Prepare DNS

You must prepare DNS before installing SuperCluster M8 or SuperCluster M7. Installation and the initial configuration cannot proceed until these tasks are finished.


Note -  DNS is not configured on SuperCluster M8 or SuperCluster M7 systems until after initial configuration.
  1. Provide the necessary information in these documents:
    • Oracle SuperCluster M8 and SuperCluster M7 Site Checklists

    • Oracle SuperCluster M8 and SuperCluster M7 Configuration Worksheets

  2. Use the host names and IP addresses specified in the completed configuration worksheets document to create and register DNS addresses for SuperCluster M8 and SuperCluster M7 systems.

    You must register all public addresses, SCAN addresses, and VIP addresses in DNS prior to installation.


    Note -  The configuration worksheets document defines the SCAN as a single name with three IP addresses on the client access network.
  3. Configure all addresses registered in DNS for both forward resolution and reverse resolution.

    Reverse resolution must be forward confirmed (forward-confirmed reverse DNS), such that both the forward and reverse DNS entries match each other.

    The SCAN name to the three SCAN addresses must be configured in DNS for round-trip resolution.
