DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for executing the same operation command and a method of using the same, and more particularly to a device for executing the same operation command which is a command for requesting the same operation to a plurality of host machines in a computer network system and the use thereof. About the method.

[0002]

2. Description of the Related Art As an example of a conventional same operation command execution apparatus, that is, a technique for causing a plurality of host machines to execute a command requesting the same operation, for example, Japanese Patent Publication No. Sho 58-3
There is a technique described in US Pat.

The technique disclosed in the above publication is a data communication process in a multi-computer system in which data can be simultaneously communicated to a plurality of sub-systems in a multi-computer system that performs communication between subsystems using a single bus. This is related to the system, and its outline is described below.

[0004] The single bus includes a data line and a control line for transmitting and receiving control information indicating whether information on the data line is data information or other command information or response information. It is composed of

[0005] When performing simultaneous communication, the transmitting subsystem first sends control information indicating that the data on the data line is command information or response information on the control line, and transmits each receiving subsystem on the data line. It sends out data transfer command information addressed to it individually.

When each receiving subsystem receives data transfer command information addressed to its own subsystem, it sends response information on the data line in response to the command.

Next, the transmitting subsystem transmits control information indicating that the data on the data line is data information on the control line, and simultaneously transmits the same data addressed to each receiving subsystem on the data line simultaneously. Thereafter, the transmission subsystem sends control information indicating that the data on the data line is command information or response information on the control line, and also sends data end command information destined for each reception subsystem on the data line.

When each receiving subsystem receives the data end command information addressed to its own subsystem, it sends response information on the data line in response to the command.

Thus, Japanese Patent Publication No. 58-36375
In the technique described in the publication, the same operation of data reception is performed by a plurality of subsystems connected in parallel to a single bus.

[0010]

In the above-mentioned conventional operation command execution device, upon reception of data, only the confirmation of data transfer as to whether or not the reception of the transfer data has been completed normally is performed. Even if a command requesting the operation is transmitted as data, it does not have a function of acquiring confirmation of the execution result of the command, so a command for simultaneously executing the same operation on a plurality of devices, so-called the same operation There is a disadvantage that the command is limited to only a command instructing an operation of receiving transfer data, and does not act on a command instructing another operation.

There are a number of executions of the same operation on a plurality of host machines on the same network, such as environment setting and backup processing. For these operations, an operator must execute the necessary operations for each host machine. On the other hand, if the number of target host machines is large, the number of operations increases, which is complicated.

Further, the conventional same operation command execution device can identify the abnormal subsystem when data transfer to a certain subsystem fails, but the abnormal subsystem remains failed. This is a state different from that of other subsystems to which data transfer has succeeded, and there is a disadvantage that synchronization between the subsystems cannot be achieved.

Also, two lines are required: a control line for passing control information indicating whether the data to be transferred is a command or a response or data, and a data line for passing data to be transferred. Therefore, data can be transferred only between subsystems connected in parallel with a single bus,
It has the disadvantage of being limited to a specific network configuration.

An object of the present invention is to execute a command for requesting the same operation to a plurality of host machines in the same network system, and to ensure the synchronization of the state of each host machine with respect to the execution result. And a method of using the same.

[0015]

According to a first aspect of the present invention, there is provided an identical operation command execution device for executing an identical operation command which is a command for requesting and executing the same operation to a plurality of host machines in the same network system. In the operation command execution device, a host configuration storage unit that stores an identifier of the host machine to be subjected to the same operation, a user identifier and a password at the time of logon thereof, and a directory of the target host machine that executes the same operation. A directory storage means for storing for each of the target host machines, and the target host machine logging on and logging on to the target host machine by referring to the host configuration storage means in response to a start request for executing the same operation supplied from outside Check the consistency between the directory and the directory storage means. The same operation start instructing means for instructing the start of the same operation when the target host machines are consistent, and otherwise instructing to log off all the target host machines and to stop the execution of the same operation, In response to the same operation execution start instruction from the start instruction means, a command input from the outside is supplied to all the target host machines and executed, and when the execution is successful on all the target host machines, the process proceeds to the next processing. At other times, the same operation execution means for restoring the states of all the target host machines to a state before the supply of the same operation execution start instruction according to a command input from the outside and displaying the same operation execution failure display instruction, Log off all the target host machines in response to the same operation end request supplied from outside and display the same operation end display It is configured to include a same operation end means that.

The method of using the same operation command execution device according to the second invention is such that, when the same operation command execution device is used to create a directory on the same operation target host machine, a start request for the same operation execution is first made, Next, a directory creation command is supplied, and if there is an identical operation target host machine that has failed in execution, a directory deletion command is supplied to delete the newly created directory on the same operation target host machine that has succeeded in execution, and then a termination request of the same operation is issued. It is characterized by doing.

