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!

apex_application.g_f0x array processing in Oracle 12

By
If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one: then you disable the " Escape special characters " property and the result is an updatable multirecord form. That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. All the columns are submitted as separated arrays, named apex_application.g_f0x - where the "x" is the value of the "p_idx" parameter you specified in the apex_item calls. So we have apex_application.g_f01, g_f02 and g_f03. But then you discover APEX has the oddity that the "checkbox" array only contains values for the checked rows. Thus if you just check "Jones", the length of g_f02 is 1 and it contains only the empno of Jones - while the other two arrays will contain all (14) rows. So for ...

Filtering in the APEX Interactive Grid

By
Remember Oracle Forms? One of the nice features of Forms was the use of GLOBAL items. More or less comparable to Application Items in APEX. These GLOBALS where often used to pre-query data. For example you queried Employee 200 in Form A, then opened Form B and on opening that Form the Employee field is filled with that (GLOBAL) value of 200 and the query was executed. So without additional keys strokes or entering data, when switching to another Form a user would immediately see the data in the same context. And they loved that. In APEX you can create a similar experience using Application Items (or an Item on the Global Page) for Classic Reports (by setting a Default Value to a Search Item) and Interactive Reports (using the  APEX_IR.ADD_FILTER  procedure). But what about the Interactive Grid? There is no APEX_IG package ... so the first thing we have to figure out is how can we set a filter programmatically? Start with creating an Interactive Grid based upon the good o...

Stop using validations for checking constraints !

By
 If you run your APEX application - like a Form based on the EMP table - and test if you can change the value of Department to something else then the standard values of 10, 20, 30 or 40, you'll get a nice error message like this: But it isn't really nice, is it? So what do a lot of developers do? They create a validation (just) in order to show a nicer, better worded, error message like "This is not a valid department".  And what you then just did is writing code twice : Once in the database as a (foreign key) check constraint and once as a sql statement in your validation. And we all know : writing code twice is usually not a good idea - and executing the same query twice is not enhancing your performance! So how can we transform that ugly error message into something nice? By combining two APEX features: the Error Handling Function and the Text Messages! Start with copying the example of an Error Handling Function from the APEX documentation. Create this function ...
