"Oracle Upgrade Companion" is available through Note 785351.1 on My Oracle Support:</p> <p><code><a href="https://support.oracle.com/">https://support.oracle.com/</a></code></p> <p>For upgrades, note the following:</p> <ul> <li> <p>You can have only one version of Oracle Clusterware running on a cluster at a time. It must be the most recent release of any software (Oracle Clusterware, Oracle Database, Oracle RAC and Oracle Automatic Storage Management) running on the cluster. So, before upgrading your database to Oracle Database 11g release 2, all nodes in the cluster must be upgraded to Oracle Clusterware and Oracle ASM 11<span class="italic">g</span> release 2 (11.2).</p> </li> <li> <p>You can have <a id="sthref55" name="sthref55"></a><a id="sthref56" name="sthref56"></a><a id="sthref57" name="sthref57"></a>multiple Oracle homes of Oracle Database software on your cluster. However, the Oracle RAC database software in these homes must be from a version that is equal to or less than the version of Oracle Clusterware that is installed; you cannot use a version of Oracle Database that was released after the version of Oracle Clusterware that you are running.</p> <p>For example:</p> <ul> <li> <p>If you have Oracle Clusterware 11<span class="italic">g</span> release 2 installed as your clusterware, then you can have an Oracle Database 10<span class="italic">g</span> release 2 single-instance database running on one node, and separate Oracle RAC 10<span class="italic">g</span> release 1, release 2, and Oracle RAC 11<span class="italic">g</span> release 1 or release 2 databases also running on the cluster.</p> </li> <li> <p>You cannot have Oracle Clusterware 10<span class="italic">g</span> release 2 installed on your cluster, and install Oracle RAC 11<span class="italic">g</span>.</p> </li> </ul> </li> <li> <p>Starting with release 10.1.0.6 and 10.2.0.3, you can use Database Upgrade Assistant (DBUA) for patch set upgrades with Oracle RAC. You can also use DBUA to upgrade between major point releases of Oracle RAC (for example, from 10.2 to 11<span class="italic">g</span>, or 11.1 to 11.2).</p> </li> <li> <p>For the Oracle RAC database being upgraded, DBUA must be run on a node where one of the Oracle RAC database instances is running.</p> </li> <li> <p>For the Oracle RAC database being upgraded, each cluster member node that hosts an instance of the database must be a member of the upgraded installation. For example, if you have an existing Oracle RAC database running on a three node cluster, then you must upgrade Oracle RAC on all three nodes. You cannot upgrade only 2 nodes of the cluster, removing the third node and instance in the upgrade.</p> </li> </ul> <div class="infoboxnote"> <p class="notep1">Note:</p> If you are <a id="sthref58" name="sthref58"></a>upgrading an existing Oracle RAC installation, then you must use the same type of Oracle home that you have in your existing installation. For example, if you have a shared Oracle home in your existing installation, then you must upgrade to a shared Oracle home with Oracle RAC 11<span class="italic">g</span> release 2 (11.2). <p>Similarly, if you have local Oracle homes on cluster nodes, then you must upgrade to local Oracle homes on cluster nodes.</p> </div> <div class="infoboxnotealso"> <p class="notep1">See Also:</p> <a class="olink UPGRD" href="http://www.oracle.com/pls/db112/lookup?id=UPGRD"><span class="italic">Oracle Database Upgrade Guide</span></a> for information about how to prepare for upgrading an existing database</div> </div> <!-- class="sect2" --> <a id="BHAGIACF" name="BHAGIACF"></a><a id="RIWIN968" name="RIWIN968"></a> <div class="sect2"><!-- infolevel="all" infotype="General" --> <h3 class="sect2"><span class="secnum">1.1.6</span> Review Globalization Requirements</h3> <p>Before <a id="sthref59" name="sthref59"></a><a id="sthref60" name="sthref60"></a>you start an installation where you want to support languages other than English, review <span class="italic">Oracle Database Globalization Support Guide</span>.</p> <p>Note the following:</p> <ul> <li> <p>Oracle recommends that you use Unicode AL32UTF8 as the database character set.</p> <p>Unicode is the universal character set that supports most of the currently spoken languages of the world. It also supports many historical scripts (alphabets). Unicode is the native encoding of many technologies, including Java, XML, XHTML, ECMAScript, and LDAP. Unicode is ideally suited for databases supporting the Internet and the global economy.</p> </li> <li> <p>The locale setting of your operating system session determines the language of the user interface, and the globalization behavior for components such as Oracle Universal Installer, Oracle Net Configuration Assistant, and Database Configuration Assistant. It also determines the globalization behavior of Oracle Database sessions created by a user application through Oracle JDBC driver, unless overridden by the application.</p> </li> <li> <p>The <code>NLS_LANG</code> character set should reflect the setting of the operating system character set of the client. For example, if the database character set is AL32UTF8 and the client is running on a Windows operating system, then you should not set AL32UTF8 as the client character set in the <code>NLS_LANG</code> parameter because there are no UTF-8 WIN32 clients. Instead, the <code>NLS_LANG</code> setting should reflect the code page of the client. For example, on an English Windows client, the code page is 1252. An appropriate setting for <code>NLS_LANG</code> is <code>AMERICAN_AMERICA.WE8MSWIN1252</code>.</p> </li> </ul> <div class="infoboxnote"> <p class="notep1">Note:</p> <a class="olink GINST" href="http://www.oracle.com/pls/db112/lookup?id=GINST"><span class="italic">Oracle Database Installation Guide</span></a> contains a fuller discussion of database character sets used with different languages, and provides further information about installing and configuring Oracle Database globalization support.</div> </div> <!-- class="sect2" --> <a id="BHABABDG" name="BHABABDG"></a><a id="RIWIN969" name="RIWIN969"></a> <div class="sect2"><!-- infolevel="all" infotype="General" --> <h3 class="sect2"><span class="secnum">1.1.7</span> Review Documentation</h3> <p>Users planning to install Oracle Real Application Clusters should review <a class="olink CWWIN" href="../../install.112/e10817/toc.htm"><span class="italic">Oracle Grid Infrastructure Installation Guide for Microsoft Windows</span></a>, particularly the preinstallation and storage chapters, to complete all required steps needed for a successful installation.

Files supported by Oracle ACFS include database and application executables, trace files, alert logs, application reports, BFILEs, and configuration files. Oracle ACFS leverages Oracle ASM functionality that enables Oracle ACFS dynamic file system resizing, maximized performance through direct access to Oracle ASM disk group storage, balanced distribution of Oracle ACFS across Oracle ASM disk group storage for increased I/O parallelism, and data reliability through Oracle ASM mirroring protection mechanisms.</p> <p><a id="sthref90" name="sthref90"></a><a id="sthref91" name="sthref91"></a>The Oracle ASM Dynamic Volume Manager (Oracle ADVM) provides volume management services and a standard disk device driver interface to clients.

Oracle ADVM extends Oracle ASM by providing a disk driver interface to Oracle ASM storage allocated as Oracle ASM volume files. You can use the Dynamic Volume Manager to create virtual disks that contain file systems.
