Oracle APEX, Citizen Development & Governance

There are different kind of developers out there. Here is my definition of these groups: High-code developers Programmers mainly working for example in Visual Studio Code writing C++, C#, Java, JavaScript, PL/SQL, etc. Low-code developers Fullstack developers working in the IT department that like to work with a low-code platform to create applications faster by configuring components and designing simple statements. In small projects, they also act as high-coders to get the final approx. 10% of functionality in place that isn't possible to configure (ie. complex business logic). Citizen developers Employees working in the business department (hr, sales, controlling, etc.) that have deep knowledge about their business processes and are eager to implement corresponding apps themselves. Most low-code projects are done by professional app developers in the IT department. On the other hand, Gartner and Forrester are claiming that we need to embrace citizen developers as there aren'

About sustainability & Oracle APEX

The climate crises is here and immediate counteracting is required to prevent worse. Key is to take into account environmental and social aspects in each buying decision. Above all, a sustainable planet requires developed countries to consume less, a lot less. Starting at 2025, businesses in Europe need to report their carbon footprint besides the usual regulatory financial reporting. Regarding IT, this includes the carbon footprint produced by hardware. A better utilization rate of hardware leads to less hardware required. Companies like Vodafone monitor the utilization rate of their servers as well as the power consumption for each infrastructure component using Oracle Application Express (APEX) to reduce the carbon footprint of their data center. On software level, program code affects the required energy consumption. For example, in terms of database usage, are all records read out even if only one record is required? In terms of storage: do we really need to keep data stored infin

Protect your public server!

During the week, a DDoS attack with over 384 IP addresses from all over the world was started on our public Oracle APEX server. As we do like people (and proper bots) to make use of our free services to provide information about Oracle APEX, the bots managed to request an APEX page around 1.000 times a minute! With that many page views, the connection pool of Oracle REST Data Services (ORDS) with maximum 30 DB connections got full and people were starting to see an error message from ORDS. Of course we could scale up the connection pool with the database, but that would mean we had to scale up our hardware too, as ORDS was already taking up 100% CPU. Instead, my colleague Moritz Klein quickly found a way to throttle-down the requests in our proxy server installed in front of ORDS. We used a module called "event MPM". The configuration looks like this: # event MPM # StartServers: initial number of server processes to start # MinSpareThreads: minimum number of worker threads wh
