OOW2011 - Announcing Oracle`s Big Data Appliance

By
During the Oracle ACE Director briefing, Mark Townsend, VP Database Product Management, did "State of the Union" on the Oracle database. This post is my report of his talk...
At this moment around 55% of the installed base of the Oracle database is on 11.2. Last year, Oracle made more money from selling more database licenses and more options on existing installations.
Mark mentioned that there are customers with 1,000`s of databases (and even one with 80,000!) - all using different versions of the database, of the operating system, storage etc. This situation is very hard to maintain and to keep up and running. Inn Oracle`s view, consolidation into a "private cloud" is the solution, and therefore Oracle offers Exadata. One (or less) databases are easier to secure, easier to make high available and easier to upgrade. And when you use Oracle software troughout your application stack, why not use Oracle hardware as well? So Oracle is striving towards a "red stack" (i.e. all Oracle).

The latest version of the Oracle database is 11.2.0.3. 11.2.0.4 is planned for somewhere next year. After that, Oracle 12 will replace the "g" with a "c" - for "cloud" of course! - and should be available somewhere next year as well. Oracle 12c is not a subject on this OpenWorld. You can sign up for the beta test, which will start in November.
Last week, the Oracle Database Appliance (ODA) was announced. The ODA comes with standard 24 cores, but you can license per core - completely different from the current licensing where you have to pay for all cores that are available in your hardware. In Oracle`s terminology, an "Appliance" is engineered for simplicity, anything called "Exa-whatever" is engineered for speed. Next to the ODA, Oracle announced this Monday the "Big Data Appliance", using a (new) Oracle NoSQL database (based on the Berkeley DB). This appliance will do massively parallel batch processing with Hadoop. Therefore Oracle will distribute Hadoop (and support it as well). There will be an Oracle Data Integrator (ODI) to get the data from Hadoop into a relational Oracle database. Another new product in this appliance is "Oracle R". "R" is open source replacement for SAS - a statistical tool for data-analysts (like the software used by the female computer wizard in the tv-series Criminal Minds). So the BDA consists of this whole stack (as I understood it). The BDA solution (or framework or architecture) is aimed at processing huge bulks of no-SQL data (key-value pairs), like user clicks on website, phone calls etc, but is good for oldfashioned ETL too!

Fix Interactive Report headers issue when using a Region Display Selector

By
When you have multiple Interactive Reports (IR) on your page and use a Region Display Selector to mimic tabs, you might notice some weird behaviour in the IR headings if you switch tabs. The headings are not positioned correctly and you get an extra empty row under the headings. It just looks weird and ugly. But if you resize your browser window, it all looks fine again (until you switch to another tab..) So can we fix this by creating a Dynamic Action that mimics that "browser window resize" event? Yes we can! Create a Dynamic Action that fires on Click of the jQuery selector li.apex-rds-item a . That should fire a JavaScript snippet :  apex.event.trigger(this.triggeringElement, "apexwindowresized"); So now a click on a tab not only switches from one IR to another but also fires that event that will "autofix" the IR headers. A simple solution for an annoying problem. This applies to APEX 5.0, I assume it will be solved in 5.1.

How to create neatly formatted Excel documents using PL/SQL?

By
If there is a requirement to produce output from an application into Excel, you would probably create a CSV (Comma Separated File) with the data and start Excel to show the data - at least that's what I did...until now. The drawback of this solution is that you could only produce data and no nice layout. But Excel is also capable of opening HTML-files and using this you could create Excel files with data and magnificent layout! Let me give an example: 1. Create a procedure to show the data in formatted in an HTML table. CREATE OR REPLACE PROCEDURE display_emp_list IS v_emp_count NUMBER(5); v_empno NUMBER(8); v_ename VARCHAR2(50); v_job emp.job%TYPE; v_sal emp.sal%TYPE; v_bg_color VARCHAR2(10) := ''; CURSOR c_emp IS SELECT empno, initcap(ename), job, sal FROM emp ORDER BY ename; BEGIN SELECT COUNT(*) INTO v_emp_count FROM emp; owa_util.mime_header('application/ms-excel', FALSE); htp.p('Content...

Refresh selected row(s) in an Interactive Grid

By
In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid . The use case I'll cover right here is probably more common - and therefore more useful! Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user. The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even wors...
