Specify Home Details

Specify the location of the Oracle base where you want to store all Oracle software and configuration-related files. The Oracle Base directory is the top-level directory that you can use to install the various oracle software products. You can use the same Oracle base directory for more than one installation. If different operating system users install Oracle software on the same system, then each user must create a separate Oracle base directory. If you have set the ORACLE_BASE environment variable, Oracle Universal Installer displays the value of the ORACLE_BASE variable as a default value for the Oracle Base field.

Oracle Base: Enter the complete path of the Oracle base directory, or select it from the list of paths to the existing Oracle homes. Alternatively, you can use the Browse button to specify a directory where you want to store all Oracle software and configuration-related files.

Software Location

Specify the name and location of the Oracle home where you want to install the product. Then, click Next.

Note: You must install a patch or patch set in an existing Oracle home. Select the Oracle home of the database that is being patched and click Next

Name: Enter an Oracle home name, or select it from the list.

If there is no Oracle home on your system, then an Oracle home is created for you during the installation. The name of this Oracle home is the text that you enter in the Name field.

Oracle homes are identified by name. On Microsoft Windows, the Oracle home name identifies the program group associated with a particular Oracle home and the Oracle services installed on the associated home. The Oracle home name can be up to 127 characters long and can only include alphanumeric characters and the underscore (_) character. The Oracle home name must not include spaces.

Path: Enter the complete path of the Oracle home directory, or select it from the list of paths to the existing Oracle homes. Alternatively, you can use the Browse button to specify a directory where you want to install the product.

The following are the types of Oracle homes that are maintained on UNIX-based platforms:

All Oracle homes that are already created using Oracle Universal Installer
All Oracle homes as defined in the /etc/oratab or /var/opt/oracle/oratab file, depending on the operating system
The directory specified by the ORACLE_HOME environment variable

The following are the types of Oracle homes that are maintained on Microsoft Windows platforms:

All Oracle homes that have been created using Oracle Universal Installer
All Oracle homes created using the previous Oracle installer (ORCA-based)
All Oracle homes listed in the Microsoft Windows registry

If none of these Oracle homes exist, then a default home is determined on the basis of the disk volume with the largest amount of free space.

The default Oracle home path is based on a value specified in the oraparam.ini file. On Microsoft Windows, this path includes the drive letter assigned to the disk volume with the maximum amount of free space. On UNIX-based platforms, the default path is determined as follows:

If the ORACLE_HOME environment variable is defined, then its value is used as the default path.
If the ORACLE_HOME environment variable is not defined, the default Oracle home path is a subdirectory in your Oracle home directory.
