Procedure documentationConfiguring the SAP Gateway Locate this document in the navigation structure


As with all SAP programs, the SAP Gateway can be controlled by parameters. For example, you can use parameters to set the maximum number of CPI-C connections or the size of memory areas.

The installation of a SAP Gateway for TCP/IP connections within an instance of an SAP system is standard.

The SAP gateway reads the parameters from the SAP profile file (profile directory) like every other process.


You can specify four different types of parameter value. Evaluation corresponds to the following hierarchy of priorities:

  • Priority 1: Command line arguments.

    These are only available for certain parameters, for example instance number.

  • Priority 2: Instance profile

    Each instance has a specific profile. The instance profile is used to set the parameter values of an instance process.

    The file name of an instance profile follows the convention

    <SAP-System><Instanz>, for example, CUAG45.

  • Priority 3: Default profile in the SAP system.

    The values in the default profile DEFAULT.PFL apply to the entire SAP system. All the instances in an SAP system access the default profile. However, if the parameter has already been set in the command line or in an instance profile, a parameter setting in the default profile will not take effect.

  • Priority 4: Default values

    There are pre-set values (defaults) for most parameters. Unless you specify a preferred value, each of these parameters accepts the default system value. Default values can only be pre-set by SAP.

Changes to parameter values only take effect when you restart the processes concerned.

Profile Parameters

The gateway profile parameters are valid in the standard system for the SAP gateway on supported platforms.

You can find a description of the most important gateway profile parameters under Parameterization of the SAP Gateway.

In an SAP system (AS ABAP) you can display all parameters with values by running report RSPFPAR or by starting the gateway monitor (transaction SMGW or choosing   Administration   System Administration   Monitor   System Monitoring   Gateway Monitor  ), and then choosing   Goto   Parameters   Change   or Display. Choose Change Parameter, and you can display the system documenation for any parameter.

You can maintain profile parameter values in the Computing Center Management System (CCMS). Choose   Administration   CCMS   Configuration   Profile Maintenance   or Transaction RZ10.

To display parameter properties and descriptions, use transaction RZ11.
