3 System Requirements

This chapter describes the system requirements of the gateway. It contains the following sections:

3.1 Hardware Requirements

The hardware requirements for this release of the gateway on Microsoft Windows are described in the following sections.

3.1.1 Processor Requirements

Refer to the Oracle Database Installation Guide 10g Release 1 (10.1) for Microsoft Windows and to the certification matrix on the OracleMetaLink for the most up-to-date list of certified hardware platforms and operating system version requirements to operate the gateway for your system. The OracleMetaLink Web site can be found at:

http://metalink.oracle.com

The Oracle Procedural Gateway for APPC requires an Intel or 100% compatible personal computer based on a Pentium processor that can runMicrosoft Windows 2000 and higher.

3.1.2 Memory Requirements

For most installations, Oracle recommends a minimum of 256MB of real memory for the machine running the Oracle Procedural Gateway for APPC.

Each concurrent use of the gateway requires a minimum of 10MB.

The following factors affect the virtual memory requirements of the gateway server process:

  • number of concurrent gateway 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;

  • the Oracle Net protocol adapters that were included during the gateway installation.

3.1.3 CD-ROM Drive

A CD-ROM drive is required for installation of the software.

3.1.4 Disk Space Requirements

The gateway’s disk space requirements is a minimum of 300 MB.

3.2 Software Requirements

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

3.2.1 Operating System Requirements

Refer to the Oracle Database Installation Guide 10g Release 1 (10.1) for Microsoft Windows and to the certification matrix on the OracleMetaLink for the most up-to-date list of certified operating system version requirements to operate the gateway for your Windows Intel system. The OracleMetaLink Web site can be found at:

http://metalink.oracle.com

3.2.2 Communication Protocol Requirements

A Microsoft Host Integration Server 2000 is required, or IBM Communication Server V6.1.1 (or higher) for Windows. In this document, either of these communications servers will be referred to generically as SNA Server.


Note:

If you choose to use TCP/IP support for IMS Connect as your communications protocol, then you will not need to use an SNA Server. Your operating system comes with a TCP/IP protocol automatically installed. If you choose to use the TCP/IP protocol, you will need to configure it to work properly with the gateway; those instructions are located in Chapter 10, " Gateway Configuration Using TCP/IP Communication Protocol".

3.2.3 Oracle Server Requirements

The Microsoft Windows platform requires that the Oracle server which is to act as the Oracle Integrating Server be up to date with the latest patch set for supported Oracle database releases.

3.2.4 Oracle Networking Product Requirements

Oracle Net is automatically installed on the system where the Oracle Database 10g Server is installed and on the system where the gateway is installed. Refer to Chapter 5, " Configuring Your Oracle Network " in this guide for configuration information. Additionally, you may refer to the Oracle Net Services Administrator’s Guide.

3.2.5 IBM Mainframe Requirements

In addition to the other software requirements of the gateway and your particular platform, the following list outlines other requirements necessary on the IBM mainframe:


OLTP for SNA

The OLTP must support mapped APPC conversations. If the OLTP transaction programs to be executed through the gateway perform database updates, then the APPC verbs CONFIRM, CONFIRMED, and SEND_ERR must be supported by the OLTP. These verbs implement APPC sync level 1.

All resources controlled by an OLTP that can be updated by transaction programs invoked through the gateway must be defined as recoverable resources to the OLTP and host system if COMMIT/ROLLBACK capability is required for those resources. For example, a VSAM file updated by a CICS transaction must be defined to CICS as a recoverable file for COMMIT/ROLLBACK to control the updates.

The gateway is compatible with all supported releases of SNA-enabled products such as CICS, IMS/TM, IDMS and z/OS.

Important: For a list of known restrictions, be sure to read the "Known Restrictions" section before proceeding with installation of the gateway.


OLTP for TCP/IP

IMS/TM: Release 7.1 or later is required, as well as any APARs (patches) listed in the IBM IMS Connect Guide and Reference.

IMS Connect: Release 1.2 or higher is required.

3.3 Documentation Requirements

Oracle recommends that you become familiar with the concepts and components of all products related to your gateway and that you read the following documentation on Oracle products other than your gateway:

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

The following IBM documentation may be useful:

The title of the IBM publication was accurate at the time of the publication of this guide. Titles and structure of these documents are subject to change. For other operating system, SNA communication package and TCP/IP package references, refer to the appropriate vendor documentation for your system.
