System Requirements

This chapter describes the AS/400 hardware and software requirements for the Oracle Transparent Gateway for DB2/400.  It contains the following sections:

• Hardware Requirements

• Software Requirements

• Documentation Requirements

• Distribution Kit

Hardware Requirements

Processor

The gateway requires any AS/400 processor that supports a version of OS/400 that is currently supported by IBM.

Memory

For most installations, 5 MB of virtual memory is recommended to support each active user of the Oracle Transparent Gateway for DB2/400.

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

• 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

CD-ROM Drive

A CD-ROM drive is required.

Disk Space

As distributed, disk space of 640 MB is required for installation of this product.  Installation of further instances of the product at the same level use approximately 78 MB each.

These numbers are for initial conditions.  The disk space can be reduced by running the REMOVEOBS procedure (refer to "Step 5: Remove Observability").  After running REMOVEOBS, each gateway instance will use 58 MB, and the common objects (service programs and the National Language files) will use approximately 60 MB.

Software Requirements

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

Operating System Requirements

This gateway requires any current version of OS/400 that is supported (with maintenance) by IBM.

Oracle Integrating Server

The Oracle server that is to act as the Oracle integrating server requires the latest released patch set for Oracle9i server or Oracle8i server.

Documentation Requirements

In addition to the manuals supporting the Oracle Transparent Gateway for DB2/400, the Oracle Net and Oracle9i database server manuals are recommended.  You also need the appropriate AS/400 documentation for your system.

Distribution Kit

Before installing the gateway, verify that you have the correct CD-ROM and proper documentation:

• one Oracle Transparent Gateway for DB2/400 product CD-ROM

• appropriate Oracle documentation for installing, administering, and using the gateway: this book, Oracle Transparent Gateway for DB2/400 Installation and User's Guide

• Oracle9i database server
