Everything that is not part of the final application
When you have many development servers or cloud servers which runs Oracle software and then you know that configuration management of those servers is very important and must be repeatable. When you configure and install all that software by hand, then you also know that the chance is high that those servers are not exactly the same. This can lead to many configuration issues, tons of documentation pages and days for a new environment is released.
With Puppet of puppetlabs you can automate installations and configuration of all these servers and check the status or read the configuration of the servers. Puppet is open source and it works perfectly with VMware or cloud providers like amazon. There is also Puppet Enterprise which is free up to 10 nodes.
If you want to learn Puppet you can follow this guide and download the puppet test VirtualBox or VMware image.
On github I made a puppet wls module which can retrieve all the Oracle WebLogic software, domains + weblogic artifacts, running nodemanager + weblogic servers data and displays these values as facts in the Puppet Dashboard.
Second part of the puppet module are scripts to automatically install the followingMore >

That depends on who you ask. Some people primarily will have taken goodies from the exhibition floors with them while other may have focused on less tangible goods and gone for inspiration and vision. After the heyday (2006/2007), some waning years and the robust recovery (2011) after an initially tentative turn around (2010) this year seems to have been one of consolidation and careful further evolution. Some choices have been made – not all of them popular but most apparently sensible and reliable because backed by commercial sense.
While the double entendre of ‘SUNday’ no longer exists, this first day is still an important day. To set the stage, manage expectations, build on the atmosphere and layout the roadmap (starting that sometimes not even subtle massaging of the minds). The keynote sessions are the key events that define scope and themes for the conference.
Java is very much on the move again. After the virtual stand still just before and for a while after Oracle took over (from) Sun, last year saw a dramatic increase in the Java movement. This year that thread continues. Not with many spectacular announcement, but with a solid pursuit of earlier roadmaps and an apparently good collaboration between vendors in the Java space. The one big elephant in the room – that is actually not in the room at JavaOne – is Google. Otherwise for example, Oracle staff happily shared the stage for this keynote session with IBM.
This year’s overall slogan for JavaOne is: Make the future Java.
It is very much an invitation from Oracle to help bring the Java platform forward. In many ways: ideas, feedback, testing, propagating, creating code, joining JSR committees etc. Oracle and other vendors More >
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
Table filtering, aka Query by example, is a great feature of ADF tables. This feature provides filterboxes on top of a column(es).
and filters the data based on the values in the filterbox:
This works like a charm on an Oracle database, but when you use MySQL the filtering doesn’t work and actually doesn’t retrieve any data at all. As you can understand, this is not expected and definitely not wanted behaviour.
The first step in solving this behaviour was to enable logging (either via the weblogic diagnostic console or by adding -Djbo.debugoutput=console to the Java Options in the project properties Run configuration). In the log console we see that the SQL statement for this table collection / ViewObject now includes a where clause that includes the table filter value(s): ‘WHERE ( ( (EmployeesEo.FIRST_NAME LIKE ( :vc_temp_1 || ‘%’) ) ) )‘. This where clause with the % appended to the variable is automatically performed by the ADF framework.
As it turned out, this concatenation of the value with the % (:vc_temp || ‘%’) was the cause of our problem. This concatenation with a double pipe is a SQL92 standard. However with MySQL the concatenation is done with the concat function More >
