6 Installing Oracle Database Gateway for Teradata

This chapter provides information about the hardware and software requirements and the installation procedure for Oracle Database Gateway for Teradata.

To install the gateway, follow these steps:

Ensure that the system meets all of the hardware and software requirements specified in "System Requirements for Oracle Database Gateway for Teradata" section.
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 6-2 for a description of the installation procedure of Oracle Database Gateway for Teradata.

6.1 System Requirements for Oracle Database Gateway for Teradata

This chapter provides information about the hardware and software requirements for the gateway. It contains the following sections:

"Hardware Requirements"
"Software Requirements"

6.1.1 Hardware Requirements

Table 6-1 lists the minimum hardware requirements for Oracle Database Gateway for Teradata.

Table 6-1 Hardware Requirements for Oracle Database Gateway for Teradata

Requirement	For Microsoft Windows (32-bit)	For Microsoft Windows (64-bit)
Total disk space	4 GB	5 GB
Physical Memory	1 GB 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 Teradata The number of columns in the table being accessed	Minimum of 1 GB
Virtual memory	Double the amount of RAM	Double the amount of RAM
Video adapter	256 colors	256 colors
Processor	550 MHz minimum(On Microsoft Windows Vista, 800 MHz minimum)	AMD64, or Intel Extended memory (EM64T)

6.1.1.1 Checking the Hardware Requirements

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

Determine the physical RAM size. For a computer using Microsoft 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.
Determine the size of the configured swap space (also known as paging file size). For a computer using Microsoft 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.
Determine the amount of free disk space on the system. For a computer using Microsoft Windows 2000, for example, open My Computer, right-click the drive where the Oracle software is to be installed, and select Properties.
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 125 MB of disk space available in the temp directory, then first delete all unnecessary files. If the temp disk space is still less than 125 MB, then set the TEMP or TMP environment variable to point to a different hard drive. For a computer using Microsoft Windows 2000, for example, open the System control panel, select the Advanced tab, and click Environment Variables.
