5 Configuring Networks for Oracle Grid Infrastructure and Oracle RAC
Check that you have the networking hardware and internet protocol (IP) addresses required for an Oracle Grid Infrastructure for a cluster installation.
Note:
If you have a firewall running, ensure that all the required ports are open. See, Port Numbers and Protocols of Oracle Components for a list of port numbers and protocols configured for Oracle Database components.- About Oracle Grid Infrastructure Network Configuration Options
Ensure that you have the networking hardware and internet protocol (IP) addresses required for an Oracle Grid Infrastructure for a cluster installation. - Understanding Network Addresses
During installation, you are asked to identify the planned use for each network interface that Oracle Universal Installer (OUI) detects on your cluster node. - Network Interface Hardware Minimum Requirements
Review these requirements to ensure that you have the minimum network hardware technology for Oracle Grid Infrastructure clusters. - Private IP Interface Configuration Requirements
Requirements for private interfaces depend on whether you are using single or multiple Interfaces. - IPv4 and IPv6 Protocol Requirements
Oracle Grid Infrastructure and Oracle RAC support the standard IPv6 address notations specified by RFC 2732 and global and site-local IPv6 addresses as defined by RFC 4193. - Oracle Grid Infrastructure IP Name and Address Requirements
Review this information for Oracle Grid Infrastructure IP Name and Address requirements. - Broadcast Requirements for Networks Used by Oracle Grid Infrastructure
Broadcast communications (ARP and UDP) must work properly across all the public and private interfaces configured for use by Oracle Grid Infrastructure. - Multicast Requirements for Networks Used by Oracle Grid Infrastructure
For each cluster member node, the Oracle mDNS daemon uses multicasting on all interfaces to communicate with other nodes in the cluster. - Domain Delegation to Grid Naming Service
If you are configuring Grid Naming Service (GNS) for a standard cluster, then before installing Oracle Grid Infrastructure you must configure DNS to send to GNS any name resolution requests for the subdomain served by GNS. - Configuration Requirements for Oracle Flex Clusters
Understand Oracle Flex Clusters and their configuration requirements. - Grid Naming Service Cluster Configuration Example
Review this example to understand Grid Naming Service configuration. - Manual IP Address Configuration Example
If you choose not to use GNS, then before installation you must configure public, virtual, and private IP addresses. - Network Interface Configuration Options
During installation, you are asked to identify the planned use for each network adapter (or network interface) that Oracle Universal Installer (OUI) detects on your cluster node. - Multiple Private Interconnects and Oracle Linux
Review this information for settings for therp_filterparameter for Oracle RAC systems that use multiple NICs for the private interconnect. - Creating SCAN Client Data File
Generate a SCAN client data file and copy the file to the SCAN client cluster member node on which you are installing Oracle Grid Infrastructure.
