When advising customers on ADF projects, I often find development environments where many or all developers are working against the same database. That introduces a hard dependency between different parts of the project – if one developer deploys a defective PL/SQL package to the database, nobody else can run the application.
This approach made sense back when hardware was expensive and databases had to be managed by high priests in glass-walled, climate-controlled rooms. Today, you can buy a development machine with a quad-core i7, 16GB of RAM and a 256GB SSD disk for $1,200. This machine can easily run an enterprise-class database, application server and IDE. Additionally, virtualization software allows you to build, distribute, and reset environments easily.
It doesn’t make sense to have expensive developers work on old hardware. As soon as they have lost a day due to an inflexible development environment, you have lost more than the cost of a proper development laptop.
Don’t waste expensive developer time because you’re too cheap to buy proper hardware.
