Perhaps simply a problem on your part, due to a lack of reading and comprehension.
As you exhibited with this posting, asking a product related question in a forum that explicitly states...
Community Feedback (No Product Questions)
Welcome! The Community Feedback space is intended for discussions about the Oracle Developer Community, not for product-specific questions.
There are tips on how to find the correct space on the Getting Started page.
In the ACTIONS box on the right of your post, you should be able to click on "Move", and then specify the correct space, so experts in that product can see your question. (A moderator here can also move the post for you if you specify which Oracle product you're using.)
Thanks and good luck!
User, you have posted your question in the wrong space and already got the right hints how to look for the right space yourself. As this thread already has too many answers which have nothing to do with your question, I'll lock this thread and advice you to open a new discussion in the right space.
