Oracle Procedural Gateway® for APPC Installation and Configuration Guide
10g Release 1 (10.1) for Microsoft Windows
Part No. B13694-01
The hardware requirements for this release of the gateway on Microsoft Windows are described in the following sections.
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:
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.
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.
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.
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.
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.

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".
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.
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:
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.
Important: For a list of known restrictions, be sure to read the "Known Restrictions" section before proceeding with installation of the gateway.
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:
PL/SQL User’s Guide and Reference
Oracle Database Installation Guide for Microsoft Windows
Oracle Database Administrator’s Reference
Oracle Database Concepts
Oracle Database Error Messages
Oracle Net Services Administrator’s Guide
Oracle Connectivity Guide
Oracle Call Interface Programmer’s Guide
In addition to your Oracle documentation, ensure that you have appropriate documentation for your platform, for your operating system and for your communications packages.
