2504600 - Server IP address or hostname changed during live operation

• The IP address or the hostname of the SAP server was changed during the live operation of the system.
• SAP was not stopped before the change was made, nor restarted after the change.
• Some of the RFC destinations start to fail after the IP address was changed.
  One of the commonly affected destinations is the "CALLTP_<operating system>".
• Remote RFC clients fail to logon to the server with a message like:
  

  LOCATION    SAP-Gateway on host [old hostname of SAP server] / sapgwXX
  ERROR       hostname '[old hostname of SAP server]' unknown

• Product independent
• Network Infrastructure
• Client/Server Technology
