Bugs Fixed

1.2.1 Release 3.0.0

Oracle REST Data Services release 3.0 includes the following new features and other changes:

- Changes to the Oracle REST Data Services Installer

- PL/SQL API for Creating RESTful Services

- OAuth 2.0 Client Credentials Grant Support

- RESTful Privileges Can be Mapped to URL Patterns

- Improved NoSQL Database Support

- RESTful Services Query Filtering Support

- Java API for Oracle REST Data Services Plugins

- "Developer's Guide" Material Now in Oracle REST Data Services Installation, Configuration, and Development Guide

- Apache JServ Protocol (AJP) Support Removed

- SQL Developer 4.1 Graphical Interface for Oracle REST Data Services

1.2.1.1 Changes to the Oracle REST Data Services Installer

You can now install Oracle REST Data Services with its own schema and define RESTful services.

You have options to run the installation in simple or advanced mode to prompt you for the information. The installation process is simple and fast.

The installer provides the option to migrate RESTful Service definitions stored in Application Express workspaces to Oracle REST Data Services-enabled schemas.

The installer provides an uninstall command; enter java -jar ords.war help uninstall for more information.

Oracle Application Express is no longer required for an Oracle REST Data Services installation. (It was required in Oracle REST Data Services releases 2.0.n.)

1.2.1.2 PL/SQL API for Creating RESTful Services

This release previews the PL/SQL API for creating and editing restful services using PL/SQL, enabling the creation and maintenance of RESTful services to be scripted via PL/SQL. The API also exposes all the OAuth 2.0 functionality, enabling OAuth Clients to be registered and managed. Note that this API is subject to change before the final release of 3.0.0.

1.2.1.3 OAuth 2.0 Client Credentials Grant Support

The OAuth 2.0 Client Credentials Grant type is now supported, enabling server to server authorization via OAuth 2.0, which is an important use case for enterprise applications.

1.2.1.4 RESTful Privileges Can be Mapped to URL Patterns

RESTful privileges can now be associated with arbitrary URL patterns, enabling RESTful privileges to protect any database resource accessed through Oracle REST Data Services, including JSON Collection store resources and AutoRest resources. Privilege to URL mappings can be configured using the PL/SQL API or using SQL Developer.

This and the preceding feature mean that JSON Collection store resources and AutoRest resources can now be protected by OAuth 2.0.

1.2.1.5 Improved NoSQL Database Support

The /store prefix on NoSQL Database resources has been eliminated, and support has been added for the new DDL capability introduced in NoSQL Database 3.2.5, enabling DDL statements to be issued through a RESTful endpoint.

1.2.1.6 RESTful Services Query Filtering Support

RESTful Services (that perform SQL queries) now support the specification of a JSON based filtering clause to further constrain the query. The filter clause can either be specified by including it as a parameter of the service's query string, or by submitting a POST request with the filter clause as the body of the POST request.

1.2.1.7 Java API for Oracle REST Data Services Plugins

A new Java API enables third parties to contribute extensions to the Oracle REST Data Services runtime. (Note that this API is subject to change before the final release of Oracle REST Data Services 3.0.0.) For more information, see the following under the location where you installed Oracle REST Data Services:

- Documentation: docs\javadoc\plugin-api

- Tutorial demonstrating how to compile and add a plugin: examples\plugins\plugin-demo

1.2.1.8 "Developer's Guide" Material Now in Oracle REST Data Services Installation, Configuration, and Development Guide

The Oracle REST Data Services Installation, Configuration, and Development Guide has been expanded to include material based on the old, unofficial "developer's guide" that was supplied as a file named restful_services_devguide.html.

The development material is now in the chapter titled "Developing Oracle REST Data Services Applications".

1.2.1.9 Apache JServ Protocol (AJP) Support Removed

Apache JServ Protocol (AJP) support has been removed because Jetty is now used as the run time for standalone mode, Jetty does not support AJP.

1.2.1.10 SQL Developer 4.1 Graphical Interface for Oracle REST Data Services

Oracle SQL Developer release 4.1 provides a graphical user interface and enables users to install Oracle REST Data Services and run it in standalone mode within SQL Developer. Within SQL Developer you can create, edit and validate RESTful services that are stored in Oracle REST Data Services schema.

For more information, see the topic "Oracle REST Data Services Administration and Development" in Oracle SQL Developer User's Guide or in the SQL Developer online help.

1.2.2 Release 3.0.1

See the readme.html file for detailed information about new features and other changes for this release. These include:

- Oracle 12c multitenant architecture support, which is explained in the new "Using the Multitenant Architecture with Oracle REST Data Services" appendix in Oracle REST Data Services Installation, Configuration, and Development Guide.

- A new "Getting Started with RESTful Services" appendix in Oracle REST Data Services Installation, Configuration, and Development Guide.

- Standalone mode document root for serving arbitrary static resources

- A new book, Oracle REST Data Services SODA for REST Developer's Guide.

- APEX_PUBLIC_USER and wwv_flow_epg_include_modules.authorize

1.2.8.1 APEX_PUBLIC_USER and wwv_flow_epg_include_modules.authorize

In line with security best practices and as recommended by Oracle Application Express Application Builder User's Guide when a database pool is configured to use the APEX_PUBLIC_USER, Oracle REST Data Services automatically sets the value of the security.requestValidationFunction setting to be:

WWV_FLOW_EPG_INCLUDE_MODULES.AUTHORIZE
This setting activates the white list of callable procedures that ships with Oracle Application Express and prohibits calls to other procedures. See the Oracle Application Express Application Builder User's Guide for more information about this procedure and how to customize its behavior.

1.5 Open Bugs and Known Issues

This section describes bugs and known issues for Oracle REST Data Services.

See also readme.html in the folder where you unzipped the Oracle REST Data Services installation kit for possible additional information about problems, fixes, and issues.

1.5.1 SODA

- Indexing of TIMESTAMP type does not work.

- HEAD responses incorrectly report 0 (zero) as the content length, and some also incorrectly report 204 (no content) as the status.

1.5.2 Application Express RESTful Service Migrations

- Migrating Application Express-based RESTful Services is not handling the case where a database does not contain any Application Express schema.It also does not handle the case where the installed version of Application Express is 5.0.0 or later. (Bug 21302877)

1.5.3 Autogenerated REST Endpoints

- AutoREST resources support the OAuth 2.0 Client Credentials flow only.

1.5.4 RESTful Services

- Application Express workspaces do not support first party authentication, and therefore do not support the /sign-in/ interactive sign-in form. Accessing /sign-in/ in Application Express workspaces will produce a 404 status.

1.5.5 NoSQL

- It is currently not possible to access secured NoSQL REST Endpoints with OAuth 2.0. Only first-party cookie authentication is supported.
