Oracle NoSQL Database is an interesting option to consider when you want a schemaless, fast, scale-able database which can provide relaxed (eventual) consistency. Oracle provides a Node.js driver for this database. In this blog I’ll describe how to install Oracle NoSQL database and how to connect to it from a […]

Node.js: My first SOAP service

Maarten Smeets

I created a simple HelloWorld SOAP service running on Node.js. Why did I do that? I wanted to try if Node.js was a viable solution to use as middleware layer in an application landscape. Not all clients can call JSON services. SOAP is still very common. If Node.js is to […]

This article explains how the process of doing performance measurements of an OSB Proxy Service and presenting them in a “performance analysis document” was partly automated. After running a SoapUI based Test Step (sending a request to the service), extracting the service performance metrics was done by using the ServiceDomainMBean […]

How to use WLST as a Jython 2.7 module

Maarten Smeets 15

WebLogic Scripting Tool (WLST) in WebLogic Server 12.1.3 uses Jython version 2.2.1 (based on Python 2.2.1). This can be an important limitation when using WLST. Many modules are not available for 2.2.1 or are difficult to install. See here for an example. WLST however can be used as a module […]
