12 Installing Oracle Database Gateway for DRDA

This chapter guides you through the installation procedure of Oracle Database Gateway for DRDA.

To install the gateway, follow these steps:

  1. Ensure that the system meets all of the hardware and software requirements specified in "System Requirements for Oracle Database Gateway for DRDA" .

  2. Log on to your host computer as a member of the Administrators group.

  3. Run the Oracle Universal Installer.

    See "Step Through the Oracle Universal Installer" section for more information about 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 12-2 for a description of the installation procedure of Oracle Database Gateway for DRDA.

System Requirements for Oracle Database Gateway for DRDA

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

Hardware Requirements

Table 12-1 lists the minimum hardware requirements for Oracle Database Gateway for DRDA.

Table 12-1 Hardware Requirements for Oracle Database Gateway for DRDA

Requirement Value

Disk space for Oracle home

800 MB

Disk space for system drive (SYSTEM_DRIVE:\)

260 MB

Temporary disk space

125 MB

Physical Memory

64 MB of real memory is the recommended minimum for running one instance of the gateway. Running additional instances of the Oracle Database Gateway for DRDA might require additional real memory or increased swap space to achieve reasonable performance.

The total real memory requirement for each concurrent use of the gateway depends on the following factors:

  • Number of concurrent TCP/IP connections opened by each user

  • Number of data items being transferred between the gateway and the remote transaction program

  • Additional factors such as configured network buffer size

Processor

This gateway requires a host with an Intel or 100% compatible PC with a Pentium-based processor that can run the required version of Microsoft Windows.


Checking the Hardware Requirements

To ensure that the system meets the minimum 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 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 Windows 2000, for example, open the System control panel, select the Advanced tab, and click Environment Variables.

Software Requirements
