Audience

Oracle Database Net Services Reference is intended for network administrators who are responsible for configuring and administering network components.

To use this document, you need to be familiar with the networking concepts and configuration tasks described in Oracle Database Net Services Administrator's Guide.

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.

• Oracle Database Net Services Administrator's Guide

• Online Help for Net Services tools and utilities

• Oracle Database documentation set

A glossary of Net Services terms is available in the Oracle Net Services Administrator's Guide.

Many books in the documentation set use the sample schemas of the seed database, which is installed by default when you install Oracle. Refer to Oracle Database Sample Schemas for information on how these schemas were created and how you can use them yourself.
