Today I had to babysit a demo machine I set-up for a proof of concept. All went well, as I expected.
A two gigabyte RAM Linux machine with SOA/BPEL 11g, two WebLogic 10.3 domains extended with ADF and Apex XE running on it. It kept running, but at one point is had only 30 megs of memory left!
Check out ‘Extending your WebLogic standalone environment with ADF runtime libraries‘ for more information about setting up the WebLogic environment with ADF.
