Internal Apex Process(?) Killing Resources.

Question

Hey All,
I got an email from my DBA today asking if I have any idea what the following code is and what it does. I see the use of the "f" procedure so my best guess is that this is what apex uses to render pages? That aside, the problem is that according to my DBA when this runs it causes background process to "go crazy". In asking him to dfine "go crazy" he responded with this:
"Log writer (LGWR), and DBwriter (DBWn). That tells me its doing a bunch of writing, so much so that we need to switch logs often."
Anyone familiar with this or know what could cause that?

Hi Jen,
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.
Regards
Andre
