When you use SQLFire as a cache, you can configure a SQL data
loader that is triggered to load data from a backend repository on a miss in
SQLFire. When an incoming query request for a uniquely-identified row cannot be
satisfied by the distributed cache, the loader is invoked to (more...)
It is not uncommon for an ADF application to invoke DBTransactionImpl::postChanges()
to perform database DML without invoking commit (or rollback). This is typically done in environments where we also want to invoke PL/SQL logic in the database that already needs to see these pending changes.
The developer should make sure (more...)
asked me to review the book ‘Developing Web Applications with Oracle ADF Essentials
’ by Sten Vesterli
. The book isn’t a big bible, it’s 270 pages long and an easy read. Sten jumps onto the recently released ADF Essentials and takes you by the hand on how to (more...)
In this example we will show how we can determine which data format to return writing just a single controller method. In this example we either return XML or JSON and the system knows whether to convert to XML or JSON because of content negotiation. This example is based on the (more...)
JDeveloper comes with a nice audit framework, one of the great things about this framework is that you can write your own code to check for specific standards or fire specific rules you want to check. If you want to write extensions in 11g I recommend one off the two (more...)
In this post, I’d like to introduce 5 of the many new features Oracle 12C brings to us, database developer’s.
Of course this blog would be to long to explain them all in detail, so I will stick
to a small introduction.
- Generating a primary key without triggers, using nextval (more...)
Previously I have stated that there are some exceptions you would always want to keep an debugger breakpoint
on for. This help prevents code rotting away without you noticing - sometimes masking a different problem.
If you take this seriously then it is a good idea to extend this idea (more...)
I'm back since a few days already and needed to catch up with all the things which had been on hold for the last couple of days. It was the busiest time of the year for me. A complete week of JavaOne and OpenWorld in San Francisco. A very brief (more...)
As with many other high-level abstractions provided by the Spring projects, Spring Data GemFire provides a template that simplifies GemFire data access. The class provides several one-line methods, for common region operations but also the ability to execute code against the native GemFire API without having to deal with GemFire (more...)
You can execute data-independent functions or data-dependent functions
in vFabric GemFire. You run data-independent functions by targeting a specific
member or specific members in your distributed system, or by targeting logical
member groups on which to execute your function. If you are executing a
data-dependent function, you specify a region (more...)
Today, we are announcing the second public beta of Formspider Mobile (FS Mobile). This version brings us one step closer to our goal of enabling PL/SQL developers to build cross platform applications.
FS Mobile includes three new features:
Native iOS SupportFor the first time ever, FS Mobile enables PL/SQL (more...)
It has been a while that I did attend the JavaOne conference, but this year I am back. Yay!
During the conference I am giving two talks focusing on AeroGear and generally Mobile Development, that is powered by Java EE 7:
- Notify Your Mobile Clients by Integrating Push Networks (more...)
