Displaying Clients Currently Logged On

You can display a list of currently logged on systems via Goto ® Logged on systems .

The following values are displayed for each system that is logged on:

·        LU Name: With CPIC connections via TCP/IP, this field describes the host on which the partner program is running or supposed to run.

The term "logical unit" is a term borrowed from SNA and describes a logical node in an SNA network. The remote partner program is intended to run on this node.

·        TP Name: Name of the transaction program or the name of the program started by the gateway.

·        System Type. The following values are permitted:

Ў        NORMAL_CLIENT : Normal client, external program     

Ў        LOCAL_R3: Local SAP system                     

Ў        REMOTE_GATEWAY: Connection to a remote gateway       

Ў        FROM_REMOTE_GATEWAY: Connection from a remote gateway

Ў        REGISTER_TP: Registered transaction program      

·        Host Name: Name of the host on which the client is running.

·        Host Address: All TCP/IP names of the host. If there are several network cards then there may be several entries here. Usually 5 alternative host names are supported.

·        Last: Time of last activity

·        Status: Connection status to a client or another gateway at TCP/IP level. The default value is CONNECTED.

In the following cases connections are highlighted in color in the gateway monitor.

Ў        Connections with status PENDING (handshake while opening the connection) are colored orange

Ў        If the data packets could not be fully written in the network connections, the connection is colored green. If this status lasts for a while, it indicates network problems, or the partner program cannot read any data from the network, because it is busy with other tasks that take time (for example, BRBACKUP).
