# 4 Installing Oracle Transparent Gateway for Microsoft SQL Server

This chapter guides you through the installation procedure of Oracle Transparent Gateway for Microsoft SQL Server.

To install the Oracle Transparent Gateway for Microsoft SQL Server, follow these steps:

1. Ensure that the system meets all of the hardware and software requirements specified in "System Requirements for Oracle Transparent Gateway for Microsoft SQL Server" section .

2. Run the Oracle Universal Installer.

   See "Step Through the Oracle Universal Installer" section for more information on running the Oracle Universal Installer.

   Oracle Universal Installer is a menu-driven utility that guides you through the installation of the gateway by prompting you with action items. The action items and the sequence in which they appear depend on your platform.

   See Table 4-2 for description of the installation procedure of Oracle Transparent Gateway for Microsoft SQL Server.

3. Configure the Gateway.

   Refer to Oracle Transparent Gateway for Microsoft SQL Server Administrator's Guide for Microsoft Windows for a instruction about how to configure the gateway.

## 4.1 System Requirements for Oracle Transparent Gateway for Microsoft SQL Server

This section provides information about the hardware and software requirements for Oracle Transparent Gateway. It contains the following sections:

- "Hardware Requirements"

- "Software Requirements"

### 4.1.1 Hardware Requirements

Table 4-1 lists the system requirements for Oracle Transparent Gateways for Microsoft SQL Server, Sybase, and Teradata. Each Oracle Transparent Gateway has the same memory, networking, and disk space requirements.

Table 4-1 System Requirements for Oracle Transparent Gateways

Requirement | Value
--- | ---
Disk Space | 300 MB of additional disk space
Memory | 512 MB of real memory is recommended to support the gateway. The total real memory requirement for the concurrent use of the gateway also depends on these factors: The SQL statement processed by the user The number of cursors currently opened against Microsoft SQL, Sybase, or Teradata server The number of columns in the table being accessed
Oracle Networking | Oracle Net Services and Oracle Protocol Support for Named Pipes or TCP/IP must be installed on the Oracle Database computer and the gateway computer. The Oracle Net Services components are included on the Oracle Transparent Gateway installation media.
Processor | 550 MHz

#### 4.1.1.1 Checking the Hardware Requirements

To ensure that the system meets these requirements, follow these steps:

1. Determine the physical RAM size. For a computer using Windows 2000, for example, open System in the control panel and select the General tab. If the size of the physical RAM installed in the system is less than the required size, then you must install more memory before continuing.

2. Determine the size of the configured swap space (also known as paging file size). For a computer using Windows 2000, for example, open System in the control panel, select the Advanced tab, and click Performance Options.

   If necessary, then see your operating system documentation for information about how to configure additional swap space.

3. Determine the amount of free disk space on the system. For a computer using Windows 2000, for example, open My Computer, right-click the drive where the Oracle software is to be installed, and select Properties.

4. Determine the amount of disk space available in the `temp` directory. This is equivalent to the total amount of free disk space, minus what will be needed for the Oracle software to be installed.

   If there is less than 100 MB of disk space available in the `temp` directory, then first delete all unnecessary files. If the temp disk space is still less than 100 MB, then set the `TEMP` or `TMP` environment variable to point to a different hard drive. For a computer using Windows 2000, for example, open the System control panel, select the Advanced tab, and click Environment Variables.

### 4.1.2 Software Requirements

Oracle Transparent Gateways for Windows is supported on the following operating systems:

- Windows 2000 with service pack 1 or higher. All editions, including Terminal Services and Windows 2000 MultiLanguage Edition (MLE), are supported.

- Windows Server 2003

- Windows XP Professional

Windows Multilingual User Interface Pack is supported on Windows XP Professional and Windows Server 2003.

#### 4.1.2.1 Non-Oracle System Requirements

Oracle continually updates supported gateway configurations. For the latest supported configuration information, visit the OTN Web site:

## 4.2 Step Through the Oracle Universal Installer

Step Through the Oracle Universal Installer

Table 4-2 describes the installation procedure for Oracle Transparent Gateway for Microsoft SQL Server

Table 4-2 The Oracle Universal Installer: Steps for Installing the Gateway

Screen | Response
--- | ---
Oracle Universal Installer: Welcome | Click Next.
Oracle Universal Installer: File Locations | The Source section of the screen is where you specify the source location that the Oracle Universal Installer must use to install the Oracle Transparent Gateway. You need not edit the file specification in the Path field. The default setting for this field points to the installer file on your Oracle Transparent Gateway installation media. The Path field in the Destination section of the File Locations screen is where you specify the destination for your installation. You need not edit the path specification in the Path field. The default setting for this field points to `ORACLE_HOME`. After you set the fields in the File Locations screen as necessary, click Next to continue. After loading the necessary information from the installation, the Oracle Universal Installer displays the Available Products screen.
Oracle Universal Installer: Available Product Components | a. Deselect the checked products. b. Select Oracle Transparent Gateway 10.2.0.1.0, open up this row. c. Select Oracle Transparent Gateway for Microsoft SQL Server 10.2.0.1.0. d. Click Next.
Microsoft SQL Server and Database Names | Enter the name of the Microsoft SQL Server to which the gateway will connect in the Microsoft SQL Server field. Click Next to continue.
Oracle Universal Installer: Summary | The Installation Summary screen enables you to review a tree list of options and components for this installation. Click Install to display the Installation Status screen.
Oracle Net Configuration Assistant: Welcome | Click Cancel.
Oracle Net Configuration Assistant: | Click Yes.
Oracle Universal Installer: Configuration Tools | Click Exit.
Exit | The final screen of the Oracle Universal Installer is the End of Installation screen. Click Exit to exit the installer.

The gateway is now installed.

When the Oracle Universal Installer confirms that the installation is complete, verify that the installation procedure was successful. To do this, read the contents of the installation log file, which is located in the C:\Program Files\Oracle\Inventory\logs directory.

The default file name is InstallActionsYYYY-MM-DD_HH-mm-SS-AM/PM.log, where:

  YYYY is year
  MM is month
  DD is day
  HH is hour
  mm is minute
  SS is seconds
  AM/PM is daytime or evening

Each of these variables in the log file name represents the date and time the product was installed.
