I'm about to embark on a journey that explores the use of WebLogic Server within a DevOps regime. My first port of call for this journey will be using Chef.
A loose travel itinerary is:
- Setting up an environment to explore the basic operations of Chef - using the Chef Development Kit (ChefDK)
- Exploring the basics of how Chef works to install Java and WebLogic Server on a single node
- Installing and examining some (more...)
Quite recently, I stumbled across this older but still very relevant whitepaper on the workload management capabilities of WebLogic Server. Written by one of the key engineers at the time, who later went on to become an architectect, it explains the workings of the new work load management feature introduced into WebLogic Server at the time and covers the concepts of work-manager configuration and effect, work scheduling and prioritization, overload protection and more.
In an earlier post on the topic of Using JAX-RS 2.0 with WebLogic Server 12.1.3
, I described that we've utilized the shared-library model to distribute and enable it.
This approach exposes the JAX-RS 2.0 API and enlists the Jersey 2.x implementation on the target server, allowing applications to make use of it as when they are deployed through a library reference in a weblogic deployment descriptor.
The one resulting (more...)
Following from my last posting
, I thought I'd also show how Eclipse (OEPE) makes the new Java EE 7 APIs available from Oracle WebLogic Server 12.1.3.
The first step was downloading and installing the Oracle Enterprise Pack for Eclipse (OEPE) distribution from OTN.http://www.oracle.com/technetwork/developer-tools/eclipse/downloads/index.html
Firing up Eclipse, the next step is to add a new Server type for Oracle WebLogic Server 12.1.3, pointing at a local installation.
Oracle WebLogic Server 12.1.3 provides full support for Java EE 6 and also adds support for a select set of APIs from Java EE 7.
The additional APIs are:
- JSR 356 - Java API for WebSocket 1.0
- JSR 353 - Java API for JSON Processing
- JSR 339 - Java API for RESTful Web Services 2.0
- JSR 338 - Java Persistence API 2.1
See the "What's New in 12.1.3 (more...)
One of the new capabilities of Oracle SOA Suite 12c
is the ability to control the SOA infrastructure thread pools, except the resource pools for EDN and the adapters, with Oracle WebLogic Server work managers. Each partition will has its own work managers defined. This allows you to separate services in partitions and, to some extent, tune them separately based on for example specific SLA requirements.
Well, this blog posting is not about explaining the (more...)
Another feature of WebLogic Server 12.1.3 that I'm sure developers will find useful is the inclusion of an implementation of JSR-353 Java API for JSON Processing.JSR 353: JavaTM API for JSON Processing
This new API, working from the foundations provided by earlier implementations such as Jackson, Jettison and Google JSon, now provides a standard API for working with JSON from Java. This goals and objectives of the API described in the initial (more...)
As part of the JAX-RS 2.0 support we are providing with WebLogic Server 12.1.3, one really useful new feature is the new Client API it provides, enabling applications to easily interact with REST services to consume and publish information.
By way of a simple example, I'll build out an application that uses the freegeoip.net
REST service to lookup the physical location of a specified IP address or domain name and deploy (more...)
We've been working on adding some Java API updates to the coming WebLogic Server 12.1.3 release.
One that I think is going to be very popular is JAX-RS 2.0
, which includes some useful new capabilities around filtering, interception and a really useful new client API.
In the WebLogic Server 12.1.3 release we are providing this in the form of an optional shared-library that contains: the JAX-RS 2.0 API, (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...)
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...)
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

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.

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...)
