The Oracle Fleet Patching and Provisioning Server provides an efficient and secure platform for patching and upgrading Oracle Database.

• Patching Oracle Database
  To patch an Oracle database, you move the database home to a new home, which includes the patches you want to implement.
• Patching Oracle Data Guard Database
  Starting with Oracle Grid Infrastructure 23ai, Oracle FPP enables you to automatically patch Oracle Data Guard standby databases before patching their primary databases.
• Upgrading Oracle Database
  Fleet Patching and Provisioning provides two options for upgrading Oracle Database. Both options are performed with a single command.
• Zero-Downtime Upgrade
  Using Oracle Fleet Patching and Provisioning, which automates and orchestrates database upgrades, you can upgrade an Oracle RAC or Oracle RAC One Node database with no disruption in service.
