At December the 1st, 2011, Oracle announced it’s new major release, the 12c release. As Oracle added the i (internet) at its 8 release, the g(gridcomputing) at its 10 release, now the focus will be on the c(cloudcomputing).
Many new features come out of the fact that Oracle has made its key application server ready for the cloud, that is, ready for to run on enigineered systems, in fact its own Exalogic machine, Oracle’s solution for implementing the cloud.
So let’s take a look what this new release brings us, in this blogpost. There are several new features available in the 12cNew or enhanced WebLogic 12c features
- JAVA EE 6 support all kinds of JEE6 specifications are implemented like :
- JSF 2.0,Java Servlets 3.0Â JPA 2.0 andÂ EJB 3.1.
- Managed Beans 1.0
- WebLogic 12c also supports supports Java SE 7 (and Java SE 6).
- Java language optimizations and Internationalization
- Client and server support
- SSL/TLS 1.2 in JSSE to support JAVA Socket Transport security
- Converged Java VM:JRockit and HotSpot are Â incorporated with the best features from both.The JVM convergence will be a multi-year process, which was confirmed during my presence at Oracle’s Publisher Seminar 2011 during
UKOUG 2011 is nearby and one of the coolest things in Oracle 11g and onwards is, IMHO, a functionality called XDB Repository Events. Most of you probably know that based on XMLDB functionality in the database, the database also can be used in a File server kind of way by enabling the XDB Repository HTTP/FTP or WebDav functionality via DBMS_XDB. XDB Repository Events are a kind of “triggers” that enable you to automatically trigger/do something based on the events triggered in this file/folder environment. For example, it is possible to automatically create duplicate files in the XDB Repository or secure them. Other possibilities are to read the content of such a file and insert that content, on the fly during the copy/paste action, into a relational table.
Most APEX enthousiast know of the PL/SQL Gateway, which is a small part of the functionality that is called the XDB Protocol Listener. Besides PL/SQL support, it also enables you to secure your data, as mentioned, trigger actions based, for example on MIME type, mount your database as a Logical Volume (currently only via WebDAV, eg. DAVFS) of your operating system. The XDB Protocol Listener can support your own solutions based More >
Last day of Oracle Open World and I am currently attending the last presentations. The first presentation, “Oracle XMLDB: A noSQL Approach to Managing all your Unstructured Data”, deals with the no-SQL approach and using Oracle XML DB in the context of using it with “Big Data”, that is unstructured data. The title of the presentation is “a bit” misleading due it reference to noSQL data handling. XML is mostly used in the area’s of structured, data centric, semi-structured an unstructured, that is document centric data. Due to the flexibility of XML, it can be used for bridging those data content forms. Via the XDB repository, xmltype storage and xmlindex, that content can be moved into the XML DB part of the Oracle database, mapped and categorized. You can use repository events to shred and filter this map while the data is going in regarding interfacing via FTP or WebDAV. In all the presentation addressed a lot of already known fact of the XMLDB functionality and not really how to use it with huge amounts of unstructured data.
I just made use of the very cool OTN Virtual Developer Day Database site. In this environment you can follow OTN Developer Day sessions, for example, at home, while making use of all the material available on that site plus the downloadable Virtualbox OTN Developer Day Appliance. Despite you can choose for tracks like Java, .Net, APEX, there is also a database section which handles (as you might expect it from me regarding interest) Oracle XMLDB functionality.
There is a 1 hour webcast available from Mark Drake, Oracle Product Manager, that takes you along all the basics / general overview (basic due too it is too extensive to show it in only an hour) of possibilities of Oracle XMLDB functionality. For convenience there is also a PDF document that has most of the slide info of the webcast. It doesn’t contain the demo’s or extra Virtualbox OTN Developer Day Appliance first steps info, of course, and what to do to reset the training XMLDB environment in this appliance.
This PDF and the webcast starts with the Oracle safeguard (legal disclaimer), with the general product outline slide saying among others that Oracle is not responsible or obliged to actually build-in features More >
Generate IDs in all components in ADF Faces pages and fragments – to facilitate automated Selenium based testing0
Lately, we have been introducing Selenium based testing for many our ADF Faces based web applications. Or rather, our testers created the tests for the web pages using Selenium. And did so quite successfully.
However, certain test scripts seemed to fall apart after having been run only a few times. That was rather annoying. Upon closer inspection, we noticed that the scripts that started failing had one thing in common: the Selenium scripts contained references to element id values that started with j_id. I realized that these id values are not defined in the pages by the developer, but instead assigned at run time by the ADF Faces framework. That in turn means that these ID values can easily change, between two test sessions using the same test script for example.
In order to have test scripts that continue functioning – it was required to have fixed id values. Besides, it is a best practice to assign id values to all components at design time rather than having them generated dynamically. Unfortunately, as found out later, we had over 2000 components lacking an id attribute with developer defined value. Going through all files and assigning ID values manually was not a task More >
