OGH APEX Day 2011

Yesterday it the Dutch Oracle User Group (OGH) organized a full day APEX-only event. And what a day it was! With 250 attendees it was completely sold out. And I guess, if there had been more room, there might have been even close to 300 people there. So APEX gaines more and more interest - and faster and faster...  And where did all those people came for? Before lunch there were three general sessions. The first was by Tony Andrews and Nigel Blair of Northgate, talking about their 1500 Forms-to-APEX conversion project.

If you use a webserver the presence of that directory is easy to see - and to delete.  When using the Embedded PL/SQL Gateway (EPG) the same procedure is applied, but now you probably wont notice, until you look for it... To get rid of the old stuff run (of course use your own images directory instead of mine): begin   dbms_xdb.deleteresource( '/images_201102071025'                          , dbms_xdb.delete_recursive);   commit; end; After running th
