Performance tuning is one of the things that is often left behind during development. Project leaders and business owners seem to think it happens on its own or just push it to the background when the deadline comes close. Another thing that doesn’t help is that performance tuning for ADF applications is a more advanced topic. During a regular ADF training there’s so much to talk about there simply isn’t enough time to cover it, so people are left on their own to try and...

Render an unknown number of task flows in page or dashboard regions. Oracle Application Development Framework (Oracle ADF) regions display the contents of bounded task flows in designated areas on a page. Each region uses a special binding configuration—the task flow binding—in the Executables section of the parent page’s PageDef.xml file to populate the region content with data from the Oracle ADF binding layer. In use cases such as analytic dashboards, the contents of...

The “Key Exists” Validator is validator that can be defined at either the entity level or the attribute level but pertains to an entity object attribute to check whether a key exists based on a primary key, foreign key or an alternate key. The “Key Exists” validator will check first the cache querying rows not committed yet to the database and if the key is not found in the cache will run a check in the database.So let’s start by creating a new ADF Fusion Web Application...

On this subject, there are already many fine articles. I have borrowed from at least a dozen to understand what should happen and to make it work. You will find them listed under resources.It all started with me trying to have the UMS Adapter send an email. The setup of the email driver was done in EM FMW Control (see below) and I expected my email to be sent successfully. After a considerable and increasingly anxious wait at my mail client, I decided to check the log file...

WebLogic Server 12.1.3 provides support for selected new or updated APIs from Java EE 7, such as JAX-RS 2.0, Java API for JSON Processing (JSR 353), Java API for WebSocket (JSR 356), and JPA 2.1. These APIs and related capabilities simplify development of server applications accessed by "rich" clients using lightweight web-based protocols such as REST, WebSocket, and Server-Sent Events. Improvements to development tooling and open source support expand developer choices and...

Today at the Oracle Fusion Middleware Summer Camp in Lisboa I experiencedsome SIGSEGV JVM crashes. It happened when trying to use JDeveloper 12.1.3 under MacOS with the SOA Suite Development installer – right after the installation when starting up the server from within JDeveloper. (Most of the experienced SOA Suite developers went the beaten path using Windows). My installation used a fairly recent JDK 1.7_45, but SOA Suite 12c is supported on MAC OS only for a single user...

API Catalog (OAC) allows organizations to easily build a catalog of their APIs to provide visibility to those APIs for application development. OAC includes a simple metamodel for an API asset, automation to populate OAC with APIs, and the ability for users to search OAC for APIs and understand the details of the APIs to assess their fit in the users application.Powered by comprehensive automation capabilities, Oracle API catalog streamlines processes and optimizes reuse to...
