Preface

This manual describes the Oracle Transparent Gateway for Ingres II, which enables Oracle client applications to access Ingres II data through Structured Query Language (SQL). The gateway, with the Oracle database server, creates the appearance that all data resides on a local Oracle database server, even though the data can be widely distributed.

This preface covers the following topics:

• Audience

• Documentation Accessibility

• Related Documents

• Conventions

Audience

This manual is intended for Oracle database administrators who perform the following tasks:

• Installing and configuring the Oracle Transparent Gateway for Ingres II

• Diagnosing gateway errors

• Using the gateway to access Ingres II data

  Note:

  You should understand the fundamentals of transparent gateways and the HP-UX operating system before using this guide to install or administer the gateway.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
