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

Includes processor, memory, network attachment, and drives

Processor

This gateway requires a host with or without multiple processors that is capable of running the required version of the operating system.

The UNIX platforms supported by this gateway release are: Sun Solaris Operating System (SPARC), IBM RS/6000 AIX-based system, Hewlett-Packard 9000 Series 700 or 800, Linux/390 running on S/390 hardware.

Memory

For most installations, a minimum of 256 MB of real memory is recommended for the first user to support the Oracle Transparent Gateway for IBM DRDA.

The total real memory requirement for each concurrent use of the gateway 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 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

Disk space required for installation:

Solaris requires 550 MB

AIX requires 1.1 GB

HP-UX requires 550 MB

Linux/390 requires 550 MB

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

• Solaris 2.6 or later

• AIX 4.3.3 or AIX 5L

• HP-UX 11.0 (64-bit)

• Linux/390: SuSE SLES-7 (S390) with Kernel 2.4.7 and Glibc 2.2.4

DRDA Databases

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

• DB2/OS390

• DB2/VM

• DB2/400

• DB2/Universal Database

Communication Server

The operating systems utilize specific communications servers.

Solaris

Sunlink SNA Peer-to-Peer Communications Server, Version 9

SNAP-IX, Version 6

AIX

IBM Communications Server for AIX, Version 6.0

HP

HPUX SNAPlus2 Link Release 11.x and HPUX SNAPlus2 API Release 11.x or higher are required.

Oracle Server

The Oracle server which is to act as the Oracle integrating server requires the latest released patch set for Oracle9i server release 9.2 or release 9.0.1, or Oracle8i server release 8.1.7.

Oracle Networking Products

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

The following Oracle networking products are required:

On the same machine as the Oracle9i Server:

• Oracle Net Client 9.2.0.1.0

• an Oracle Adapter version 9.2.0.1.0

Oracle Net software is included in this Oracle Transparent Gateway for IBM DRDA release.  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 Database Administrator's Guide

• Oracle9i Application Developer's Guide - Fundamentals

• Oracle9i Heterogeneous Connectivity Administrator's Guide

• Oracle9i Database Error Messages

• Oracle C++ Call Interface Programmer's Guide

• Oracle Call Interface Programmer's Guide

• SQL*Plus User's Guide and Reference

• Oracle9i SQL Reference

• Oracle9i Net Services Administrator's Guide

• Oracle9i Net Services Reference Guide

In addition to your Oracle documentation, ensure that you have appropriate documentation for your platform, for your operating system (OS), and for your DRDA server (DB2/OS390, DB2/400, DB2 Universal Database, or DB2 server for VM).

The IBM publications regarding a distributed relational database might also be useful.
