UKOUG 2010 Recap - Wednesday

Wednesday I started late, because I skipped the first session to prepare for my second one "Tales from a Parallel Universe: Using 11gR2’s Edition Based Redefinitions". Went also pretty good as well I think, ended nice on time - even, again, with a session chair. And I received some really positive feedback from people like John King and Christian Antognini. Thanks guys!
Then there was a funny debate kind of session between Tony Hasler and Jonathan Lewis about "Does Oracle ignore hints?". In the end it was all about semantics...if you discard bugs, poor or wrong documentation and more or less hidden features and unexpected optimizer processes, Oracle never ignores your hint (which in fact is more a 'directive' than a hint) - otherwise you might say that Oracle actually does  ignore your hint.
After lunch - instead of the good hot lunches we received a school-like lunch bag this time - I chaired my second session : "Edition-Based Redefinition: Testing Live Application Upgrades (Without Actually Being Live)". Because I already was familiar with the subject at hand, there wasn't very much new stuff in there - but I am always curious to see if I missed someting in my own presentation...
The last session of the event I attended was "Still using ratios" by my colleague Piet de Visser. Due to the worst time slot of the week - and the weather -  there were only a few attendees (around 10). The content was good though. He should have the chance to redo that presentation on a better time!
Then the people that didn't left Birmingham (or couldn't) all winded down in All Bar One and O'Neills for some final drinks and talks.
All in all again a good conference qua content and attendees. Always good to catch up with people you only met a couple of times a year during this kind of events. Hope everybody made it back home eventually and already looking forward to the 2011 edition of the conference!

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

APEX 5 New Static File Features

In APEX 4 you could upload files - like CSS files, JavaScript files, Images and whatever else you like - into the APEX Repository. When you navigate to Shared Components, there is a Files section that offers three different options:
CSS Files are always uploaded (and changed !) for the whole Workspace. For Images and Static Files (usually JavaScript) you could choose whether they should be available for the whole Workspace or for a specific Application only. And if you had a lot of files - e.g. a lot of images - then you had to go through the upload process one-by-one. But that's usually a one time only thing. If you make changes to the CSS and JavaScript files - and that's a continuous process in development - then you had to delete the existing file and upload the new one. Over and over again. And meanwhile fighting the cache of the webserver and your browser.  And another irritating issue: You couldn't use relative references in your CSS or JavaScript files as they just…

Using LDAP for Authentication and Authorization within APEX

One of my current customers would like to use their LDAP (Microsoft Active Directory) server for authentication and authorization of APEX applications. Of course we tried to set up a standard LDAP Authenication that's available within APEX. But we couldn't get that to work. Maybe it has to do with the fact that the client stored their Users within Groups within Groups within .... . Or maybe it doesn't do a full tree walk in the directory. Or maybe it is just because it is Microsoft - and not Oracle Internet Directory (OID). So we moved to a custom Authentication using the DBMS_LDAP functions (and some examples from the Pro Oracle Application Express book and Tim Hall - a.k.a. Oracle Base).

One of the issues we encountered that we wanted to use the user's login name, like "jdoe" and not his full name ("John Doe"). And the login name is stored in the "sAMAccountName" attribute. But authenticating using just "jdoe" didn't work. …
