4.3.15.1 ADD EXASCALECLUSTER

This command adds a new Exascale cluster.

Syntax

ADD EXASCALECLUSTER
   NAME = exascaleclustername
   [ VIP = ersvip
     IP = ersip ]

Arguments

• NAME: Specifies the name of the Exascale cluster.
• VIP: Specifies the DNS name for the virtual IP (VIP) interface that provides access to Exascale control services (also known as Exascale RESTful Services or ERS).
• IP: Specifies the IP address for the ERS VIP.

Usage Notes

• The network interface specified by VIP and IP is associated with a highly-available virtual IP (VIP) network interface, which provides a consistent network end point for Exascale control services. The VIP is hosted by one of the Exadata storage servers, which also runs a front-end ERS instance. If the storage server or ERS instance becomes unavailable, then the VIP moves to another server hosting a front-end ERS instance.

  You should define the ERS VIP if possible. The option to define an Exascale cluster without an ERS VIP primarily exists to support Exascale configurations on existing Exadata systems that have no spare IP addresses to support the ERS VIP.
