Changing IP addresses on Exadata Database Machine (Doc ID 1317159.1)

Last updated on MAY 24, 2021

Applies to:

Oracle Exadata Hardware - Version 11.2.0.1 and later
Information in this document applies to any platform.

Goal

The procedure in this document supports the changing of IP addresses on an Oracle Exadata Database Machine system. The most common use case for this procedure is when a system is moved, so this document was written with that case in mind. Importantly, system hostnames and domain name changes are not handled by this procedure.

It will be more reliable to make these changes using the ipconf and ipconf.pl utilities.  For Compute nodes use:

/opt/oracle.cellos/ipconf.pl

For Storage Nodes use:

/opt/oracle.cellos/ipconf

These utilities make modifications to all pertinent system and Exadata configuration files.  Though making these changes manually is supported it is highly recommended to use these utilities instead.  They will always be up to date as far as what modifications need to be made.  For usage of these utilities, refer to:

System Software User's Guide for Exadata Database Machine
Chapter 5 Maintaining Oracle Exadata System Software
5.2 Using the ipconf Utility
