3 System Requirements

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. Refer to the Oracle Database Installation Guide for Microsoft Windows (32-Bit) 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 the system.

Memory

For this release, 64 MB of real memory is the recommended minimum for running one instance of the gateway. Running additional instances of the Oracle Transparent 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 APPC connections opened by each user

• 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

Network Attachment

The hardware requires any network attachment supported by either Microsoft SNA Server for SNA communication or Microsoft Windows Sockets 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.

Disk Space

260 MB of disk space is required for installation.

Operating System

The Oracle Transparent Gateway for DRDA will run on the following operating systems:

• Microsoft Windows NT Server, version 4.0 (with Service Pack 6 or later)

• Microsoft Windows NT Workstation, version 4.0 (with Service Pack 6 or later)

• Microsoft Windows 2000 Server (with Service Pack 2 or later)

• Microsoft Windows 2000 Professional (with Service Pack 2 or later)

• Microsoft Windows 2003 Server

• Microsoft Windows XP Professional

Refer 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 system. The Oracle MetaLink Web site can be found at the following URL:

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

Communications

Supported SNA network software are:

• Microsoft SNA Server or Client, version 3.0 or version 4.0, or Host Integration Server, Version 5.0

• IBM Communications Server, Version 5.0 or 6.0

  
  

  Note: Version 5.0 requires the following patches: JR12583 (Super fix) JR12539 (individual Local LUs fix)

  
  

Oracle Database server

The Oracle Database server which is to act as the Oracle integrating server requires the latest released patch set for Oracle Database 10g server release 10.2, 10.1, 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 Pentium-based host and the Oracle integrating server.

The following Oracle networking products are required on the same system as the Oracle Database 10g server:

• Oracle Net Client 10.2.0.1.0

• an 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.
