DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to labor saving of operation management of a computer network system and security of an application program.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional terminal connection management (part 1).
It is. 2, 1a is a host computer, 2a, 2b, 2c... Are terminal devices, 3a, 3b,
.. Are the users of the host computer. The terminal devices 2a, 2b, 2c...
Channel or via-line channel.

Each of the terminal devices 2a, 2b, 2c,... Has a terminal identification code T1, T2, T3,. Similarly, the user of the host computer 1a also has the personal identification code P1, P2, P3.
... so that they do not overlap.

In the following, an identification number is referred to as ID (IDe).
). In the host computer 1a, application programs A, B, C,.
... and an OS (operating system) are running.

[0005] A part of the OS has a terminal ID registration table or a personal ID registration table. The terminal ID registration table stores application programs A, B, C,.
.. Irrespective of..., The ID of a terminal that can access (use) the host computer 1a is registered.
Alternatively, in the personal ID registration table, IDs of individuals who may access (use) the host computer 1a irrespective of the application programs A, B, C,... Are registered.

Naturally, when a terminal or an individual not registered in the terminal ID registration table or the personal ID registration table accesses the host computer 1a, the OS refers to those tables and
Notify the terminal that access is not possible.

In the above-described computer network system, for example, an application program A
Is an online sales management program, and the terminal device 2a
(ID “T1”) makes this online sales management program available for 24 hours, and the terminals 2b, 2c... (I
D is “T2, T3,...”) As a terminal device (a terminal for inputting data of an online sales management program) of each local branch office, from 9:00 AM to 9:00 PM on Monday to Friday.
5:00 can be used.

In such a case, an online sales management program is started every day at 9:00 am using the operation management terminal device 2a (ID is “T1”), and every day at 5:00 am
0 (actually 5:30 or 18:
00) The operation of the online sales management program is stopped. Then, the online sales management program is started again, and some processing is performed using the operation management terminal device 2a.

When the operation is temporarily stopped at 5:00 pm and then restarted, only the operation management terminal 2a can use the online sales management program, and the other general terminals 2b, 2c. You can't use that online sales management program.

[0010] In order to perform such operations without trouble, the number of terminals that can be connected after the restart of the program is reduced, and in the above example, the number of terminals is reduced to “1”, and PM5: 0
After 0, only the operation management terminal device 2a can use the online sales management program.

FIG. 8 shows a conventional terminal connection management (part 2). The method of FIG. 8 differs from the method of FIG. 7 in that each application program A, B, C,... Registers the ID of a terminal or an individual who may access the application program.

For example, in the terminal ID registration table of the application program A, the terminal ID “T1, T2, T
3 "is registered, and the personal ID is registered in the personal ID registration table.
“P1, P2, P3” are registered. In this case, if there is access from a terminal whose terminal ID is other than “T1, T2, T3”, the application program A notifies the terminal that access is not possible.

However, in this case, it is impossible to change the connectable terminal depending on the time zone. The application program A is an online sales management program, the application program B is a technical calculation program, and the terminal 2
a and 2c can access both of the above application programs, terminal 2b can access the online sales management program, terminal 2d can access the technical calculation program, and has access to the online sales management program. Impossible.

In the case of this method, a certain degree of security can be ensured. As described above,
The connection between the terminal and the host computer is managed.

[0015]

In the conventional terminal connection management method, an online application is switched on a specific day of the week or on a specific day such as switching of an application program in a daily time zone, weekend processing, monthly processing, year-end processing, and year-end processing. When running restriction of the program (priority running of the batch processing program) is necessary, it is difficult to manage the connection of the terminal, and when a certain batch processing program is processing a certain database, the database is an online application program. There was a security issue of being updated.

Alternatively, if there is a terminal that can access a certain application program for 24 hours and a terminal that can be accessed during a specific time period, for example, between 9:00 AM and 5:00 PM, once at 5:00 PM There is a problem of inefficiency in that the running of the application program is stopped, and then the application program is started again, the number of terminals is limited, and the terminal is accessible for 24 hours to access the application program.

In view of the above, an object of the present invention is to provide means for checking a terminal which can be connected to each application program on a daily time zone, a specific day of the week, and a specific day.

[0018]

The above object is achieved by a terminal connection management method configured as described below. FIG. 1 is a diagram illustrating the principle of the present invention.

A terminal connection management device that allows access from the device terminal connected to the host computer via the transmission line 4 to the host computer in terms of time, wherein the personal ID or the terminal permits access on a date basis. I
A specific day table in which D is associated with a time zone in which access is permitted, a day table in which personal IDs or terminal IDs in which access is permitted in units of days of the week are associated with time zones in which access is permitted, If it is registered in the specific day table, access control is performed using the specific day table. If the date of the access is not registered in the specific day table, access control is performed using the day of the week table. It is configured to have a connection management function unit.

[0020]

That is, in the present invention, a time zone table 10, a day of the week table 11, or a specific day table 12 is provided for each processing function unit 6, and the terminal ID or personal ID connectable to the table is registered. When the terminal accesses the processing function unit 6 of the host computer 1, the time, day of the week, and date of the access are read from the calendar table of the OS or the day of the week is calculated from the date. By checking in the tables 10, 11 and 12 whether the terminal ID or the personal ID is registered in the table and is accessible at the access time, the processing function unit 6 can be stopped or restarted. It is not necessary to perform such operations, and unauthorized access by persons other than those involved can also be prevented.

[0021]

FIG. 2 shows an embodiment of the present invention, and FIG.
FIG. 1 is a system configuration diagram to which the present invention is applied.

