Oracle 11g Rel 2: Grid Plug & Play

Grid Plug and play reduces the cost of installing, configuring and managing server nodes by using Grid Naming Service within the cluster to allow each node to perform the below action.

  • Negotiate appropriate network identities for itself.
  • Acquiring additional information from a configuration profile.
  • Configuring and re-configuring itself using profile data, making host names and addresses resolvable on the network.
Grid Plug and Play Domain
Grid Plug and Play domain is a collection of nodes belonging to a single cluster served by the GPnP service.
  • Cluster name: cluster-node01
  • Network name: example.com
  • GPnP domain: cluster-node01.example.com
Each and every node participated in GPnP domain has some common characteristics:
  • Will have at least one routable interface with connectivity outside of the GPnP domain for the public interface. If there are multiple interface then it is required binding to be identified in the GPnP profile.
  • Will have a unique identifier that is unique within the GPnP domain, and it is established through OSD.
  • A personality affected by the GPnP profile, physical characteristics and software image of the node including application that may be running. Below are the characteristics of the node personality includes.
    • Cluster name
    • Network classification (public/private)
    • Storage to be used for ASM and CSS
    • Digital signatures
Usually GPnP profile is stored in XML file and can be found at $Grid_Home/gpnp/profiles/peer/profiles.xml

Hope this will help you out friends, Please feel free to put your comments.

  1. Thank you for the article.
    This was really helpful for me. My main task was to classify online data room providers in the database I worked with. Thanks again for Grid Plug and play.
