Oracle apex 19.2 using EPG gateway stopped working after upgrade from Apex 5
I am having a weird problem with my Apex in PROD.
After I upgraded my PROD the apex login pages worked for a couple of days and then not responding. The page dies with page not ound
A clone from the PROD works great again.
Checked the few database parameters that I know
LOCAL_LISTENER
DISPATCHER
SHARED_SERVERS
Is there a log file to check for any errrors ?
