Introduction One of the key features of the ODA (Oracle Database Appliance) is the ability to patch the entire stack every three months, the goal being to keep all the components up-to-date.

Why ODA patching can eventually be…

Or simply because you need to change the configuration (for example network configuration) and you want to make things clean, and be sure that future patches…
