The Oracle Storage Cloud Service is an IaaS offering that underpins [almost]every other PaaS Cloud Service from Oracle. I have been using this service – largely indirectly – with DBaaS, JCS, Application Container Cloud (ACCS) and SOA CS. The initial interaction is usally using Curl against the REST APIs of the Storage Cloud Service. For one off tasks, that works fine. However, while going through development cycles with a Node.js application running on ACCS, (more...)

The DBaaS instance is in archive log mode – and has created quite a chunk of archive log files over the last few months – now causing (more...)

I recently was working on a Node.js application that exposed a REST API to HTTP consumers. The consumers could send POST requests with a (more...)
My objective: be able to very quickly run Node.js applications that can connect to an Oracle Database – with minimal disturbance of my laptop environment (Windows 7).
The solution discussed in this article: use Vagrant on Windows – together with VirtualBox – to create a Linux Host VM, install Docker in that VM and provision a Docker Container with Oracle Linux 7, Node.js and the node-oracle package (the Oracle Database Driver) with the (more...)
