Recently someone was asking me this question via e-mail: "On my home page I have defined a couple of PL/SQL processes that take a long time - like 30 seconds - to finish. These processes fill up some collections that are used on the page to show information. But how can I let the user know that the system is "working", because right now they're watching at an empty screen (or the login screen) for 30 seconds." Apart from speeding up the queries, there are two approaches to solve this (that I know off) : The first one is using AJAX calls.

It has been a while, but this year AMIS and SMART4APEX are organizing an ODTUG KScope Preview event together. This event will be held on Thursday, June 12th at the AMIS offices in Nieuwegein.
