ADF Mobile : Device Interaction API – Pictures, GPS and Email With Attachments by Luc Bors

During the AMIS ADF Masterclass I showed how to take a picture from within an ADF Mobile application, attach it to an Email and send that email out to several recipients. To top it of, I even added the GPS coordinates to the subject, so you know where the picture was taken. And all of that with the push of one single button. Sounds complicated ? Well actually it is very simple.
There are two ways to interact with device services. One is by using the page Definition, the second is by using the API.

I decided not to use the (more...)

Patching Oracle Exalogic – updating Linux on the compute nodes part I by Jos Nijhoff

Patching Exalogic part 4a
Before we dive further into the brave new world of virtualization on the Exalogic, I thought I’d finish up my series of posts on patching. My previous posts on this subject detailed upgrading firstly the network compontents (Infiniband Gateway Switches, indicated in green) and secondly the storage component (ZFS 7320 appliance, in blue).

This post will deal with patching the operating system on the modified Sun Fire X4170 M2 servers (in red), dubbed compute nodes in Exalogic terminology. In our case the OS is Oracle Linux.

As before with the storage and (more...)

Data Source Connection Pool Sizing by Steve Felts

One of the most time-consuming procedures of a database application is establishing a connection. The connection pooling of the data source can be used to minimize this overhead. That argues for using the data source instead of accessing the database driver directly.

Configuring the size of the pool in the data source is somewhere between an art and science - this article will try to move it closer to science.

From the beginning, WLS data source has had an initial capacity and a maximum capacity configuration values. When the system starts up and when it shrinks, initial capacity is used. (more...)

Redirecting JVM Output

The JVM in which a WebLogic Server instance runs, sends messages to standard error and standard out. Server as well as application code write directly to these streams instead of using the logging mechanism. Through a configuration option, you can redirect the JVM output to all the registered log destinations, like the server terminal console and log file. When enabled, a log entry appears as a message of NOTICE severity. Redirecting the JVM output does not capture output from native code, for example thread dumps from the JVM.
For example, to redirect the JVM standard out messages:

Coherence and WebLogic by René van Wijk

In this post, we configure WebLogic and an in-memory data grid, such as Coherence and present scripts to start and stop the environment. We start with creating a Coherence Server (which will be our storage enabled node in the cluster). You can find the steps required to create a Coherence Server here.René van Wijk

When the server is created, click on the created server and subsequently on the server start, configuration tab, in order to set the class path and some JVM parameters.

Enter the following properties:

  • Java Home: Specify the location of the JDK installation directory such that /bin/java exists, in (more...)
