Re: Configuring Oracle Portal and Oracle 9ias

Hi!

The main issue with Portal in my experience is it's scalability problems. When you are developing, alone in your Portal and in fast local area network you probably don't see any performance problems, but when hundreds or thousands of users start using your portal, over slow wide area network you might even find out that your app is completely unusable. This is for two reasons, since everything is so dynamic, every time a page is generated, huge amounts of CPU are used, and we can't much tune it either, because the SQL is in wrapped PL/SQL packages. That's why Oracle is promoting their WebCache so much with iAS, but once you cache, you won't be completely dynamic. So have to balance between performance/caching when desining your app.
The other issue is, that for every page display, Portal is doing a lot of HTTP requests toward the server (authentication to single sign-on server for for example, and often separate request for every tiny detail on your webpage).

This experience comes mostly from iAS v1, hopefully the core page rendering engine has been optimized better in v2.
If you want this to run on your laptop, you probably need 1GB of memory in it.

Tanel.
