Que) Is it possible to change all IP on Exalytics box or does the new installation required? If change in IP is possible, is it supportable?
It is not officially supported to change the IP address or hostname
of an Exalytics machine. The application installation process creates
all the configuration files to match an environment. Changing the host
name or IP address will likely break the functionality, and there are a
great number of locations this could be specified. It is dangerous to
correct them manually. Additionally, if the network was not setup
properly, within Enterprise Manger you may see references to IP
addresses rather than the hostname.
If you so chose to change the IP on an Exalytics server we recommend that:
- Check your networking configuration for IP/hostname mappings is correct in any DNS servers and /etc/hosts files
- Shutdown all the OBIEE processes
- Change the IP address only (note that changing the hostname is not supported)
- Check that the new IP address resolves to the correct hostname
- Startup all the OBIEE processes
- Check it works
The procedure should be carried out by someone familiar with network configuration.
Additionally the IP change in Exalytics may or may not have any impact.If all the applications are installed and configured with Host name as the target entry for application then it will have no impact.If the applications are installed and configured to IP of the Exalytics unit then change in IP will require change in IP all places and restart of services.
