Back in April, I got my first exposure to Taleo during a sales call. I was there with the AUX contingent, talking about Oracle HCM Cloud Release 8, featuring Simplified UI, our overall design philosophies and approaches, i.e. simplicity-mobility-extensibility, glance-scan-commit, and our emerging technologies work and future cool (more...)
Performance is one of the big watchwords in tht IT industry; nowhere is it more often used than in the database arena, and it’s usually not a good sign. End users know nothing, really, of the inner workings of the database yet they are the first to point the ‘finger of blame’ at the database when the processing speed slows or queries take longer than they would like to return data. [For end users performance (more...)
For what seems like ages, the noise around wearable technology has been building, but until recently, I’ve been skeptical about widespread adoption.
Not anymore, wearables are a thing, even without an Apple device to lead the way.
Last week, Noel (@noelportugal) and I attended the annual conference of the Oracle HCM Users Group (@ohugupdates); the Saturday before the conference, we showed off some of our wearable demos to a small group of customers (more...)
Here comes more Maker content for your reading pleasure, this time it’s an OTN piece on Java and the Internet of Things:
The piece features lots of Noel (@noelportugal) wisdom, on making, on IoT, on the Raspi and on Java, his own personal fourfecta. If you’re scanning (shame on you), look for the User Experience and the Internet of Things section.
Here’s a very Noel (more...)
The good people at ODTUG have graciously invited me back as a speaker for the 2014 vintage, and Anthony (@anthonyslai) will be my wingman for our session, Oracle Cloud and the New Frontier of User Experience.
Here are the particulars:

The Java Team recently released a short video compiling selected moments from last month’s MakerCon and Maker Faire. If you recall, we were lucky to be invited to participate in both events, both of which were tons of fun, enlightening and inspiring.

If you have Google Glass, you’ve probably seen this card a few times.
After a while, you begin to expect the card when your right temple starts to get uncomfortably warm. Apparently, Anthony (@anthonyslai), our resident Glass expert and long-time Glass Explorer, has a protip to handle this problem, two cans of cold soda.
Chained and migrated rows in an Oracle database can seriously impact I/O performance, especially with Exadata. In a ‘normal’ Oracle database [read that as "non-Exadata, non-ASM" database] chained rows, in small numbers where that usually means 1% or less of the total rows in a table, are generally a nuisance. The performance hit they generate in such a situation is small and may not even be noticed by the end users. Add more chained/migrated rows (more...)
Some of the strangest ideas (to me, anyway) can be found in the depths of PL/SQL code, be it a package, a procedure, a function or an anonymous block. Granted, such decisions may be the result of budgetary considerations which prevented a more robust and reliable application design. I was looking at some code just recently that made me scratch my head in wonder and disbelief. Let’s look at a similar piece of PL/SQL that (more...)
A recent IT-related survey had in its list of questions one rather interesting offering:
“Are there any safeguards preventing the DBA from accidentally dropping a table?”
That is probably not a commonly considered aspect of data security however it is an issue that should be voiced and addressed. How do you ensure that the DBA doesn’t, or can’t, drop a table accidentally? Oracle has at least two ways to ensure that a table cannot (more...)
While investigating a question on returing unmatched rows between two tables I set up an example where both tables had indexes which could be used to speed up the query and hopefully return the result set in less time than required for a full table scan. To my surprise when the index was used on the table with the missing record the query returned no rows. Not understanding this behavior (as I KNEW there was (more...)
Indexes can be very useful tools to improve query performance, but it can be difficult to test indexes in an environment that exactly mirrors production. Although not the preferred method, Oracle offers in 11.2 and later releases the option of invisible indexes. What are invisible indexes? An invisible index can’t be ‘seen’ by any session by default, so it can be created and remain unavailable until testing is scheduled. This can be confusing since (more...)
I’ve been trying to install open source software. In this case an application called Moodle. I followed the instructions to install it on an Ubuntu Server vm but they were missing a couple of key points.
