4 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:
For the most up-to-date information about supported network protocols and hardware for Oracle RAC installations, refer to the Certify pages on the My Oracle Support website. See "Checking Hardware and Software Certification on My Oracle Support" for instructions.- 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 Requirements
Review these requirements to ensure that you have the minimum network hardware technology for Oracle Grid Infrastructure clusters. - Oracle Grid Infrastructure IP Name and Address Requirements
The Oracle Grid Naming Service (GNS) is used with large clusters to ease network administration cost. - Intended Use of Network Adapters
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. - Broadcast Requirements for Networks Used by Oracle Grid Infrastructure
Broadcast communications address resolution protocol (ARP) and User Datagram Protocol (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
On each cluster member node the Oracle multicast DNS (mDNS) daemon uses multicasting on all network interfaces to communicate with other nodes in the cluster. - Configuring Multiple ASM Interconnects on Microsoft Windows Platforms
When using multiple network interface cards for the Oracle Automatic Storage Management (Oracle ASM) interconnect, you must enable theweakhostsendnetwork parameter.
