Node.js and Oracle NoSQL Database

Maarten Smeets

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 […]

My first NodeJS service

Maarten Smeets

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 […]

Deploying an Oracle JET application to Application Container Cloud and running on Node.js

Lucas Jellema 2

An article from the Oracle A-Team (http://www.ateam-oracle.com/oracle-jet-with-nodejs/) describes how to run a sample Oracle JET application on a Node.js server. I have followed the steps in that article, ran the JET application locally and then configured the application for deployment to the Oracle Application Container Cloud. Subsequently, I created a […]

REST API on Node.js and Express for data retrieved from Oracle Database with node-oracledb Database Driver running on Application Container Cloud

Lucas Jellema 8

This article is a follow up on my previous article Linking Application Container Cloud to DBaaS – Expose REST API from node.js application leveraging node-oracle-database driver. That article describes how a simple Node.js application is configured for deployment on the Oracle Application Container Cloud and how it leverages the node-oracledb […]

Doing performance measurements of an OSB Proxy Service by programmatically extracting performance metrics via the ServiceDomainMBean and presenting them as an image via a PowerPoint VBA module

Marc Lameriks 1

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 […]

Donderdag 16 april/Thursday April 16th – Speedy Joe’s – Using asynchronous interaction in Java EE to turn the world’s slowest restaurant into a super performant place

Lucas Jellema

De Java SIG (Special Interest Group) van AMIS organiseert op donderdag 16 april een bijeenkomst (publiek toegankelijk) over asynchrone interacties in Java EE (web) applicaties. Synchrone interacties in de echte wereld en in IT applicaties kunnen de boel behoorlijk ophouden. Synchroon betekent wachten – en resources vasthouden. Dat kan een […]

How-to set the current database schema of an application using a global context

Harry Dragstra

Question: We have customers who want to work with different database schemas and we want to determine dynamically – depending on a choice during or after login – which database schema the application in a given session should use. Is it possible to set this up in the database? Answer: […]

FTPS with PL/SQL

Anton Scheffer 15

Doing a FTP-job with PL/SQL is not difficult. A basic implementation of RFC 959 can be written in a few hundred lines. See for instance ORACLE-BASE, How to FTP with Oracle PL/SQL or Oracle FAQ’s But what if you want to secure your FTP transmission. Google doesn’t find any pure […]

SQL Challenge: Drilling down into World Cup Football Tag Cloud

Lucas Jellema

In a previous article, I have introduced the World Cup Football tag cloud (https://technology.amis.nl/2014/06/22/sql-challenge-dynamically-producing-a-tag-cloud-for-world-cup-football-matches/). I have shown how tags can be associated with football matches, both explicitly and implicitly – the latter derived automatically, based on the structured information about the matches. The tag cloud can be used as a […]
