In these notes replace [MIDASBASE] with the base of your software installation (default is /MIDAS)

• Server
  The file [MIDASBASE]/TclHttpd/Linux/TclHttpd-server is a shell script which starts tclsh with the script [MIDASBASE]/TclHttpd/bin/httpd-Server.tcl. During startup the file [MIDASBASE]/config/TclHttpd/[SystemName]/startup.tcl is searched for where [SystemName] can be the result of the command uname -n; localhost or omitted. This startup script loads the system specific services required.
  Two options are supported.
• The first is the case where the spectrum source is within a data acquisition system. The following would load the implementation of the Spectrum Service for this case.

     package require SpectrumServer
  

• Also define within the shell script used to launch the data acquisition system the environment variable MIDAS_MEMSAS_PORT by adding

     MIDAS_MEMSAS_PORT=0
     export MIDAS_MEMSAS_PORT
  

  Also define the data acquisition systems by adding

  namespace eval DataAcquisition {
       variable ACQSERVERS; set ACQSERVERS [list Host1 Host2 .....]
  }
  

  into the Tcl script (/MIDAS/config/TclHttpd) used to launch the Httpd server within the data acquisition system (this may already be present).
• The second is the case where the spectrum source is local (disc based). The following would load the implementation of the Spectrum Service for this case.

     package require DiscSasServer
  

• Httpd
  From a Web Browser contact the URL http://[SystemName]:8015. This returns a page containing the WSDL file descriptions of the services available and a menu of available services.
  The URL http://[SystemName]:8015/Spectrum will directly enter the service.
