Oracle Application Express (Oracle APEX) is a rapid web application development tool for the Oracle database. Using only a web browser and limited programming experience, you can develop and deploy professional applications that are both fast and secure. Oracle APEX is a fully supported, no cost option of the Oracle database. Learn more at: http://www.oracle.com/technology/products/database/application_express/index.html

There are two new white papers that describe how to deploy PeopleSoft in an Oracle Database MAA configuration to achieve maximum availability for both unplanned outages and planned maintenance activities. Check them out at the links below:

Auditing can be important, but, as in everything else, having several systems helps, as does never putting all eggs in one basket. Case in point: Turning off SYS auditing from the DB without that fact being recorded, over at Paul M. Wright's Three Tier Oracle Security in London blog.
SOA 11g cloning over at the SOA@Oracle SCA, BPEL, BPM & Service Bus blog. You don't need a government grant to do the cloning with all the associated controversy. You don't even have to wonder if you are crossing some thorny ethical border by cloning. You can just clone it.
It doesn't have a centerfold (no, not even with raw devices), but it's as glossy and entertaining as our folks can make it while still satisfying our customers' inner geek. It's Oracle Magazine, and the latest issue is linked from here: May/June 2010 Issue

Dimitri Gielis has an excellent blog we've linked to before, Dimitri Gielis Blog (Oracle Application Express - APEX). He's running a series on the countdown to the public release of 4.0 that is well worth reading: CD APEX 4.0: Feedback feature and Team Development
Troubleshooting RDBMS Memory
Tanel Poder recommends an article by Randolf Geist on Oracle memory troubleshooting. I somehow missed it before: Oracle memory troubleshooting article.
James Morle blogs on Log File Sync and AWR – Not Good Bedfellows and starts a discussion you may want to join (and experiment with the results yourself) on AWR. There is an overarching issue that you can see from this article: Always have a set of tools and never depend totally on one tool for performance monitoring and measurement, not even if Oracle made the tool. There are always other factors and there are always going to be specialized tools that are best for a particular situations (i.e. don't try to pry out flat screws with a phillips screwdriver).
Writing some scripts involving copying data (very few exist without that function). Here's an interesting post on some of the under the hood activities and performance of Linux sendfile and splice over at the Superpatterns blog: Zero-Copy in Linux with sendfile() and splice()

Tom Kyte is putting the finishing touches on the second edition of his magnum opus, Expert Oracle Database Architecture. You can preorder a copy at Amazon here.
Speaking of Oracle guruhood, Cary Milsap has an update on his blog about Filter Early
The title reminds me of the old Chicago voting motto: Vote early and vote often.
New release out:
Oracle Database Patch Set 10.2.0.5 has been released on the following platforms:
· Oracle Solaris x86-64 (64-bit) and SPARC (64-bit)
· HP-UX Itanium
· IBM AIX on POWER Systems
All are available for download from My Oracle Support (patch 8202632) as well as edelivery.oracle.com.
Next up will be Windows...stay tuned
Just one item this week. Over at Glenn Schwartzberg's Essbase Blog Glenn has a moment of revelation about exports: Data Export, why I never thought of it
Eddie Awad has a good article on Please Request a Reasonable Conversion, including some drill-down links at the bottom for further research.
David Peake let's us know that APEX 4.0 comes to http://apex.oracle.com
Also in the realm of APEX is this article from the APEX Development blog:
APEX 3.2 Quick Picks Updated.
Book Review: SQL Developer
Olaf Heimburger's Blog has a brief but useful review of the book Oracle SQL Developer 2.1.
We frequently link to posts at Jim's PeopleSoft Journal. Since he has a new book out, I'm sure it's worth taking a look at: PeoplesTools Tip Book
Flashback – Careful about Storage
A customer recently encountered problems with running out of space for Flashback Database logs (though it took a while to determine that was the problem). Here are a few interesting links that popped up when I was researching the problem:
and this one is excellent, and comes from Jonathan Lewis, one of the key gurus of the Oak Table Net performance group:

Oracle Performance Survival Guide: A Systematic Approach to Database OptimizationBy Guy Harrison
The new book Oracle Performance Survival Guide offers a structured, systematic, start-to-finish methodology for optimizing Oracle performance as efficiently as possible. Leading Oracle expert Guy Harrison shows how to maximize your tuning investment by focusing on causes rather than symptoms, and by quickly identifying the areas that deliver the greatest “bang for the buck.”
Writing for DBAs and developers with all levels of experience, Harrison covers every area of Oracle performance management, from application design through SQL tuning, contention management through memory and physical IO management. He also presents up-to-the-minute guidance for optimizing the performance of the Oracle 11g Release 2.

In the course of researching a client problem I came across a good internals blog. Consider this article, which goes into how to examine the system state on a RAC system and concludes with some wisdom on caching in RAC sequences: Dynamic_plan_table, x$kqlfxpl and extreme library cache latch contention.
As always, Oracle internals is a realm that is somewhat abstruse, and when you have a problem the best thing to do is do a little MOS and Web research to see if there is an obvious solution and then open an SR at the appropriate level to get Oracle Support engaged. That way you are researching in parallel and, hopefully, will find a solution that much faster.
This week at the Oracle E-Business Suite Technology Blog:
