3 System Requirements

Hardware Requirements

The Hardware requirements includes processor, memory, network attachment, and drives.

Processors

Refer to the Oracle Database Installation Guide 10g for UNIX Systems and to the certification matrix on Oracle MetaLink for the most up-to-date list of certified hardware platforms and operating system version requirements to operate the gateway for your Linux, AIX-Based, HP-UX, or Solaris system. The Oracle MetaLink web site can be found at the following URL:

http://metalink.oracle.com/

The gateway processor requirements for your platform are as follows:

• For Linux 32-bit: Intel Pentium-based processors

• For Linux 64-bit: Intel Itanium 2 based 64-bit systems

• For Linux S/390: Any processor that can run Linux S/390

• For AIX-Based Systems: IBM pSeries

• For HP-UX: HP 9000 Series HP-UX that can run the required version of HP-UX

• For Solaris: A Solaris Operating System (SPARC 64-bit) that can run the required version of Solaris with 64-bit architecture

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 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 that is 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. If you want concurrent SNA access, then the hardware must support independent LUs. 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 are:

• Solaris (64-bit) requires 1.25 GB

• AIX 5L requires 1.4 GB

• HP-UX 11.0 (64-bit) requires 1.2 GB

• Linux (Intel 32-bit and 64-bit) requires 1 GB

• Linux for S/390 requires 1.2 GB

Software Requirements

The system software configuration that is described in this section is supported by Oracle 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

The operating systems that can be used are:

• Linux for Intel Pentium-based 32-bit systems

• Linux for Intel Itanium 2 based 64-bit systems

• Linux for S/390

• Solaris 5.8 or later

• AIX 5L

• HP-UX 11.0 (64-bit)

DRDA Databases

You must have at least one of the following DRDA servers at a supported release level:

• DB2/OS390

• DB2/VM

• DB2/400

• DB2/Universal Database

Communication Server

Supported SNA network software are:

• Solaris

  SNAP-IX, Version 7

• 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.

• Linux (32-bit)

  IBM Communications Server for Linux, Version 6.2.

Oracle Database

The Oracle Database which is to act as the Oracle integrating server requires the latest released patch set for Oracle Database 10g release 10.2.0, 10.1.0 or Oracle9i server release 9.2.

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 system as Oracle Database 10g:

• Oracle Net Client 10.2.0.1.0

• Oracle Adapter version 10.2.0.1.0

Oracle Net software is included in this Oracle Transparent Gateway for 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 DRDA distribution kit, the following Oracle documentation is recommended:

• Oracle Database Administrator's Guide

• Oracle Database Application Developer's Guide - Fundamentals

• Oracle Database Heterogeneous Connectivity Administrator's Guide

• Oracle Database Advanced Security Administrator's Guide

• Oracle C++ Call Interface Programmer's Guide

• Oracle Call Interface Programmer's Guide

• SQL*Plus User's Guide and Reference

• Oracle Database PL/SQL User's Guide and Reference

• Oracle Database SQL Reference

• Oracle Database Net Services Administrator's Guide

• Oracle Database Net Services Reference

In addition to the Oracle documentation, ensure that you have appropriate documentation for your platform, for your operating system, and 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.
