APEX

Hello All,

I am trying to use region caching (SQL report region) to save some time on a query. I have region set to Cached by User, condition=Always. I am certain that it is JUST NOT CACHING. Subsequent calls to the same region are taking the same time as the first time. Also, I ran the built-in APEX_APPLICATION_CACHING reports and nada-- no caching.

Are there certain conditions under which caching just doesn't work? Here are some that I wonder about which I have in my setup:
- the report region source is using a dblink to another db; the data is not local to APEX.
- i am calling the function via a js "doSubmit" function.

Would I need to enable page caching in order for region caching to work?
Would these cause caching to be ignored or skipped?

TIA for your help!
