Using the SAP Gateway Monitor in the SAP System

Use

The Gateway Monitor is used for analyzing and administrating the SAP Gateway in the SAP system.

The initial screen of the gateway monitor shows all the active gateway connections on this instance.

The fields on this screen have the following meaning:

Number	Connection number
LU Name	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. With CPIC connections via TCP/IP, this field describes the host on which the partner program is running or supposed to run.
TP Name	Long transaction program name or the name of the program that was started by the gateway.
User	Name of the user who is currently using the connection
Status	This field indicates the status of the connection: FREE : Connection is not being used INIT : Connection is being initialized INITIALIZED : Connection initialized CONNECT : Setting up connection CONNECTED : Connection set up DISCONNECT : Connection to be closed down DISCONNECTED : Connection closed down
Symbolic (Destination)	The symbolic destination is required when CPIC connections are set up and is a key for the TXCOM and side information tables. These tables manage the required connection parameters. First the system attempts to read unknown parameters from table TXCOM. Afterwards the gateway reads all the parameters not defined in this table from the side information.
Conversa(tion ID)	The conversation ID is a unique number that can be used to identify the connection. By clicking this field, you can display details of the connection.
Prot	This field indicates the protocol agreed with the client: R2PR: R/2 presentation INT : Internal communication EXT : External communication REG : External communication with registered program CPIC: CPI-C communication NE : External communication, not started by gateway
Last Req	Time of last activity
SAP	SAP return code: These return values are defined by SAP; you can display an overview in F1 help. The previous and following syslog messages provide further details on the source of the error. If the syslog messages are not sufficient, the relevant trace files must be analyzed. The return codes are described under Error Analysis.
CPIC	CPI-C return code: The return values of the individual CPI-C functions and their meaning are defined in the "X/Open Developers' Specification - CPI-C". You can display an overview in F1 help. The previous and following syslog messages provide further details on the source of the error. If the syslog messages are not sufficient, the relevant trace files must be analyzed.
