# 1 Oracle Transparent Gateway Overview

This chapter describes the installation of Oracle Transparent Gateways as well as issues that you should consider before installing the software. It includes the following topics:

- Gateway Installation Configurations

- Gateway Installation Methods

- Installation Considerations

- Upgrades

- Accessing the Installation Software

- Running the Oracle Universal Installer

## 1.1 Gateway Installation Configurations

You can install Oracle Transparent Gateway in either of the following configurations:

1. On the same computer as an existing Oracle Server but in a different Oracle home.

2. On a system with no Oracle Server.

3. On the same computer as the Oracle Server and in the same Oracle home directory. Note that in this case, the Oracle Server and the gateway must be at the same release level.

## 1.2 Gateway Installation Methods

You can choose different installation methods to install Oracle Transparent Gateways, as follows:

- Interactive Installation Methods

- Automated Installation Methods Using Response Files

### 1.2.1 Interactive Installation Methods

When you use the interactive method to install Oracle Transparent Gateways, Oracle Universal Installer displays a series of screens that enable you to specify all of the required information to install the Oracle Transparent Gateway software.

### 1.2.2 Automated Installation Methods Using Response Files

By creating a response file and specifying this file when you start Oracle Universal Installer, you can automate some or all of the Oracle Transparent Gateway installation.

For more information about these modes and about how to complete an installation using response files, refer to Appendix A.

## 1.3 Installation Considerations

This section contains information that you should consider before installing this product. It contains the following sections:

- Release Notes

- Hardware and Software Certification

- Multiple Oracle Homes

### 1.3.1 Release Notes

Read the release notes for the product before installing it. The release notes are available on the Oracle Database 10g Release 2 (10.2) installation media. The latest version of the release notes is also available on the Oracle Technology Network (OTN) Web site:

    http://www.oracle.com/technology/documentation/index.html

### 1.3.2 Hardware and Software Certification

The platform-specific hardware and software requirements included in this installation guide were current at the time this guide was published. However, because new platforms and operating system software versions might be certified after this guide is published, review the certification matrix on the OracleMetaLink Web site for the most up-to-date list of certified hardware platforms and operating system versions. The OracleMetaLink Web site is available at the following Web site:

`http://metalink.oracle.com`

If you do not have a current Oracle Support Services contract, then you can access the same information at the following Web site:

`http://www.oracle.com/technology/support/metalink/content.html`

### 1.3.3 Multiple Oracle Homes

This product supports multiple Oracle homes. This means that you can install this release or previous releases of the software more than once on the same system, in different Oracle home directories.

#### 1.3.3.1 Installing the Software on a System with an Existing Oracle Installation

You must install this product in a new Oracle home directory. You cannot install products from one release of Oracle Transparent Gateway into an Oracle home directory of a different release. For example, you cannot install release 10.1 software into an existing Oracle9i Oracle home directory. If you attempt to install this release in an Oracle home directory that contains software from an earlier Oracle release, then the installation will fail.

You can install this release more than once on the same system if each installation is installed in a separate Oracle home directory.

## 1.4 Upgrades

Upgrades are not supported for Oracle Transparent Gateways.

## 1.5 Accessing the Installation Software

You can access and install Oracle Transparent Gateway by using the following methods:

- Downloading Oracle Software from the Oracle Technology Network Web Site

- Copying the Oracle Transparent Gateway Software to a Hard Disk

### 1.5.1 Downloading Oracle Software from the Oracle Technology Network Web Site

You can download the installation files from the OTN and extract them to your hard disk.

To download the installation files:

1. Use any browser to access the OTN software download page:

       http://www.oracle.com/technology/software/index.html

2. Navigate to each of the download pages for the product that you want to install.

3. On each 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.

4. Select a file system with enough free space to store and expand the files. In most cases, the available disk space must be at least twice the size of each compressed file.

5. On the file system that you just selected, create a parent directory for each product that you plan to install, for example `Tg_1`, to hold the installation directories.

6. Download all the installation files to the directories that you just created.

7. Verify that the files that you downloaded are the same size as the corresponding files on OTN.

8. Extract the files in each directory that you just created.

9. After you have extracted the required installation files, go to the "Running the Oracle Universal Installer" section.

### 1.5.2 Copying the Oracle Transparent Gateway Software to a Hard Disk

Before installing Oracle Transparent Gateway, you might want to copy the software to the hard disk. This enables the installation process to run faster. Before copying the installation media content to the hard disk, you must mount the installation media.

To copy the contents of the installation media to a hard disk:

1. Create a directory on your hard drive. For example:

       d:\install\Disk1

2. Copy the contents of the installation media to the directory that you just created.

3. After you have copied all the required installation files, go to the "Running the Oracle Universal Installer" section .

## 1.6 Running the Oracle Universal Installer

In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer to install Oracle Transparent Gateway. However, you can also use Oracle Universal Installer to complete noninteractive installations, without using the GUI.

See Also: Refer to Appendix A, "Using Response Files for Noninteractive Installation" for information about noninteractive installations and other advanced installation topics

Start the Installer and install the software, as follows:

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

   If you are installing from a hard disk, then double-click `setup.exe` located in the directory you created for the downloaded or copied installation files.

2. When installing from the installation media, the Autorun screen automatically appears. If the Autorun screen does not appear, then:

   1. From the Start menu, select Run.

   2. Enter the following:

          DRIVE_LETTER:\autorun\autorun.exe

      In the Autorun screen, select Install/Deinstall Products.

3. Use the following guidelines to complete the installation:

   - Follow the instruction displayed in the Installer window. If you need additional information, click Help.

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

4. When you finish configuring, click Exit, then click Yes to exit from the Installer.