In FIG. 2, A is an application program A, 10 is a time zone table, 11 is a day of the week table, and 12 is a specific day table. These tables 10, 11, and 12 also exist in other application programs.

In FIG. 3, 1 is a host computer, 2a, 2b, 2c and 2i are terminal devices, 3a and 3
.. b, 3c, 3j are individuals who use certain application programs of the host computer 1 using the terminal devices 2a, 2b,.

Each terminal is connected to a channel of the host computer 1 or to a channel via a communication control device. In addition, each terminal device 2a, 2
.. b are identification codes (ID) T1, T2, T3, respectively.
, And each individual has an identification code (ID) P
1, P2, P3,...

These terminal IDs and / or personal IDs correspond to the time zone table 10 or the day of the week table 1
1 or the specific date table 12. Time zone table 1 of application program A in FIG.
0 indicates that it is possible to use the application program A by online connection of the terminal device whose terminal ID is T2, T3,... During 9:00 AM to 5:00 PM. The terminal device having the ID of T1 indicates that the application program A can be used for online connection for 24 hours.

Similarly, in the day of the week table 11, Monday through
During Thursday AM 9:00 to PM 5:00, it is indicated that the application program A can be used in the online connection of the terminal device whose terminal ID is T2, T3,. The terminal device T1 indicates that the application program A can be used for online connection for 24 hours.

On Friday, AM 9:00 to PM
During 3:00, it is indicated that it is possible to use the application program A by online connection of the terminal device with the terminal ID T2, T3,..., And the terminal device with the terminal ID T1 is This indicates that the application program A can be used for online connection for 24 hours.

Further, on Saturday, it is shown that only the terminal 2a whose terminal ID is T1 can use the application program A by online connection during AM 9:00 to PM 3:00.

Similarly, in the specific day table 12, March 3
On the 0th and the 30th of September, as in the case of Friday in the above-mentioned day-of-the-week table, during the period of 9:00 AM to 3:00 PM, the online connection of the terminal having the terminal ID of T2, T3,. A indicates that it is possible to use application program A, and indicates that a terminal having a terminal ID of T1 can use application program A by online connection for 24 hours.

By providing at least one of the time zone table 10, the day of the week table 11, and the specific day table 12, when a certain terminal device 2i (ID is Ti) accesses the application program A at a certain date and time, Whether or not to allow the access is determined as follows.

FIG. 4 is a calendar table of the OS.
The calendar table of this OS contains "year, month, day, day,
Hours, minutes, seconds "data. FIG. 5 is a flowchart (1) of the terminal connection check, and FIG. 6 is a flowchart (2) of the terminal connection check.

This will be described below with reference to FIGS. . When an application program A is accessed from a certain terminal device 2i, the ID “T
i "is read, and the contents of the calendar table 13 of the OS are read. (Processing step 101). If there is no information on “day of the week” in the calendar table 13 of the OS, the “day of the week” is calculated as follows. (Processing steps 102 to 103) (A). Since January 1 of the year 1 (or 1900) is "Monday", one year is 365 days and the year 1
The total date from January 1 of the year (or 1900) is calculated.

(A). In (a), the year that is an integral multiple of “4” is “leap year” (one year is 366 days) (for example, 19 years).
The year that is an integral multiple of “100” is a normal year (1 year is 3 years).
65 days) (for example, 1900), and a year that is an integral multiple of “400” (for example, 2000) is calculated as a “leap year”.

(B). 1 AD (or 1900) 1
If you find the total date from the first day of the month, divide it by "7". If the remainder is "0", "Sunday"; if the remainder is "1", "Monday"; and, according to the remainder value, "Tuesday to Saturday".

[0036] It is confirmed whether the specific day table 12 exists. (Processing step 104) If the specific day table 12 exists, it is checked whether the information of the calendar table 13 of the OS and the terminal ID information correspond to the specific day of the specific day table 12.
(Processing step 105) If it does not correspond to the specific date, the process proceeds to the next process.

If the date falls on a specific day, it is checked whether the access time falls within the accessible time zone of the specific day. (Processing step 115) If the access time falls within the accessible time zone of the specific day, the process proceeds to the next step. If the access time is not within the accessible time zone of the specific day,
Proceed to.

[0038] It is checked whether the ID of the terminal that has made the access is registered. If the ID of the terminal is registered, the terminal is permitted to access the application program thereafter. However, also in this case, the time is always monitored, and if it is out of time, the process proceeds to the next. (Processing step 111). The terminal 2i is notified of "out of time" and access to the application program of the terminal 2i thereafter is not permitted. (Processing step 112). It notifies the terminal that "this terminal ID is not registered." And does not permit the terminal 2i to access the application program thereafter. (Processing step 113). It is confirmed whether the day of the week table 11 exists.
(Processing step 106) If the day of the week table 11 exists, it is confirmed whether or not the accessed day of the week exists in the day of the week table 11. (Processing step 107) If the accessed day is the day of the week table 1
If the access time is 1, it is checked whether the access time falls within the accessible time zone of the day of the week when the access was made. If it is within the accessible time zone, proceed to. If not, proceed to. (Processing step 116) If the day of the week table 11 does not exist, the process proceeds to the next step.

[0039] It is checked whether the time zone table 10 exists. (Processing step 108) If the time zone table 10 exists, it is checked whether or not the access time falls within the accessible time zone of the time zone table 10. If it is within the accessible time zone, proceed to. If not, proceed to. (Processing step 109) If the time zone table 10 does not exist, the processing is performed by the conventional technique. (Processing step 114) As described above, it is possible to control the online connection of the terminal to the host computer.
