Part Number E12512-01
Oracle Application Express is a hosted declarative development environment for developing and deploying database-centric Web applications. Oracle Application Express turns a single Oracle database into a shared service by enabling multiple workgroups to build and access applications as if they were running in separate databases.
Oracle Application Express Application Administration Guide describes how to perform administration tasks for an Oracle Application Express workspace, application, or an entire development instance.
This preface contains these topics:
This document contains the following chapters:
|Workspace and Application Administration||Describes how to perform Workspace administration tasks and access many of these reports.|
|Oracle Application Express Hosted Instance Administration||Describes tasks an Oracle Application Express administrator performs when administering an Oracle Application Express hosted instance.|
Oracle Application Express Administration Guide is intended for application developers who are building database-centric Web applications using Oracle Application Express. The guide describes how to use the Oracle Application Express development environment to build, debug, manage, and deploy applications.
To use this guide, you must have a general understanding of relational database concepts and an understanding of the operating system environment under which you are running Oracle Application Express.
Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. 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.

For information about Oracle error messages, see Oracle Database Error Messages. Oracle error message documentation is available only in HTML. If you have access to the Oracle Database Documentation Library, you can browse the error messages by range. Once you find the specific range, use your browser's "find in page" feature to locate the specific message. When connected to the Internet, you can search for a specific error message using the error message search feature of the Oracle online documentation.
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.
For additional application examples, please visit the Oracle by Examples (OBEs) Application Express page, located on Oracle's Technology Network. The OBEs provide step-by-step examples with screenshots on how to perform various tasks within Application Express.
