Changing the IP address for the EAC Central Server machine

This topic describes how to change the IP address of an EAC Central Server machine, in an environment featuring remote MDEXHost machines, where the AppConfig.xml files use host names rather than IP addresses for the machines.

To change the IP address for an EAC Central Server machine:

  1. Stop the Endeca HTTP service on both the EAC Central Server and remote MDEXHost.
  2. Change the networkaddress.cache.ttl in the java.security file to 0 on both machines. This file is located by default in %ENDECA_ROOT%\j2sdk\jre\lib\security on Windows and $ENDECA_ROOT/j2sdk/jre/lib/security on UNIX.
  3. Change the IP address of the EAC Central Server, making sure that the MDEXHost operating system can resolve the EAC Central Server at the new IP address.
  4. Restart the Endeca HTTP service on both machines.
  5. Optionally, you may go back to the java.security file mentioned in step 2 above, change the networkaddress.cache.ttl back to -1, and restart the Endeca HTTP service on both machines to avoid subsequent DNS spoof attacks.
