Description

Description: TECHNICAL FIELD The present invention relates to a logon function when a plurality of hosts are used from a workstation in a packet switching network.

2. Description of the Related Art Conventionally, when a plurality of hosts are used from a workstation, logon information for connecting to each host must be registered in the workstation.

This logon information is set in the work menu of the workstation as a parameter at the time of starting the program.

Therefore, when the user uses the host,
In consideration of which host the iD is registered on, the target host was selected from the work menu of the workstation and executed.

For this reason, if the environment such as the user iD changes due to the addition or removal of the host, the logon information is added or updated for all the workstations, and the changed user is I was informed that.

[Problem to be Solved by the Invention] In the conventional logon function described above, when there are a plurality of hosts that may be connected, logon information for each host must be registered in a workstation. Then, there is a disadvantage that the user himself / herself must use logon information in consideration of the target host to be connected.

In addition, when a host is added or removed, logon information for connecting to the host must be registered and updated for all workstations. For this reason, there is a disadvantage that the registration / update work requires a lot of time.

[Means for Solving the Problems] In a network system including a plurality of hosts and a plurality of workstations connected to the plurality of hosts, an automatic logon host selection method according to the present invention comprises the steps of: Host user information file for registering user information including identifiers of users who can use, and other host user information for registering correspondence between identifiers of other hosts and identifiers of users who can use the same When a file and a logon request by a user are received from any of the plurality of workstations, if the user information of the user is registered in the host user information file, the logon is permitted. If the user information of the user is not registered in the own host user information file, the other host user information file is not registered. A log-on reception control unit that obtains the identifier of the other host available to the user from the file and returns the identifier to the workstation, wherein each of the plurality of workstations is connected to any of the plurality of hosts. A session switching control unit that switches a connection to the host when a logon request is made and an identifier of any of the hosts is returned from any of the plurality of hosts.

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

<Overall Configuration> FIG. 1 is an overall configuration diagram of the automatic logon host selection method of the present invention.

As shown in this figure, in the automatic logon host selection method, an own host user environment file 1-1 for registering the environment of the user in the own host, and another host user for registering the logon information of the user of the other host A user information transmission control unit 1 that transmits user information registered in the information file 1-2 and the own host user environment file 1-1 to another host;
3. User information reception control section 1-4 which receives user information sent from another host and registers it in other host user information file 1-2, other host user information file 1-2
User information retrieval control unit 1-5 for retrieving logon information of another host in which a user is registered from the user information registered in the user, accepts logon from the workstation, and sends the retrieved logon information to the workstation. The logon reception control unit 1-6 to be returned, the own host logon information file 2-1 for registering logon information for connecting to the own host, and the own host based on the logon information registered in the own host logon information file 2-1. A session opening control unit 2-2 for opening a session to the host, and a session switching control unit 2-3 for switching a session from the host to another host based on logon information sent from the host.

<Operation> Next, the operation of the present invention will be described.

The user can use the workstation keyboard
When an iD is input and a logon request is made, first, the session establishment control unit 2-2 reads logon information from the own host logon information file 2-1 and establishes a session with the own host. A logon request is made to -6. The information shown in FIG. 4 is registered in the own host logon information file 2-1 in advance. At the time of a logon request, the user ID is notified to the logon reception control unit 1-6.

The logon acceptance control unit 1-6 stores the user iD making the logon request in the own host user environment file 1
Search from -1. Local host user environment file 1-1
If the user iD making the logon request exists in the host user environment file 1-1 in which the information shown in FIG. 2 is registered in advance, the session opening control unit 2 -2 is notified of a signal permitting logon. If the user iD does not exist, the user iD is notified to the user iD search control unit 1-5, and a search request for another host in which the user iD is registered is made.

The user information search control unit 1-5 searches the other host user information file 1-2 for logon information of another host in which the user iD is registered, and the logon reception control unit 1
Return to -6. In the other host user information file 1-2, the user information reception control section 1-4 always receives the user information as shown in FIG. 3 transmitted from the other host, and automatically registers and updates the user information. Perform Also, regarding the user information of the own host, the user information transmission control unit 1-3 reads the user information from the own host user information file 1-1, and
Automatically send to other hosts at fixed time intervals.

Upon receiving the logon information of the other host, the logon acceptance control unit 1-6 notifies the session opening control unit 2-2 of a signal indicating that logon is disabled, and at the same time, the user iD who has made the logon request is registered. Returns the logon information of another host that is

When the session opening control unit 2-2 receives a logon permission signal from the logon reception control unit 1-6, the session establishment control unit 2-2 continuously makes a processing request to its own host. When the logon disable signal and the logon information of the other host in which the user iD who made the logon request is registered are received, the session switching control unit 2-
3 is notified of the logon information, and makes a session switching request to another host.

The session switching control unit 2-3 disconnects the session with the host, and issues a session opening / logon request to another host based on the logon information received from the session opening control unit 2-2.

[Effect of the Invention] As described above, the present invention has an effect that the user does not need to be conscious of the target host to be connected by automatically selecting the logon host.

Also, by having user information in the host and automatically transferring this information between the host and the host, or searching for a host in which the user is registered from this information and switching to the target host, The logon information for connecting to one host may be registered in the workstation. Thus, there is an effect that the trouble of registering / updating the logon information in the workstation, such as when a host is added or removed, can be omitted.
