Procedure documentationStarting the SAP Web Dispatcher with the Bootstrap Option Locate this document in the navigation structure

 

The bootstrap option is used to start the SAP Web Dispatcher without the profile file. This file is then created automatically.

Procedure

  1. In the command field enter

    sapwebdisp -bootstrap

  2. Enter message server details required by the bootstrap to create the profile. Before the profile is created, the message server details are checked. If necessary you can correct the data.

    Example Example

    Host Name of Message Server (rdisp/mshost): <sid>main

    HTTP Port of Message Server (ms/http_port): sapms<SID>

    Checking connection to message server...

    ERROR: No data from msg_server received -

    Please check that sapmsSID is the HTTP port and not the native message server port

    Do you want to continue with these settings? n

    Host Name of Message Server (rdisp/mshost): <sid>main

    HTTP Port of Message Server (ms/http_port): 8081

    Checking connection to message server...OK

    In this example an incorrect HTTP port of the message server was entered and then corrected.

    End of the example.
  3. Specify the scenario where you want the Web Dispatcher to run: with a small (s), medium (m) (default), or a large (l) system. The parameters are preconfigured accordingly. The number of sockets in the system are also checked.

    Example Example

    HTTP Port Number for SAP Web Dispatcher: 8855

    Create configuration for s(mall), m(edium), l(arge) system (default: medium): l

    WARNING: Maximum number of sockets supported on this system: 1021

    Please check the operating system configuration

    Here the system is warning you because the operating system only supports 1021 sockets and this is not enough for a large installation.

    End of the example.
  4. Unpack the files for the Web administration as described in Operation of the SAP Web Dispatcher Setting Up the Web Administration Interface.

Result

The bootstrap carries out the following steps:

  1. Generates the profile sapwebdisp.pfl (if it does not already exist)

  2. Creates a user for the Web administration in file icmauth.txt (if it does not already exist) and an eight character random password.

    Example Example

    The output might look like this:

    Authentication file "icmauth.txt" generated

    Web Administration user is "icmadm" with password "RdUAs27F"

    Restart sapwebdisp with profile: sapwebdisp.pfl

    sapwebdisp started with new pid 20435

    End of the example.
  3. Starts the SAP Web Dispatcher with the generated profile

SAP Web Dispatcher is running.

You can now use the Web Administration Interface to monitor and manage the Web Dispatcher.

Parameter Settings Dependent on System Size

Depending on which system size you have chosen (s, m or l), different parameter values are written to the profile file. The table below contains these different values.
