How to Check your Exadata Version » Oracle Exadata Patching

Although patching an Oracle Database is a common task for most DBAs, Exadata Patching can be a more intricate process, as it incorporates the complexity of patching a number of components in the Exadata Systems.
Oracle Offers free, Exadata patching to their Exadata customers under Oracle Platinum Services. However, there are many times when patches need to be applied to your Exadata Machine that won’t work on Oracle’s schedule, needing between 8-12 prior notice. 
In a traditional Database Environment, a Database Administrator would use patch GRID_HOME and ORACLE_HOME and patching is done, but in Exadata Patching you must consider the following components.
  •  Exadata Storage Server
  •  Database server
  •  InfiniBand switch
  • Additional components, ex. Ethernet

Patches can be divided in 3 different parts:
