Abstract

PROBLEM TO BE SOLVED: To set again the configuration data at its previous value without inputting again a series of commands by a maintenance engineer when the previous configuration data is returned again in an environment where the discontinuation of the system work is not allowed. SOLUTION: When a recovery command is inputted to a system main body 1 from a command input device 5, a command execution part 2 starts a command emulation function 23 via a command analysis function 20. The function 23 erases the present configuration file 31 out of a file storage 3 and changes the name of a configuration file 31 preceding by one generation into the name of the file 30. Then the function 23 analyzes a series of commands to rewrite the contents of the file 30 and outputs these commands in sequence to the function 20.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a configuration data recovery device, and more particularly to a configuration data recovery method for returning rewritten configuration data to configuration data before rewriting.

[0002]

2. Description of the Related Art Conventionally, in this type of configuration data recovery method, a system is operated in an operating state.
If you simply rewrite the configuration data in memory using the previous generation configuration file,
Since the system malfunctions due to data during the transition period during rewriting, reset the system after changing the configuration file of the previous generation to the current configuration file, or enter a series of commands by the maintenance The value has been reset to the original value.

Here, the configuration data is, for example, an operating condition of each application in an exchange,
In other words, it indicates a condition for executing an operation such as which subscriber line is connected or what line is connected.

[0004]

In the conventional configuration data recovery method described above, when returning to the previous configuration data in an environment where the system is not allowed to stop, a maintenance person manually inputs a series of commands again, and You must reset the ration data to its previous value.

[0005] Therefore, an object of the present invention is to solve the above-mentioned problem, and when returning to the previous configuration data in an environment where the system is not allowed to stop, the maintenance person does not need to re-execute a series of commands. It is an object of the present invention to provide a configuration data recovery device capable of resetting configuration data to a previous value.

[0006]

A configuration data recovery apparatus according to the present invention includes a memory which is referred to by each application program and stores at least configuration data indicating an operation condition of each application program, wherein the configuration data is restored when a system is reset. A configuration data recovery device of an information processing system for reading and setting the configuration data from a file on a memory, comprising a holding unit for holding current configuration data, and a storage for storing configuration data of a previous generation. Means for rewriting data in the memory specified by the rewrite command when a command for rewriting the configuration data is input; Configuration data creation means for storing the configuration data held in the holding means when the storage command of the migration data is input and storing the configuration data on the memory in the holding means, Means for erasing the configuration data held in the holding means when the configuration data recovery command is input, and holding the configuration data of the previous generation stored in the storage means in the holding means; Means for controlling the configuration data rewriting means to rewrite the data in the memory with the configuration data of the previous generation held in the holding means when the recovery command is input.

As described above, the configuration data recovery apparatus using command emulation according to the present invention erases the current configuration file when a recovery command is input, and replaces the previous generation configuration file with the current configuration file. It has the function of rewriting the configuration file and rewriting the configuration file with the configuration data in the memory.

[0008] In addition, the configuration data recovery device by command emulation, when rewriting the configuration data in the memory, does not simply write the configuration file one generation before to the memory, but writes the data in the memory. It has a command emulation function that analyzes a series of commands necessary to rewrite the configuration and operates as if the configuration data was rewritten by the series of commands.

With this, when returning to the previous configuration data in an environment where the system cannot be stopped, the maintenance person can reset the configuration data to the previous value without re-entering a series of commands. It becomes possible.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In the figure, a command input device 5 is connected to a system main body 1, and a command execution unit 2, a file storage device 3, and a memory 4 are provided therein.

The command execution unit 2 has a command analysis function 20
, A configuration data rewriting function 21, a configuration file creation function 22, and a command emulation function 23.

The file storage device 3 stores a current configuration data file 30 and a configuration data file 31 one generation before, and the memory 4 stores configuration data.

When a maintenance person inputs various commands from the command input device 5 to the system body 1, a command execution unit 2
Then, the command analysis function 20 analyzes the input command. If the command is a command related to rewriting the configuration data in the memory 4, the configuration data rewriting function 21 is activated to rewrite the configuration data in the memory 4.

When the maintenance person wants to save the rewritten configuration data, he / she inputs a save command from the command input device 5 to the system body 1. Then, in the command execution unit 2, the command analysis function 20 activates the configuration file creation function 22, and the configuration file creation function 22 changes the name of the current configuration file 30 as the configuration file 31 of the previous generation, and The current configuration data on the memory 4 is saved as a configuration file 30.

After that, when the maintenance person wants to return the configuration data in the memory 4 to the state before saving, the maintenance person inputs a restoration command from the command input device 5 to the system main body 1. Then, in the command execution unit 2, the command analysis function 20 activates the command emulation function 23,
The command emulation function 23 deletes the current configuration file 30 and renames the configuration file 31 of the previous generation as the current configuration file 30.

At this time, the command emulation function 2
Reference numeral 3 reads the current contents of the configuration file 30, analyzes a series of commands necessary for rewriting the data, and sends the commands to the command analysis function 20 as if the series of commands were input from the command input device 5. Give instructions. As a result, the configuration data in the memory 4 is rewritten by the configuration data rewriting function 21 while the system main body 1 remains online.

