to be supplied when exchanging files as a "normal file" instead of the "offline format file", the file creation time can be shortened and the file replacement time can be shortened.

In the case of the conventional offline file format,
The sector position of the read content is not taken into consideration, and the location of the read content is not considered (does not care which sector is read). However, in the present embodiment, the sector position of the read content is Paying attention to the above, the allocation address of the main memory is calculated from the saved sector number (which sector is read out is saved).

An embodiment of the file reading method of the present invention is shown in FIG.
Shown in. In the figure, assuming that one sector of the storage medium is 256 words, a method of writing the data read from the second sector of the storage medium to the address of the main memory will be described. In the figure, one sector is read from the second sector of the storage medium. The allocation address of the main memory is calculated from the sector number read from the second sector. 256 (words) x 2 (sectors) = 512 (addresses) The second is assigned to the calculated allocation address 512 (address) of the main memory.
Write a sector. The sector reading is continued until the file reading from the storage medium is completed.

[0016]

As described above, the procedure of converting the conventional online file format to the offline format to supply the file is unnecessary, the work of creating the supply file is facilitated, and the work time is shortened.
