This year’s UKOUG Tech13 conference is kicking off with a free SuperSunday event.
You can choose between 7 streams:
- Hands on Engineered Systems
- Analytics – Pulling the Threads Together
- Database Technology 1 & 2
- Real World Lessons from ADF Ninjas
- Extending APEX out of the Box
- WebLogic Hackathon
The best and most interesting is of course the WebLogic Hackathon
I have been working with a great group of people to prepare the WebLogic Hackathon:
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...)
After input from Jacco H. Landlust and Edwin Biemond I have rewritten my post about entropy.
In computing you often need random numbers. They are used for encrypting stuff but also for lots of other things.
For Linux servers random numbers are default provided by the /dev/random device. /dev/random is a pool of random bits (more...)
All FMW products except the WebLogic server is patched via the opatch tool. From FMW 12.1.2 the WebLogic server is also patched by opatch.
In a FMW installation you can have many Oracle Homes. When you install a patch you need to know which home to apply the patch to.
opatch can help you figure out where to install the patch.
I have a Forms installation that I need to apply a patch (more...)
Patching WebLogic is necessary but not fun. To help out I have created a simple Bash script for installing CPU/PSU patches.
For information about CPU, PSU and SPU patches check this post.
The script is using BEA Smart Update so it is for WebLogic Server 12.1.1 and older. WebLogic Server 12.1.2 has switched from BSU to OPatch.

From WebLogic Server 10.3.6 and onwards it is possible to store JTA transaction logs (TLOG) in a database persistent store instead of in a file store.
If you have many domains running on the same Linux server it can be difficult to see what is running and what is not. I have created a Bash script that lists all WebLogic Server and Node Manager processes.
I have tested it on Red Hat 5 and 6.
In some situations you have to restart a WebLogic server many times to get something working. A quick and dirty way of restarting a server is to kill the process and let the Node Manager start it up again.
When you kill the process you will see this in the (more...)
I noticed that in WebLogic 12.1.2 the old domain Upgrade Wizard has been replaced by a new Reconfiguration Wizard.
I have upgraded WebLogic many times, but I have never upgraded a domain.
If you upgrade WebLogic within a major release e.g. 10.3.5 => 10.3. (more...)
The WebLogic server stores its configuration in files in the DOMAIN_HOME/config directory. The main file being config.xml.
The way configuration changes are handled depend on if you are using the domain configuration locking feature. In Production Mode configuration locking is enabled by default and in Development Mode it is (more...)
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...)
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...)
In previous versions of the WebLogic server an beahomelist file was created that contained the paths to the installations aka. the Middleware home’s.
When you deinstall a WebLogic server the path is not removed from beahomelist, but next time you install (more...)
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...)
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...)
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...)
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...)
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...)
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...)
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...)
