This mechanism is different from SAPLOCALHOST and SAPLOCALHOSTFULL
since ICM allows HTTP Server Aliasing via icm/server_port_<nn>
settings. During startup, icman reads its configuration and propagates it
to the SAP Message Server or the SAP Web Dispatcher Server. These
servers then act as the physical point of access for HTTP requests. They
classify requests and send HTTP redirects to the client in order to
connect them to the required ICM Instance.
This only works properly if the bound ICM instances propagate virtual
IP addresses. Therefore a parameter
icm/host_name_full=<relocatible_ip>
needs to be set within the Instance Profile of the Application Server.
Double-check the settings with report RSBB_URL_PREFIX_GET or review
the parameters within the SMMS transaction.
IS1200 Installation Step:
If you cluster ci, configure the frontend PCs to attach to <relocci>. Most
of the time, this can be achieved by distributing a new saplogon.ini file
to the windows directory.
