In a few days I will pack my bags and head off to Birmingham for the 2008 version of the UKOUG. I am looking forward in meeting old friends and making new ones. And of course - attend some of the most interesting sessions available in Europe! While I was setting up my agenda for the week I noticed that on every day the first session starts at 9:25. That makes it a lot easier to network at night... My agenda contains a mix of Fusion, DBA, Development sessions and of course APEX (all though there is not that many APEX sessions). It is gonna be a busy week!

APEX 3.2 will contain functionality to migrate Oracle Forms to APEX. I am one of the (about) 10 lucky people that take part in testing the Limited Early Adopter release, so I know what it can and cannot do (I will blog about that later). In 2007 Wilfred van der Deijl did a presentation at ODTUG about the integration of Oracle Forms with JSF, JSP and ADF Faces. This eventually resulted in a product OraFormsFaces . The technique he used is elaboratly described in this Step-by-step guide . So I thought: Why not try to copy this technique and do this also in APEX? So first I created a simple form showing Orders (all is based on the HR scheme). The second step is to incorporate this Form in an APEX region. So I created a page and within that page a PL/SQL region. The region source is a call to a database procedure APEX$CALL_FORM. This procedure has a couple of arguments, like formname, username and password. This procedure simply uses htp.p to put out the same tags that are used to show a f...

Today I received the silver medal on the OTN APEX Forum ! 500 more to become an Expert... Or should I go for an Ace of Spades....

Yesterday over 100 Pro's attended Guru Tom's session on '11 Things about 11g'. But in the hours before that session a small number (about 18) of persons had the honor of listening and discussing with the master himself. As a guide he used an extensive version of his ' Worst Practices ' presentation. During - and after - the presentation there was a lot more Q&A than I've experienced in regular sessions - of course due to the small scale of this session. On a question about the new features and enhancements of 11gR2 Tom told that there will be no export functionality anymore in R2 (import will be available though). For moving data from one instance to another you should use datapump or SQL Developer or APEX. Also he explained a little more about the Online Application Upgrade . This feature will use invisible indexes, cross edition triggers and (a maximum of) two versions of PL/SQL programs and views (tables are not versionable). It sounds like it is not ...
