I made a small application in APEX 4.2.2. on database 11g XE.
Everything works great except for one thing. After a few opening form (clicks)
application stop and wait about 30 seconds and then move on. Why?
Application used by one user on a laptop.
Quite is frustrating to work on such an application.
Does anyone had a similar problem.
The usual cause of such problems on XE is an incorrectly set SHARED_SERVERS parameter. If you're using EPG check the SHARED_SERVERS configuration.
A value of 10 should be more than adequate for a single user system.
