3.2 Accessing the Installation Software

The Oracle Client software is available on compact disc (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 disc, if you have it.

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

To copy the software to a hard disk, refer to the following section:

"Copying the Software to the Hard Disk"
To install the software from a disc or from an existing hard disk location, refer to the "Installing the Oracle Client Software" section.
To download the software from Oracle Technology Network, refer to the following section.

3.2.1 Downloading Oracle Software from the OTN Web Site

This section describes how to download the installation archive files and extract them on your 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 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 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.
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 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. 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 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 Client, you might want to copy the software to the hard disk. This enables the installation process to run a bit faster. Before copying the disc content to the hard disk, you must mount the disc. The following sections describe to mount disc and copy its content to the hard disk.

3.2.2.1 Mounting Discs

To mount a disc, follow these steps:

Switch user to root:
```
$ su - root
```
If necessary, enter a command similar to the following to unmount the currently mounted disc, then remove it from the drive:
```
# /usr/sbin/umount /cdrom
```
In this example, /cdrom is the mount point directory for the disc drive.
Insert the appropriate disc into the disc drive, then enter a command similar to the following to mount it:
```
# /usr/sbin/mount -t cdfs -o nodefperm,noversion /dev/disk/cdrom0c /cdrom
```
In this example, /cdrom is the disc mount point directory, which must exist, and /dev/disk/cdrom0c is the disc device name.
If Oracle Universal Installer is displaying the Disk Location dialog box, enter the disc mount point directory path, for example:
```
/cdrom
```

To continue, go to one of the following sections:

If you want to copy software to a hard disk, refer to the following section:

"Copying the Oracle Client Software to a Hard Disk"
If you want to install the software from the discs, refer to the "Installing the Oracle Client Software" section.

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 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 directory on the hard disk to hold the Oracle software:
```
$ mkdir OraCl10g
```
Change directory to the directory you created in step 1:
```
$ cd OraCl10g
```
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, refer to the "Mounting Discs" section 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 OraCl10g
```
In this example, /directory_path is the disc mount point directory, for example /dvd, or the path of the client directory on the DVD. The mount point directory is /dvd.
If necessary, mount the next disc and repeat step 5.

After you have copied all the required discs, refer to the "Installing the Oracle Client Software" section.
