3 System Requirements

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.

3.2.1 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:

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.

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.
