Hardware Requirements

Table 4-1 lists the minimum hardware requirements for Oracle Database Gateway for Informix.

Table 4-1 Hardware Requirements for Oracle Database Gateway for Informix

Requirement	For Microsoft Windows (64-bit)
Total disk space	5 GB
Physical Memory	Minimum of 1 GB
Virtual memory	Double the amount of RAM
Video adapter	256 colors
Processor	AMD64, or Intel Extended memory (EM64T)

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.
