Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a down line loading (hereinafter DLL) control system, and more particularly to a DLL using a graphical user interface (hereinafter GUI) on a management workstation (WS). The present invention relates to a control system and a DLL control system for automatic module extraction / update when the server and WS power are turned on.

[0002]

2. Description of the Related Art A conventional DLL is a basic processing unit 2-1 shown in FIG. 2, a DLL task 2-3, and a management table 2-.
2, a DLL task 2-6 in WS2-4, and a management table 2-5.

When the WS 2-4 starts up, the DLL task 2-6 sends the management table 2-to the basic processing device 2-1.
Download the contents of 5 and download the DL of the basic processing device 2-1.
The L tax 2-3 compares the contents of the management tables 2-2 and 2-5, and the DLL tax 2-6 updates the revision of the management table 2-5 after receiving the module.

[0004]

DISCLOSURE OF THE INVENTION The above-mentioned conventional DLL
In the control method of 1. Since a management table is provided for each WS, enormous efforts are required to construct a system with a large number of WS and to set a management table and its table information when adding a WS. 2. Since it is necessary to confirm the revision after the DLL is executed for the number of WSs, it takes time. 3. If the DLL fails, WS has to be restarted again. There are problems such as.

As described above, due to the increase in the number of terminal devices due to downsizing and the like, it takes a great deal of labor and time for the administrator to manually perform the work as usual, and the transfer and update of the module are performed by the administrator. It was extremely troublesome for me.

It is an object of the present invention to provide a graphic user
By utilizing the interface and the mouse, it is possible to reduce the work manually performed by the administrator.

[0007]

According to the DLL control method of the present invention, the transfer information required for the DLL using the GUI is automatically generated from the transfer destination file and the module list file on the management WS. Then, the module registration function to register in the database on the server, the module transfer function to transfer / update the module, the DLL status reference function to refer to the DLL execution status, and the database to refer to the database when the power is turned on , A function of performing module update processing for its own server, and a function of taking out an untransferred module to the own WS by referring to the database of the parent server when the power is turned on and an updating function of the taken out module are provided on the WS. There is.

[0008]

In the conventional DLL, the module information (transfer destination, update date) and the like are manually set for each module. However, by using the control method according to the present invention,
The system administrator can transfer and update modules very easily and in a short time by operating the mouse on the window.

[0009]

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a system to which a DLL control system according to an embodiment of the present invention is applied.

This system has a module registration function 1-
2, module transfer function 1-3, DLL status reference function 1
Management workstation 1-1 including -4 and DL
A database 1-8 for managing L information, a WS extraction command 1-6, a plurality of servers having a module updating function of the own server when the power is turned on, and a database of the parent server 1-5 are referred to and untransferred to the own WS. Module removal
It is composed of WS1 and WS2 under the control of the server, which has an updating function and refers to the parent server when the WS power is turned on and which has a function of taking out and updating the module which has not been transferred to the own WS.

Next, the DL of the present embodiment configured as described above.
The operation of the L control method will be described. First, the module registration function 1-2 uses the data in which the directory of the transfer destination file 3-1 including the item 3-4 in FIG. 3 and the directory of the module list file 3-2 including the item 3-5 match. Generate data 3-3 including items 3-6,
Register in the database. The data to be registered is information only for each server and the subordinate WS.

When the module transfer function 1-3 is executed, the module is transferred to the designated directory by referring to the database 1-8.

Then, the WS extraction command 1 on the server 1-5
By -6, the WS extraction / update function 1-11 on the (WS1) 1-9 and (WS2) 1-10 is activated.

Activated WS extraction / update function 1-11
Refers to the database 1-8 on the parent server 1-5,
The module that has not been transferred to the own WS is retrieved from the server 1-5, and the retrieved module is compared with the item “use start date” in the database 1-8 and the system date, and the system date exceeds the use start date. In this case, the module is updated by executing the "command sequence" in the database 1-8.

Each time the module transfer / update is executed,
The item "DLL status" of the database 1-8 is shown in 6- of FIG.
Rewrite to DLL states 1 to 6-7.

The DLL status reference function 1-4 displays the execution result of module transfer / update on the GUI.

On the state selection screen of FIG. 6, 6-1 to 6-
When one of the DLL states of 7 is clicked with the mouse, the database 1-8 is searched, and a transition is made to the server name list screen 7-1 of FIG. 7 displaying the corresponding server name.

Next, when one server name displayed on the server name list screen 7-1 is clicked with the mouse, the database 1-8 is searched, and the corresponding DLL under the selected server is searched.
The screen transits to the WS name list screen 7-2 which displays a list of WS names in the state.

[W] displayed on the WS name list screen 7-2
When the S name is clicked with the mouse, the database 1-8 is searched, and the list of module names on WS and the module name list screen 7-3 displaying the number of modules are displayed.

Finally, when one of the module names displayed on the module list screen 7-3 is clicked with the mouse, the database 1-8 is searched and the detailed information screen 7-4 for displaying detailed information of the module is displayed. To do.

By clicking "Exit" on the screens 7-1 to 7-4, the sub-menu 7-5 is displayed, and if necessary, the previous screen (screen 7-4 to screen 7-3), FIG. Transition to the state selection screen of.

When the power of the server 1-5 in FIG. 1 is turned on, the module update function 1-7 of the own server refers to the database 1-8 on the own server when the power of the server is turned on to update the corresponding module, The result is the data item "DLL state"
Write to.

In FIG. 1, (WS1) 1-9, (WS2) 1-
When the power of 10 is turned on, the module extraction / update function for the own WS refers to the database 1-8 on the parent server when the WS power is turned on, executes the extraction of the corresponding module, and the result is the data item "DLL state". Write to

Then, referring to the parent server database 1-8, the corresponding module is updated, and the result is written in the data item "DLL state".

[0026]

As described above, according to the present invention, the management W
S, a GUI on the management WS in the DLL control method in the system configured by a plurality of servers and the subordinate WS
Module registration function, module transfer function, D
By providing the LL status reference function, the function of updating the server's own module when the power is turned on on the server, the function of taking out the untransferred module to the own WS when the power is turned on, and the function of updating the taken out module, the DLL is provided. The effect that the pre-processing, execution, and confirmation can be performed in a very short time only with the GUI and the mouse is obtained.

Further, even if the DLL fails, the power is turned on.
At times, the server and WS can do the DLL automatically.

Since the information necessary for updating the module is registered in the database, the module updating is
Since it is automatically performed inside the system, the system administrator has an effect that the time spent on the DLL can be visually minimized and easily.
