This section describes the Oracle Database 10g release 1 (10.1) features as they pertain to the installation and configuration of Real Application Clusters (RAC). The topic in this section is:
This book contains Oracle Database 10g pre-installation and installation instructions for UNIX- and Windows-based platforms on which RAC operates.
The Oracle Database 10g with RAC is available on both the Standard Edition and the Enterprise Edition.
The Oracle Database 10g installation requires you to perform a two-phase process in which you run the Oracle Universal Installer (OUI) twice. The first phase installs Oracle Cluster Ready Services Release 1 (10.1.0.2) and the second phase installs the Oracle Database 10g software with RAC. The installation also enables you to create and configure services for your RAC environment. If you have a previous Oracle cluster database version, then the OUI activates the Database Upgrade Assistant (DBUA) to automatically upgrade your pre-Oracle Database 10g cluster database. The Oracle Database 10g installation process provides single system image, ease of use, and accuracy for RAC installations and patches.
Cluster Ready Services (CRS) provides Oracle Database 10g RAC high availability components that provide many system management features. CRS components also interact with the vendor clusterware, if present, to coordinate cluster membership information.
There are new and changed pages and dialogs for the Oracle Universal Installer (OUI), the Database Configuration Assistant (DBCA), and the Database Upgrade Assistant. The Virtual Internet Protocol Configuration Assistant (VIPCA) is a new tool for this release. These enhancements are described in the following:
OUI Cluster Installation Mode Page—This page enables you to select whether to perform a cluster or a single-instance Oracle Database 10g installation.
SYS and SYSTEM Passwords Page—This page has fields for entering and confirming the SYS and SYSTEM user passwords. This includes SYSMAN and DBSNMP if you use Oracle Enterprise Manager Database Control.
Storage Options Page—This page has storage options for selecting the storage type for the database files such as control files, datafiles, and redo logs.
DBCA Services Page—This page enables you to create and configure services for your RAC environment.
DBCA Initialization Parameters Page—This page has two dialogs to display both Basic and Advanced parameter settings.
VIPCA—The pages for this assistant enable you to configure virtual internet protocol addresses for your RAC database.
A new auxiliary, system-managed tablespace called SYSAUX contains performance data and combines content that was stored in different tablespaces (some of which are no longer required) in earlier releases. This is a required tablespace for which you must plan disk space.
The gsdctl commands are obsolete. The CRS installation process stops any existing GSD processes.
Pre-Oracle Database 10g cluster manager implementations on some platforms were referred to as "Cluster Manager". The cluster manager on all platforms in Oracle Database 10g is known as Cluster Synchronization Services (CSS). The Oracle Cluster Synchronization Service Daemon (OCSSD) performs this function. On Windows-based platforms, the OracleCSService, OracleCRService, and OracleEVMService replace the pre-Oracle Database 10g OracleCMService9i.
Oracle Database 10g provides cluster file system support for Linux and Windows-based platforms.

RAC and the DBCA support Automatic Storage Management (ASM) and Oracle Managed Files (OMF).

The Oracle Database 10g version of the srvConfig.loc file is the ocr.loc file. The Oracle9i version of srvConfig.loc still exists for backward compatibility.
In Windows-based environments using raw partitions, you can use a newly-introduced raw device mapping file to associate database objects with their partition symbolic link names. This removes the pre-Oracle Database 10g requirement to always prefix raw partition symbolic links with a database name. This enables you to reuse the same raw partition symbolic links for any database.
