Oracle Fleet Patching and Provisioning (Oracle FPP) architecture consists of an Oracle FPP Server and any number of Oracle FPP Clients.

Oracle recommends deploying the Oracle FPP Server in a multi-node cluster so that it is highly available. Oracle FPP Server supports single-node deployment, but it is not recommended.

The Oracle FPP Server cluster is a repository for all data, of which there are primarily two types:

• Gold images
• Metadata related to users, roles, permissions, and identities

The Oracle FPP Server acts as a central server for provisioning Oracle Database homes, Oracle Grid Infrastructure homes, and other application software homes, making them available to the cluster hosting the Oracle FPP Server and to the Oracle FPP Client clusters, and rhpclient-less targets.

Users operate on the Oracle FPP Server or Oracle FPP Client to request deployment of Oracle homes or to query gold images. When a user makes a request for an Oracle home, specifying a gold image, the Oracle FPP Client communicates with the Oracle FPP Server to pass on the request. The Oracle FPP Server processes the request by taking appropriate action to instantiate a copy of the gold image, and to make it available to the Oracle FPP Client cluster using available technologies such as Oracle Advanced Cluster File System (Oracle ACFS) and local file systems.

• Oracle Fleet Patching and Provisioning Server
  The Oracle Fleet Patching and Provisioning (Oracle FPP) Server is a highly available software provisioning system that uses Oracle Automatic Storage Management (Oracle ASM), Oracle Advanced Cluster File System (Oracle ACFS), Grid Naming Service (GNS), and other components.
• Targets of Oracle Fleet Patching and Provisioning
  Computers of which Oracle Fleet Patching and Provisioning (Oracle FPP) is aware are known as rhpclient-less targets, which do not have the rhpclient component enabled.
• Oracle Fleet Patching and Provisioning Clients and Targets
  The Oracle Fleet Patching and Provisioning (Oracle FPP) Client is part of Oracle Clusterware. Users operate on an Oracle FPP Client to perform tasks such as requesting deployment of Oracle homes and listing available gold images.
• Images of Oracle Fleet Patching and Provisioning
  You can easily copy an image of an Oracle home to a new host on a new file system to serve as an active usable Oracle home.
• Working Copies of Oracle Fleet Patching and Provisioning
  Working copy is a copy of the gold image that you use to provision the software on an Oracle Fleet Patching and Provisioning (Oracle FPP) Client or an rhpclient-less target.
