Introduction XQuery transformations are often used in pipelines in Oracle Service Bus to perform data transformation. Performance of XQuery transformations is a key area to focus on when performance tuning an Oracle Service Bus environment. Main Article During performance testing of your project you should use the activity timing metrics to identify any XQuery performance issues and optimize those queries for better performance. The recommended approach is to measure the...

Introduction Occasionally I need to change the port that my WebLogic AdminServer is listening on, without actually starting up the server. Usually this is because I have just created a new domain, and I forgot to change the port in the Domain Configuration Wizard (oops!), and now I can’t start the server up because there is already another one using that port. One way to get around this is to use the WebLogic Scripting Tool (WLST) to change the listening port. Main Article...

Introduction At different process steps, Oracle BPEL engine dehydrates (stores) information about process instances in a database, and retrieves them when the process instance is ready to resume. The dehydration store is critical to Oracle BPEL integrity and performance. Over time, the dehydration store can grow and affect overall performance of the solution. How do you manage the data growth in the dehydration store? Main Article My colleague Deepak Arora (see his blog...

Today, I was installing the Oracle Database 11g R2 on a Solaris system, but it failed a prerequisite check during the installation – it did not have enough swap space available. This particular system I had installed with ZFS. Turns out that adding extra swap space on a ZFS system is slightly different than what you might be used to. I am sure I am going to want to do this again some time, and I guess other folks will too, so here are the details. Firstly, check where your...

Introduction Here is a solution to problem deploying composites on Amazon EC2 due to Elastic IP address. Main Article Sometimes, when running WebLogic Server on the Amazon Elastic Compute Cloud, you may find that you are unable to deploy from your local JDeveloper to your WebLogic Server instance. Andrew Rosson has written a helpful post (here) that provides a simple solution.

Introduction I was working with a very large VMWare image today, containing Oracle E-Business Suite R12. The image is located on an external USB drive, simply because it is too large to fit on the internal disk on the available host machine. It was running very, very slow, in fact so slow that it was completely unusable. A little bit of research turned up some settings that can be used in this kind of situation. Main Article The problem seems to be that VMWare creates a...
