System Requirements

This chapter provides information about hardware and software requirements that is specific to this release of the Oracle Transparent Gateway for IBM DRDA.  It includes the following sections:

• Hardware Requirements

• Software Requirements

• Documentation Requirements

Hardware Requirements

Processor

This gateway requires an RS/6000 host processor capable of running 64-bit applications.

Memory

For most installations, 3M of real memory is recommended for the first user to support the Oracle Transparent Gateway for IBM DRDA.  Estimated memory requirement for each concurrent use of the gateways is 1M.

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

• Number of concurrent APPC connections open by each user

• Number of concurrent TCP/IP connections open 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

Network Attachment

The hardware requires any network attachment supported by either SNA server networking for SNA communication, or AIX TCP/IP Networking Facility for TCP/IP communication.  The network attachment for SNA is typically a Token Ring or SDLC Coaxial attachment.  The hardware must support independent LUs if you want concurrent SNA access.  The network attachment for TCP/IP is typically an Ethernet attachment.

CD-ROM Drive

An internal or external CD-ROM drive is required for installation.

Disk Space

400M of disk space is required for installation, or 1G for a stand-alone installation.

Software Requirements

The system software configuration described in these requirements is supported by Oracle Corporation as long as the underlying system software products are supported by their respective vendors.  Verify the latest support status with your system software vendors.

Operating System

AIX 4.3.3 is required.

DRDA Databases

You must have at least one of the following IBM DRDA databases at a release level supported by IBM:

• DB2/MVS

• DB2/VM

• DB2 Server

• DB2/400

• DB2/Universal Database

Communications

IBM Communications Server for AIX (SNA server) version 6.0 (64-bit capable) is required.

Oracle Server

The following Oracle server is required to act as the integrating Oracle Server:

Oracle9i Server Release 9.0.1.1.0 (which includes HS patch 1819588).

Oracle Networking Products

If the integrating Oracle Server is not on the same RS/6000 host as the gateway, then Oracle Net is required to support communication between the RS/6000 host and the integrating Oracle Server.

The following Oracle networking products are required:

On the same machine as the Oracle 9i Server:

• Oracle Net Client 9.0.1.0.0

• an Oracle Adapter version 9.0.1.0.0

Oracle Net software is included in this release of Oracle Transparent Gateway for IBM DRDA.  Your gateway license includes a license for Oracle Net and an adapter of your choice.  This license restricts the use of Oracle Net for gateway access.

Documentation Requirements

In addition to the documentation provided with the Oracle Transparent Gateway for IBM DRDA distribution kit, the following Oracle documentation is recommended:

• Oracle9i Administrator's Guide

• Oracle9i Application Developer's Guide

• Oracle9i Heterogeneous Services

• Oracle9i Error Messages

• Oracle SNMP Support Reference Guide

• Programmer's Guide to the Oracle Precompilers

• Programmer's Guide to the Oracle Call Interface

• SQL*Plus User's Guide and Reference

• Oracle Net documentation for RS/6000

• Oracle Net Administrator's Guide

In addition to your Oracle documentation, ensure that you have appropriate documentation for your platform (RS/6000), for your operating system (AIX) and for your DRDA server (DB2/MVS, DB2/400, DB2 Universal Database, DB2 server, or DB2 server for VM).

The following IBM publications might also be useful:

• Distributed Relational Database: Connectivity Concepts and Scenarios

• Distributed Relational Database: Every Manager's Guide

• Distributed Relational Database Architecture: Problem Determination Guide

The titles of the IBM publications are accurate at the time of printing of this guide.  Titles and structure of these publications are subject to change.
