3 Installing Oracle Database

The Oracle Client software is available on DVD or you can download it from the Oracle Technology Network Web site. In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer to install the software. However, you can also use Oracle Universal Installer to complete silent-mode installations, without using the GUI.

3.1 Reviewing Installation Guidelines

Review the following guidelines before starting Oracle Universal Installer:

Oracle Universal Installer

Do not use Oracle Universal Installer from an earlier Oracle release to install components from this release.
Installations on a Cluster

If Oracle Clusterware and Oracle RAC are already installed on the system, Oracle Universal Installer displays the Specify Hardware Cluster Installation Mode screen. You must select Local Installation on this screen, unless you want to install Oracle RAC.

See Also:
Oracle Real Application Clusters Installation Guide for Linux and UNIX for information on installing Oracle RAC
Reinstalling Oracle Software

If you reinstall Oracle software into an Oracle home directory where Oracle Database is already installed, you must also reinstall any components, such as Oracle Partitioning, that were installed before you begin the reinstallation.

3.2 Accessing the Installation Software

The Oracle Client software is available on DVD or you can download it from the Oracle Technology Network Web site. To install the software from the hard disk, you must either download it from Oracle Technology Network and unpack it, or copy it from the DVD, if you have it.

You can access and install Oracle Database by using one of the following methods:

To install the software from a DVD or from an existing hard disk location, refer to "Installing the Oracle Client Software"
To copy the software to a hard disk, refer to "Copying the Software to the Hard Disk"
To download the software from Oracle Technology Network, refer to "Downloading Oracle Software from the Oracle Technology Network Web Site"

3.2.1 Downloading Oracle Software from the Oracle Technology Network Web Site

This section describes how to download the installation archive files and extract them on to the hard disk. It contains the following topics:

Downloading the Installation Archive Files
Extracting the Installation Files

3.2.1.1 Downloading the Installation Archive Files

To download the installation archive files from Oracle Technology Network:

Use any browser to access the software download page from Oracle Technology Network:
```
http://www.oracle.com/technology/software/
```
Navigate to the download page for the product that you want to install.
On the download page, identify the required disk space by adding the file sizes for each required file.

The file sizes are listed next to the file names.
Select a file system with enough free space to store and expand the archive files.

In most cases, the available disk space must be at least twice the size of all of the archive files.
On the file system that you selected in step 4, create a parent directory for each product, for example OraDB11g, to hold the installation directories.
Download all of the installation archive files to the directory that you created in step 5.
Verify that the files you downloaded are the same size as the corresponding files on Oracle Technology Network.

3.2.1.2 Extracting the Installation Files

To extract the installation archive files, perform the following steps:

If necessary, change directory to the directory that contains the downloaded installation archive files.
If the downloaded file has the zip extension, use the following command to extract the content:
```
unzip file_name.zip
```
If the downloaded file has the cpio.gz extension, use the following command:
```
$ gunzip filename.cpio.gz
```
This command creates files with names similar to the following:
```
filename.cpio
```
To extract the installation files, enter a command similar to the following:
```
$ cpio -idcmv < filename.cpio
```
Note:
Refer to the download page for information about the correct options to use with the cpio command.
Some browsers uncompress files while downloading them, but leave the .gz file extension.

For each file, this command creates a subdirectory named Diskn, where n is either 1 or the disk number identified in the file name.

When you have extracted all of the required installation files, refer to "Installing the Oracle Client Software".

3.2.2 Copying the Software to the Hard Disk

Before installing Oracle Database, you might want to copy the software to the hard disk. This enables the installation process to run a bit faster. Before copying the DVD content to the hard disk, you must mount the disk. The following sections describe to mount disk and copy its content to the hard disk.

3.2.2.1 Mounting Disks

On most Linux systems, the disk mounts automatically when you insert it into the DVD drive. If the disk does not mount automatically, then follow these steps to mount it:

If necessary, enter a command similar to one of the following to eject the currently mounted disk, then remove it from the drive:
- Asianux, Oracle Enterprise Linux, and Red Hat Enterprise Linux:
```
$ sudo eject /mnt/dvd
```
- SUSE Linux Enterprise Server:
```
# eject /media/dvd
```
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the DVD drive.
Insert the appropriate DVD into the disk drive.
To verify if the disk is mounted automatically, enter one of the following commands depending on the platform:
- Asianux, Oracle Enterprise Linux, and Red Hat Enterprise Linux:
```
# ls /mnt/dvd
```
- SUSE Linux Enterprise Server:
```
# ls /media/dvd
```
If this command fails to display the contents of the DVD, enter a command similar to the following to mount it, depending on the platform:

Note:
Before running the following command, ensure that the /mnt/dvd directory exists on Red Hat Enterprise Linux. If not, create the /mnt/dvd as required, to mount the DVD.
- Asianux, Oracle Enterprise Linux, and Red Hat Enterprise Linux:
```
# mount -t iso9660 /dev/dvd /mnt/dvd
```
- SUSE Linux Enterprise Server:
```
# mount -t iso9660 /dev/dvd /media/dvd
```
In these examples, /mnt/dvd and /media/dvd are the mount point directories for the DVD drive.
If Oracle Universal Installer is displaying the Disk Location dialog box, enter the disk mount point directory path, for example:
```
/mnt/dvd
```

To continue, go to one of the following sections:

If you want to copy software to a hard disk, refer to "Copying the Oracle Client Software to a Hard Disk".
If you want to install the software from the DVD, refer to "Installing the Oracle Client Software".

3.2.2.2 Copying the Oracle Client Software to a Hard Disk

If the system does not have a DVD drive, you can copy the software from the DVD to a file system on another system, then either mount that file system using NFS, or use FTP to copy the files to the system where you want to install the software.

To copy the contents of the DVD to a hard disk:

Create a directory on the hard disk to hold the Oracle software:
```
$ mkdir OraCl11g
```
Change directory to the directory you created in step 1:
```
$ cd OraCl11g
```
Mount the disk, if it is not already mounted.

Some platforms automatically mount the disk when you insert it into the drive. If the disk does not mount automatically, refer to the "Mounting Disks" section for platform-specific information about mounting it.
Copy the contents of the mounted disk to the corresponding new subdirectory as follows:
```
$ cp -R /directory_path OraCl11g
```
In this example, /directory_path is the disk mount point directory, for example /mnt/dvd on Red Hat Enterprise Linux systems, or the path of the client directory on the DVD. The mount point directory is /dvd.
If necessary, mount the next disk and repeat step 5.

3.3 Installing the Oracle Client Software

Use OUI to install the Oracle Database software.The following section describes how to install the Oracle software:

3.3.1 Running Oracle Universal Installer
