The information management unit 21 has a device information storage unit 22. The communication unit 20 exchanges data with the device communication unit 17 of the personal computer 12.
As the device information storage units 18 and 22, for example, hard disks are used.

  Here, the management means is means for managing device information related to the device and account information for accessing the device, and the changing means is means for changing the account information based on the device information and account information acquired from the management means. The handling means is means for changing the account information after accessing the device that has failed to change using the account information before the change when the change of the account information of the device has failed. These management means, change means, and response means are included in the device management software 15. For example, in FIGS. 2 and 3, the management means corresponds to step S203, and the change means corresponds to step S202. The responding means corresponds to step S209.

[Operation]
FIG. 2 is a first half common part of the sequence diagram for explaining an example of the operation of the device management apparatus shown in FIG. 1, and FIG. 3 is an example of the second half of the sequence diagram shown in FIG. FIG. 2 shows the relationship between the user 10, the web page generation unit 14, the device management unit 16, the device A 19a, and the device B 19b. FIG. 3 shows the user 10, the web page generation unit 14, the device management software 15, the device A 19a, and the device. The relationship of B19b is shown. FIG. 4 shows an example of the password change request screen 40.

In the present embodiment, a case where the password is changed from “1234” to “ABCD” will be described.
In FIG. 2, after the user 10 logs in the web page generation unit 14, a key operation for acquiring information (device information) of a device whose account information is to be changed is performed. The web page generation unit 14 sends a signal for acquiring device information to the device management software 15 of the personal computer 12 (see FIG. 1). The device management software 15 accesses the device A 19a and the device B 19b, respectively.
The user 10 requests the web page generation unit 14 to change the password as account information (see step S201, password change request screen 40 in FIG. 4).
The web page generation unit 14 issues a password change request to the device management unit 16, and the device management software requests the device A 19a and the device B 19b to change the password, respectively. Assuming that the device A19a is operating normally, the device A19a changes the password and sends a signal to the device management software 15 that the password has been successfully changed. The device management software 15 updates the internal device information. That is, the device management software 15 updates the access account information table of each device (step S202), and stores the information acquired by the device communication unit in the device information storage unit (step S203).

  On the other hand, when the device management software 15 fails to change the password for the device B 19b due to power off or timeout, the device management software 15 holds password change failure information (step S204). That is, since the device B 19b has failed to change the password, the password remains “1234” (step S205).

  In FIG. 3, when the user 10 acquires device information from the web page generation unit 14, the web page generation unit 14 acquires device information from the device management software 15. When the device management software 15 accesses the device A 19a, since the device A 19a is a device whose password was successfully changed last time (password = “ABCD”, step S206), it can be accessed with the new password “ABCD” (step S206). -1).

Since the device management software 15 has acquired the password change failure information, it requests the device B 19b to change the password again. Since the device B 19b is a device (password = “1234”) whose password change failed last time (step S207-1), the device management software 15 changes the password. That is, (1) Authentication with old password “1234”, (2) Authentication OK, (3) Change password to “ABCD”, (4) Change password in order of change (“1234” → “ABCD”) Performed (step S209-1).
After the password change, when the user 10 acquires device information from the web page generation unit 14, the web page generation unit 14 acquires device information from the device management software 15. The device management software 15 can access the device A 19a and the device B 19b with the new password “ABCD” (step S210-1).

  As described above, according to the present embodiment, the change failure information is acquired by changing the account information after obtaining the change failure information and accessing the device that has failed to change using the account information before the change. Since no access is made, the account information of the device that failed to be changed can be changed reliably.

[Second Embodiment]
〔Constitution〕
FIG. 5 is an explanatory diagram of normal management when accessing a device using an old password in the device management apparatus, and FIG. 6 is an explanatory diagram of password change in the device management apparatus. FIG. 7 is an explanatory diagram of normal management when accessing a device using a new password in the device management apparatus, and FIG. 8 is an explanatory diagram of changing the new password in the device management apparatus.
In the present embodiment, the password is changed from “1234” to “5678”.

As shown in FIG. 5, the user 10 accesses the personal computer 12 to the device 1 (30), device 2 (31), and device 3 (32) as devices. In the account information in this case, the user name is “Hagiwara” and the password is “1234”. Further, the personal computer 12 acquires the status (start session (user name, password “1234”), get object (status)).
Account information is transmitted from each device 1 to 3 (30 to 32) to the personal computer 12. For the administrator access accounts of the devices 1 to 3 (30 to 32), the user name is “Hagiwara” and the password is “1234”.

  As shown in FIG. 6, when the user 10 instructs the personal computer 12 to change the password “1234” of each device 1 to 3 (30 to 32) from “1678” to “5678”, the personal computer 12 instructs each device 1 to 3. A password change instruction (start session (user name, password “1234”), put object (new password “5678”)) is sent to (30 to 32). The account for accessing the devices 1 to 3 (30 to 32) as devices has a user name “Hagiwara” and a password “1234”.