The method of using the same operation command execution device according to the third invention is the same as that of using the same operation command execution device but causing the same operation target host machine to delete or copy a file. Then, the save command of the target file is supplied, then the delete or copy command of the target file is supplied, and when the delete or copy command of the target file is successfully executed on all the target host machines, A delete command for the file saved by the save command is supplied, and a restoring command for the file saved by the save command is supplied at other times, and then a request for terminating the same operation is made.

A method of using the same operation command execution device according to a fourth aspect of the present invention is that, when a file in the same operation target host machine is edited using the same operation command execution device, first, a request to start the same operation execution is made. Then, the transfer command of the target file is supplied, then the same operation end request is made, then the transferred file is edited, then the start of the same operation is requested, and then the edited file is sent. A file transfer command is supplied, and when there is the same operation target host machine in which execution of the edited file transfer command has failed, a delete command of the edited and transferred file is supplied, and then a same operation end request is issued. It is characterized by doing.

[0019]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the same operation command execution device according to the present invention.

As shown in FIG. 1, the same operation command execution device 1 of this embodiment works in cooperation with a plurality of host machines 8 (for example, hosts A, B and C).

The same operation command execution device 1 includes a directory file 5, a host configuration file 6, the same operation start instructing means 2, the same operation command execution means 3, and the same operation end means 4. .

The host configuration file 6 stores in advance the host machine name of the host machine 8 to be subjected to the same operation, and the user name and password for logon for each host machine.

When a target host machine is added or deleted, the target host machine can be easily changed by updating the host configuration file 6.

Since the host machine that executes the same operation command is specified by the host configuration file 6, it can be the target of the same operation command in any network configuration as long as they are connected by the same network. .

In the directory file 5, directories for executing the same operation are stored in advance for each host machine.

If the directory in which the same operation is performed is changed, the same operation command is executed in the changed directory by changing the directory file 5.

The same operation start instructing means 2 makes preparations for starting the same operation.

When the start of the same operation is requested, the same operation start instructing means 2 logs on all the target host machines based on the host configuration file 6 and checks the consistency of directories of all the host machines 8 by the directory file 5. To check. When the same operation start instructing means 2 ends normally, the start of the same operation is instructed to be displayed, and all subsequent operations are recognized as the same operation command.

The same operation command execution means 3 transmits the requested command (creation of a directory, copying of a file /
A command is created in response to the deletion, editor, etc.), and the command is transferred to each host machine 8 based on the host information stored in the host configuration file 6.

When the processing is completed normally in all the host machines 8, the display of the success of the same operation command is instructed. If any one of the host machines 8 has failed, the host machine 8 is returned to the state before the execution of the command, and the display of the failure of the same operation command is instructed.

The same operation ending means 4 performs the same operation ending process.

When the end of the same operation is requested, the same operation end means 4 logs off all the target host machines 8 based on the host configuration file 6 to end the same operation, and instructs the end of the same operation to be displayed. Then, the same operation ends.

Next, the operation of the same operation command execution device according to the present embodiment will be described with reference to FIG.

First, the same operation start instructing means 2 prepares for the start of the same operation.

FIG. 2 is a flowchart showing the operation of the same operation start instructing means 2.

When receiving a request to start execution of the same operation (step 21), the same operation start instructing means 2 creates a logon command using the user name and password in the host configuration file 6 and transfers it to all target hosts. Each is logged on (step 22).

If the logon is successful (Y in step 23)
ES branch), the consistency between the directory on each host machine 8 and the information in the directory file 5 is checked (step 24).

If the consistency check between the logon and the directory is completed normally (YES branch of step 25), a display instruction is given to start the same operation (step 26).

All commands input thereafter are recognized as the same operation command.

If at least one of the host machines 8 failed in the logon or directory check (NO in step 23 or step 25).
NO branch), the execution is stopped. That is, create a logoff command, transfer the command to the target host machine,
Each of them is logged off (step 27), and an instruction is given to display the failure of the same operation.

An abnormality such as the power of the target host machine 8 not being turned on or a high load on the host machine 8 has occurred and the host machine 8 cannot perform the same operation.
Fails to log on. Thereby, it is possible to confirm whether there is a host machine 8 that cannot perform the same operation.

In order to check the consistency of the directory in the directory file 5 (step 2).
4) It is not necessary to check when each identical operation command is executed, and errors due to directory mismatch can be prevented.

As described above, the check is performed by the same operation start instructing means 2 before execution, and if there is a host machine 8 that can not execute the same operation, the same operation is not started. Therefore, among the target host machines 8, only the host machine 8 capable of performing the same operation does not execute the same operation, so that all the target host machines 8 can be kept in the same state.

The execution of the same operation command is performed by the same operation command execution means 3. FIG. 3 is a flowchart showing the operation of the same operation command executing means 3.

