Function documentationSAP Gateway Monitor

 

The Gateway Monitor (transaction SMGW) 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:

Column (long/short name)

Meaning

Connection Number/Number

Number to identify the connection

Long Logical Unit Name / Local LU Name / LU Name

Host on which the local partner program is running or is to run.

Long Transaction Program Name / Local TP Name / TP Name

Long transaction program name, or the name of the local program that was started by the gateway.

If it is an ABAP program (protocol: internal communication) you can see the service (port) of the local gateway here.

Long Logical Unit Name / Remote LU Name / LU Name

Host on which the remote partner program is running or is to run.

Status

This field indicates the status of the connection: It can have the following values:

  • unused: Connection is not being used

  • Initial: Connection is being initialized

  • Initializing: Connection initialized

  • Connecting: Connection is being opened

  • Connected: Connection is made

  • Is being interrupted: Connection to be closed down

  • Interrupted: Connection closed down

Symbolic Destination / SymbDest

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.

Protocol / Prot

This field indicates the protocol agreed with the client: The following values are permitted:

  • Internal Communication: Communication partner is an ABAP program (the same or a different SAP system)

  • External Communication: Communication partner is an external program

  • Registered Communication: External communication with registered program

Last Request / Last Activity

Time of last activity

SAP Error/ SAPRC

The return codes are described under Error Analysis.