Among devices 1 to 3 (30 to 32), device 1 (30) and 2 (31) were able to change the password from "1234" to "5678", while device 3 (32) was powered on Suppose the password could not be changed for some reason. That is, the password of the device 3 (32) remains “1234”.
As described above, among the devices 1 to 3 (30 to 32), the passwords of the devices 1 (30) and 2 (31) are “5678” and the password of the device 3 (32) is “1234”. When the user 10 tries to access each of the devices 1 to 3 (30 to 32) with the new password “5678”, only the device 3 cannot be accessed.

A case where the password could not be changed will be described with reference to FIG.
If the password could not be changed, keep the previous password (pre-change password) and change the password every time the status is acquired (status acquisition is performed at a fixed time (for example, 1 hour) by default). However, in this case, since the password change process is performed every time, the password is changed every time the status is acquired).
That is, when the user 10 accesses the devices 1 to 3 (30 to 32) with the user name “Hagiwara” and the password “5678”, the personal computer 12 refers to the list of devices whose password could not be changed. In the device list, the device name of the device 3, the old password “1234”, and the new password “5678” are stored.
The personal computer 12 accessed the old password (user name, password = 1234) for the "start session" of the device 3 (32) whose password could not be changed, and changed the new password to "5678" in the "put object" After that, similarly to the devices 1 (30) and 2 (31), the device 3 (32) can be accessed with the new password “5678”.

  Here, in the device management software, the password of all devices is “1234” as shown in Table 1 before the password change, and the passwords of the devices 1 and 2 among the devices after the change are “5678” as shown in Table 2. Thus, the password of the device 3 is “1234”. As shown in Table 3, the current access account information of the device management software has a user name “Hagiwara” and a password “5678”. Regarding the data shown in Tables 1 to 3, the data in Table 1 is stored in the device information storage unit of each device before the change, and the data in Table 2 is stored in the device information storage unit of each device after the change. The data of FIG. 3 is stored in the device information storage unit 18 of the personal computer 12.

  In the present embodiment, the same effect as in the first embodiment can be obtained.

[Third Embodiment]
A third embodiment of the device management apparatus according to the present invention will be described.
Since the hardware configuration is the same as that of the first embodiment, a description thereof will be omitted.
This embodiment refers to the access account information table of each device, acquires change failure information, and periodically changes the account information after accessing the device that failed to change using the account information before the change. It is equipped with software.

FIG. 9 shows another example of the latter half of the sequence diagram shown in FIG.
The operation of the present embodiment can be described with reference to the sequence diagram of FIG. 2 and the sequence diagram of FIG. 9. Steps S201 to S205 in the sequence diagram shown in FIG. Since it is the same as that, the description is omitted.
In FIG. 9, device A19a is a device (password “ABCD”) for which the previous password change was successful (step S206-2), and device B19b is a device (password “1234”) for which the previous password change failed (step S207). -2).

  The device management software 15 has acquired the password change failure information, refers to the access account information table of each device A, B (19a, 19b) (step S208-2), and sets the periodic password change time interval. It is set in advance (timer function), and the passwords of the devices A and B (19a, 19b) are automatically changed at the timing of the timer (step S209-2). By this periodic password change, the password of the device A 19a is changed from “1234” to “ABCD” (step S211-2). Thus, when the user 10 acquires the device information and the web page generation unit 14 acquires the device information, the device management software 15 can access the device A 19a and the device B 19b with the new password “ABCD” (step S211- 2).

  In the above, according to the present embodiment, re-access failed again by acquiring change failure information and periodically changing the account information after accessing the device that failed to change using the account information before the change. However, since it is re-accessed and changed again, the account information of the device that failed to be changed can be changed more reliably.

[Fourth Embodiment]
A fourth embodiment of the device management apparatus according to the present invention will be described.
Since the hardware configuration is the same as that of the first embodiment, a description thereof will be omitted.
The difference between the present embodiment and the first embodiment is that “acquisition of device status” in the first embodiment is an internal process that is not directly visible to the user, and a process for changing to a new password is performed therein. For this reason, the user is unaware of whether or not the password has been changed, and the device status acquisition process is performed at a predetermined time (for example, every hour) by default, and the password change process is performed each time. On the other hand, the fourth embodiment is different from the first embodiment in that the user intentionally performs “password change” processing on the application.
In this embodiment, a web page generation unit that receives a re-change instruction for re-changing account information of a device that has failed to be changed from the user, and a re-change instruction from the web page generation unit, the access account information table for each device It is provided with device management software that refers to, acquires change failure information, accesses the device that failed to change using the account information before the change, and then changes the account information.

FIG. 10 shows another example of the latter half of the sequence diagram shown in FIG.
The operation of the present embodiment can be described with reference to the sequence diagram of FIG. 2 and the sequence diagram of FIG. 10. Steps S201 to S205 in the sequence diagram shown in FIG. Since it is the same as that, the description is omitted.
