Test your WebLogic 12.1.3 enviroment with Robot

Robot Framework is a generic test automation framework which has an easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach. This means we can write our tests in readable and understandable text. If we combine this with the REST Management interface of WebLogic 12.1.3 we are able to test every detail of a WebLogic domain configuration and when we combine this

Create with WLST a SOA Suite, Service Bus 12.1.3 Domain

When you want to create a 12.1.3 SOA Suite, Service Bus Domain, you have to use the WebLogic config.sh utility.  The 12.1.3 config utility is a big improvement when you compare this to WebLogic 11g. With this I can create some complex cluster configuration without any after configuration. But if you want to automate the domain creation and use it in your own (provisioning) tool/script then you

Oracle SOA Suite 12c tips – Tuning the SOA infrastructure thread pool

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...)

Configure Coherence HotCache

Coherence can really accelerate and improve your application because it's fast, high available, easy to setup and it's scalable. But when you even use it together with the JCache framework of Java 8 or the new Coherence Adapter in Oracle SOA Suite and OSB 12c it will even be more easier to use Coherence as your main HA Cache.  Before Coherence 12.1.2 when you want to use Coherence together with

REST, SSE or WebSockets on WebLogic 10.3.6

WebLogic 10.3.6 comes with Jersey1.9 and has no support for Server Side Events or WebSockets. But for one of our projects we are making a HTML5 / AngularJS application, which need to invoke some RESTful services and we also want to use of SSE or WebSockets. Off course we can use WebLogic 12.1.2 but we already have an OSB / SOA Suite WebLogic 10.3.6 environment. So when you want to pimp your

new Puppet 3 Weblogic provisioning module

The last few weeks I was busy re-writing of my puppet WLS module so it fully supports the power of Puppet 3 (thanks for more than 4000 downloads on puppet forge and all the github downloads). With Puppet 3 we now can use Hiera, Iterations and Lambdas expression. This does not (more...)

The road ahead for WebLogic 12c

Before we can describe all the new features of WebLogic 12.1.3 & 12.1.4 and compare this to the 12.1.2 version we should first take a look at the 10.3.6 version. WebLogic 10.3.6 is still the latest 11g version but Oracle (more...)

Custom Jersey WADL generation

I had a situation where the auto generated WADL did not match with my Rest services. The first difference was that the response is presented as an object instead of a collection of objects and the second one is that it could not handle JSONWithPadding as response.  Because I use (more...)

Coherence 12.1.2 Rest application build with OEPE

With WebLogic 12.1.2 Oracle also released a new version of Coherence and OEPE. The 12.1.2 release contains many new Coherence features like WebLogic Managed Coherence Servers and Coherence Grid Archive ( GAR ) which can be included in an normal EAR. Coherence also has some nice (more...)

JAX-WS SOAP over JMS

With WebLogic 12.1.2 Oracle now also supports JAX-WS SOAP over JMS. Before 12.1.2 we had to use JAX-RPC and without any JDeveloper support. We need to use ANT to generate all the web service code. See this blogpost for all the details. In this blogpost I (more...)

Custom OSB Reporting Provider

With the OSB Report Action we can add some tracing and logging to an OSB Proxy, this works OK especially when you add some Report keys for single Proxy projects but when you have projects with many Proxies who are invoking other JMS or Local Proxies than the default reporting (more...)

Using the Apache HTTP Server (mod_proxy) as a reverse proxy to a WebLogic Server

If you are using a WebLogic Cluster you need a proxy in front of the cluster to provide load balancing. You need either a hardware load balancer or a Web Server with the Oracle Web server plug-in.

Even if you are not using a Cluster it makes sense to place (more...)

Oracle OpenWorld Submissions – The Full Monty

Here one day before deadline, I have entered almost my entire current catalog of presentations for consideration in the Oracle OpenWorld 2013 agenda. One new for this year: “Worst Oracle ADF Project Ever” ;-)

If you would like me to speak at one of your events, the following are the presentations (more...)

WebLogic-In-A-Box

Oracle has just announced a new Oracle Database Appliance, this time with WebLogic. So if you are looking to move to WebLogic and want a high availability environment, read on.

Like the previous editions of the Oracle Database Appliance, this is a physical 4-U rack mounted box that comes with (more...)

Work Managers in WebLogic Server

I found a brilliant Work Manager demo video by James Bayer. There also is a accompanying slide show.

James also has an older post where you can download the source and the war file. It is great when you can get your hands on the source of demos so you (more...)

Getting the size of the HTTP Session State in WebLogic

I recently had to find the size of the data stored in the HTTP Session State. On MOS I found this note:
“Session Replication Fails Due To Non-Serializable Object: JSP Test Page [ID 1073386.1]“.
It contains a JSP test page that will show you if your session data is (more...)

Enterprise Manager will not start after ADF upgrade

I recently had to upgrade a WebLogic Server with ADF for a customer. It was WebLogic 10.3.4 to 10.3.6 and ADF 11.1.1.4 to 11.1.2.3. They also used Enterprise Manager.

Everything went fine except for the Enterprise Manager which ended up (more...)

Auditing users in WebLogic Server

If you do a default installation of the WebLogic Server user activity is not audited. WebLogic has a build in Auditing Provider but it has to be enabled.

The Audit Provider can log these events.

To enable it via the Admin Console got to Security Realms => myrealm => Providers (more...)

Is your WebLogic Server slooow? Might be because of low entropy

On Linux low entropy can cause certain operations to be very slow.

SSL operations need entropy to ensure randomness. Entropy is generated by the OS when you use the keyboard, the mouse or the disk.

If an SSL operation is missing entropy it will wait until enough is generated.

If (more...)
