In most cases, you use the graphical user interface (GUI) provided by the Oracle Universal Installer to install the software. However, you can also use the Oracle Universal Installer to complete non-interactive (or "silent") installations, without using the GUI.</p> <p>The Oracle inventory maintains records of Oracle software versions and patches. Each installation has a Central Inventory where the Oracle home is registered. Oracle software installations have a local home directory, whose path location is recorded in the Central Inventory. The local inventory directory for each Oracle software installation contains a list of components and applied interim patches associated with that software. Because faulty inventory information can corrupt your Oracle software installation, the Oracle Universal Installer must perform all read and write operations on Oracle inventories. Ensure that you do not modify files in the Central Inventory or the Oracle home inventory.</p> <p>When you install Oracle Clusterware or Oracle Real Application Clusters, the Oracle Universal Installer copies the Oracle software onto the node from which you are running it. If your Oracle home is not on a shared file system, the Oracle Universal Installer propagates the software onto the other nodes that you have selected to be part of your Oracle Universal Installer installation session. The Oracle inventory maintains a list of each node that is a member of the Oracle Real Application Clusters database, and lists the paths to each node's Oracle home. This is used to maintain patches and updates for each member node of the Oracle Real Application Clusters database.</p> <p>When the Oracle Universal Installer installs the Oracle software, Oracle recommends that you select a preconfigured database, or use the Database Configuration Assistant (DBCA) interactively to create your cluster database. You can also manually create your database as described in procedures posted on the Oracle Technical Network, which is at the following URL:</p> <pre xml:space="preserve" class="oac_no_warn">http://www.oracle.com/technology/index.htm </pre> <p>Oracle recommends that you use Automatic Storage Management (ASM). If you are not using ASM, or if you are not using a cluster file system, then configure shared raw devices before you create your database.</p> <p>Oracle software provides additional components to operate Oracle Real Application Clusters. Some of the Oracle Real Application Clusters-specific components include:</p> <ul> <li> <p>Oracle Clusterware</p> </li> <li> <p>Installed Oracle Real Application Clusters Components</p> </li> </ul> <div class="sect2"><!-- infolevel="all" infotype="General" --><a id="sthref426" name="sthref426"></a> <h3 class="sect2"><a name="OUICG220" id="OUICG220"></a><a id="sthref427" name="sthref427"></a><a id="sthref428" name="sthref428"></a>Oracle Clusterware</h3> <p>The Oracle Universal Installer installs Oracle Clusterware on each node on which the Oracle Universal Installer detects that third-party vendor clusterware is present. If third-party vendor clusterware is not present, you must use the Oracle Universal Installer to enter the nodes on which you want the Oracle Clusterware to be installed. The Oracle Clusterware home can be either shared by all nodes, or private to each node, depending on your responses when you run the Oracle Universal Installer.</p> <p>When third-party vendor clusterware is present, Oracle Clusterware can interact with the third-party vendor clusterware. In using third-party vendor clusterware, note that Oracle Clusterware can integrate with third-party vendor clusterware for all operating systems except Linux and Windows. You need to have Oracle Cluster Registry and Voting Disks shared across all nodes.</p> </div> <!-- class="sect2" --> <div class="sect2"><!-- infolevel="all" infotype="General" --><a id="sthref429" name="sthref429"></a> <h3 class="sect2"><a name="OUICG221" id="OUICG221"></a><a id="sthref430" name="sthref430"></a>Installed Oracle Real Application Clusters Components</h3> <p>All instances in an Oracle Real Application Clusters environment share the control file, server parameter file, redo log files, and all data files. These files reside on a shared cluster file system or on shared disks. Either of these types of file configurations are accessed by all the cluster database instances. Each instance also has its own set of redo log files.

Review these options before you decide which storage option to use in your Oracle Real Application Clusters environment.</p> </li> <li> <p>One private Internet protocol (IP) address for each node to serve as the private interconnect. The following must be true for each private IP address:</p> <p>– It must be separate from the public network.– It must be accessible on the same network interface on each node.– It must have a unique address on each node.The private interconnect is used for inter-node communication by both Oracle Clusterware and Oracle Real Application Clusters. If the private address is available from a network name server (DNS), you can use that name. Otherwise, the private IP address must be available in each node's <code>/etc/hosts</code> file on UNIX and <code>%SystemRoot%\system32\drivers\etc\hosts</code> on Windows.</p> <p>During Oracle Clusterware installation, the information you enter as the private IP address determines which private interconnects are used by Oracle Real Application Clusters database instances.</p> </li> <li> <p>One public IP address for each node to be used as the Virtual IP address for client connections and for connection failover.</p> <p>This public Virtual IP address (VIP) must be associated with the same interface name on every node that is part of your cluster. Additionally, the IP addresses that you use for all of the nodes that are part of a cluster must be from the same subnet. If you have a domain name server (DNS), register the host names for the VIP with DNS. The Virtual IP address should not be in use at the time of the installation, because this is a Virtual IP address that Oracle manages.</p> </li> <li> <p>One public fixed host name address for each node, typically assigned by the system administrator during operating system installation. If you have a DNS, register both the fixed IP and the VIP address with DNS.

Oracle Universal Installer uses the <code>ssh</code> and <code>scp</code> commands during installation to run remote commands on and copy files to the other cluster nodes. You must configure SSH so that these commands do not prompt for a password. SSH is also used by the configuration assistants, Enterprise Manager, and when adding nodes to the cluster.</p> <p>You can configure SSH from the Oracle Universal Installer (OUI) interface during installation for the user account running the installation. The automatic configuration creates passwordless SSH connectivity between all cluster member nodes. You can use an SSH Connectivity button available in the Cluster Node information page for this purpose.</p> <p>To enable the script to run, you must remove stty commands from the profiles of any Oracle software installation owners, and remove other security measures triggered during a login and that generate messages to the terminal. These messages, mail checks, and other displays prevent Oracle software installation owners from using the SSH configuration script that is built into the Oracle Universal Installer. If they are not disabled, you must manually configure SSH before running an installation.</p> <p>On Linux systems, to enable Oracle Universal Installer to use the ssh and scp commands without being prompted for a pass phrase, you must have user equivalency in the cluster. User equivalency exists in a cluster when the following occurs on all nodes in the cluster:</p> <ul> <li> <p>A given user has the same user name, user ID (UID), and password.</p> </li> <li> <p>A given user belongs to the same groups.</p> </li> <li> <p>A given group has the same group ID (GID).</p> </li> </ul> <div class="infoboxnote"> <p class="notep1">Note:</p> This section describes how to configure <a id="sthref457" name="sthref457"></a><a id="sthref458" name="sthref458"></a>OpenSSH version 3. If SSH is not available, then Oracle Universal Installer attempts to use <code>rsh</code> and <code>rcp</code> instead.
