Slow rendering of all pages. Any suggestions?

Question

Hi Folks.
Just after any ideas you may have.
Application Builder and APEX Admin are fine. They render page requests almost instantly.
Front end, however, is now taking a little over a minute to render each and every page. Login 62 seconds, post-login screen 65 seconds, subsequent screens roughly 63 seconds each.
I have had a look at the SYSAUX tablespace where the Flows schemas reside. This is presently using 3025MB of a 3070 allocation. Currently 98.54% used.
I can access the tables using OEM and SQLDeveloper with no delays.
I will, of course, be getting our DBA to have a look on Monday morning but I wondered if, in the meantime, any of you had come across anything like this and what the cause/solution was.
Many thanks

Hi,
The trace file will be written to the location identified by the Oracle parameter user_dump_dest. The initialization parameters can be set in the init.ora file. The trace file produced can be converted to a readable format using the tkprof program. Search google for "oracle tkprof" to have examples on how to use it.
But regarding your problem, you can also enable the debug mode. Viewing a page in Debug Mode enables you to track what the APEX engine is doing as it renders a page. You can access Debug mode by clicking the Debug link in the Developer Toolbar. This functionality displays time codes that correspond to specific APEX engine actions. This way you can see where your application is getting long to render.
You can also use f?p syntax to run an application in Debug mode. Simply call the page and set the Debug argument to YES. For example: f?p=100:1:&APP_SESSION.::YES
