XSLT View is one of two graphical views provided by the new 12c XSLT Editor.  (For a quick introduction to the graphical views in the 12c XSLT Editor see here.) XSLT View provides the ability to edit any XSLT file graphically. It is intended for XSLT developers who have a general understanding of XSLT and have written XSLT source code in a text editor. XSLT View is effectively a graphical source view. It has many advantages over editing XSLT source in a text editor.  Many...

In my previous article, First setup of a connection from Node.js to an Oracle Database, I demonstrated how to make a connection to a remote database using Node.js and the node-oracledb module. I used a dedicated VM with Linux 7 installed and Oracle Instantclient provided the 12.1 client libraries. Now it’s time to take it a step further. Let’s create an application container and just start it multiple time running any .js script and be able to connect to an Oracle database. I...

Measuring performance of services can be done in various ways. In this blog article I will describe a method of measuring Oracle SOA service response times with Splunk a popular monitoring tool. In order to monitor service response times with Splunk, Splunk needs to obtain its data from somewhere. In this example I’ll use the HTTP access log which I expand with a time-taken field. Disclaimer; my experience with Splunk is something like 2 hours. This might also be an...

With the trend of container technologies going on it is great to see Oracle is providing the so called Application Container Cloud Service. Its current architecture is based on Docker and allows to run Java SE and Node.js applications in its current version. See the the following diagram The Load Balancing, dockerizing and scaling is fully transparent. From developer perspective you are deploying a ZIP containing a manifest.json with a command property that states what should...

The Oracle Quick Start installers for Developers are great for probably many developers, but they are limited. Shutting down (or crashing of) JDeveloper will shutdown the domain and there are separate Quick Start installers for SOA and BPM suite. When installing a SOA or BPM environment for development or research purposes i prefer an environment which is more close to a production configuration. Setting up an new environment can take some time when you have to go through the...

Microservices implemented in JavaScript running on NodeJS are becoming quite popular lately. In order to gain some experience with this, I created a little in memory NodeJS cache service. Of course statefulness complicates scalability, but if I would also have implemented a persistent store to avoid this, the scope of this blog article would have become too large. Please mind that my experience with NodeJS is limited to a NodeJS workshop from Lucas Jellema and a day of...

Introduction Using the multi-tenancy features of WebLogic Server 12.2.1, administrators can use domain partitions to share computing resources in the WebLogic domain across different tenants. Administrators can also simplify administration and management by consolidating multiple WebLogic domains into multiple domain partitions in a single domain. Yet sharing the same resources across multiple partitions works against isolating the partitions from each other for security...

Since a few years cloud computing has become more and more popular. The main types of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). In the past, several subareas have been established in the market and pushed by research companies. One subarea is Integration PaaS (IPaaS)  and a variety of vendors have provided solutions. One advantage of IPaaS solutions is the simplified integration. Furthermore,...
