Procedure

You can display a list of currently logged on systems by choosing   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 is to run.

    Note Note

    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.

    End of the note.

  • TP Name: Name of the transaction program or the name of the program that was started by the gateway.

  • System Type. The following values are permitted:

    • NORMAL_CLIENT : Normal client (external program)

    • LOCAL_R3: Local SAP System

    • REMOTE_GATEWAY: Connection to remote gateway

    • FROM_REMOTE_GATEWAY: Connection from a remote gateway

    • REGISTER_TP: Registered transaction program

  • Host Name: Name of host client is running on

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

  • Last Request: Time of last activity

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

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

    • Connections with status Connection Pending (handshake while opening the connection) are colored orange

    • 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).

  • Reg. Status: Status of a registered RFC server program. Following statuses are possible:

    • Logged on: The program is logged on, but is not accepting any requests

    • Waiting: The program is waiting for calls from the system

    • Running: The program is processing a request from the system
