OOW2011 - Announcing Oracle`s Big Data Appliance

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!

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

APEX 5 New Static File Features

In APEX 4 you could upload files - like CSS files, JavaScript files, Images and whatever else you like - into the APEX Repository. When you navigate to Shared Components, there is a Files section that offers three different options:
CSS Files are always uploaded (and changed !) for the whole Workspace. For Images and Static Files (usually JavaScript) you could choose whether they should be available for the whole Workspace or for a specific Application only. And if you had a lot of files - e.g. a lot of images - then you had to go through the upload process one-by-one. But that's usually a one time only thing. If you make changes to the CSS and JavaScript files - and that's a continuous process in development - then you had to delete the existing file and upload the new one. Over and over again. And meanwhile fighting the cache of the webserver and your browser.  And another irritating issue: You couldn't use relative references in your CSS or JavaScript files as they just…

Using LDAP for Authentication and Authorization within APEX

One of my current customers would like to use their LDAP (Microsoft Active Directory) server for authentication and authorization of APEX applications. Of course we tried to set up a standard LDAP Authenication that's available within APEX. But we couldn't get that to work. Maybe it has to do with the fact that the client stored their Users within Groups within Groups within .... . Or maybe it doesn't do a full tree walk in the directory. Or maybe it is just because it is Microsoft - and not Oracle Internet Directory (OID). So we moved to a custom Authentication using the DBMS_LDAP functions (and some examples from the Pro Oracle Application Express book and Tim Hall - a.k.a. Oracle Base).

One of the issues we encountered that we wanted to use the user's login name, like "jdoe" and not his full name ("John Doe"). And the login name is stored in the "sAMAccountName" attribute. But authenticating using just "jdoe" didn't work. …
