Iloon Ellen-Wolf from Oracle Support provided a list of all of the customers who have filed a Service Request against Application Express through Oracle Support over the last two calendar years - all 1,723 of them. And as I often say, it's a virtual who's who of the Fortune 1000.
Recently, Kris Rice was kind enough to aggregate the Oracle Technology Network download numbers of Application Express over the last few years, and it shows a nice trend:
In 3 years, we have doubled the number of downloads of Oracle Application Express. It's difficult to extrapolate this to "number of users" or "number of developers", because a single instance of Oracle Application Express can suffice for hundreds of workspaces and thousands of developers and even more end-users (for example, within Oracle we have one APEX application used by 40,000 distinct users on a daily basis). Other customers download Application Express for their personal use on XE. So the number of developers and users per download is somewhere between 1 and "a plethora."
Activity on apex.oracle.com continues to be very brisk. We typically average well over 4 million page views per week and over 500 new workspaces every week. For the past 7 days:
Total Page Views: 4,882,817
Distinct Applications: 3,644
Distinct Users: 4,141
Number of Workspaces: 10,777
Number of Applications: 37,883
Workspaces Approved: 535
Workspaces Purged: 578
To be purged in a week: 594
535 new users in the past week alone kicking the tires of Oracle Application Express can't be all that bad.
So back to my original question - is anyone using Oracle Application Express? Yes, without a doubt - and it continues to grow.
