Assigning IP Address. Prior to Oracle Clusterware 1. Release 2, the only method available for. IP addresses to each of the Oracle RAC nodes was to have the network administrator. IP addresses in DNS — never to use DHCP. This would include the public IP address for the node, the RAC interconnect, virtual IP address (VIP). Release 2, the. Single Client Access Name. SCAN) virtual IP address(s). Oracle Clusterware 1. Release 2 now provides two methods for assigning IP addresses. Oracle RAC nodes. Assigning IP addresses dynamically using. Grid Naming Service. GNS) which makes use of DHCP. The traditional method of manually assigning static IP addresses in. Domain Name Service. DNS). Assigning IP Addresses Dynamically using Grid Naming Service (GNS). A new method for assigning IP addresses was introduced in. Oracle Clusterware 1. Release 2 named Grid Naming Service (GNS). VIP addresses to be dynamically assigned using DHCP. GNS and DHCP are key elements to Oracle's new Grid Plug and Play (GPn. P). feature that, as Oracle states, eliminates per- node configuration. GNS enables a dynamic Grid Infrastructure. All name resolution requests for the cluster within a sub- domain delegated. DNS are handed off to GNS using multicast Domain Name Service (m. DNS). included within the Oracle Clusterware. Using GNS eliminates the need for. IP addresses and name resolution and is especially advantageous in. While assigning IP addresses using GNS certainly has its benefits and. IP addresses. it does come at the cost of complexity and requires components not defined in. For example, activating GNS in a cluster requires a DHCP server. Oracle RAC. The example Oracle RAC configuration described in this guide will. IP addresses in. To learn more about the benefits and how to configure GNS, please see. Oracle Grid Infrastructure Installation Guide 1. Release 2 (1. 1. 2) for Linux. Assigning IP Addresses Manually using Static IP Address - (The DNS Method). If you choose not to use GNS, manually defining static IP addresses is still. Oracle Clusterware 1. Release 2 and will be the method. Oracle Clusterware networking components. IP address for the node, RAC interconnect, virtual IP address, and. SCAN virtual IP). It should be pointed out that previous to Oracle 1. Release 2. the need for DNS in order to successfully configure Oracle RAC was. It was technically possible (although not. IP addresses only. This actually worked to my advantage with any of my previous articles. RAC because it was one less component to. So, why is the use of DNS now a requirement when manually assigning. IP addresses? The answer is. Oracle Clusterware 1. Release 2 requires the use of DNS in order to. SCAN virtual IP address(s). In addition to the requirement of configuring. SCAN virtual IP address in DNS, we will also configure the public and. IP address for all Oracle RAC nodes in DNS for name resolution. If you do not have access to a DNS, instructions will be included. DNS server on the Openfiler network storage server. When using the DNS method for assigning IP addresses, Oracle. IP addresses be manually configured. DNS before starting the Oracle Grid Infrastructure. Single Client Access Name (SCAN) for the Cluster. If you have ever been tasked with extending an Oracle RAC cluster by adding. RAC cluster by removing a node), then you know. SQL*Net. or JDBC configuration to reflect the new or deleted node. To address this problem, Oracle 1. Release 2 introduced a new. Single Client Access Name or SCAN for short. SCAN is a new feature that provides a single host name for clients to. Oracle Database running in a cluster. Clients using SCAN. TNS configuration if you add or remove nodes in the cluster. The SCAN resource and its associated IP address(s) provide a stable name. You will be asked to provide the host name. SCAN name in this document) and up to three IP addresses. SCAN resource during the interview phase of the. Oracle Grid Infrastructure installation. For high availability and scalability, Oracle recommends that you. SCAN name for round- robin resolution to three IP addresses. At a minimum, the SCAN must resolve to at least one address. The SCAN virtual IP name is similar to the names used for a node's. IP address, such as racnode. However. unlike a virtual IP, the SCAN is associated with the entire cluster.
