3 Installation Tasks

This chapter describes how to start the Oracle Universal Installer and install Oracle products on your system. It includes information about the following topics:

Note:

Review the information in Chapter 1, " Installation Overview" and complete the tasks listed in Chapter 2, " Pre-installation Tasks" before beginning the installation.

Installation Overview
Download Oracle Software from the OTN Web Site
Copy the Oracle Client Software to a Hard Disk
Install the Oracle Client Software

Installation Overview

The Oracle Client software is available on disc (CD-ROM or DVD-ROM) or you can download it from the Oracle Technology Network (OTN) Web site. In most cases, you use the graphical user interface (GUI) provided by the Oracle Universal Installer to install the software. However, you can also use the Installer to complete non-interactive installations, without using the GUI. See Appendix B for information about non-interactive installations.

This chapter describes how to install Oracle Client from the product media or from the hard disk. To install the software from the hard disk, you must either download it from OTN and unpack it, or copy it from the discs, if you have them. See one of the following sections, depending on the method that you want to use:

To copy the software to a hard disk, see the "Copy the Oracle Client Software to a Hard Disk" section.
To install the software from disc or from an existing hard disk location, see the "Install the Oracle Client Software" section.

To download the software from OTN, see the following section.

Download Oracle Software from the OTN Web Site

This section describes how to download the installation archive files and extract them on your hard disk.

Downloading the Installation Archive Files

To download the installation archive files from OTN:

Use any browser to access the software download page on OTN:
```
http://otn.oracle.com/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 filenames.
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 OraCli10g, 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 OTN.

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.
To uncompress each file, enter a command similar to the following:
```
$ gunzip filename.cpio.gz
```
This command creates files with names similar to the following:
```
filename.cpio
```
To extract the installation files, enter commands similar to the following:
```
$ cpio -idmv < filename.cpio
```
Note:
Some browsers uncompress files while downloading them, but leave the .gz file extension. If these steps do not work, remove the .gz extension from the files and repeat step 3.

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

When you have extracted all of the required installation files, see the "Install the Oracle Client Software" section.

C opy the Oracle Client Software to a Hard Disk

If your system does not have a CD-ROM or DVD-ROM drive, you can copy the software from the disc 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 disc to a hard disk:

Create a single directory on the hard disk to hold the Oracle software:
```
$ mkdir OraCli10g
```
Change directory to the directory you created in step 1:
```
$ cd OraCli10g
```
Mount the disc, if it is not already mounted.

Some platforms automatically mount the disc when you insert it into the drive. If the disc does not mount automatically, see Appendix A for platform-specific information about mounting it.

Copy the contents of the mounted disc to the corresponding new subdirectory as follows:

$ cp -R /directory_path Disk1

In this example, /directory_path is the CD-ROM mount point directory or the path of the client directory on the DVD-ROM. The following table lists typical mount point directories for each platform:

Platform	Mount Point
AIX, Tru64 UNIX	`/cdrom`
HP-UX	`/SD_CDROM`
Linux (Red Hat)	`/mnt/cdrom`
Linux (UnitedLinux)	`/media/cdrom`
Solaris (mounted automatically)	`/cdrom/cdrom0`
Solaris (mounted manually)	`/cdrom`

Install the Oracle Client Software

The following sections describe how to install the Oracle software:

Reviewing Product-Specific Installation Guidelines
Running the Oracle Universal Installer

Reviewing Product-Specific Installation Guidelines

Review the following guidelines before starting the Installer:

Oracle Universal Installer

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

If Oracle Cluster Ready Services (CRS) and Oracle Real Application Clusters (RAC) are already installed on the system, the Installer displays the Specify Hardware Cluster Installation Mode screen. You must select Local Installation on this screen.
Re-installing Oracle Software

If you re-install Oracle software into an Oracle home directory where Oracle Client is already installed, you must also re-install any components that were installed before you began the re-installation.

Running the Oracle Universal Installer

Start the Installer and install the software, as follows:

If you are installing the software from disc, mount the appropriate disc if it is not already mounted.

Some platforms automatically mount discs when you insert them into the drive. If the disc does not mount automatically, see Appendix A for platform-specific information about mounting it.
If necessary, log in as the Oracle software owner user (oracle) and set the DISPLAY environment variable.
To start the Installer, enter the following commands where directory_path is the CD-ROM mount point directory or the path of the client directory on the DVD-ROM:
```
$ cd /tmp
```
```
$ /directory_path/runInstaller
```
If the Installer does not appear, see the "X Windows Display Errors" section for information troubleshooting.

Use the following guidelines to complete the installation:

Follow the instructions displayed in the Installer windows. If you need additional information, click Help.
When the Installer prompts you to run a script with root privileges, enter a command similar to the following in a terminal where you are logged in as the root user, then click Continue or OK:
```
# /script_path/script_name
```

On Tru64 UNIX, when prompted for the JDK home directory specify the location of JDK 1.4.2 on your system.

To determine the JDK home directory, enter the following command:

# /usr/sbin/setld -i JAVA142 | more

The default location is /usr/opt/java142.

Caution:

The Oracle Universal Installer automatically installs the Oracle-supplied version of the Java Runtime Environment (JRE). This version is required to run Oracle Universal Installer and several Oracle assistants. Do not modify the JRE except by using a patch provided by Oracle Support Services.

If you encounter errors while installing or linking the software, see Appendix D for information about troubleshooting.

If you chose an installation type that runs Oracle Net Configuration Assistant (NetCA) in interactive mode, you must provide detailed information about configuring your network.

If you need assistance when using NetCA in interactive mode, click Help on any screen.

Note:
If you chose a default installation, NetCA runs non-interactively.
When all of the configuration tools have finished, click Exit, then click Yes to exit from the Installer.
See Chapter 4, " Post-installation Tasks" for information about tasks that you must complete after you have installed the software.
