This blog contains tips and tricks on to how limit the JVM memory consumption of ADF applications. Like other web applications, Oracle ADF applications potentially use a lot of JVM memory. Many times, the root cause of a high memory usage is that application data retrieved from the database into memory is not properly bounded; too many rows are fetched and held in ADF BC memory. This can lead to memory over-consumption, very long running (more...)
Check out the new guide on SOA 11g Performance Tuning published July 2013 by Packt and written by Oracle Partner C2B2 Consulting Ltd:

From a first glimpse myself I have the following impressions:
- The book gives a very good overview of the various (more...)

Small point to note is that the zip file distribution has been (more...)
This summary shows step-by-step how to increase throughput and response time by doing this as an exercise with the AIA 11.2 O2C COMMS PIP.
AIA Tips & Tricks Series (2): Preventing from Exceptions with Very Large Audit Trails in AIA/SOA 11g
In very complex flows, audit trail or flow trace sizes can grow above the limit where EM console will display this correctly with the default settings. The reason is to prevent from generating huge audit trail objects in memory and thus potentially causing OOM errors – therefore the standard limit (more...)
Monitoring and optimizing BPEL Thread Pool utilization (and other metrics) is one of the key activities in performance tuning of BPEL/SOA based integrations. Although EM console provides some basic monitoring of the BPEL engine statistics, it is limited regarding the update interval, detail and the recording interval and cannot display (more...)
Just a word for anyone out there looking to use the Servlet 3.0 file upload feature with WLS 12c.
If you use the annotation approach on the Servlet class, it works perfectly well
However if you use the web.xml file to specify (more...)
That's quite the mouthful of annotations ..
The WebLogic Server 12c (126.96.36.199) documentation shows the prefer-application-packages and prefer-application-resources elements as being available in the weblogic.xml file.
To use prefer-application-packages in weblogic.xml, it looks like this:
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.2/weblogic-web-app.xsd"> <jsp-descriptor> <keepgenerated>true</keepgenerated> <debug>true</debug> </jsp-descriptor> <context-root>/quicktest</context-root> <container-descriptor> <prefer-application-packages> <package-name>org.codehaus.jackson.*</package-name> <package-name>org.codehaus.jettison.*</package-name> <package-name>org.objectweb.asm.*</package-name> </prefer-application-packages> </container-descriptor> </weblogic-web-app>
Which should offer no surprises really, EclipseLink rocks.
