DBA 2.0 – how options are really not optional or: "the infinite database"
After Web 2.0, Enterprise 2.0 and Wife 2.0, Oracle introduces the term DBA 2.0. It seems to refer to the DBA of the very near future. The one who can rely on a formidable pal hiding inside the database and taking on many of the boring, repeating tasks as well as advising on some of the tougher challenges when it comes to managing the database. Manageability is one of the focus areas for Oracle in the marketing strategy for the database as well as in the development budget allocation. Lots of time and energy are invested in making the database more manageable and striking the optimal balance between automated management and human decision making.
DBA 2.0 is perhaps also the guy about whom Mark Townsend,Vice President Product Management for Server Technologies, said: "to really screw a system up, you have to be a DBA!". To which he added: (more…)
OOW 2008 Preview: JHeadstart 11g – best practices, structure & consistency and even more extra productivity for ADF 11g
One of the theme songs for this year’s Oracle Open World undoubtedly will be ADF 11g. All by itself (Web 2.0) and as the glue for Enterprise 2.0 (WebCenter) and the foundation for Fusion Applications (ERP 2.0?, of which we hopefully will see the first real modules). And one of the singers of that song is Oracle ACE Steven Davelaar who will present the upcoming JHeadstart 11g release. Yesterday at our Oracle Open World 2008 preview, Steven rehearsed his performance, for some 30 interested attendees. Starting back in 2001, JHeadstart 11g follows on a long tradition of packaging best practices for using ADF, providing structure and catering for application wide consistency in page layout and adding to the already quite impressive productivity of developing ADF applications. ADF 11g is very powerful, especially in terms of visual (client) richness. JHeadstart helps to deal with that power, even if you are not already a very experienced ADF 11g developer. Steven hopes for a release of JHeadstart 11g around one to two months after ADF 11g is released, but cannot make any firm commitments (more…)
The world wide ADF community – convenes in the Oracle Wiki, develops the ADF methodology and meets at Oracle Open World
Oracle’s ADF framework is used by many organizations around the world. The largest of these obviously is Oracle’s own development team – of which thousands of developers have been trained in and are developing with ADF. Outside Oracle, again thousands of developers are creating advanced Web Applications using the ADF technology stack. Several dozens of these developers do not just develop with ADF, they investigate, extract best practices and try to share their experiences. They do that for example by participating in threads on OTN, presenting on various user group gatherings and conferences, publishing articles on their weblogs and pestering Oracle staff with their comments, criticism and suggestions. Thanks to the initiative of Oracle ACE Director Chris Muir, these ADF have joined forces. (more…)
ADF 11g: how events in one region cause other regions to refresh
One of the challenges in building Portal pages is to have events from one Portlet have the desired effect on other Portlets. For example when I select a location on a Map in one Portlet, other Portlets may need to be synchronized to show the weather, the best restaurants and the driving instructions for actually going there. The JSR-168 specification does not address this issue; the upcoming JSR-286 ("Portal 2.0") specs do. Working with ADF 11g, we have some fairly new mechanisms at our disposal, such as Task Flows and Regions, that allow us to construct pages (and applications) that are somewhat reminiscent of Portlets – or at least some of the interesting sides of Portlets in terms of creating relatively simple pieces of (stand-alone) functionality that can be wired together in a larger mashup – where ideally the mashup framework can provide event propagation between the stand alone pieces. In this article, I want to investigate how for example an event occuring in region A – based on a bounded taskflow – can be passed on to region B that is based on another bounded taskflow. (more…)
Dropping trees
There are many ways to reassign employees. You, as a programmer or DBA could, for instance, write an update statement to do that. But let’s say that you don’t want to lose your friends at the HR department. They want you to build a real flashy GUI to achieve the very same functionality. Ooops. No more lunch breaks for a week or two, because you planned this task to take only half an hour (the time that writing an update statement takes, if you type very slowly and test it intensively). ADF 11g provides you with two very handy features. First there’s the tree which is not new, but enhanced. Second there’s drag and drop functionality. Here is a way to use those two into a powerful combination. (more…)
