In FIG. 1, a client 3 has a manual login request issuing processing unit 31 and sends a manual login request to the host computer 1 to the server 2 by using a user name / password, which is input information from a user, as interface data. Done through

The server 2 has a manual login request relay processing unit 24, relays a manual login request from the client 3, and sends it to the host computer 1. In addition, the host computer 1 has a user session information storage processing unit 23, and when the manual login request ends normally in the host computer 1, waits for the result and stores it in the session information storage unit 28 as user session information.

Further, it has an automatic login request issuance processing unit 25, and automatically performs a login request issuance process based on user session information. The host computer 1 has a login request acceptance determination processing unit 11, processes a login request sent from the client 3 via the server 2, and determines the establishment of a user session. Further, it has a user session information storage processing section 15 and stores the user to be automatically logged in as user session information in the user session information storage section 18. Further, it has a user session state notification processing unit 13 and notifies the server 2 of user session information to be automatically logged in.

The user session is passed from the manual login request issuance processing unit 31 to the login request acceptance determination processing unit 11 via the manual login request relay processing unit 24, and is established after being authenticated there. In this state, when a user session is released without a request from the user, the information of the target user session is stored in the user session information storage unit 18 by the user session information storage processing unit 15, and the automatic recovery is performed. Handle as a target user session.

The user session status confirmation processing unit 2
In step 6, the user session information to be automatically recovered is received from the user session state notification processing unit 13 and is recognized by the server 2. As a result, the necessity of the user state matching is recognized, an automatic login request is issued from the session automatic login request issuance processing unit 25, and the automatic recovery of the user session becomes possible.

In FIG. 2, the server 2 has a user session state confirmation processing unit 26, and performs a user session state confirmation request to the host computer 1 and determines a response to the request. Further, it has a failure detection processing unit 21 and detects the occurrence of a communication failure with the host computer 1.
Further, it has a failure recovery detection processing unit 27, and detects failure recovery with the host computer 1.

The host computer 1 has a failure detection processing unit 14 and detects the occurrence of its own failure and the occurrence of a communication failure with the server 2. It also has a user session release processing unit 16 to release a user session when a failure occurs.

The host computer 1 uses its own failure or the host computer 1
An error between the server and the server 2 is detected, and a user session release process is performed. As a result, inconsistency in the user state occurs, and information on the target user session is held prior to the inconsistency, whereby inconsistency can be detected with the server 2. With this configuration, even if the user session is lost and the user status becomes inconsistent,
Automatic recovery of the user session can be performed by the automatic recovery means.

In FIG. 2, the host computer 1
An automatic recovery waiting state monitoring processing unit 17 is provided. Then, when a session is released without a request from the user, automatic recovery is performed through the state matching processing. The host computer 1 monitors the state in the automatic recovery waiting state monitoring processing unit 17. . Until the automatic recovery processing is performed, the automatic recovery wait state is set, and during that time, the server 2 and the client 3 maintain the state at the time of the user session establishment, and immediately after the automatic recovery is completed, the state before the occurrence of the session inconsistency. It is possible to operate as it is.

In FIG. 2, the server 2 has a user session information release processing unit 22 and automatically releases a user session as needed. When the server 2 enters the automatic recovery waiting state of the user session, the server 2 performs the user session state confirmation processing in the user session state confirmation processing unit 26 and acquires the session state information from the host computer 1, but detects that this failed. As a result, it is determined that the automatic recovery is impossible, the user session information of the user is discarded, and the automatic logout process is performed.
Thereby, when the automatic recovery is not performed, the user sessions of the server and the client can be automatically released.

In FIG. 2, the client 3 has a connection destination server switching unit 33. Therefore, the connection destination server is switched as required. When the host computer 1 and the server 2 are in a session automatic recovery waiting state, the client 3 can switch the connection of the server 2 by the connection destination server switching processing unit 33. By using the manual login request issuance processing unit 31 from this state, login processing from a normal user can be performed. In other words, even when waiting for automatic recovery, the connection destination of the client 3 can be switched to another server, and manual login can be enabled.

In the figure, reference numeral 40 denotes a common header, which is an agreement between the host and the server, and contains control information indicating what kind of data this data is. 41 is a terminal name, 42 is database collation information, 43 is the name of a user who logs in, 44 is a password for logging in, 45 is a server ID (SV ID) and a client ID (CL ID).
It is. 46 is a request ID (Req ID),
“1” is manual login and “2” is automatic login.

In FIG. 3, in the normal manual login request issuing process, all the interface data including the shaded portion is required. Also, in the automatic login request issuing process, interface data excluding the shaded portion is required. In the manual log-in process, all the interface data including the shaded portion in the figure is required.

On the other hand, in the automatic login request processing, since the session information to be automatically recovered is managed in the host computer 1 in advance, the security authentication is performed only by the user name and the Req ID excluding the hatched portion. It becomes possible. As a result, automatic login can be performed without storing password data, which is confidential information, in the system. That is, when the session is released, the user session can be automatically recovered without holding the password of the user.

FIG. 4 is a diagram showing a user session automatic recovery processing sequence. When the user performs manual login from the client, the login request is notified to the host computer via the server. The host computer reads out the session information of the user A and sends it to the server. The server gives the received session information of the user A to the user via the client.

In this state, it is assumed that a communication error or an error has occurred in the host computer. At this time, the server and the client hold the read session information of the user A. At this time, the host computer releases the user session, and the session information of the user A is released. The client and server are in a state of waiting for automatic recovery of the user session.

Here, when communication is restored between the server and the host computer, the server issues user information to the host computer. Upon receiving this signal, the host computer acquires the session state of the user A, and issues an automatic recovery processing request to the server.

In response to this, the session information of the user A held in the server is automatically logged in to the host computer, the information of the user A is read from the session information storage section of the host computer, and notified to the server. As described above, according to the present invention, even when an abnormality occurs in the host computer, the matching can be achieved by transferring the session information held in the server to the host computer.
