This chapter describes how to use the Oracle Universal Installer (OUI) to install the Oracle9i Enterprise Edition and the Real Application Clusters software. The topics in this chapter include:
Perform the procedures in this chapter only after configuring your disk subsystem as described in Chapter 2, and before continuing with the procedures for using the Oracle Database Configuration Assistant (DBCA) as described in Chapter 4.
Note:
Follow these procedures to use the Oracle Universal Installer to install the Oracle Enterprise Edition and the Real Application Clusters software.

Enter the following command for each node that is a part of the cluster where node_name is the node name returned from the
Oracle Corporation recommends using the same user name and password on each node in a cluster or use a domain user name. If you use a domain user name, log on under a domain with a username and password that has administrative privileges on each node. |
Then for UNIX platforms only, set the environment variables as described in the following two steps, otherwise, proceed to step 4.
ORACLE_HOME
on your cluster for Real Application Clusters, then set the SRVM_SHARED_CONFIG
environment variable to the name of the 100MB volume raw device or shared file that you set up for the configuration storage by entering, for example:
setenv SRVM_SHARED_CONFIG shared_filename
If your platform supports a cluster file system, make sure the partition on which this file resides has least 100MB of free space.
DBCA_RAW_CONFIG
environment variable. Do this, for example, by executing the following where filename is the name of the ASCII file containing the configuration information:
setenv DBCA_RAW_CONFIG filename
For the Customized configuration type, if this is the first installation on your cluster and you have not set the environment variable, then the Installer prompts you for the name of the 100MB file by displaying the Raw Device Name page.
Path
field under the Destination
heading, enter the name of the Oracle home into which you are going to install the Oracle Enterprise Edition and Real Application Clusters software.
Before continuing, read the following description about how the Oracle Database Configuration Assistant creates your database and about the underlying configuration that it creates. This section also describes the configuration types.
However, if you are familiar with the DBCA and have decided on a database configuration type, proceed to one of the following sections:
When you run the Oracle Universal Installer and select the Oracle9i Enterprise Edition, you can select the General Purpose, Transaction Processing, Data Warehouse, or Customized database configuration type for Real Application Clusters. For the first three configuration types, you must complete the procedures described later in this chapter. Then the Installer runs without further input.
If you select the Customized configuration in the Installer, then you can use the DBCA to create the database as described in Chapter 4 or create the database manually as described in Chapter 5. You can also select the Customized configuration and use the DBCA to create a database using a customized version of one of the preconfigured templates. These templates correspond to the Installer's configuration types of General Purpose, Transaction Processing, and Data Warehouse. The DBCA can also use the New Database template to create a database.
To manually configure your environment, you can select the Software Only database configuration option. However, Oracle Corporation strongly recommends that you use one of the preconfigured database options or use the New Database option and the DBCA.
The configuration type that you select determines how you proceed. Table 3-2 describes the installation types.
Configuration Type | Description | Advantages |
---|---|---|
Data Warehouse, Transaction Processing, General Purpose |
Installs a preconfigured starter database, licensable Oracle options (including Oracle9i Real Application Clusters), networking services, Oracle9i utilities, and online documentation. At the end of the installation, the Database Configuration Assistant creates a Real Application Clusters database and configures it for use. |
Minimal input required. You can create your database more quickly than with the Customized type. |
Customized |
Allows you customize your database options and storage components. |
Enables you to create arbitrary tablespaces and datafiles and customize all aspects of your database. |
Software Only |
Installs only the software. Does not configure the listeners or network infrastructure. |
-- |
If you select one of the first three configuration types on the Installer's Database Configuration screen, complete the procedures in this chapter under the heading "Using the General Purpose, Transaction Processing, and Data Warehouse Database Configuration Types". These three configuration types use preconfigured templates. As mentioned, after you complete these procedures, the OracleNet Configuration Assistant and the DBCA run without further input.
The DBCA processing for these configuration types creates a starter database and configures the Oracle network services. As mentioned, if your platform does not support a cluster file system, then the DBCA verifies that you configured the raw devices for each tablespace.
Note:
If you have not properly configured the raw devices as described in Chapter 2, the DBCA cannot create your database. |
If you select the Customized configuration you must enter specific information as described in the next section.
If you select the Customized configuration type, the Oracle Universal Installer runs the Oracle Database Configuration Assistant which offers you a choice of four database templates:
The first three templates create a database that is optimized for that particular environment. You also can customize these templates as required.
The New Database type, however, creates a database without using preconfigured options. Therefore, you must enter specific raw device information for the datafiles to complete a New Database installation as described in Chapter 4, "Creating Databases with the Oracle Database Configuration Assistant".
The following section provides more detail on Oracle Database Configuration Assistant processing when it creates a Real Application Clusters database.
The Oracle Database Configuration Assistant (DBCA) runs as part of the Oracle Universal Installer installation process. When the Installer begins processing, the Oracle Net Configuration Assistant runs. If you configured directory access with the Oracle Net Configuration Assistant, the DBCA will add an entry for the database service to the directory. Clients that you configured with directory access can also access the network information for the database service and connect to the database without a tnsnames.ora
file.
After the OracleNet Configuration Assistant completes its processing, the DBCA creates your database using the optimal flexible architecture (OFA). This means the DBCA creates your database files, including the default server parameter file, using standard file naming and file placement practices. The primary phases of DBCA processing are:
You can also use the DBCA in standalone mode to create a database.

Continuing from Step 7 , execute the following procedures to complete a General Purpose, Transaction Processing, or Data Warehouse configuration:
lsnodes -v
command and analyzing its output according to the following platform-specific instructions.
For UNIX platforms, execute the lsnodes -v
command from the /tmp/OraInstall
directory. Refer to your vendor's clusterware documentation if the output indicates that your clusterware is not properly installed.
For these Windows platforms, execute the lsnodes -v
command from the preinstall_rac
directory.
lsnodes -v
Refer to your clusterware documentation if the detailed output indicates that your clusterware is not running.
Each instance has a sid
that comprises the common prefix you enter in this step and a thread ID that is automatically generated. For example, if you enter db
for the sid
, the first database instance is given a sid
of db1db1
, and the second instance is given a sid
of db2
. Click Next.
During installation, the installer does not display messages indicating which components are installed on the remote nodes.
When you complete these procedures, you are ready to administer and deploy your Real Application Clusters environment as described in Oracle9i Real Application Clusters Administration and Oracle9i Real Application Clusters Deployment and Performance.
Continuing from Step 7 on , execute the following procedures to complete a Customized configuration:
lsnodes -v
command and analyzing its output according to the following platform-specific instructions.
For UNIX platforms, execute the lsnodes -v
command from the /tmp/OraInstall
directory. Refer to your vendor's clusterware documentation if the output indicates that your clusterware is not properly installed.
For these Windows platforms, execute the lsnodes -v
command from the preinstall_rac
directory.
lsnodes -v
Refer to your clusterware documentation if the detailed output indicates that your clusterware is not running.
sid
for each instance.
Each instance has a sid
that comprises the common prefix you enter in this step and a thread ID that is automatically generated. For example, if you enter db
for the sid
, the first database instance is given a sid
of db1
, and the second instance is given a sid
of db2
. Click Next.
The Installer displays the Database Character Set page on which you must select a character set and click Next.
During installation, the Installer does not display messages indicating that the components are being installed on the remote nodes.
When you complete these procedures, proceed to Chapter 4, "Creating Databases with the Oracle Database Configuration Assistant".