For example, when rewriting line data (not shown), the line must be closed before rewriting the line data. Therefore, the maintenance person usually performs line closing, line data rewriting, and line blocking release. Three types of commands are input in that order.

The command emulation function 23 closes the line when the line data read from the current configuration file 30 is written into the configuration data in the memory 4 in the same manner as when the maintenance person rewrites the line data by a command. By passing the command to the command analysis function 20 in the order of the command, the line data rewrite command, and the line block release command, the line data can be transferred while the system main unit 1 remains online, as in the case of rewriting the normal line data. Rewrite the line data one generation ago.

As described above, the configuration data recovery device according to one embodiment of the present invention has the configuration file 31 of one generation before and emulates the command so that the system data 1 can be stored in the memory 4 even while the system main body 1 is operating. Can be returned to the previous generation of configuration data without performing a system reset or re-input of a series of commands.

FIG. 2 is a flowchart showing the operation of the command execution unit 2 of FIG. The command execution operation according to the embodiment of the present invention will be described with reference to FIGS.

When a maintenance person inputs various commands from the command input device 5 to the system body 1, a command execution unit 2
Then, the command analysis function 20 analyzes the input command (step S1 in FIG. 2), and if the input command is not a recovery command (step S2 in FIG. 2), the command execution unit 2
Then, a process corresponding to the input command is performed (step S3 in FIG. 2). This process is repeatedly executed until the process ends (step S4 in FIG. 2).

For example, if the input command is a command relating to rewriting of configuration data in the memory 4, in the command execution unit 2, the command analysis function 20 activates the configuration data rewriting function 21. Therefore, the configuration data rewriting function 21 performs an operation of rewriting the configuration data on the memory 4.

If the command is related to storage of configuration data rewritten by the above-mentioned rewrite command, in the command execution unit 2, the command analysis function 20 activates the configuration file creation function 22. Therefore, the configuration file creation function 22 changes the name of the current configuration file 30 as the configuration file 31 of the previous generation, and
An operation of saving the current configuration data on the memory 4 as the configuration file 30 is performed.

On the other hand, if the input command is a restoration command (step S2 in FIG. 2), in the command execution unit 2, the command analysis function 20 activates the command emulation function 23 (step S5 in FIG. 2), and the command emulation function 23 Configuration file 30
And the configuration file 31 one generation ago
Then, the part changed by executing the restoration command is extracted (step S6 in FIG. 2).

Thereafter, the command emulation function 2
3 deletes the current configuration file 30 (step S7 in FIG. 2), and renames the configuration file 31 of the previous generation as the current configuration file 30 (step S8 in FIG. 2).

The command emulation function 23 reads the contents of the current configuration file 30 (step S9 in FIG. 2), and analyzes a series of commands necessary to rewrite a changed part in the contents of the current configuration file 30. (Step S10 in FIG. 2), the series of commands are sequentially sent to the command analysis function 20 as if the series of commands were input from the command input device 5 (Steps S11 and S12 in FIG. 2).

As a result, the configuration data rewriting function 21 rewrites the configuration data in the memory 4 with the contents of the configuration file 31 of one generation before while the system main body 1 remains online.

For example, when rewriting data of a line (not shown), the line must be closed before rewriting the line data. Therefore, a maintenance person usually performs line blocking, line data rewriting, and line blocking release. Three types of commands are input in that order.

When the command emulation function 23 writes the line data read from the current configuration file 30 to the configuration data in the memory 4, the line emulation is performed in the same manner as when the maintenance person rewrites the line data by a command. The command is passed to the command analysis function 20 in the order of the command, the line data rewrite command, and the line block release command. As a result, the line data can be rewritten to the line data of one generation before, while the system main unit 1 is operating online, as in the case of rewriting the normal line data.

As described above, the configuration file 31 of the previous generation is provided, and the command is emulated by each function of the command execution unit 2 so that the configuration data in the memory 4 can be reset even while the system body 1 is operating. It is possible to return to the previous generation of configuration data without re-entering a series of commands or commands.

[0031]

As described above, according to the present invention, the holding means for holding the current configuration data, the storage means for storing the configuration data one generation before, and the command for rewriting the configuration data are input. Configuration data rewriting means for rewriting the data in the memory specified by the rewrite command when the configuration data is written, and storing the configuration data held in the holding means when the configuration data storage command is input, in the storage means. And a configuration data generating means for holding the configuration data in the memory in the holding means, and deleting the configuration data held in the holding means when the configuration data recovery command is input and storing the configuration data in the storage means Holds the configuration data of the previous generation in the holding unit, and controls the data in the memory to be rewritten with the configuration data of the previous generation held in the holding unit by the configuration data rewriting unit when the recovery command is input. When returning to the previous configuration data in an environment where shutdown of the system is not allowed, the maintenance person can reset the configuration data to the previous value without re-executing a series of commands. There is an effect that can be.
