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...)
I love the zip file distribution. It's the flavour of WLS I mostly use. Unzip, configure, go. Delete it to remove it, start all over again. Install it from a Maven goal. Easy.
Small point to note is that the zip file
distribution has been (more...)
Was talking to one of our local partners yesterday who's in the middle of an infrastructure build for FMW using a 3rd party cloud provider. He mentioned he was looking at how to handle the JTA transaction logs for their HA requirements without being able to rely on shared (more...)
First of all, shutdown your domain (in this example, my domain is called ‘oldDomain’ and has one Managed Server): export MW_HOME=/u01/app/oracle/middleware export WLS_HOME=$MW_HOME/wls_10.3.6 export DOMAIN_NAME=oldDomain export DOMAIN_HOME=$MW_HOME/user_projects/domains/$DOMAIN_NAME $DOMAIN_HOME/bin/stopWebLogic.sh $DOMAIN_HOME/bin/stopManagedWebLogic.sh ManagedServer_1 Remove the domain entry from the Node Manager file: vi $WLS_HOME/common/nodemanager/nodemanager.domains …remove this line: oldDomain=/u01/app/oracle/middleware/user_projects/domains/oldDomain (more...)
The Oracle APEX Listener is a Java based alternative to using Oracle HTTP Server (OHS) with mod_plsql. In the past I’ve installed early versions of APEX 3 using this configuration, then later on started using EPG (Embedded PL/SQL Gateway) which worked fairly well. Recently however, I decided to try using the latest APEX (more...)
The Oracle A-Team has published a new AIA 11g performance tuning whitepaper – see
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.
We've been busy working on putting in support for the WebSocket Protocol into WebLogic Server with the intent to include it in the next major release (usual caveats apply with respect to dates, times, features, etc.). Running the Autobahn WS Testsuite
, which seems to be the industry (more...)
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...)
In a similar vein to my last post, with this blog I'd like to try and raise the visibility of another bug that is being seen in a few different places, and for which there is already a patch available for it.
The basic issue here is that when an (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...)
Multipart File Upload with WLS 12c
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 ..
was posed recently on the WLS EJB OTN
forum asking about why WLS doesn't correctly support this combination of annotations, where the method with the @PostConstruct annotation was not being called as expected.
WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. The singleton can be migrated to another server in the cluster, either automatically (more...)
The OTN documentation pages don't appear yet to have a link to the WLS 10.3.6 documentation set.
If you are looking for it in the interim you can find it here:
While this is predominantly a patchset, there are a number of new features (more...)
Following a posting on here last year that described using the filtering classloader within a web application, several folks commented that it wasn't described in the documentation.
The WebLogic Server 12c (184.108.40.206)
documentation shows the prefer-application-packages and prefer-application-resources elements as being available in the weblogic.xml file.
Short and sweet this one, purely for my own future simple reference.
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">
Talking with Doug Clarke
of EclipseLink fame and fortune last week, it sounds like there is some real interest from developers in wanting to update WebLogic Server to use later versions of the EclipseLink in order to access it's evolving feature set.
Which should offer no surprises really, EclipseLink rocks.