To execute one process, N (N = 1)
This can be achieved by executing the above (integer) commands, and the operator inputs the commands in order from the first command. In response to this, the same operation command executing means 3 first transfers the first command to a plurality of target host machines 8 (steps 31 and 32), and receives a response indicating success of the execution result from all the target host machines 8. Then (YES branch of step 33), the second command and the N commands constituting the process are executed sequentially (YES branch of steps 32 and 33, NO loop of 34 and 35), and When the execution of all the commands is completed successfully (YES branch of step 35), the execution result is instructed to be displayed (step 37), and the process ends.

However, in step 33, if even one of the target host machines 8 fails to execute the command (NO branch of step 33), the operator inputs a command to return to the state before the start of this processing, and This command is transferred to all the target host machines 8 by the same operation command executing means 3 (step 36), the state of all the target host machines 8 is returned to the state before the start of this processing, and a failure display instruction of the same operation is issued. Go (Step 3
7), end.

Next, with reference to FIG. 5 will be described three examples of processing method according to the same operation command executing means 3.

FIG. 5 shows a directory creation process.
In the directory command processing shown in (a), the file copy or deletion processing can be divided into the file command processing shown in FIG. 5B, and in the editor processing, it can be divided into the editor command processing shown in FIG. 5C. In the following description, the restoration processing operation at the time of failure may be omitted for convenience.

Next, the details of each operation will be described.

First, the directory command processing will be described with reference to FIG.

Based on the input command, a directory creation command is created and transferred to each host machine 8 (step A1). If directory creation is completed normally on all target host machines 8 (YES branch of step A2),
Display and instruct the success of the same operation command (step A
4).

If there is any host machine 8 that failed to create a directory (NO branch of step A2), a directory deletion command is created based on the input command in order to return to the state before the command was executed. Transfer to the host machine 8 where the directory has been successfully created (step A
3), display indication of failure of the same operation command.

Next, a file command process for copying or deleting a file will be described with reference to FIG.

In order to save the target file based on the input command, a file save command is created, transferred to each host machine 8, and the target file is saved (step B1). Next, a file copy command is created when copying a file, and a file deletion command is created based on the input command when a file is deleted, and transferred to all host machines 8 (step B2). If the execution results of all the target host machines 8 are completed normally (YES branch of step B3), a file deletion command is created based on the input command in order to delete the saved file, and each host machine 8 Transfer,
The evacuation file is deleted (step B4), and the display of the success of the same operation command is instructed (step B6).

If there is any host machine 8 that failed to copy or delete the file (NO in step B3)
Branch), in order to return to the state before the command execution, a command for returning the saved file to the original file is created based on the input command, and transferred to each host machine 8 (step B).
5), display failure indication of the same operation command (step B6).

Next, an editor command process will be described with reference to FIG.

If the file editing process is performed by each of the host machines 8, the transmission and reception of data between the same operation command execution device 1 and each host machine becomes congested, resulting in inefficiency. First, a command to transfer the file to be edited to the same operation command execution device 1 is created based on the input command, and the created file is transferred to each host machine 8 so that the target file is copied to the same operation command execution device 1. 1 (step C1). When there is no file to be edited (NO in step C1), a file to be edited is newly created (step C3).

The files collected in the same operation command execution device 1 are edited by the input editor command (step C4).

After completion of the editor, a file transfer command is created based on the command input for transferring the edited file and transferred to each host machine 8 (step C5). If normal (YES branch of step C6),
Display and instruct the success of the same operation command (step C
8). In the case of failure (NO branch of step C6), a transfer file deletion command is created based on the input command and returned to before the editor processing (step C7), and an indication of failure of the same operation command is displayed (step C8). ).

Steps C3 and C4 are operations performed by devices other than the same operation command execution device 1, and are not the same operation operations. Therefore, in this case, the same operation is performed in two stages, the operation before step C3 or C4 and the operation after step C3 or C4.

As described above, the execution result of the command can be received by the same operation command execution means 3, so that the execution result is guaranteed. Therefore, the same operation can be performed on a plurality of target host machines 8. Further, if any one of the host machines 8 has failed in executing the same operation command, the host machine 8 is returned to the state before the execution, so that all the target host machines 8 can be kept in the same state.

When the execution of the same operation command ends, the same operation ending means 4 is requested to end the same operation. FIG. 4 is a flowchart showing the operation of the same operation end means 4.

When the same operation is completed (step 41),
A logoff command is created and transferred to each host machine 8 to log off all target host machines 8 (step 42), display the termination of the same operation (step 43), and terminate the same operation.

As described above, the same operation command execution device of the present embodiment has an effect that a command for requesting the same operation to a plurality of host machines in the same network system can be executed.

Further, when the execution result is unsuccessful, by returning to the state before the execution, the synchronization of the states of the respective host machines can be ensured.

[0067]

As described above, the same operation command execution device and the method of using the same according to the present invention have an effect that a command for requesting the same operation to a plurality of host machines in the same network system can be executed. are doing.

Further, when the execution result is unsuccessful, the state of each host machine can be synchronized by returning the state to the state before the execution.
