ADF BC Tuning IX: Application Modules, Part 3

This is the last in a series of posts about tuning business components. The complete list:

The last post was about understanding application module pooling, so I’m going to assume you understand it now. And if you understand application module pooling, you can understand the pain points from a performance perspective, and you can gain some idea of how to balance out differing concerns. Here are the pain points, in decreasing order of importance.

ADF BC Tuning VIII: Application Modules, Part 2

Last week, I talked about a couple of tuning opportunities for ADF application modules: Lazy loading and shared application module instances. This week and next, I’m going to talk about a way to tune your application modules that is, in my opinion, even more important: Knowing how and when to adjust your application module pool settings. This week, I’m going to write about what application module pooling is; it’s pretty vital that you understand it before you try to tune it. Next week, in the final post in the ADF BC Tuning series, I’ll provide the actual application module pool tuning tips.

ADF BC Tuning VII: Application Modules, Part 1

It’s been a while since the last installment of ADF BC Tuning, but it’s time to start it up again. I’ve already posted tips for tuning entity objects, associations, view objects (in three parts), and view links, so now, let’s turn our attention to the last of the major business components: application modules.

3000 Developers!: Kaleidoscope ’09 Report II

Last week, I talked a bit about the two talks I saw at ODTUG Kaleidoscope 2009 on Monday, Lucas Jellema‘s “That’s Rich! Putting a smile on ADF Faces,” and Duncan Mills‘ “Fusion Design Fundamentals.” My focus was the debate about whether and when to use custom Javascript and ADF Faces RC client-side objects. But both talks had a lot of interesting information outside the debate. In this post, I’m going to talk about Duncan’s account of the ADF methodology used by the team  at Oracle responsible for Oracle Fusion Applications–a massive rewrite of Oracle’s business applications based on ADF with the Fusion stack (that is, ADF all the way from bottom to top: business components, model, task flows, Faces RC). This team is is especially notable for its size–3000 developers–which makes a proper methodology even more critical than usual. Next week, I’m going to go into more specific detail about the client-side programming tips Lucas demonstrated.

Framework for Package-Based ADF BC, My ODTUG Schedule, and More

Like the poltergeists, I’m baaack. I’m back to my usual health, and while I’m still pretty horribly snowed under, I think that enough of the worst of it is over that I can generally commit to my “Updates Mondays” schedule again. This has been a *long* hiatus (over 6 motnths), and I’m very glad to be back among the lang of the living. I’ve missed this blog and the ADF community generally.

Although I plan to get back to the ADF BC Tuning series soon, I want to use this post to announce two things: The first piece of software I’m releasing on this site and my public (that is, not just as an audience member) at ODTUG Kaleidoscope, which will be next week in Monterey, CA.

First, the software. This is actually related to one of the talks I’ll be giving at ODTUG, and tangentially related to another. But even if you aren’t going to the conference, I hope you’ll find it useful. It’s an extension of the ADF BC framework that allows you to create the following 100% declaratively:

  • Entity object definitions (including support for optimistic or pessimistic locking and Refresh After… settings) that use Package APIs instead of DML
  • View object definitions (whether entity-based or not, and including support for query parameters) that use Package APIs instead of SELECT statements
  • Associations and view link definitions involving the above

You can get the framework here.

At ODTUG, I’ll  be participating in the following:

Hope to see you there!
