Using Windows ClusterThis section discusses the steps involved in setting up a RAC system on a Windows platform. Hardware / System DetailsThere are different configurations for Windows NT and 2000. Please consult the specific Hardware/Software/Variance information provided by your hardware vendor. Fig 6.12 shows the certified combination of servers/processors, interconnect technology, and storage types. Fig 6.12 Windows based Clusters However, there are some restrictions as shown below:
This information is likely to change, as Oracle and other vendors continuously certify new hardware. It is suggested that the reader consult the hardware vendor to find out the latest position of certification. Setup the External and Internal NICFirst, set up the servers or nodes with the appropriate operating system and apply the necessary service packs. Within the network settings of Windows, create at least two entries for the NIC(s) that have been installed. When assigning the bindings of the NIC(s) within the Windows Networking Properties, ensure that the public IP is listed at the top for all settings. The private NIC(s) should be listed below the public NIC settings. This can be verified at the command prompt by running the command ipconfig /all to verify that the public IP address is listed first. It is recommended to use a network switch for interconnecting between nodes rather than a crossover cable. Most cluster hardware vendors will have this as a requirement. Also, ensure that the external or public hostnames are defined in the directory network services (DNS), and that the correct IP addresses resolve for all nodes in the cluster. Ensure that the internal or private hostnames are defined in the HOST file on all nodes of the cluster. This file is located in the WINDOWS_HOME\System32\drivers\etc directory. Checking Access to Other Nodes within WindowsOracle recommends using either the same username or password on each node in a cluster, or a domain username with administrative privileges on all local nodes when installing or performing administrative tasks. All nodes must be in the same domain. Ensure that each node has administrative access to all directories within the Windows environment by running the following at the command prompt: NET USE \\host_name\C$ The hostname is the public network name for the other nodes. If we plan to install the ORACLE_HOME onto a drive location other than C:\ check that administrative share as well. For example, if the WIN_HOME is on the C:\ drive and we are installing the ORACLE_HOME onto the E:\ drive of all nodes, we will run the following from a command prompt on node 1 of a four-node cluster: NET USE \\node2\C$ NET USE \\node3\C$ NET USE \\node4\C$ NET USE \\node2\E$ NET USE \\node3\E$ NET USE \\node4\E$ For more information, see the book Oracle 11g Grid and Real Application Clusters - 30% off if you buy it directly from Rampant TechPress .
