1. Introduction
NOTE: This RAC Guide is not meant to replace or supplant the Oracle Documentation set, but rather, it is
meant as a supplement to the same. It is imperative that the Oracle Documentation be read, understood, and
referenced to provide answers to any questions that may not be clearly addressed by this Guide.
1.1. Overview of new concepts in 11gR2 Grid Infrastructure
1.1.1. SCAN
The single client access name (SCAN) is the address used by all clients connecting to the cluster. The SCAN
name is a domain name registered to three IP addresses, either in the domain name service (DNS) or the Grid
Naming Service (GNS). The SCAN name eliminates the need to change clients when nodes are added to or
removed from the cluster. Clients using SCAN names can also access the cluster using EZCONNECT.
The Single Client Access Name (SCAN) is a domain name that resolves to all the addresses allocated
for the SCAN name. Allocate three addresses to the SCAN name. During Oracle grid infrastructure
installation, listeners are created for each of the SCAN addresses, and Oracle grid infrastructure
controls which server responds to a SCAN address request. Provide three IP addresses in the DNS to
use for SCAN name mapping. This ensures high availability.
The SCAN addresses need to be on the same subnet as the VIP addresses for nodes in the cluster.
The SCAN domain name must be unique within your corporate network.
1.1.2. GNS
In the past, the host and VIP names and addresses were defined in the DNS or locally in a hosts file. GNS can
simplify this setup by using DHCP. To use GNS, DHCP must be configured in the subdomain in which the
cluster resides.
1.1.3. OCR and Voting Disk on ASM storage
The ability to use ASM diskgroups for the storage of Clusterware OCR and Voting disks is a new feature in
the Oracle Database 11g Release 2 Grid Infrastructure. If you choose this option and ASM is not yet
configured, OUI launches ASM configuration assistant to configure ASM and a diskgroup.
1.1.4. Intelligent Platform Management interface (IPMI)
Intelligent Platform Management Interface (IPMI) provides a set of common interfaces to computer hardware
and firmware that administrators can use to monitor system health and manage the system.
With Oracle Database 11g Release 2, Oracle Clusterware can integrate IPMI to provide failure isolation
support and to ensure cluster integrity. You must have the following hardware and software configured to
enable cluster nodes to be managed with IPMI:
Each cluster member node requires a Baseboard Management Controller (BMC) running firmware
compatible with IPMI version 1.5, which supports IPMI over LANs, and configured for remote
control.
