I'm very much a newbie with APEX. Have a simple tool that will be ready shortly to be live on the apex.oraclecorp.com site. Is there a web page, or other forum specifically for internal users?
I'm considering using SSO authentication. The wizard says the app needs to be registered, but there's no additional guidance on how to get that done, or what's involved in that process.
apex.oraclecorp.com is the Oracle internal website for Oracle Confidential inwards facing applications that you should use, assuming you are an Oracle employee. If you go to that site it explains the conditions of use and how to apply for a workspace. SSO is the recommended authentication method and if you simply go to the Oracle search facility on my.oracle.com and search for "SSO apex" you will be given links to blog and forum articles on how to implement this for your application.
There are internal forums and blogs you can access that give information on APEX, but I would recommend this forum for general technical questions and information as it has a large and active community, both internal and external to Oracle. Also, you should update your profile to give more friendly forum name rather than user12602263.
1) There's an internal mailing list for Oracle employees - email@example.com. [Any non-employee reading this, don't bother trying - it can't receive emails outside of Oracle]
2) To hook up SSO in your application is a piece of cake. Just follow these same instructions: http://joelkallman.blogspot.com/2009/04/oracle-single-sign-on-and-apexoraclecom.html
